Technological risks


The major industrial risk is the accidental hazard that can occur on industrial sites and can have serious consequences for people, property and the environment.

There are several types of effects, immediate or delayed, resulting from a possible industrial accident:
Thermal effects, As a result of a fire or explosion,
The effects of overpressure, Consecutive to an explosion or a burst,
Toxic effects Consequential to a dispersion in air of volatile toxic product or to a fire emitting toxic fumes,
Pollution effects, Generally resulting from the application or leakage of an environmentally toxic product to soil or water.

A hazardous good is a substance or object which by its physico-chemical (toxicity, reactivity ...) and physiological characteristics may present risks to man, property and / or the environment.
These goods may be transported in liquid (eg hydrocarbon) or solid (eg explosives) form. These substances often have higher concentration and aggressiveness than domestic ones.

The main consequences of the occurrence of an accident when transporting dangerous goods are:
- a fire
- a release of toxic cloud
- an explosion
- corrosion
- soil and / or water pollution


The risks generated by the transport of hazardous materials are difficult to understand precisely because, by definition, it is a circulating activity that is difficult to identify, locate and quantify. This risk is considered to be diffuse because it is scattered throughout the country.
The transport of dangerous goods by road is the mode of transport most exposed to accidents. The causes are various: lack of driving of the driver or a third party, poor condition of the vehicle, bad road conditions, unfavorable weather ...
