Effective July 1, 2019, amendments to various provisions of Regulation 851 (Industrial Establishments) have been approved that will help modernize workplace health and safety requirements. They will increase flexibility by:

  • Allowing the use of alternative procedures if worker health and safety is at least as well protected
  • Allowing workers to wear personal flotation devices instead of lifejackets when appropriate
  • Allowing the use of antidotes, flushing fluids or washes instead of eyewash fountains or emergency showers, where appropriate, to prevent permanent injury to the eyes or skin

In addition, amendments have been made to other OHSA regulations and will also come into effect on July 1, 2019, including:

  • Construction Projects (O. Reg. 213/91)
  • Occupational Health and Safety Awareness and Training (O. Reg. 297/13)
  • Mines and Mining Plants (Regulation 854)
  • Oil and Gas – Offshore (Regulation 855)

Amendments to Regulation 833 (Control of Exposure to Biological or Chemical Agents) and O. Reg. 490/09 (Designated Substances) will come into force on January 1, 2020 to provide workplaces additional time to comply with the amendments.
