Designation, one calls danger property accident, also as dangerous material accident any kind of damage event, with which products (the danger property) of industry and such a thing inadvertently and in such quantities and/or under such circumstances arrive into the environment, which are harmful for humans, animals, environment or real values or can be (case of loss). As well-known example for instance the release of gasoline is to be called after a tanker accident.

Most chemistry accidents are danger property goods, since many chemicals fall under the danger property regulation.

Problem of a danger property accident

In accidents with danger property also a special endangerment for the task forces accompanies apart from the danger for the population and the environment. Depending upon material can be this fire and danger of explosion and/or the danger for life and limb (e.g. poisoning,

Since not all materials are held back by the normal employment clothes, often are necessary for the sealing and salvage. These have the larger fire-brigades, whatever danger-property-in-corrode particularly on are trained for costing and maintenance reasons only.

Even smallest quantities of certain materials (e.g. Chlorine compounds), bring a very large expenditure with itself to save it surely and afterwards properly dispose, above all if the accident in one occurred closed area. Besides perhaps not only a decontamination directly with the material into contact come of the persons and articles is necessary, but also the whole environment. Sometimes also soil and building parts must be removed and be disposed after a treatment in a special dump.

Further it is to be noted that two different materials, which are taken harmless for itself alone can cause completely different dimension of the endangerment, if they react to that. Like that water is not applicable as deletion and cooling agents with all materials, since it would cause an additional reaction. These materials are identifiable by the X in the upper line of the danger board.

Important sources of information for the task forces are the ERI Cards and the TUIS information system of the chemical industry.

Follow a danger property accident

As variously as the materials, which can be taken part, are also the consequences; here some examples are to point out, what can happen, if dangerous substances arrive uncontrolled into the environment.

Sandoz (Swiss-resounds) Basel

With the deletion of the storage hall of the Sandoz AG on 1 November 1986 with chemicals contaminated fire fighting waters inexplicably there a large fishing inheriting flowed into the Rhine and released. The reason for this were insufficient support possibilities for fire fighting waters.

Eisenbahnunfall of bath of mouths

With the head-on collision of two goods trains in September 2002 it came to the release of epichlorohydrin. During the investigation of the task forces after the accident with each sixth increased liver values were determined. As a cause insufficient protection equipment was determined.

Who renders help in danger property

A danger property accident requires the intervention of professional assistance organizations, which are particularly equipped for the fight of the effects of danger property goods in all rule. These are for example depending upon region:

1. the fire-brigades
2. the environmental protection authority, the environmental office or a comparable institution
3. the technical welfare organization (in Germany)
4. Units of the disaster control.

Which kind is the help who can be

The task of such institutions after a danger property accident consists with priority of it,

1. directly endangered persons to save and indirectly endangered persons in security to bring,
2. to secure the accident scene and to mark/lock the damage area off,
3. to identify the kind of the danger property,
4. to introduce and expert accomplish considering of the self-protection and the proportionateness the means suitable measures for the containment/delimitation and fight of the damage,
5. Corpses to save real values and animal wastes,
6. after possibility preventing measures with the goal into the ways lead that an appropriate incident does not repeat itself.

Above list indicates those succession of the measures potenziell which can be selected and stresses neither universal validity nor compelling completeness. Deviations are accordingly at any time possible for the responsible employment leader of the individual situation. The most important measures in danger property goods are contained in the GAMS rule.

In addition ones to the organizations mentioned become often also active:

1. The police
2. Authorized person of the company, whose product withdrew
3. The emergency service
4. Experts and expert, the one advisory function notice (e.g. in the context of TUIS)

First remedial measures by layman aids locally

A layman recognizes on the basis the danger property board and danger note that it concerns a traffic accident with danger property. These two Anschrifften are to be noticed very importantly for the emergency call and unbeding.

In danger property goods the generally following elementary basic rules apply to layman aids locally present:

• Smoking as well as drinking and food intake are to be stopped immediately.
• Igniting and sources of fire
  • If possible other open sources of fire in the environment are to be deleted. This may happen however only considering the intrinsic safety of the aid!
  • Autoengines turn off, if still safely possible!
• Warn immediately standing around and hold you for distance from the misfortune place.
• The danger zone is to be left against the wind direction or rectangular for wind direction.
• An emergency call is to be set off. One considers:
  • The directing center is to be informed about the fact that danger property is involved in the accident.
  • Trucks with danger property are characterized by orange colored warning notices. The number standing on it is for the directing center of large importance. It should be conveyed therefore after possibility in the emergency call telephone call.
  • quantity if necessary running out, it is a difference indicates whether it drips from the tank car, or which ran out whole tank broken and already nearly.
• Help is to be rendered to victims outside of the danger zone.
• The moving forward auxiliary workers wait for and instruct

Effects of danger property goods

The possible effects (damage) cover an extremely broad spectrum, under it

1. health damage for humans and animals in the environment of the accident scene
2. Damage of the environment (e.g. poisoning of drinking water, contamination of air, damage to plants etc.)
3. material damage for the company concerned, whose product withdrew
4. Infrastructural damage (blocked roads and such a thing)

Schwerstwiegende of danger property goods can lead to chemistry disasters.
