quarters
–
Use of direct-fired heaters in the construction
environment can result in exposure to levels of
CO, CO₂, and NO₂ considered to be hazardous
to health and potentially life threatening
–
Do not use in unventilated areas
–
Know the signs of CO and CO₂ poisoning
• Headaches, stinging eyes
• Dizziness, disorientation
• Difficulty breathing, feels of being
suffocated
–
Proper ventilation air exchange (OSHA 29
CFR 1926.57) to support combustions and

–
Periodically monitor levels of CO, CO₂ and
NO₂ existing at the construction site – at the
minimum at the start of the shift and after 4
hours.
–
Provide ventilation air exchange, either
natural or mechanical, as required to maintain
acceptable indoor air quality
–
Ensure that the flow of combustion and
ventilation air exchanges cannot become
