Engine exhaust contains gases that are considered hazardous to your health. These gases are created by Internal Combustion Engines:

  • Gases (e.g. carbonmonoxide, nitrogen, carbon dioxide)
  • Vapor (e.g. what happens to gas and fuel liquids which change physical state) 
  • Soot (e.g. engine exhaust - particles small enough to be suspended in air)

The maximum allowable concentration of exhaust in the work place environment is regulated and evaluated on a (MAK) scale.
