IOG1 NEBOSH EXAM 2025 LATEST UPDATE ACTUAL QUESTIONS WITH COMPLETE SOLUTIONS

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: - CORRECT 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. 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. B. Outline control measures that should be taken for the repair of the pump - CORRECT 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. 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. C. Identify locations where locks and associated tags should be applied for Lock Out, Tag Out (LOTO). - CORRECT ANSWER - the electrical isolator associated with the electric motor; - the inlet or outlet valves and the key control boxes within the control room 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.
