Artificial Smokes and Fogs

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 during filming/performing. Our bulletin contains the following information:

  • Chemical Product Guidelines and Exposure Limits
  • Production Requirements
  • Joint Health & Safety Committee Responsibilities
  • Measuring Airborne Concentrations
  • Control Measures
  • Respirator Use
  • Additional Training
  • Regulation References
  • A handy single-page call-sheet memo
