Air Quality

These guidelines are recommendations to either eliminate or reduce worker exposure to inhalation hazards created by chemicals generated when using artificial smoke or fog (theatrical haze, fogs, mists, etc.). Artificial smoke or fog is commonly generated using a fog or haze machine, which releases a chemical solution as an airborne aerosol to create various effects […]

When choosing a filming or recording location, the producer must determine whether there are health risks for the members of the production crew and make the necessary corrections when the air quality does not meet the standards in WorkSafeBC OHS Regulation Part 4.7 Indoor Air Quality and Part 5 Chemical and Biological Agents. Artificially Created […]

As a reminder, the following information was disseminated to the Industry in 1974: Internal combustion engine driven equipment shall be operated inside of buildings or enclosed structures only when such operation does not result in harmful exposure to concentrations of dangerous gas or fumes in excess of threshold limit values. If concentrations exceed the limit […]

This safety bulletin covers substances that may and may not be used in generating artificially created smokes, fogs and lighting effects on production stages/sets. Artificially created smokes, fogs and lighting effect performing arts bulletin PDF

Kay Teschke, Yat Chow, Michael Brauer, Chris van Netten, Sunil Varughese, Susan Kennedy. March 2003. UBC’s School of Occupational and Environmental Hygiene have published this full report on the safety of atmospheric theatrical smokes and fogs in 2003. WCB’s 8-hour Exposure Limit (EL) for mists of mildly refined oils is 0.2mg/m3, and of severely refined […]

This report was submitted to IATSE by Aura Health & Safety Corporation in April 2018. With the increased use of fog-based products in the entertainment industry, interest in the health effects of fog exposures among workers in the industry has also grown. The International Alliance of Theatrical Stage Employees (IATSE) requested Aura Health and Safety […]

This bulletin discusses the hazards of carbon monoxide exposure during film shoots and how to manage the risks. It outlines what employers must do in planning shoots and training workers and supervisors, as well as maintaining equipment, conducting assessments, and implementing controls. It also outlines the need to coordinate work activities and support the joint […]

THEATRICAL SMOKE AND HAZE REGULATIONS Below are links to the American Actor Equity’s webpage that focuses on smoke and haze regulations for the motion picture and performing arts industries. The page includes: calibration factors, studies, a fillable report and more. Explore the PDFs below: Calibration Factors (PDF – 91 kB)  Time and Distance Guidelines (PDF […]

In the absence of other information, theatre-specific monitoring would be required to evaluate whether smoke/fog/haze machines are being used in accordance with the peak exposure guidelines. ENVIRON developed Time-and-Distance (T&D) Guidelines as an alternative to conducting theater- and production-specific monitoring. These T&D Guidelines were developed under conservative use assumptions (e.g., no on-stage activities or props […]
