5 Gas Detection Principles & Applications Occupational Health and Safety Code 2009 Part 26 Ventilation Systems Application 386 This Part applies to work sites if a mechanical ventilation system controls worker exposure to (a) an airborne contaminant that exceeds or is likely to exceed the occupational exposure limits prescribed in this Code, (b) a biological contaminant that exceeds or is likely to exceed the occupational exposure limits prescribed in this Code, (c) potentially hazardous dust, fumes, gas, mist, aerosol, smoke, vapour or other particulate of a kind or quantity that is given off by a process, (d) an atmosphere that has flammable levels of gases, vapours, liquids or solids, or (e) an atmosphere that has less than 19.5 percent or more than 23 percent by volume of oxygen. Safety 388(1) An employer must ensure that provision is made to warn workers immediately if a ventilation system fails, and to provide for their protection. Codes, Standards and Drivers National Building Code of Canada 2005 Division B Acceptable Solutions Ventilation of Storage Garages 1) Except as provided in Sentences (4) and (6), an enclosed storage garage shall have a mechanical ventilation system designed to a) Limit the concentration of carbon monoxide to not more than 100 parts per million parts of air, b) Limit the concentration of nitrogen dioxide to not more than 3 parts per million parts of air, where the majority of the vehicles stored are powered by diesel-fuelled engines, or c) Provide, during operating hours, a continuous supply of outdoor air at a rate of not less than 3.9 L/s for each square metre of floor area (see Article ). (See also Sentence (4).) 2) Mechanical ventilation systems provided in accordance with clause (1)(a) shall be controlled by carbon monoxide monitoring devices, and systems provided in accordance with Clause (1)(b) shall be controlled by nitrogen dioxide or other acceptable monitoring devices. (See Appendix A.) W.H.O. Classified NO2 to be as carcinogenic as asbestos

10 Gas Detection Principles & Applications Vehicle Maintenance Facilities / Garages Background Depending on the type of vehicle maintenance facility, gas hazards may be prevalent in several instances that include carbon monoxide, nitrogen dioxide, liquefied natural gas, and compressed natural gas. Situation/Problem Carbon Monoxide CO can reach dangerous levels when vehicles idle for a sustained period. Nitrogen Dioxide from diesel engine emissions. Liquefied & Compressed Natural Gas LNG/CNG is comprised of mostly pure methane gas, which is highly explosive.

16 Three main types of gas Hazard Symbols Flammability or explosive - % per volume (%vol) or % per LEL (%LEL) A relative property of the vapor of more or less stable compounds that ignite and burn to cause an explosion when combined with air. Toxicity - ppm (Parts Per Million) A relative property of more or less poisonous compounds that act as causative agents in harmful effects on humans. Deficient or enriched- % Oxygen (O 2 ) An atmosphere that contains low or high O 2 concentration levels.
