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 combustion and maintain
acceptable air quality shall be provided in accordance with OSHA 29 CFR Part 1926.154, ANSI
A10.10 Safety Requirements for Temporary and Portable Space Heating Devices and Equipment
used in the Construction Industry or the Natural Gas and Propane Installation Codes CSA B149.1
▫▫ 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.
