Industrial Fumes Monitoring: Ensuring Compliance and Safety Standards 

09/05/2024by admin0Read: 6 minutes

Industrial fumes, generated by different manufacturing processes, can pose serious risks to environmental and human health. Efficient monitoring and management of these emissions is crucial for adhering to compliance and safety standards. In Australia, stringent regulations have been implemented to ensure that emissions from industrial activities do not cause harm to the environment and local communities.

This blog will discuss the importance of industrial fumes monitoring and outline the regulatory measures in place within Australia.

Why Monitor Industrial Fumes?

Monitoring industrial fumes is vital for several reasons:

1) Protecting the Environment: 

Emissions from industries can contribute to air pollution, which negatively impacts the atmosphere, ecosystems, and biodiversity.

2) Protecting Human Health: 

Exposure to harmful substances like particulate matter, sulphur dioxide, and nitrogen oxides can cause respiratory illnesses, cardiovascular diseases, and lung cancer.

3) Ensuring Compliance with Government Regulations: 

Strict monitoring helps industries maintain permits and stay within the acceptable emission levels outlined by governing bodies.

 4) Reducing Liability: 

Demonstrating compliance with regulatory limits helps protect businesses from lawsuits and fines.

Exposure Standards

An exposure standard is one that is specified in the Workplace Exposure Standards for Airborne Contaminants and designates the upper limit for the airborne concentration of a certain chemical or combination.

Three different exposure standards exist:

a) Time-weighted average (TWA) of 8 hours

b)  STEL, or short-term exposure limit.

c) Peak limitation

a) Time-weighted average (TWA) of 8 hours

The 8-hour time-weighted average exposure standard is the average airborne concentration of a drug allowed over the course of an eight-hour workday and a five-day workweek. It permits brief excursions over the exposure standard during times of continuous daily exposure, as long as they are offset by prolonged periods of exposure below the standard. Excursions over the 8-hour TWA exposure level should be kept under control.

b) Short-Term Exposure Limit (STEL)

The short-term exposure limit (STEL) is the maximum average airborne concentration of a drug allowed during a 15-minute period. STELs control only the short-term exposure limit, while the eight-hour TWA exposure guidelines benefit from STELs for cumulative consumption over extended periods of time.

STELs are often constructed to reduce the risk of:

  1. permanent tissue alteration.
  2. excessive irritability, and
  3. a level of narcosis that might lead to workplace accidents.

STELs should be used when there is evidence of negative health consequences, with a maximum exposure period of 15 minutes and 60 minutes between each subsequent exposure.

c) Peak Limitation

Peak limitation exposure requirements are defined as the greatest or peak airborne concentration of a certain chemical measured during the shortest analytically possible time period, no longer than 15 minutes. These chemicals have the potential to cause acute effects after brief exposure to high concentrations, and an exposure standard for peak restriction must never be exceeded.

Regulations Governing Industrial Fume Monitoring in Australia:

Australia has several federal and state-level regulations that oversee industrial fumes monitoring:

  1. The National Environment Protection Measures (NEPM): The NEPM for ambient air quality sets national standards for six key pollutants: carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter (PM10 & PM2.5), and sulphur dioxide.
  1. State-Based Legislation: Each state in Australia has its environmental protection laws governing the emission of pollutants from various sources, including industries.
  2. National Pollutant Inventory (NPI): Australian businesses must assess their emissions against NPI reporting thresholds annually – including sources of outdoor air pollution.

Methods of Industrial Fume Monitoring:

The different monitoring methods for industrial fume emissions are given below:

1) Personal Air Monitoring

The amount of airborne pollution in the workplace and the effectiveness of airborne pollutant management measures may both be determined via personal air monitoring.

An expert can do personal air monitoring, such as an occupational hygienist.

2) Continuous Emission Monitoring Systems (CEMS): 

To monitor the effluent gas streams produced by combustion in industrial operations, continuous emission monitoring systems (CEMS) are utilised. Oxygen, carbon monoxide, and carbon dioxide concentrations in flue gas may be measured using CEMS to give data for combustion control in industrial settings.

These systems measure emissions in real-time, allowing businesses to monitor compliance with emission limits and make operational adjustments when needed.

3) Stack Emission Monitoring

Stack monitoring is the technique of keeping an eye on the emissions leaving the stacks to control the number of pollutants released into the atmosphere. Carbon monoxide (CO), methane gas (CH4), oxides of sulphur and nitrogen (SOx and NOx), as well as hydrocarbon compounds, are the main pollutants that stack release.

Quantifying the types and quantities of contaminants is necessary to:

  1. Analyse if existing or projected emission restrictions are being followed.
  2. Calculate the monetary losses brought on by product losses.
  3. Obtain engineering information to specify the control equipment’s design.
  4. Check the effectiveness of the installed control devices.
  5. provide the emission data needed for modelling.
  6. calibrate continuous monitoring devices.

4) Periodic Testing: 

This method involves physical sampling of emissions during specific periods, providing a snapshot of emissions. Sampling is done using standard test methods endorsed by regulators.

5) Predictive Emission Monitoring Systems (PEMS): 

These systems predict emissions based on process data such as temperature, flow rates, and pressure variations.

Compliance with Industrial Standards

For efficient industrial fumes monitoring, compliance with industrial standards, as stated by the regulations, is essential.

We have given below the standard procedure to comply with safety standards outlining the ‘Guidance on The Interpretation of Workplace Exposure Standards for Airborne Contaminants’

1) Air Monitoring Procedure

An effective air monitoring program requires training, specialist knowledge and a high level of competency and experience. It is important to understand the nature of contaminant concentrations in the workplace, the statistics relevant to their measurement and the interpretation of measurement results. If a consultant is engaged to assess compliance with an exposure standard or the effectiveness of hazard controls, it is recommended to ask to see evidence of their qualifications, experience, and competence.

Sampling can be carried out by another competent person, under the supervision of an occupational hygienist. Air monitoring should be arranged on a day when normal processing activities are taking place. It can take longer if a variety of work processes need examining and laboratory analyses are required.

2) Role of Consultant

The consultant will develop a plan for air monitoring and give recommendations for how many people should be deployed where and when. Measurements of exposure should be based on an impartial, representative sampling of real worker exposure.

Static samples should only be used to evaluate the efficacy of process hazard control measures, and fixed continuous monitoring can be used to provide early notice of leaks or other polluting sources. NATA-accredited laboratories should analyse samples collected at the worksite for re-accreditation.

3) Exposure Monitoring to Determining Compliance 

To ensure that exposure guidelines are being followed, exposure monitoring is required. To establish if compliance is being attained, professional judgement and counsel may be needed. Only an air monitoring programme that has been put into operation and involved several worker exposure measurements may be used to assess compliance. Negotiation with the regulator and employees on the scope of monitoring may be necessary if safety concerns have been raised or if an inspector has requested air monitoring.

4) Qualitative Tools and Methods for Estimating Exposure

Mathematical models can be used to estimate airborne contaminants in the workplace, but only an occupational hygienist or other appropriately certified individual should use them. IH Mod offers a number of mathematical models in Excel spreadsheets that can be used to determine chemical airborne concentrations.

5) Key Inclusions of the Air Monitoring Report

A detailed air monitoring report should include the following key information:

  1. History and goals of the air monitoring program, as well as other information.
  2. the process(es) reviewed, the work schedules, the personnel, and the dangers involved in the control measures used and how well they are working images and diagrams when needed.
  3. what measurements were made and how sampling was done?
  4. how and where samples were analysed.
  5. the method used.
  6. the test results, including the 8-hour time-weighted average concentrations calculated.
  7. an interpretation of the test results and comparisons with exposure standards.
  8. an opinion on compliance and what the results mean.
  9. an assessment of the risks to workers.
  10. advice on pertinent information.

6) Health Monitoring

The main method used to evaluate the working environment is often the assessment of the aerosol concentration of a specific pollutant and subsequent comparison with the applicable exposure standard(s). Health monitoring may also be necessary for some dangerous compounds to evaluate the hazards to employees who may be exposed.

All exposure pathways are included during health monitoring, including biological monitoring, rather than only exposure by inhalation of airborne toxins. The following materials, which are accessible from the Safe Work Australia website at www.swa.gov.au, provide guidance on health monitoring.

  1. Restricting access to locations where dust, gases, fumes, and vapours are emitted.
  2. employing engineering controls such as local exhaust ventilation and on-tool dust extraction.
  3. and wearing the proper personal protective equipment, particularly respiratory protection equipment.
