VENTILATION REQUIREMENTS
WHEN OPERATING HEAT TOOL
WARNING: During operation, the heat tool consumes propane and air
and produces carbon dioxide, carbon monoxide (CO), and water vapor.
Prolonged exposure to Carbon Monoxide is lethal and adequate ventilation
must be provided if the heat tool is to be operated indoors.
• To maintain a safe CO concentration (50 parts per million as set by OSHA
Standard 1910.1000 – Air Contaminants), ventilation requirements are 2,000
cu. ft. /min. of fresh air while the heat tool is operated at a maximum operating
pressure of 30 PSI.
• Based on a 1 1/2 minute heating cycle per pallet, the fresh air requirements are
3000 cu. ft. /pallet. Example: If the production rate is 10 pallets per hour, a
ventilation system needs to provide 500 cu. ft. /minute.
• In areas where ventilation is provided by open doors or windows, a safe level of
CO will be maintained as long as the room temperature does not rise above 150°F.
