Hazardous Materials Incident

Hazardous materials can be a health risk if they're inhaled, ingested or come into contact with skin depending on the type of material.

In all cases consider the following:

  • Time: minimize exposure to a hazardous substance
  • Distance: remain as far away as possible
  • Shielding: protect yourself from the substance

Enclosed affected areas

If you're in an enclosed affected area:

  • Immediately contact emergency services
  • Leave the area if possible, unless advised otherwise
  • Cover exposed skin and protect your airways, such as using a damp cloth, and minimize contact with the substance
  • Turn off or move away from air conditioning or heating vents
  • If you experience symptoms of exposure to hazardous substances, such as dizziness, perspiration, vomiting, change in breathing, heart rate or skin tone, seek immediate medical attention
  • You're reminded to ensure your own safety as the danger may still be present without any visible or odor signs

Open affected areas

If you're in an open affected area:

  • Follow the same steps for an enclosed area
  • Move away from the release site as quickly as possible


If you're in a vehicle:

  • Keep vehicle vents and windows closed
  • Don't use vehicle heating or air conditioning
  • Monitor radio and online media, and follow instructions from emergency officials
  • Drive away from the site if possible
