MECHANICAL VENTILATION. (a) The premises must be ventilated in accordance with the Building Code of Australia and AS1668.1
MECHANICAL VENTILATION. Contractor is responsible for ensuring that the house meets BPI standards for fresh air ventilation.
MECHANICAL VENTILATION. In lieu of openable windows, doors, or other devices for natural ventilation, adequate ventilation may be a system of mechanical ventilation which provides not less than two (2) air changes per hour in all habitable rooms and/or bathrooms or toilet compartments. No mechanical exhaust system, exhausting vapors, gases or odors shall be discharged into an interior roof area, crawl space or cellar unless such interior roof area, crawl space, or cellar is adequately vented to the outside. Any kitchen or kitchenette lacking natural ventilation shall be equipped with a system of mechanical ventilation which provides at least two (2) air changes per hour in the room. The system shall exhaust and discharge directly to outside air.
MECHANICAL VENTILATION. The requirement for mechanical ventilation is to ensure that adequate air movement is achieved to reduce worker exposure to toxic metals to as low as feasible, and to enhance visibility. Design the system with proper exhaust ports or plenums, adequately sized ductwork, adequately sized discharge fans and air cleaning devices (dust collectors) and properly sized and distributed make-up air points. Natural ventilation does not require the use of mechanical equipment for moving dust and debris through the work area. It relies on natural air flow patterns, if any, through the containment.
