Phenomenon

Transportation of dangerous materials

Dangerous materials are divided into nine categories according to the type of risk they pose to public safety.

Risks in Montreal

Accident routier impliquant des matières dangereuses sur l'autoroute 40 à montréal - Crédit : Éliot AlbertA number of major roadways and railways run across the island of Montreal, including heavily populated areas. A large quantity of dangerous cargo travels along these roads and railways. Pipelines transporting gas and petroleum are also present in Montreal. Transportation of dangerous goods by ship along the St. Lawrence River is also a risk. The two possible causes of a marine spill are a ship travelling along the river or a broken pipeline under the river. The accidents that are the most likely to happen are those involving hydrocarbons.

However, main road interchanges, railway yards and ports are the most likely sites for this type of accident.
