Employees can be exposed to chemical agents in the workplace.

  • Identify FOUR forms that chemical agents can take.
  • Outline the differences between the acute and chronic health effects from exposure to chemical agents.

Part (a)

Chemical agents can be present in many forms such as:

  1. Dusts and fibres,
  2. Fumes,
  3. Gases,
  4. Vapours,
  5. Mists and aerosols,
  6. Liquids and

Part (b),

In the case of acute health effects, the adverse effects appear after a single or short term exposure to the agent, and the response is invariably rapid or immediate.

In most cases, acute effects recede on cessation of exposure.

Chronic health effects, on the other hand, usually result from prolonged or repeated exposure to the agent.

The response is normally gradual, may go unrecognised for long periods of time but is often progressive and irreversible.
