3. Why does Chemical Emergency occur?

The hazardous chemicals present in communities around the world are mainly in industrial facilities and in transit via highways, rail and waterways. If not properly used, they can endanger our health and poison our environment. Accidents (including fires, explosions and leakages) resulting in the release of these substances can have adverse effects on human health, property and the environment. Human exposure to hazardous substances can cause injury or even death for a large number of people.
