Hazardous Substances cont...
Examples of the effects of hazardous substances include:
•skin irritation or dermatitis as a result of skin contact,
•asthma as a result of developing allergy to substances used at work,
•losing consciousness as a result of being overcome by toxic fumes,
•cancer, which may appear long after the exposure to the chemical that caused it, and
•infection from bacteria and other micro-organisms (biological agents).
A COSHH material safety data sheet (often referred to as an MSDS sheet) should be supplied with any hazardous substance at its delivery location. MSDS sheets should always be available to all members of staff and others who may require to handle, move or use the hazardous substance, etc.
The material safety data sheet contains guidelines on what should be done if the hazardous substance accidentally comes into contact with your skin, your eyes, or is ingested orally or possibly absorbed through the skin. It will also include other safety precautions such as what to do about spillages or leaks. Warning labels will be used to classify the types of hazard, such as irritant, flammable, very flammable, toxic, very toxic, corrosive, explosive, sensitising, dangerous to the environment, etc.
The COSHH (hazardous substances controls) Regulations apply to virtually all substances hazardous to health. Exceptions include asbestos and lead (which have their own regulations) and substances, which are hazardous only because they are radioactive or an asphyxiate.
COSHH (hazardous substances controls) requires the following.
•assessment of the risks. (COSHH risk assessment)
•deciding what precautions are needed.
•prevention or control of the risks.
•ensuring that control measures are used and maintained.
•monitoring exposure and health surveillance, where necessary, and,
•informing instructing and training employees about the risks and precautions needed.
Further on the control of substances can be found in ACOP L5 and HSG 97 A step by step guide to COSHH assessment
