WARNING
AIR QUALITY HAZARD
– Do not use this heater for heating human living
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
maintain acceptable air quality shall be
provided in accordance with OSHA 29 CFR
Part 1926.154, ANSI A10.10 Safety Requirements

WHILE CONNECTED TO A POWER SOURCE
– 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
obstructed
– As the building "tightens up" during the
construction phase ventilation may need to be
increased
