The packaging and storage of industrial gases involves the following types of hazards:
These two hazards may be combined in certain cases. Because of these hazards, all gases are classified as dangerous goods according to legislation.
Another hazard that is common to almost all gases is that of asphyxiation due to lack of oxygen. The second breath of air we take that has been replaced by a gas containing no oxygen will result in unconsciousness. If help is not provided immediately, the victim will die in just a few minutes. For those gases considered to be hazardous because of their specific properties (such as flammability or toxicity), safety information is provided and safety precautions are implemented.
The specific hazards of some gases increase the general level of risk. As with any chemical product, the following characteristics may be hazardous:
