**4.3. Scenario 2: Fire truck incident**

This scenario develops the consequences of the fire on a truck loaded with pallets, we assume that the truck is loaded exclusively with generic aerosol or fertilizer.

Nitrate-based fertilizers (that do not contain high nitrate content) are not capable of detonation. The ammo-nitrates high or medium dosage, French standards or European are difficult to detonate in the absence of contamination. Furthermore, dust fertilizer containing ammonium nitrate in the air are not combustible and do not present an explosion risk, unlike the dust of grain or organic fuels.

The following scenario develops the consequences of a fire truck loaded with pallets at a unloading dock site. The fire or explosion of aerosols and fertilizer is due to inflammation of a palette (mechanical heating, inflammation, engine, non-compliance with the prohibition of smoking). We left the assumption that a cigarette would be has the origin of the starting point of fire. We leave the principles which another vehicle charged with manure would be been parked on the quay dimensioned. The starting point of fire and the propagation with the truck containing of manure cause effects missile, explosions, and dangerous heat fluxes for the man as well as the toxic dispersion of smoke, of projection has missile effect as well as discharge of water and product polluting for environment.

#### **4.4. Scenario 3: Hazardous liquid spill**

Accidental discharge is related to the presence of liquid products on site. The spill may trigger the leakage of an important quantity of hazardous liquid. A leakage of hazardous substances can occur due to the fall of one or more pallets of a rack but also due to a weakness in on (or a series) of container (bottle, can). A spill of hazardous substances can have an impact on the environment and on people.

In the same way, if the liquids contained are flammable liquids, they will support the fire. The generators of aerosols are thus the subject to specific storage, depending on the nature of the

The method used to assess the effects of an explosion of aerosols in a warehouse is multi-energy model. Explosion cloud formed by the gas contained in a bottle would not reach the thresholds of overpressure. Regardless of the distance to the cloud, a target suffers less than 20 mbar pressure which causes no human and material damage. We consider the explosion of the cloud formed by the simultaneous outbreak of 100 bottles of aerosols, which is extremely unlikely even when taking into account that the bottles are for most made on

Because of the loss of integrity of a container, a liquid will flow and form a pool of dangerous liquid which mainly function of the topography, the viscosity of the product and quantity.

The multitude of references and stored products do not enable to study exhaustively all dangerous chemical reactions. However, all possible precautions are taken to avoid storing incompatible products in a single cell.

This scenario occurred and may occur throughout the life of the installations and no person will be impacted. We will find a fall of pallet that will provoke liquid spill which is the starting point of fire, projection missiles effect, various explosions and propagation of smoked and gas dangerous for the man and the environment.

According to the nature of fire, it must there have a respect of the means of extinction, in this case of figure it will be impossible to respect this standard, and the means of extinction set up, will cause a pollution of the natural environment.
