N: 1. Within COSHH a “substance hazardous to health” means:
- Chemicals and products containing chemicals.
- fumes, mists, vapours.
- toxic gases and asphyxiating gases.
- biological agents (micro-organisms). If the packaging has any of the hazard symbols then it is classed as a hazardous substance.
- micro-organisms in the environment that cause diseases such as leptospirosis or legionnaires’ disease and micro-organisms used in laboratories.
2. It is a common misconception that risk assessment is the identification of the hazardous properties of a substance. The hazardous properties of a substance constitute its potential to cause harm. The risk is the likelihood that it will cause harm in the actual circumstances of use. An assessor must appreciate the difference between these two concepts.
3. health hazard: Substance that is carcinogen, corrosive, irritant, toxic, or can damage eyes, lungs, mucous membranes, or skin, or which produces acute or chronic health effects.
