Supporting Alberta OHS requirements
This work helps building owners and employers support their responsibilities under the applicable Alberta Occupational Health and Safety Code requirements, including Part 4, sections 16, 21 and 22, and Part 26, sections 386 and 387.
These provisions address worker exposure to harmful substances, assessment and control of potential exposure, airborne-concentration measurement where overexposure may occur, and the proper design, maintenance and operation of ventilation and make-up air systems.
