MSHA warns of health hazards stemming from diesel exhaust

Arlington, VA — Prolonged exposure to diesel particulate matter can increase the risk of cardiovascular, cardiopulmonary and respiratory disease, including lung cancer, the Mine Safety and Health Administration is warning.

According to a recent health alert from MSHA, diesel particulate matter is found in diesel exhaust and includes soot particles predominantly made up of carbon, ash, metallic abrasion particles, sulfates and silicates. 

In addition, short-term exposure to high concentrations of DPM may cause headaches; dizziness; and irritation of the eyes, nose and throat.

MSHA recommends using engineering and administrative controls from the Hierarchy of Controls to limit exposure. Control measures include:

• Installing cleaner-burning engines.
• Performing routine preventive maintenance of diesel engines to minimize emissions.
• Using special fuels or fuel additives (example: biodiesel).
• Increasing ventilation where diesel engines operate.
• Providing equipment cabs with filtered air.
• Restricting the amount of diesel-powered equipment and total engine horsepower operating in an area.
• Making sure the number of vehicles operating in an area doesn’t exceed ventilation capacity.
• Restricting unnecessary engine idling.
