   Carbon Monoxide (CO)

   Carbon monoxide (chemical abbreviation: CO) is a clear, colourless gas you can’t smell or taste.
   It’s the product of incomplete combustion of materials containing carbon, such as fossil fuels.

   Sources of CO in construction are
    u engine exhaust (this is the most common source)           Engines on
    u fuel-fired heating devices.                                   and

   ® death.                             poisoning

     Never work alone in an area where carbon monoxide can accumulate.
     Make sure the area is well-ventilated. Keep doors and windows open. If necessary, use fans to
      bring in fresh air.
     Monitor carbon monoxide levels. You need a gas detector to do this.
     When necessary use exhaust hoses or fans to draw engine exhaust out of the work area.
     Choose an indirect-fired heater instead of a direct-fired heater when you want to heat an
      enclosed space. An indirect-fired heater vents combustion by-products outdoors while ducting
      heated air indoors (see image above). A direct-fired heater (such as an open-flame or closed-
      flame heater) releases combustion by-products into the heated area.
     Have a written policy for controlling and monitoring CO in your health and safety program.
