Part 26 Ventilation Systems

Section 388 Safety

Subsection 388(1) Warning workers

If a mechanical ventilation system fails, a method of immediately warning and protecting workers must be in place. The warning system can be as simple as streamers of tissue paper attached to a fume hood or as sophisticated as audible alarms and warning lights. Any effective system may be used as long as workers understand the warning.

Subsection 388(2) Training

Section 21 requires that if a worker may be exposed to a harmful substance at the work site, the employer must establish work procedures that minimize exposure and ensure that each worker affected is trained in the procedures, uses the training and is instructed regarding the health hazards associated with exposure to the substance.

As required by section 13 of the Occupational Health and Safety Regulation, if an employer develops work procedures, the employer must ensure that all workers affected are made familiar with the procedures before they start work. If workers are required to use safety equipment or personal protective equipment, the employer must ensure they are trained in the application, care, use, maintenance and limitations of that equipment.

Workers who use or depend on a ventilation system for their health and safety must be trained to operate it properly and the procedures to follow if the system malfunctions. Workers responsible for system maintenance need to be trained in its proper operation and the manufacturer-recommended maintenance procedures.
