Montrealers to get blasted by toxic alert sirens this afternoon

Montrealers will get blasted this afternoon when sirens echo across the city from nine factories.

It's a noisy test of the system which would be used to alert the population in case of a major industrial accident.

The sirens will be tested for three minutes at each of the factories, beginning at 2 p.m. ET.

The city says in a release the exercise will ensure the sirens are operating properly.

It will also be a chance to check the level of preparedness of all teams involved in emergency measures.

If a toxic leak were to occur, the sirens would serve as notice for people who are outdoors to quickly head to the nearest building, close all doors, windows and the ventilation.
