IOG1 Nebosh, Top Exam Questions and
answers, 100% Accurate. Graded A+

In your safety role on an offshore oil production platform, you have been asked to take part in a risk
assessment and subsequent procedures for the preparation and repair of a large, electrically-driven
pump containing a hot, flammable liquid. The pump needs to be stopped, the large suction and
discharge valves closed, the pump contents removed and the pump inerted before the repair is carried
out.

A. Identify hazards AND, in EACH case, outline an associated risk

with the preparation of the pump: - ✔✔-- the temperature of the pump and associated pipework
leading to the risk of burns from contact.

- the vertical distance (work at height) leading to falls from height.

- the pump accidentally being started and leading to injury from contact with rotating parts.

- the release of flammable vapour leading to fire/explosion

- the gas used for inerting will reduce the oxygen concentration and may lead to asphyxiation

- the use of excessive force to close valves leading to manual handling injury.
