Clearing the Air: Understanding Volatile Organic Compounds (VOCs) – Examining Pollution, Health Impacts, Safety Limits, and Industrial Solutions for Risk Mitigation

When we think about pollution, we have thoughts about its various sources and main pollutants, such as transportation, industrial pollution, CO2, SO2, and volatile organic compounds (VOCs). VOCs are small organic compounds that are present in the air and play a vital part in air pollution. We are here to discuss the VOC, its impact on health, safety limits, and solutions to restrict the risks associated with VOCs.

What are VOCs?

Volatile organic compounds (VOCs) are a group of chemicals that highly vaporize into the air. Chemicals like benzene, ethylene glycol, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene. These VOCs are themselves harmful, and some of them combine and form other pollutants as well.

Common products where VOCs are mostly present:

  • Paints, paint strippers, and other solvents
  • Wood preservatives
  • Aerosol sprays
  • Cleansers and disinfectants
  • Moth repellents and air fresheners
  • Stored fuels and automotive products
  • Hobby supplies
  • Dry-cleaned clothing

VOCs as pollutants:

Volatile organic compounds (VOCs) are a group of pollutants that are responsible for air pollution. Some of the sources of VOCs are as follows:

Volatile Organic Compounds (VOCs): Health, Safety & Solutions

Natural Sources-

Volatile organic compounds Natural sources are as follows:

  • Plants: Many plants release harmful chemicals, and some can even absorb them.
  • Forest fires: Natural forest fires are a source of VOCs.
  • Anaerobic moors: Anaerobic moors processes are a source of VOCs.
  • Cattle farms: Cow manure is a volatile source of methane, a potent greenhouse gas.
  • Anything burning: Anything that burns can be a source of VOCs.

Some of the other natural sources include volcanoes and fermentations.

Artificial Sources-

Artificial, man Made sources of VOCs include fuel production, distribution, and combustion, with the largest source being emissions from motor vehicles due to either evaporation or incomplete combustion of fuel and from biomass burning.

Volatile organic compounds (VOCs) are industrial solvents, fuel oxygenates, and by-products from water treatment. They are often found in petroleum fuels, hydraulic fluids, paint thinners, and dry cleaning agents.

VOCs can come from industrial sources such as:

  • Burning fossil fuels
  • Power generation
  • Manufacturing chemicals
  • Crude oil processing
  • Some metal production processes

Other sources of VOCs include:

  • Gasoline, fuels, and solvents
  • Paints, stains, strippers, and finishes
  • Pesticides
  • Personal care products
  • Aerosol sprays
  • Cleaners and room deodorizers
  • New cabinets, furniture, and beds
  • New carpets, rugs, and wood floors

According to Energy Education, a major contributor to VOCs is the evaporation of hydrocarbon-rich liquids. These include:

  • Gasoline from car tanks or refueling stations
  • Industrial solvents such as oil-based paint
  • Barbecue starter fluid
  • Cleaning products

Health Effects of Volatile Organic Compounds (VOCs)

The health effects of VOCs are as follows:

The health effects of VOCs on industrial workers and general people are categorized by short-term exposure and long-term exposure limits. Short-term exposure effects on health are immediate, and they have been for short periods of time, may be a few hours or a few days, whereas long-term health effects can be long-term exposure, may be a few years, to permanent effects on health. Both are categorized as under.

Short-term:
Short-term exposure to various VOCs may cause:

  • Irritation of the eyes and respiratory tract
  • Headaches
  • Dizziness
  • Visual disorders
  • Memory problems

Long-term:
Long-term exposure to various VOCs may cause:

  • Irritation of the eyes, nose, and throat
  • Nausea
  • Fatigue
  • Loss of coordination
  • Dizziness
  • Damage to the liver, kidneys, and central nervous system
  • Cancer

Industrial Safety Limits for VOCs

Safety Guidelines for Industries by CPCB With respect to VOC exposure

The industries can look more closely at the following aspects for the control of VOCs:

  • Closed handling system for chemicals.
  • Improved solvent recovery through the use of some special condensers and subcooling systems.
  • Mechanical seal for chemical handling pumps.
  • LDAR system – Venting of storages with trap receiver and condenser.
  • Training for the laborers and staff.
  • Proper system of loading and unloading of solvents.
  • Proper solvent recovery systems.
  • Work environment monitoring with respect to VOC has to be conducted and compared with the Factories Act’s occupational health standards.
  • All the emissions emitting sources are to be channeled through ducts to a common conduit, and after advanced condensers and/or scrubbing with relevant or proper scrubbing, the treated emissions are to be let into the air.

Solutions for VOC exposure in industrial environments:

Solutions for VOC exposure in industries are as follows:

Proper Ventilation Measures:

Proper ventilation measures, such as LEV (local exhaust ventilation), must be installed in high-exposure areas of industries for worker safety.

Use of Extraction Systems:

Using extraction systems like Filter On India’s Clean Air Solutions in welding fumes solutions, oil mist extraction and dust collection solutions like welding fumes extractors, oil mist collectors, dust collectors, downdraft tables, and ESP filtration systems with HEPA must be used to control VOC exposure in industrial environments.

Follow guidelines set by authorities.

With regards to worker safety, industries must follow guidelines set by different authorities, such as OSHA, EPA, and CPCB, to control VOC exposure in industries.

Industrial safety limits for VOCs are provided by OSHA,EPA, ACGIH, and in the Indian context, CPCB.

As per OSHA, ACGIH, and NIOSH, the permissible exposure limits for VOCs are as follows-

Exposure Limits
OSHA (PEL)for general industry: 50 ppm (240 mg/m3) TWA; Skin for the Construction Industry: 50 ppm (240 mg/m2) TWA; Skin for Maritime: 50 ppm (240 mg/m2) TWA; Skin
ACGIH (TLV)20 ppm; Appendix A3: Confirmed Animal Carcinogens with Unknown Relevance to Humans
NIOSH (REL)5 ppm (24 mg/m2) TWA
NIOSH (IDHL)700 ppm

The OSHA standards for VOCs can be read here.

Another example of regulations relating to VOC safety includes the EPA’s regulation 40 CFR 59. This federal regulation, “National Volatile Organic Compound Emission Standards for Consumer and Commercial Products,” targets overseas manufacturers and importers of certain products and seeks to ensure that such parties remain in compliance with VOC emission standards.

In the Indian context, the CPCB (Central Pollution Control Board) has set the permissible exposure limits for pollutants, so for VOCs, its limits are as follows:

Moreover, there is no legislation for VOC in ambient air in India. As per the National Ambient Air Quality Standard (NAAQS) of India, benzene is the only VOC whose standard has been prescribed as 5 μg/m3 since November 2009.

Understanding Sulphur Dioxide(SO2):Sources Of Pollution, Health Impact, Knowing Safety Limits and Solutions.

Sulphur Dioxide (SO2) is one of the most significant primary air pollutants after carbon dioxide and nitrogen oxides. This harmful gas plays a major role in industrial air pollution and poses serious risks to workers’ health and workplace safety. In this article, we explore how SO2 becomes a threat in industrial environments, its health impact on workers, the safety limits required to control SO2 exposure, and the key government regulations designed to reduce the risks associated with Sulphur Dioxide in industries.

What is sulfur dioxide(SO2)?

Sulfur dioxide (SO2) is a colorless, toxic gas with a strong, choking odor. It's a member of the sulfur oxide (SOX) family of chemicals, which are made up of sulfur and oxygen.

Sulfur Dioxide (SO2) as a Pollutant

Sulfur dioxide has various sources of pollution; some of the sources are as follows:

Natural Sources

Sulfur dioxide is naturally generated through

Volcanic Eruptions

Artificial Sources

There are two types of artificial sources of SO2.

  • Industrial Sources
  • Other Sources

In industries, SO2 is generated through petroleum refineries, cement manufacturing, paper pulp manufacturing, and metal smelting and processing facilities.

Other sources of SO2 include locomotives, large ships, and some non-road diesel equipment that currently burns high-sulfur fuel and releases sulfur dioxide into the air.

Burning fossil fuels (coal and oil) for domestic heating is also a source of SO2

Highest Concentration Of SO2 In The World –

In the world scenario the highest concentration of SO2 is from our country India, then on the second spot is Russia and Third is China.:

India as the largest emitter of SO2 in the world, contributing more than 21% of global emissions mainly coming from coal-based electricity generation.

Sulphur dioxide(SO2) sources and health impact

How are you exposed to Sulphur dioxide(SO2)?

You can be exposed to Sulphur dioxide(SO2) by breathing it in the air or getting it on your skin. People who live near industrial sources of sulfur dioxide may be exposed to it in the air. You are most likely to be exposed if you work in industries where SO2 is produced, such as copper smelting or power plants, or where it is used in the production of sulfuric acid, paper, food preservatives, or fertilizers. People with malfunctioning appliances or chimneys in their homes may also be exposed to sulfur dioxide.

Most SO2 exposures are caused by people breathing contaminated outdoor air.

SO2 Impact on Health:

The impact of SO2 on health consists of short-term and long-term impacts.

Short-Term Impact of SO2 on Health:
Exposure from breathing sulfur dioxide can cause:

  • Burning of the nose, throat, and lungs
  • Difficulty breathing
  • Loss of smell
  • Headaches and dizziness
  • Nausea and vomiting
  • Harm to the respiratory system: As an irritant, sulfur dioxide can affect lung function and cause and worsen respiratory diseases in humans and animals.

Exposure to very high levels of sulfur dioxide can be life-threatening.

Touching liquid sulfur dioxide can cause:

  • Frostbite
  • Irritation of the eyes:

Long-Term Impact of SO2 on Health:
Long-term exposure to sulfur dioxide can cause:

  • Changes in lung function

SO2 emissions that lead to high concentrations of SO2 in the air generally also lead to the formation of other sulfur oxides (SOx). SOx can react with other compounds in the atmosphere to form small particles. These particles contribute to particulate matter (PM) pollution. Small particles may penetrate deeply into the lungs, and in sufficient quantity, they can contribute to health problems.

  • Bronchitis and shortness of breath

People with asthma may be sensitive to changes in respiratory effects due to SO2 exposure at even low concentrations. Sulfur dioxide is not classified as a human carcinogen (it has not been shown to cause cancer in humans).

  • Decreased fertility in women and men:

 Continuous inhalation of SO2 affects fertility rates in women and men.

Solutions for SO2 Exposure at Industries

Safety measures taken by industries Include the following:

Use ventilation systems.

Use of ventilation systems like LEV (local exhaust ventilation) can reduce the exposure to SO2 to some extent, which leads to an increase in air flow capacity in the work environment, which is very important for workers health.

Use of Extraction Systems:

Using extraction systems for air pollution control is the best solution to protect workers from high exposure to SO2-like pollutants, such as  Filter On  welding fume extraction systems, oil mist collectors, and dust collection systems will be very beneficial for industries to reduce the risk of SO2-like pollutants on workers health.

Use the government guidelines.

Using and following the government guidelines from time to time will surely reduce the exposure of SO2 in industries, and it will have a positive impact on society.

Here are some safety precautions for SO2 exposure, including:

  • Using personal protective equipment as required
  • Increasing ventilation in the area or moving a leaking container to a well-ventilated and secure area
  • Stopping or reducing the leak if it is safe to do so
  • Knocking down gas with fog or a fine water spray

Safety limits for SO2 exposure.

As per OSHA, the permissible safety limits for SO2 exposure are as follows:

SO2 OSHA Limits

In India, as per CPCB-Central Pollution Control Board Of Regulation the SO2 Exposure limits are as follows-

CPCB SO2 Exposure Limits

Formaldehyde (HCHO or CH2O): Unraveling the Impact on Pollution, Health, Safety Limits, and Solutions

Formaldehyde Exposure: Health Impact, Limits & Solutions Blog Banner

Formaldehyde (HCHO or CH2O): Unraveling the Impact on Pollution, Health, Safety Limits, and Solutions

In today's fast-paced world, air pollution is a major problem. Various pollutants are responsible for polluting the air; formaldehyde, i.e., CH20, is among them. So here in this article, we will focus on formaldehyde-CH20 as a pollutant, its exposure i.e. formaldehyde exposure, their health effects, safety limits, and effective solutions, all with respect to industrial air quality improvement.

What is formaldehyde-CH20?

Formaldehyde Exposure Explained

Formaldehyde is a naturally occurring organic compound with the molecular formula HCHO or CH2O or in common names methanal. It is made up of two hydrogen molecules, a single carbon molecule, and a single oxygen molecule.

Uses of formaldehyde:

Formaldehyde is used mainly to produce resins used in particleboard products and as an intermediate in the synthesis of other chemicals. Formaldehyde is used in many industries, such as glues and resins, dyes, textiles, disinfectants, building materials, automobile parts, embalming, and laboratories.

Sources of formaldehyde exposure:

According to inchem.org, here are the sources of formaldehyde:

Natural sources

Formaldehyde occurs naturally in the environment and is the product of many natural processes. It is released during biomass combustion, such as in forest and brush fires (Howard, 1989; Reinhardt, 1991). In water, it is also formed by the irradiation of humic substances by sunlight (Kieber et al., 1990).

As a metabolic intermediate, formaldehyde is present at low levels in most living organisms. It is emitted by bacteria, algae, plankton, and vegetation.

Anthropogenic sources

Anthropogenic sources of formaldehyde include direct sources such as fuel combustion, industrial on-site uses, and off-gassing from building materials and consumer products.

Industrial releases of formaldehyde can occur at any stage during the production, use, storage, transport, or disposal of products with residual formaldehyde. Formaldehyde has been detected in emissions from chemical manufacturing plants. Formaldehyde has been detected in the off-gassing of formaldehyde products such as wood panels, latex paints, new carpets, textile products, and resins. While emission rates have been estimated for some of these sources, there is insufficient data to estimate total releases. In some countries, there have been regulatory and voluntary initiatives to control emissions from building materials and furnishings, since these are recognized as the major sources of elevated concentrations of formaldehyde in indoor air.

How are people exposed to formaldehyde?

People are exposed primarily by inhaling formaldehyde gas or vapor from the air or by absorbing liquids containing formaldehyde through the skin. Workers who produce formaldehyde or products that contain formaldehyde—as well as laboratory technicians, certain health care professionals, and mortuary employees—may be exposed to higher levels of formaldehyde than people in the general population.

The general public may be exposed to formaldehyde by breathing contaminated air from sources such as pressed-wood products, tobacco smoke, and automobile tailpipe emissions. Another potential source of exposure to formaldehyde is the use of unvented fuel-burning appliances, such as gas stoves, wood-burning stoves, and kerosene heaters.

Some examples of workers at risk of being exposed to formaldehyde include the following:

  • Agricultural workers who work in confinement livestock production
  • Construction workers who work with resin-manufactured products
  • Workers who manufacture plastics, resins, and foam insulation
  • Morticians in the embalming process
  • Beauticians who apply dyes and smoothing products

Health Impacts of Formaldehyde Exposure on Workers:

Formaldehyde Exposure Health Impacts on workers

There are various health concerns for workers due to formaldehyde inhalation.

As per EPA documentation, the following health impacts have been found due to exposure to formaldehyde:

Acute Effects:

The major toxic effects caused by acute formaldehyde exposure via inhalation are eye, nose, and throat irritation and effects on the nasal cavity. Other effects seen from exposure to high levels of formaldehyde in humans are coughing, wheezing, chest pains, and bronchitis. Ingestion exposure to formaldehyde in humans has resulted in corrosion of the gastrointestinal tract, inflammation, and ulceration of the mouth, esophagus, and stomach.

Chronic Effects (Noncancer):

Chronic exposure to formaldehyde by inhalation in humans has been associated with respiratory symptoms and eye, nose, and throat irritation.

Repeated contact with liquid solutions of formaldehyde has resulted in skin irritation and allergic contact dermatitis in humans.

Reproductive/Developmental Effects:

An increased incidence of menstrual disorders was observed in female workers using urea-formaldehyde resins. However, possible confounding factors were not evaluated in this study. (1,2) A study of hospital equipment sterilization workers did not report an association between formaldehyde exposure and increased spontaneous abortions.

Developmental effects, such as birth defects, have not been observed in animal studies with formaldehyde.

Cancer Risk:

Occupational studies have noted statistically significant associations between exposure to formaldehyde and an increased incidence of lung and nasopharyngeal cancer. This evidence is considered “limited” rather than “sufficient” due to possible exposure to other agents that may have contributed to the excess cancer.

In short, formaldehyde is responsible for the following health effects on workers (Categorization of Health Effects):

Short-term:
Exposure to breathing formaldehyde can cause:

  • Irritation of the nose, eyes, and throat
  • Neurological effects
  • Headache
  • Nausea
  • Increased risk of asthma and allergies

Skin contact with formaldehyde can cause:

  • Skin irritation and eczema

Swallowing formaldehyde can cause:

  • Gastrointestinal irritation

Long-term:

Long-term exposure to formaldehyde can cause:

    • Cancer
    • Bronchitis
    • Shortness of breath
Safety Limits and Precautions for Formaldehyde Exposure:
As per OSHA Standards, here are the precautions and safety measures that should be taken by the employer to control exposure to formaldehyde:
  • Airborne concentrations of formaldehyde above 0.1 ppm can cause irritation of the respiratory tract. The severity of irritation intensifies as concentrations increase. Provisions of the OSHA standard require employers to do the following: • Identify all workers who may be exposed to formaldehyde at or above the action level or STEL through initial monitoring and determine their exposure.
  • Reassign workers who suffer significant adverse effects from formaldehyde exposure to jobs with significantly less or no exposure until their condition improves. Reassignment may continue for up to 6 months until the worker is determined to be able to return to the original job or to be unable to return to work, whichever comes first.
  • Implement feasible engineering and work practice controls to reduce and maintain worker exposure to formaldehyde at or below the 8-hour TWA and the STEL. If these controls cannot reduce exposure to or below the PELs, employers must provide workers with respirators.
  • Label all mixtures or solutions composed of more than 0.1 percent formaldehyde and materials capable of releasing formaldehyde into the air at concentrations reaching or exceeding 0.1 ppm. For all materials capable of releasing formaldehyde at levels above 0.5 ppm during normal use, the label must contain the words “potential cancer hazard.”
  • Train all workers exposed to formaldehyde concentrations of 0.1 ppm or greater at the time of the initial job assignment and whenever a new exposure to formaldehyde is introduced into the work area. Repeat training annually.
  • Select, provide, and maintain appropriate personal protective equipment (PPE). Ensure that workers use PPE such as impervious clothing gloves, aprons, and chemical splash goggles to prevent skin and eye contact with formaldehyde.
  • Provide showers and eyewash stations if splashing is likely.
  • Provide medical surveillance for all workers exposed to formaldehyde at concentrations at or above the action level or exceeding the STEL, for those who develop signs and symptoms of overexposure, and for all workers exposed to formaldehyde in emergencies.
Recordkeeping Requirements
  • Employers are required to do the following regarding worker exposure records:
  • Retain exposure records for 30 years. 
  • Retain medical records for 30 years after employment ends.
  • Allow access to medical and exposure records for current and former workers or their designated representatives upon request.
Solutions to Formaldehyde Exposure:

Here are some solutions for controlling the exposure to formaldehyde.

  • Use ventilation systems: In industries where formaldehyde exposure is greater, using ventilation measures to control formaldehyde exposure is a must. Using ventilation systems like Local Exhaust Ventilation (LEV) can reduce exposure to formaldehyde very well.
  • Follow government guidelines:  Following government guidelines is the best way to protect workers and the industrial environment from heavy penalties. Time-to-time checking of harmful pollutants by tests like Filter On India’s Air Quality Mapping Test Service can show you the exact exposure of formaldehyde and other pollutants and exposure levels.
  • Use of Air Pollution Control Systems: Using air pollution control systems like welding fume extractors, oil mist collectors, and dust collection solutions from Filter On India can reduce exposure to various pollutants, such as formaldehyde, to a great extent.

Clearing the Air: Strategic Approaches to Industrial Fume Management in the Modern Era.

Industrial Fume Management

Clearing the Air: Strategic Approaches to Industrial Fume Management in the Modern Era.

Air pollution (indoors as well as outdoors) has become a great concern for all of human society in recent years. The impact of air pollution ranges from the loss of man-hours in industries to serious threats to the health of human beings and their next generations. Companies looking to improve air quality often turn to Industrial Fume Management: Effective Modern Strategies to guide their safety protocols. This article attempts to explore the aspect of "fumes," which is the most common face of air pollution, its impact on industries and people, and how we can manage the fumes.

What Fumes Are and Why Industrial Fume Management: Effective Modern Strategies Matter

Fumes are aggregates of very fine particles, gas, smoke, mist, vapor of organic or inorganic substances, etc. Since most of the contents of the fumes are very light, fumes remain suspended in the air, we can say fumes are always airborne. In this article, we will study more specifically the fumes generated during various manufacturing processes in industries.

Sources of Fumes

Most of the commonly used manufacturing processes generate some or other forms of fumes / mist / smoke / dusts. Some specific examples – Fumes generated in heat treatment processes like oil quenching, induction heating, and melting process manufacturing processes generate some form of fumes, mist, smoke, or dust. Some specific examples Welding Fumes, Oil, coolant mist, and fumes generated in machining operations Dust and fumes generated in plasma cutting. Fumes generated in the casting and forging industries Acidic fumes generated in plating and pickling processes Dust and fumes generated in dry grinding operations Fumes generated in brazing and soldering And many more such operations.

Industrial Fume Management is important because fumes impact on industries, people and machinery

Impact of Fumes on Industries

The fumes affect every asset of the industry, i.e., man, machine, materials, and image. That’s why managing fumes is becoming more important day by day. Industrial air quality is greatly affected by various types of pollutants, so to learn more about indoor air quality in industries and how to improve indoor air quality to safeguard your workforce, you can read about it here.

Rejections or time lost in production.

In certain industries like food and drugs etc., the fumes can cause rejection of the whole batch of production because it directly affects the product.

Impact of Fumes on People

The presence of fumes beyond certain limits in the work environment can cause various ill-effects, such as increased absenteeism, a lack of concentration on the job, high physical and psychological fatigue, and low morale at the workplace. All this adds up to reduced productivity. Also, many times companies find it difficult to attract and retain employees in certain affected areas.

The fumes affect the individuals in a much more serious way. The people may suffer from short-term disorders such as eye irritation, feeling of nausea, difficulty in respiration, cough, indigestion, etc. However, unfortunately, many times these are neglected. Prolonged exposures may lead to the development of some fatal diseases like asthma, tuberculosis, bronchitis, fibrosis, lung cancer, etc. Certain ingredients in fumes are such that they affect kidney and heart functioning. Since all these impacts are very gradual in nature, they are therefore extremely dangerous. The diseases or disorders are detected very late in many cases. The pollutants in fumes thus act as a slow poison and, therefore, need to be managed properly.

The impact of fumes on workers in an industry is huge. For example, when there are various welding stations in an industry, the fume rate due to welding is very high, so how do we know exactly how much of the impact of welding fumes is on workers? Please read more about it here.

The impact of fumes generated by oil or coolant mist is huge on people working in an industrial environment. They have suffered various symptoms, which are discussed above, so to know more about how you can minimize the exposure and prevent your workers from getting oil or cooling mists, you can refer to our article about it here.

Impact on Materials & Machinery –

Certain fumes can be corrosive in nature like acidic fumes and can damage the materials. This is a direct loss to the industry. Also in some highly corrosive environments, the fumes even affect the structures and can cause a safety hazard.

Deposition of fumes & dust on sensitive electronic circuit boards, components can cause malfunctioning of the controls and can cost an industry in crores on account of rejected products.

Impact on Image & Client perception –

The presence of fumes, dust etc in the work environment in an industry sends negative signals to the clients visiting the facility for assessments or inspections. It creates an impression that the company is not very serious about employee health, safety and environmental issues. 

The above discussion shows how the fumes affect an industry from various dimensions and the industry cannot afford to ignore or sideline the said subject.

Industrial Fume Management: A Roadmap for Managing Fumes and Air Pollution

Managing fumes and reducing their impact is a continuous and ongoing activity since many processes keep adding to the industry. Thus, this exercise should be integrated into the management process, just like cost-cutting, quality improvement, etc.

Managing Fumes Project Process for Industrial Fume Management

A suggested model process is shown above, which will provide an organization with a platform for managing air pollution problems effectively and on a long-term basis.

Remember that managing air pollution, or fumes, is not a one-time exercise.

Managing Fumes: Implementing Data-Driven Monitoring for Safer Work Environments

Adopting Industrial Fume Management: Effective Modern Strategies helps facilities reduce emissions while protecting worker health.

It involves two different and equally important aspects: 

  1. Capture of fumes
  2. Processing or Filtration of Fumes

Capture of fumes

The capture of fumes involves a capturing arrangement, generally a suction hood connected to a blower through ducting. The blower capacity is designed as per the suction hood dimensions, its distance from the generation point, and the type of fumes to be captured.

 The design of the suction hood and the proper capacity of the blower are two of the most critical aspects of the success of any fume extraction system. This is because unless the fumes are captured efficiently, they cannot be treated, and in the absence of effective capture, fumes will escape the suction hood and spread all over the environment, making the fume extraction system ineffective.

 As far as possible, the application from which fumes are generated should be provided with an enclosure. This will reduce the air flow required to capture the fumes and thus optimize the size of such a system. E.g., a welding table can be provided with an enclosure from three sides and a canopy hood on the top.

 Important Point: The design of the suction hood and the selection of a proper-capacity blower have a direct bearing on the effectiveness of the fume extraction system. So it makes sense to spend more time analyzing different designs and options

Some of the typical suction hood designs and related air flow requirements are shown in the attached table 2 below for illustration.

Exhaust volume calculation for Industrial Fume Management

Processing or Filtration of Fumes

It involves the separation of the hazardous contents of the fumes, like dust particles, oil mist, etc., from the air so that the resulting air is safe to discharge into the environment. There are many different methods of filtration of the fumes, like polyester filters, electrostatic filters, scrubbers, etc., depending on the type of fumes, concentration of fumes, etc

Some of the types of filters and their most common applications are given below:

Industrial Fume Management-Types of Filters & Applications

All the above systems have different efficiency levels for different particle sizes, different pressure drop values and different durability, life etc. So different types of filters are used for different types of fumes. Selection of proper filter for proper application thus becomes equally critical factor in success of fumes extraction system. Many manufacturing plants rely on Industrial Fume Management: Effective Modern Strategies to stay compliant with environmental regulations.

Fume Extraction System Design:

This involves the suction hood design, filter system selection, ducting design, and capacity selection of the blower. All these designs and selections have to be properly integrated for an effective fume extraction system. If there is any error in any one of the above, then the performance of the whole system may suffer. E.g., even if the filtration system is properly selected and the suction hood is properly designed, the system may not develop proper air flow if the static pressure of the blower is not sufficient to overcome pressure losses in the total system. Also, many times it is experienced that just a change in ducting results in the system becoming ineffective just because the new ducting is not properly designed.

Conclusion –

Environments of all types affect the industry in more than one way and cause significant hidden as well as visible damage. Managing the fumes thus becomes very important for safeguarding the industries from various ill-effects. The process of identification of sources, prioritization, planning, implementation, and checking will ensure consistency in reducing the impact of air pollution. For implementing effective fume extraction systems, all aspects, i.e., design of the suction hood, selection of a proper filtration system, ducting design, and blower capacity calculation, are equally important and need to be balanced as per the applications. so its very important for  maintenance engineers increasingly reference Industrial Fume Management: Effective Modern Strategies when designing advanced ventilation systems, because the report on Industrial Fume Management: Effective Modern Strategies highlights new technologies that enhance workplace safety.

Robotic Welding fumes are generated rapidly you can check and see in this below video for clarification, This shows how robotic welding fumes are generated

Potential Danger Due to Robotic Welding fumes:

In industrial workplaces, inadequate air filtration and fume extraction pose significant health risks, including respiratory diseases and chronic illnesses. Workers exposed to fumes without proper systems, like a Robotic welding fume extractor, are vulnerable to conditions such as bronchitis and cancer, which negatively affect their morale and well-being. Poor air quality can also lead to discomfort, decreased concentration, and productivity loss. Furthermore, industrial fumes can damage equipment, increase maintenance costs, and trigger non-compliance with health regulations, which impairs a company's reputation and environmental responsibility. Effective solutions like Robotic welding fume extractors are essential for maintaining air quality and ensuring worker safety.

Why Welding Robots Still Need Fume Extraction:

Even though robotic welding is automated, it continuously generates fumes.

    • Robots work without breaks, so fumes accumulate rapidly.
    • Welding cells whether open or closed allow fumes to spread quickly. In open setups, they can contaminate the entire workspace.
    • Without proper filtration or exhaust systems, air quality deteriorates, productivity drops, and workers’ health suffers.

How Does a Robotic Welding Fume Extraction System Work?

Robotic fume extractors operate based on the volume of generated fumes and the rate of clean air output. Two main extraction methods are used:

1. Source Capture Method

In this method, a suction arm captures fumes directly from the welding source.
 Portable extraction systems are ideal for large welding jobs where welders move around frequently.

2. Ambient Extraction Method

Here, stationary fume extraction systems with canopies, hoods, and ducting are used. They capture fumes from the entire robotic welding cell and filter them through a central system.

Common Pollutants in Robotic  Welding Extractions

Robotic welding fumes contain various pollutants such as metal fumes, ozone, and gases.

  • Metal Fumes: These include fine particles (PM2.5 and PM10) that are highly hazardous to human health. Robotic welding fume extractors are essential to remove them.
  • Ozone and Other Gases: Ozone and other gases formed during welding can cause eye irritation and respiratory problems. Fume extraction is necessary to remove these as well.

Key Components of a Robotic Fume Extraction System

A robotic fume extraction setup typically includes:

  • Clean air system (ESP system)

  • Filters

  • Hoods and canopies

  • Ducts

  • Blower unit

  • Electrical panel

Robotic Welding Fume Extractors Explained.

Hoods and Canopies

These structures capture fumes precisely to prevent exposure and health risks.

Ducting

Carries fumes from the welding area to the filtration system.

Filters

The most critical component — filters remove harmful smoke and fine particles.

Suction Hood

Draws in fumes using a blower motor. The size depends on the type of welding machine or setup.

Blower or Motor

Generates the suction force required for fume capture.

Electrical Panel

Controls and monitors the extraction system.

ESP Stacks

Electrostatic Precipitator (ESP) stacks use ionization to capture and remove fine particles efficiently.

Role of Electrostatic Precipitators (ESP) in Robotic Welding Fume Extraction:

An ESP filtration system cleans air containing welding fumes, smoke, and fine dust.

How it works:

  1. Fume Collection: Polluted air is drawn from the robotic welding cell.

  2. Electrostatic Charging: The air passes through an electrostatic field, charging the particles.

  3. Particle Removal: Charged particles adhere to oppositely charged plates, removing even submicron particles (as small as 0.01 µm).

  4. Clean Air Output: Fresh air is released back into the workshop or outside.

  5. Easy Maintenance: Washable metallic filters mean no frequent replacements and low operating costs.

  6. Efficiency: ESPs are highly effective and maintain a clean, safe working environment.

Benefits of Robotic Welding Fume Extraction:

  1. Improved Air Quality & Worker Safety
     Clean air reduces breathing problems, eye irritation, and other health risks improving overall productivity.
  2. Better Equipment Performance & Reduced Downtime
     Washable ESP filters reduce maintenance needs, keeping systems running smoothly.
  3. Compliance with Safety Standards
     Systems must comply with OSHA and CPCB standards.

Choosing the Right Extraction System

Selecting the right extraction system ensures worker safety and operational efficiency. Consider:

  • Air Volume: Determines the size and capacity of the system.
  • Robot Layout: Open or closed cell designs require different solutions.
  • Type of Welding: MIG, TIG, laser, or plasma welding all produce different fume levels.

Centralized vs. Individual Extraction Units

  • Centralized Systems: Ideal for large plants with multiple robotic welding cells.
  • Individual Units: Offer flexibility and source-level fume capture.

Smart Controls and Automation Integration

Modern fume extraction systems feature smart controls, such as remote monitoring, automatic shutoff, and real-time alerts. Ensure these features are considered when selecting your system.
