Although the transportation of hazardous materials is regulated, accidents can occur if there is a spill, a leak or an explosion.

Depending on the situation, the authorities may ask you to:

  • comply with a shelter-in-place order or an evacuation order
  • respect a security perimeter
  • refrain from drinking water or eating certain foods
  • clean your home or belongings
  • be alert to the appearance of certain physical symptoms

Follow your municipality and Urgence Québec social media feeds and consult local media outlets for information about the current situation and steps to be taken.

What to do after

If the authorities allow it and there is no risk to your safety, you can go home. It's best to go during the day, when problems and hazards are easier to see.

When you arrive, take pictures or videos to document the damage to your home and notify your insurer.

Verify if your water is potable, that is, if it is safe to drink. If the colour, odour or taste of your drinking water is questionable, contact the municipal authorities before consuming any.

If the power has been off more than six hours, check the quality of food before eating it. Throw out any food that shows signs of deterioration. Consult Power outage and your food This hyperlink will open in a new window. (French only) for information on deciding what to keep and what to throw out from your refrigerator and freezer.

For the same reason, do not take any medications that must be stored in a cool place but were not. Return them to the pharmacy.

Pay attention to stress reactions after a disaster:

  • Anxiety
  • Apathy or loss of energy
  • Aggressiveness
  • Increased alcohol or drug use

Appropriate psychological guidance can help you cope with responsibilities stemming from the situation. Contact Info-Santé at 811 and select Info-Social to speak with a social worker. This confidential service is available 24 hours a day, 7 days a week.
