Occupational asthma is a serious and preventable condition caused by exposure to airborne substances in the workplace—such as chemicals, fumes, dust, and hazardous materials. Over time, these exposures can lead to chronic respiratory problems, affecting both workers’ health and business productivity.
At A-Mac Environmental, we help organisations tackle this risk with expertly designed Local Exhaust Ventilation (LEV) systems.
What Is Occupational Asthma?
Occupational asthma is a type of asthma directly caused by breathing in harmful substances while at work. These include:
Isocyanates (in paints, varnishes, foams)
Flour dust (in bakeries)
Wood dust (in carpentry)
Welding fumes
Cleaning agents and solvents
Laboratory chemicals
Exposure to these substances can cause symptoms like wheezing, shortness of breath, coughing, and chest tightness. Left unmanaged, the condition can become permanent.
Who’s at Risk?
Workers across many sectors are vulnerable, including:
Without proper controls in place, daily exposure can cause long-term damage.
How LEV Helps Protect Your Workforce
LEV (Local Exhaust Ventilation) systems are one of the most effective ways to control hazardous substances in the air. Here’s how they work:
Capture contaminants at the source before they can be inhaled.
Remove harmful dust, fumes, vapours, and mists from the air.
Protect all workers in the area, not just the operator.
Support COSHH compliance and reduce liability.
Improve indoor air quality, promoting health and productivity.
Legal Obligations and Best Practices
Employers have a legal duty under COSHH (Control of Substances Hazardous to Health) regulations to assess and control exposure to harmful substances.
LEV plays a central role in compliance. Employers must ensure:
LEV systems are correctly designed and installed.
Thorough inspection and testing at least every 14 months.
Staff are trained on proper use and maintenance.
All servicing and inspections are documented.
