DANGEROUS GOODS

Definition.
Dangerous goods are solids, liquids, or gases that can harm people, other living organisms, property, or the environment. They are often subject to chemical regulations. "HazMat teams" are personnel specially trained to handle dangerous goods. Dangerous goods include materials that are radioactive, flammable, explosive, corrosive, oxidizing, asphyxiating,biohazardous, toxic, pathogenic, or allergenic. Also included are physical conditions such as compressed gases and liquids or hot materials, including all goods containing such materials or chemicals, or may have other characteristics that render them hazardous in specific circumstances.

Dangerous goods (often called hazardous materials in the USA) may be pure chemicals, mixtures of substances,manufactured products or articles which can pose a risk to people, animals or the environment if not properly handled in use or in transport. 

Dangerous in Transport
Substances and materials which are dangerous for transport range from those which present obvious risks, such as explosives and fuming acids, through to more frequently encountered products such as paints, solvents and pesticides.The transport of dangerous goods is regulated in order to prevent, as far as possible, accidents involving people or property, damage to the environment, to the means of transport employed or to other goods being transported.  Each mode of transport, (air, sea, road, rail and inland waterway) has its own regulations but they are now largely harmonized with the Model Regulations, published byUnited Nations Economic and Social Council's Committee of Experts on the Transport of Dangerous Goods.
The UN Model Regulations use a classification system in which each dangerous substance or article is assigned to a CLASS, depending on the nature of the danger it presents. There are 9 Classes, some of which are sub-divided:

Classification
A ) Limiting Classes: Classes 1 and 7

Are thosegoods to be transported, must be specifically named and authorized in the ADR / RID. Of these, some are accepted for carriage
Under certain conditions specified in the regulations mentioned above and the remaining are not accepted for carriage.

B) Non-limiting classes: Classes 2, 3, 4.1, 4.2, 4.3, 5.1, 5.2, 6.1, 6.2, 8 and 9
In these, transport is allowed broad groups. It is thereforenecessary that a commodity is explicitly named for authorization to transport. Some of them are excluded by marginal notes inserted in the respective regulations and other pets for carriage under the conditions laid down in its margin. Those not listed are
not considered as dangerous goods and are accepted by carriage without conditions.

DANGEROUS SUBSTANCES: Safety Data Sheets
Royal Decree363/1995 of 10 March, which approves the Regulation on notification of new substances and classification, packaging and labeling of dangerous substances, Article 23 establishes the obligation for the person responsible for marketing a hazardous substance in the development and provision of an information system for professional users.

This information system is called Safety Data Sheets, MSDS.In addition, Annex XI, provides guidance for the development of these chips.
The information to be contained in these MSDS are as follows
:
* Identification of the substance and the body
* responsible for marketing
* Composition / information on ingredients
* Hazard identification
* first aid
* Fire fighting measures
* Measures to be taken in case of accidental* Spillage
* Handling and Storage
* Exposure controls / personal protection
* Physico – chemical
* Stability and reactivity
* toxicological information
* ecological information
* Disposal considerations
* Transport information
* regulatory Information
* other information
