Hazardous materials
What are the risks of toxic substances being released, or hazardous materials being spilled, in Montréal? What steps has Montréal taken to make sure the population is safe in the event of an accident? Find out how this kind of disaster is managed.
Risk of accident
When companies use toxic materials, Montréal works with them to put measures in place ensuring that residents are prepared for toxic leaks and will be notified quickly if they occur. If there is an accident inside a factory, a warning siren will immediately alert citizens to the danger. If this should occur, here are the safety instructions you should follow.
If there is a spill, a leak, a fire or an explosion while hazardous materials are being transported, responders will quickly be deployed to secure the area and tell the public what to do.
Factories and warning sirens
In Montréal, 9 factories have a warning siren for environmental emergencies. If a toxic substance is released, the siren tells the population to take shelter quickly. The sirens are connected to the Service de sécurité incendie de Montréal and to the 911 emergency call centre.

Siren test
Every year, Montréal works with the 9 factories to organize a siren test. This simulation exercise is designed to help people living near the factories understand how to protect themselves if there is an industrial accident. It is also a way of making sure that all equipment is working properly and that all emergency responders are in a state of readiness. Residents are notified in advance that the test will take place.
