HAZARD STATEMENTS
There are 72 individual and 17 combined Hazard statements - these are assigned a unique alphanumerical code which consists of one letter and three numbers as follows:
- the letter "H" (for "hazard statement");
- a number designating the type of hazard as follows:
- "2" for physical hazards
- "3" for health hazards
- "4" for environmental hazards
- two numbers corresponding to the sequential numbering of hazards arising from the intrinsic properties of the substance or mixture, such as explosive properties (codes from 200 to 210), flammability (codes from 220 to 230), etc.
