Air Quality Mapping: Your First Step to a Healthier Workplace

Air Quality Mapping: Your First Step to a Healthier Workplace

Workplace air quality is a serious issue nowadays. In the industrial environment, the workers face several health issues due to poor air quality. So air quality mapping is an important task for every industry nowadays. It provides various benefits to industries, but the most important benefit is “to plan a strategy to control the fumes in the workplace." Air quality mapping is the first step of every industry towards a healthier workplace.

What is air quality mapping?

The following are a few important things that will tell you what air quality mapping is all about.
  • To assess each workstation's actual air quality in order to ascertain the air quality condition of the workplace.
  • Take the readings in Mg/M3 format for each workstation in the workplace.
  • Carefully analyze and study the readings to understand the actual exposure level of each workstation in the workplace.
  • After complete analysis and study, prepare a foolproof air quality map in accordance with the workstation layout in the workplace to make the workplace healthier.

Workplace Air Quality

Why is air quality mapping important?

Air quality mapping is important for the following reasons:

Air quality mapping helps to formulate the targeted fume extraction strategies for those hotspots where the amount of fume exposure is very high. One can easily target the areas with the help of an air quality map.For example, generally, 20% of the workstations in the layout will be responsible for generating 80% of the pollution. AQ Map helps the planner identify those 20% of workstations for ‘targeted action.’

How is the air quality mapping test conducted?

A Filter ON representative comes to your plant and performs the test in the manner described below.

  • He uses a digital aerosol monitor to measure dust concentration at the operator level.
  • He categorizes results into Red Zones (pollution above safe values), Yellow Zones (pollution on the borderline of safe values), and Green Zones (pollution within safe values) on the plant layout.
  • Then Filter ON provides a report with recommendations for lowering exposure levels in red and yellow zones after analyzing the processes.
  • It enables planning for corrective actions like improved ventilation, enclosures, and pollution control devices.

5 Key Ways: To Improve performance of your Fume Extraction Systems

Fume extraction systems are crucial pieces of equipment for any industry that uses metalworking, such as those that perform welding, machining, heat treatment, laser cutting, plasma cutting, EDM, and grinding processes. In this blog post, we go over the 5 key ways to make your fume extraction system work better so that you can know how you can improve the fume extraction system’s performance.

Enhancing your fume extraction system's functionality is crucial for the following reasons:

The following are benefits of performing fume extraction systems in your factory:
  • The air in your factory will remain clean and healthy.
  • Protection of Employee Health
  • Improvement in overall productivity on the shop floor
  • An improvement in the company's goodwill

Many progressive organizations make large investments in establishing fume extraction systems because of these advantages. However, it is discovered that the manufacturing environment is still contaminated in numerous locations despite the presence of fume extraction equipment.

But—hold on?

If, despite owning a fume extraction system, you do not experience the aforementioned advantages, you should reconsider and look into the following problems to determine the true cause. Filter ON is eager to assist you and offer answers when required. The primary cause is these systems' less-than-ideal performance. The following are some of the most frequent problems encountered:

5 Key Issues That Are Deteriorating the Performance of the Fume Extraction System:

If your mist collector is based on ESP technology, then you need to follow these maintenance tips:

Frequent breakdowns of fume extraction systems are due to overload of filters or overload of electric motors. Overload in filters may take place due to improper cleaning of filters, not maintaining the preventive maintenance schedules, or incorrect filter selection.

Frequent overload of the motor takes place due to improper blower-motor selection, faulty overload setting, or filter choke.

Due to frequent breakdowns in fume extractors, it is not able to extract and filter the fumes consistently, which leads to fumes escaping the shop and resulting in a polluted work environment.

Many times, imported machine tools come fitted with fume extractors and mist collectors. However, the spares of such imported fume extractors are found to be extremely costly with long lead times. Thus, the replacement is delayed by management, causing suboptimal performance or breakdowns of such imported fume extractors.

Certain components of the fume extraction system must be changed periodically. For example, if your system has cartridge filtration, you should replace it when it starts to get dirty and exhibit issues with fume capture.

One of the challenges, especially with imported fume extractors as well as some domestic manufacturers, is that the after-sale service for the equipment is not available, due to which such equipment remains in breakdown or has to be scrapped before the useful life is over.

For the fume extraction system to operate at its peak efficiency, these problems must be resolved.

Programmed Maintenance:

In order to ensure the maximum efficiency of the air filter, it is necessary to undertake preventive programmed maintenance at regular intervals.

Filter, Seals, and Rotors Maintenance:

Cleaning the filters:

Careful and regular cleaning of all the internal parts (shell, drainage pipe, drainage ring, etc.) ensures high performance and long life of the air filter.

It is also important to routinely inspect the inside of the centrifuge and the turbine blades to remove any potential deposits of metal fragments, sludge, or other debris that might lead to a loss of balance in either the centrifuge or the turbine. to get rid of any potential deposits of sludge, metal particles, or other debris that might throw the centrifuge or turbine out of balance.

For the internal cleaning of the air filter and the rotators (either turbine or centrifuge), use a clean brush saturated in a mild industrial detergent solution. Alternatively, standard liquid soaps can be used. Should the dirt be very resistant, it is advisable to remove the rotor, use an alternative cleaning solution, and allow the centrifugal device to dry in the open air or dry with a jet of compressed air.

Structural Checks Required Yearly:

Each year:

Verify that the anti-vibration joints' nuts are securely tightened.

Every year:

Check the condition of the safety tie rods.
Check the good condition of the mist collector shell.

Every 4 years:

Replace the anti-vibration joints.

Benefits of Routine Maintenance of Oil Mist Collector Systems:

Analyzing Total Ownership Costs: Selecting the Right Clean Air Project Option

Analyzing Total Ownership Costs: Selecting the Right Clean Air Project Option

In the previous couple of blogs, we discussed planning and designing clean air systems, including choosing the right filtration technology and fan selection. Total ownership cost is a crucial parameter to consider, including filter technology, air flow capacity, running costs, filter replacement costs, blower capacity, and ducting length.

What is the total ownership cost?

Total ownership coat, a management accounting concept, helps determine the direct and indirect costs of a product or service over the long term to arrive at the correct decision while making decisions.

What is the total ownership cost of a clean-air system?

Total ownership cost for a clean air system consists of some parameters such as air flow capacity, filter efficiency, compliance with EMS, size of equipment, considered duct length, static pressure, blower capacity, cell configuration, total initial investment cost, running cost for 1 year, AMC charges per year, standby filter cell, replacement cost of the filter, any optional accessories, etc.

In short:

Total Ownership Cost concept for 3-5 years (installation cost + running cost + maintenance cost + replacement cost = Total Ownership Cost)

Consider a simple case study to illustrate this concept. A fume extraction system with a 45,000 CMH airflow capacity—three options based on different filtration technologies—is worked out.

You can read about the above 3 technologies in our previous blog article <a href="https://filter-on.com/2024/04/05/selecting-the-right-filtration-technology/" style a:link, a:visited { background-color: #f44336; color: white; padding: 15px 25px; text-align: center; text-decoration: none; display: inline-block; } a:hover, a:active { background-color: red; } here.

Fig: Total ownership cost(Technology wise breakup)

Understandings from the above example:

As per the above example of total ownership cost calculation about the 3 technologies, we can conclude that the ESP technology is totally beneficial in the long run as per the costing, as the total cost is very low; it’s only 154.56 lakh as compared to cartridge technologies 215.94 lakh and wet scrubbers 310.96 lakh for the period of 3 years.

Key takeaways from the above example:

  1. From the above example, you can see that the total cost of ownership of ESP technology is low as compared to the other two technologies.
  2. The total cost of ownership consists of several parameters that are very important, including air flow, blower capacity, initial cost, filter cost, cost of ducting, etc.
  3. The most important parameter of the clean air system is air flow calculation, so air flow rate is the most comparable factor to check which proposal is capable of solving your industrial indoor pollution problem.
