“It shall be the duty of every employer to ensure, so far as is reasonably practicable, the health, safety and welfare of all employees”:

– Safe plant and systems of work

– Safe use, handling, transport, storage of substances and articles

– Provision of information, instruction & training

– Safe place of work including access and egress

– Safe working environment with adequate welfare facilities

– A written safety policy if more than four employees

Further duties extend this requirement to include non employees who may still be affected by the work undertaking

The CHIPS Regulations 2002The CHIPS Regulations 2002

CHIP requires the supplier of a dangerous chemical to:

Identify the hazards (dangers) of the chemical, this is known as ‘classification’;

Give information about the hazards to their customers. Suppliers usually provide this information on the package itself (eg a label) and, if supplied for use at work, in a material safety data sheet (MSDS);

Package the chemical safely

Nursing home faces chemical alert

Thirteen residents had to be evacuated from a nursing home after chlorine-based chemicals were accidentally mixed together. Firefighters were called to the Nyton House Nursing Home, in Aldingbourne, West Sussex, on Wednesday morning to a strong smell of chlorine fumes.

The chemicals had been placed in a bucket, but were removed by fire crews to a sealed container. Four people were treated in hospital for the effects of the fumes.

West Sussex Fire and Rescue Service said it seemed two chlorine-based chemicals used for the swimming pool at the nursing home had been mistakenly mixed together by a workman, causing the release of the fumes

Assessing The RiskAssessing The Risk

Describes the likelihood of harm occurring:

Risk = Severity of Harm x Extent of Exposure

Amount Of SubstanceAmount Of Substance

Can be difficult to determine

Factors to consider include:

– Varying concentrations over time– Duration of exposure– Accurate measuring of quantities– Changes to form of substance

The disease or health effect may be related to exposure There is a likelihood that the disease or health effect

may occur There are valid techniques for detecting indications of

the disease or health effects exposure to a substance linked to a particular disease or adverse health effects
