AbstractPositive pressure ventilation (PPV) is achieved by placing fans outside a building and blowing air into the structure. When appropriate openings or vents are used in the structure, the airflow produced by the fan exhausts contaminants to the outside. Some U.S. fire departments have used PPV as a means to ventilate contaminated atmospheres after initial knockdown and extinguishment of a fire. In Ontario, the use of positive pressure ventilation is still relatively new. However, its use as a tool to improve conditions is being explored by a number of fire departments, including the Ottawa Fire Department. PPV procedures have been implemented by some Ontario fire departments on a limited basis. This includes tactics for its use in the fire attack mode as well as for ventilating contaminated atmospheres during salvage and overhaul operations.
