Diesel Exhaust

DID YOU KNOW?

In the U.S., particulate matter from diesel exhaust contributes to more than 21,000 premature deaths annually. [2] Diesel engines power our trucks, generators, and equipment — but their emissions are far from harmless.

KNOW THE RISK

  • Diesel exhaust is made up of two main components: gas and soot. The gas portion contains carbon monoxide, carbon dioxide, and nitrogen oxides. The soot includes fine particles made of carbon, organic materials, and trace metals. [1]
  • The soot is especially hazardous. These microscopic particles can penetrate deep into the lungs and bloodstream, where they contribute to inflammation, cancer, and cardiovascular disease. [1]
  • Health concerns extend beyond cancer — diesel exhaust is linked to asthma, bronchitis, heart disease, and reduced lung function. [1]

MITIGATE THE RISK

1. Never Tamper with Emissions Systems

  • Do not modify or disable diesel particulate filters or emission control devices. These systems are essential for reducing harmful emissions at the source.

2. Reduce Unnecessary Idling

  • Limit idling time to save fuel and reduce exposure to diesel particulates, especially in enclosed or heavily trafficked areas. [2]

3. Ventilate Workspaces

  • Ensure proper exhaust ventilation in garages, loading docks, and shops where diesel equipment is used. Prevent buildup of fumes by using fans and open-air systems.

DIESEL SAFETY REMINDER

You can’t always see what you’re breathing — but the effects are real. Take diesel exhaust seriously by maintaining equipment, reducing exposure, and ensuring clean air at work and home.
