NEBOSH (The National Examination

In many answers there was insufficient detail given to support an ‘outline ‘question. It appeared that some candidates had not read the question with sufficient care and referred to whole body vibration despite the reference to a hand-held piece of

In answering part (a), candidates should have outlined that, 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 and can be reversible. 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. Answers to this part of the question were to a reasonable standard though some candidates had difficulty in differentiating between chronic and acute effects and which was reversible and which was not.
For part (b), candidates should have identified factors such as the route of entry of the toxic substance into the body and the associated mode of exposure; the concentration, physical state and toxicity of the substance; the level, duration and frequency of exposure; the effectiveness of control measures in place; and personal factors such as the age, gender, health status and susceptibilities of those exposed.
Answers were generally to a reasonable standard though a few candidates were
