Many substances have hazards associated with them. The term hazardous substances includes biological and micro-organisms, laboratory reagents, common cleaning products, engineering oils, woodworking dusts, and soldering fluxes to mention a few. Often the hazards are affected by the physical form of the material, for instance whether the substance is a solid, liquid, gas, or nanomaterial.
The risks associated with hazardous substances are that they may cause injury or affect your health, or damage the environment; they may be highly reactive; cause fire or explosion; or react with other materials to generate other hazards. There are also risks associated with the use to which the substances might be put or when they are disposed of.
Guidance on how to obtain information about the properties of chemicals or gases is provided in the safety data sheets from the supplier. The University has provided guidance on how to interpret these - please refer to this before purchasing or using the substance as you may need additional storage cabinets, engineering controls (such as fume cabinets, glove boxes), specialist personal protective equipment and a new waste stream to consider. For more guidance relating to this and other hazards in laboratories, see also Laboratories, Workshops & Associated Stores and the Chemical Segregation pages.
Laboratories, workshops, cleaning activities and other facilities or activities that handle or generate hazardous substances must be risk assessed.
Substances with additional requirements
Below is a list of materials which may have requirements in addition to the substance assessment. Further useful links can be found in the right column:
|Lead or Lead Compounds||Lead or lead compounds might be disturbed, displaced or released into the atmosphere, whether that be through maintenance or research activities. This includes metallic lead, its alloys, and all its compounds (including lead alkyls) whether as discrete materials or as a component element of another substance or material (such as a paint or a solder)|
|Drug Precursors – (Home Office requirements) due to their potential for mis-use|
|Controlled Drugs (Home Office requirements)
|Substances covered by the Chemical Weapons Convention|
