Toxic fumes can infiltrate into or through a building from various sources—improperly stored chemicals, faulty refrigeration, equipment fires, gasoline engines operated near air intakes, etc.
If the presence of toxic fumes is suspected, the area or areas affected should be evacuated. Use a telephone away from this area and always call CMU Police (911) if it is an emergency, or 6547 if it is not an emergency.
Ventilate the contaminated area(s)
It may be possible to clear an affected area by opening windows and/or activating exhaust fans, provided such action is undertaken by trained personnel.
