Sometimes an accident may cause a hazardous material to enter the air. Unless the hazardous material is flammable, emergency response professionals recommend that you stay indoors until you receive instructions to leave. Once you are inside, there are several things you can do to help your building protect you.
Our well weather-stripped buildings slow the movement of air into the buildings and any hazardous material that does enter is weakened when it mixes with the indoor air. It is imperative that you stay indoors, especially if you see a cloud, vapour, or smoke from the hazardous material outdoors or you can smell it indoors. You will be safer inside.
