9.18 Observations

Sufficient observations must be made to arrive at a conclusion on the adequacy of control measures for exposures to all the hazardous substances in the workplace be they raw materials, products, by-products, waste, emissions, etc. This should include the manner and the extent to which employees (and others) are exposed and an evaluation of the equipment and working practices intended to achieve their control.

Aspects to be considered include:

• Are specified procedures being followed?

• Does LEV or general ventilation appear effective?

• Is PPE being used correctly?

• Is there evidence of leakage, spillage or dust accumulation?

• What equipment is available for cleaning?

• Are dusts, fumes or strong smells evident in the atmosphere?

• Are there any restrictions relating to eating, drinking or smoking?

• What arrangements are there for storage, cleaning or maintenance of PPE?

• Are there suitable arrangements for washing, showering or changing clothing?

• Are special arrangements for laundering clothing required?

• What arrangements are in place for storage and disposal of waste?

• Is there potential for major spillages or leaks?

• What emergency containment equipment or PPE is available?

Obviously this list could be extended significantly and some of the aspects could be broken down into further sub-components.
