1.1 The term ‘risk assessment’ probably first came into common use as a result of the Control of Substances Hazardous to Health Regulations 1988 (commonly known as the ‘COSHH Regulations’ and revised several times since) which required employers to make a ‘suitable and sufficient assessment of the risks created’ by work liable to expose any employees to any substance hazardous to health. Similar requirements had actually previously been contained in both the Control of Lead at Work Regulations 1980 and the Control of Asbestos at Work Regulations 1987.
