Major hazards
Major Risk Management Unit

Experience has shown that our region is exposed to major risks. In anticipation of these natural and technological risks, it is essential to organize if one had to limit the damage and facilitate the return to normal.

The 13 / 08 / 2004 Modernization of Civil Security Act states in its article 1 that "The aim of civil security is to prevent risks of all kinds, to inform and alert The protection of persons, property and the environment through the preparation and implementation of appropriate measures and means "

Very conscious of this need, the Collectivité has set up a risk management unit, represented today by Mrs PETRUS-FERGA Annick, Elected Officer and Mrs Charlotte TERRAC, Project Officer, in order to evolve the Territorial Plan of (PTS) and to formalize a suitable crisis organization. The purpose of this service is to consolidate, plan and harmonize all the documents of competence of the Collectivity and all the human and material resources contributing to the preventive information, the alert, the safeguarding, the protection and the Support of the population.

Territorial information on major risks

The management of a crisis situation depends as much on the preparation of the community as on the reaction of the inhabitants.

The DITRIM presents:
- the characteristics of known natural and technological hazards in the territory as well as information on the memory of past events;
- a list of the ordinances establishing the state of natural disaster;
- the informative maps of the Plan for the Prevention of Natural Hazards approved by Prefectoral Order No. 2011 / 009 on 10 February 2011;
- the arrangements for alerting and organizing safeguards and relief.

The booklet shows, for each risk, the preventive measures to take to reduce its vulnerability and the good behaviors or reactions to have in case of danger or alert.

Responsibility for the development of the PPRN rests with the Prefect.
The PPRN of the Community of Saint Martin was approved by prefectoral decree n ° 2011 / 009 the 10 February 2011.
The PPRN is a servitude of public utility.
The existence of natural hazards may justify prohibiting or imposing conditions on buildings.

The PPRN of Saint-Martin can be consulted on the site of the Prefecture or via the following link:

At the end of the articles L. 125-5 and R 125-23 to 27 of the Environmental Code, purchasers or tenants of real estate of any kind must be informed by the seller or the lessor, Whether or not it is a real estate professional, of the existence of the risks to which the property is exposed.
The state of the risks is compulsory in any real estate transaction appended to any type of written lease, reservation of a property in the future state of completion, promise of sale or act realizing or Noting the sale of real estate, whether built or not.

Natural hazards

It is in the West Indies that the seismic hazard is highest, being located at the subduction zone of the North American and South American plates under the Caribbean plate.
The magnitude measures the energy released by an earthquake and allows to evaluate its power. The power of an earthquake is also characterized by the length of the fault that comes into play. The more an earthquake releases energy and the more the fault yields over a long distance, the higher the magnitude.
The intensity measures the effects and damage of the earthquake in a given place: effects observed or felt by man.
An earthquake of very high magnitude can have a zero intensity when it takes place very far from any habitation.
The earthquake itself does not kill, it is the collapse of buildings, badly designed or poorly constructed, which can be accompanied by victims. The best prevention against this risk is therefore to build seismic.

Each year, prior to the start of the hurricane season, the Collectivité and the Prefecture organize preparatory meetings with all the services and actors concerned, in order to remind everyone of the different phases of the alert and to make an inventory of the means Implemented in the event of a major event.
Informed and sensitized by the media, the population applies the instructions of preparation and protection in case of threat or confirmation of threat (verification of material and alimentary reserves, preparation and protection of the home, withdrawal or stowage of any object that can transform into projectile).

Prevention and rescue booklet

A flood is a submersion, fast or slow, of an area usually out of water. Flooding is not unknown in some areas of Saint Martin.
The hydrographic network in our region is essentially composed of gullies that flow only during heavy rainfall, when the soils are saturated with water. Soil waterproofing (urban development) limits precipitation infiltration and increases runoff. In any urbanized area, the danger is to be carried away, isolated or drowned. Collective measures (maintenance and works) and individual measures (adaptation of constructions), taken and recommended, allow the considerable reduction of the damage caused by the floods.

Prevention and rescue booklet

Induced effects of earthquakes or high saturation of soils into water, land movements can be manifested by landslides, collapses or falls of rock blocks. The objective of reducing the hazard intensity (risk protection work) and therefore the vulnerability of the stakes (human and material), but in the In the case of large-scale movements, evacuation measures should be taken for your safety.

Tsunamis are a series of very long waves whose origin is most often the result of an earthquake, a volcanic eruption or a submarine landslide.
Our region can know 2 types of tsunamis: local, which can strike our coasts in a few minutes, and of distant or regional origin, which can touch us between a few tens of minutes and several hours, according to the remoteness of the source.
If the ground moves strongly and long under your feet, if you notice a sudden rise or fall of water or in case of alert by the authorities, a single slogan: go quickly to the heights!

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.

Prevention and rescue booklet

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 ...
