IOG1 NEBOSH QUESTIONS & ANSWERS
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: Answer - - 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.

before the repair is carried out.
, B. Outline control measures that should be taken for the repair of the pump
Answer - - isolation of electrical power
- isolation of pipelines (various means, such as blanks/spades) releasing stored
energy
- the use of LOTO
- allowing hot machinery to cool
- the use of barriers or fences to segregate the work
- the provision of safe access equipment such as scaffolding
- the issue of permits
- the use of PPE, such as respirators, chemical suits
- the use of trained and skilled personnel and the monitoring of the
atmosphere for potentially flammable conditions.

C. Identify locations where locks and associated tags should be applied for Lock
Out, Tag Out (LOTO). Answer - - the electrical isolator associated with the
electric motor;
- the inlet or outlet valves and the key control boxes within the control room
