Ventilation Equipment

Forced Air Ventilation is the primary engineering control used to maintain safe atmospheric conditions in confined spaces. The confined space should be ventilated using the following guidelines:

1. Locate the blower a safe distance from the confined space;
2. Ensure that the air supply is not contaminated;
3. If ventilation equipment blocks or restricts access to the confined space, precautions must be taken to provide entrants with respirable air for the time necessary to exit the space (Note: Using a saddle vent is a good way to avoid this problem altogether.) ;
4. If a flammable atmosphere exists or may develop, the ventilating equipment must be properly bonded and grounded to prevent a static discharge;
5. Continuous ventilation should be maintained for the duration of the entry; and,
6. When ventilating to eliminate a hazardous atmosphere, the blower should be run for a sufficient length of time. The atmosphere should then be re-tested to determine if conditions are safe for entry.
