Harmful substances

• A harmful substance is any material/substance with the potential to cause illness or injury to people who come into contact with it.

• A substance may be hazardous because it is explosive, flammable, harmful, irritant, corrosive, toxic, produces a chemical reaction or an allergic reaction.

Harmful substances

In the UK every year:

•2.2 million people suffer work-related ill health

•6,000 die as a result of work-related cancer

•500 die from other work-related diseases

•39 million working days are lost.

The estimated cost of the above is £4–£6 billion.

Legislation

The Health and Safety at Work Act 1974

The Health & Safety at Work Act 1974 “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 and 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 undertaken.

The COSHH Regulations 2002

Designed to protect employees and others from the effects of harmful substances.

Provides more specific guidance than the general arrangements.

Outlines an eight-step approach to managing harmful substances in the workplace.



9 of 18

The 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 (e.g. a label) and, if supplied for use at work, in a material safety data sheet (MSDS).

•Package the chemical safely.

Form of the substance

Solid – Liquid – Gas

Dust – The term used for small particles of a solid suspended in the air.

Vapour – The term used to describe the gaseous state of solids or liquids.

Fumes – Formed when solid vapours condense in the atmosphere.

Mists – Small liquid droplets that form when a liquid is atomised.



12 of 18

Changes of physical form

• Solid to dust, e.g. asbestos and hardwood dust

• Liquid to vapour, e.g. petrol

• Solid to fumes, e.g. lead oxide, chlorine gas

• Liquid to mist, e.g. paint spray, pesticides

Prevent or control exposure Hierarchy of controls:

•Eliminate

•Substitute

•Isolate

•Reduce exposure – engineering controls

•Reduce exposure – procedural controls

•Personal Protective Equipment

•Welfare facilities



15 of 18

Reduce exposure – procedural controls

• Reduce numbers exposed to the hazard.

• Reduce duration of exposure.

• Prohibit eating/drinking/smoking.

• Provide welfare facilities.

• Ensure good personal hygiene.

• Ensure safe storage of harmful substances.

• Ensure safe systems of work for routine and non-routine activities.



16 of 18

Personal Protective Equipment (PPE)

• Use as a last resort if only control measure.

• The hazard remains unaffected.

• Its effectiveness relies on correct use.

• Only the wearer is protected.

• Effectiveness may be reduced over time.

• Supplied, maintained, cleaned, stored and replaced free of charge.

• May require specialist fit testing etc.

• May require specialist disposal.

• Can be uncomfortable to wear.



17 of 18

Golden rules for safety

• Always check labels before use.

• Only store in suitable and labelled containers.

• Store chemicals in a secure area.

• Never mix chemicals without appropriate advice and guidance.

• Always wear appropriate PPE correctly.

• Clear up spillages immediately.

• Follow safe systems of work practices.

• Report any symptoms of ill health immediately.

• Report any operational or equipment failures.
