(1) A ventilation system must not be obstructed by material or equipment placed in front of the ventilation air intakes or discharge points.
(2) Outdoor air intakes must be located so that outdoor air entering the ventilation system does not contain any contaminant in a concentration greater than normal outdoor ambient air in that locality.
4.77 Discharged air
A ventilation system that discharges air from the work area must be designed to minimize the likelihood of exposing any worker at a workplace, including an adjacent workplace
(a) to an air contaminant in a concentration which exceeds either 10% of its applicable exposure limit in Part 5 (Chemical Agents and Biological Agents), or an acceptable ambient air quality standard established by an authority having jurisdiction over environmental air standards, whichever is greater, and
(b) where practicable, to an objectionable odour.
4.78 Preventive maintenance
(1) To maintain acceptable air quality, the employer, or if the employer is not responsible for maintenance of the ventilation system, the owner of the ventilation system must establish an effective preventive maintenance program for the ventilation system.
(2) Preventive maintenance must include
(a) regular inspections
(i) of all critical components of the ventilation system, such as dampers, fans, belts, baffles, ductwork, diffusers and control systems, and
(ii) for conditions which would promote the growth of micro-organisms, such as water leaks or stagnant water pools,
(b) correction of any deficiencies found during the inspections carried out under paragraph (a),
(c) repair or replacement of malfunctioning and consumable components, such as filters and belts, and the cleaning of air distribution systems, ducts and dampers when necessary to correct an indoor air quality deficiency,
(d) adequate treatment of open water systems associated with ventilation equipment such as cooling towers and humidifiers, to control biological growth, and
(e) maintenance of combustion sources, such as furnaces, space heaters and water heaters to assure proper burning and exhausting of waste gases so that recirculation of gases to the workplace will not occur.
4.79 Investigation
(1) The employer must ensure that the indoor air quality is investigated when
(a) complaints are reported,
(b) occupancy in the space changes substantially, or
(c) renovations involving significant changes to the ventilation system occur.
(2) An air quality investigation must include
(a) assessment of the ventilation rate, unless the indoor carbon dioxide level is less than 650 ppm above ambient outdoor levels,
(b) inspection of the ventilation system as required in section 4.78(2),
(c) sampling for airborne contaminants suspected to be present in concentrations associated with the reported complaints, and
(d) a record of the complaint, the findings of the investigation, and any actions taken.
Note: In subsection (2)(a) carbon dioxide is considered a marker indicator of sufficient outdoor air, not as a toxic air contaminant for which the exposure limit established by would apply. Normally, ambient levels are approximately 350 ppm, but may be higher in locations such as urban areas or during weather conditions such as inversions. Ambient levels may be assumed to be 350 ppm unless sampling establishes otherwise.
4.80 Temperature and humidity
The employer must ensure that temperature and humidity levels within the indoor work environment are maintained within acceptable comfort ranges, as far as is practicable.
Note: Refer to the ASHRAE publication Handbook of Fundamentals or to the WorkSafeBC publication Indoor Air Quality [PDF 1.5 MB] for information on acceptable temperature and humidity levels.
Environmental Tobacco Smoke
4.81 Controlling exposure
The employer must control the exposure of workers at any workplace to environmental tobacco smoke by
(a) prohibiting smoking in the workplace,
(b) restricting smoking to a safe outdoor location that is a minimum of 3 metres from a doorway, window or air intake of an indoor workplace, subject to section 4.22 (3) of the Tobacco Control Regulation, B.C. Reg. 232/2007, and
(c) prohibiting working in an indoor area where smoking is allowed under section 4.23 (2) (a) or (b) of the Tobacco Control Regulation, except as permitted in section 4.82 of this regulation.
[Amended by B.C. Reg. 258/2008, effective January 1, 2009.]
4.82 Exceptions
(1) An employer must ensure that a worker does not work in an indoor area where smoking is permitted under section 4.23 (2) (a) or (b) of the Tobacco Control Regulation, B.C. Reg. 232/2007, unless
(a) the worker must enter the area to respond to an emergency endangering life, health or property,
(b) the worker must enter the area to investigate for illegal activity, or
(c) the tobacco smoke has been effectively removed.
(2) If necessary to prevent tobacco smoke from entering a workplace, a room where smoking is permitted under section 4.23 (2) (a) of the Tobacco Control Regulation, B.C. Reg. 232/2007, must be provided with a separate, non-recirculating exhaust ventilation system that
(a) is designed in accordance with expected occupancy rates,
(b) maintains adequate air flows from non-smoking to smoking areas,
(c) discharges directly to the outdoors, and
(d) meets all other requirements for a smoking lounge
specified in the American Society of Heating, Refrigerating and Air-conditioning Engineers Standard 62-1989, Ventilation for Acceptable Indoor Air Quality.

Occupational Environment Requirements
4.84 Eating areas
(1) Workers must not keep or consume food in an area of a workplace where it could become unwholesome because of workplace contaminants.
(2) The employer must ensure that an area suitable for the storage and consumption of food is provided for workers if
(a) there is a risk that food stored or consumed at a workplace may become unwholesome because of workplace contaminants, or
(b) food storage or consumption is restricted or prohibited at the workplace.
[Enacted by B.C. Reg. 421/2004, effective January 1, 2005.]
4.85 Washroom facilities
(1) Except as provided by subsection (2), the employer must ensure that a sufficient number of plumbed washroom facilities are readily available for workers.
(2) If plumbed washroom facilities cannot be provided because of the nature of the workplace or the nature of the work in which the worker is involved, the employer must
(a) provide access to portable washroom and hand-washing facilities, or
(b) make such other reasonable arrangements to accommodate workers as the circumstances allow, if access to portable washroom and hand-washing facilities cannot be provided.
(3) If washroom facilities are provided they must be
(a) maintained in proper working order,
