Nebosh Exam Question and Answer August 2022


ABC Oil Company is a multi-national organisation that owns and operates Ingens – an offshore oil and gas platform. Ingens is located in deep water, about 100km from the coast, and extracts and
processes oil and natural gas taken from beneath the seabed. Ingens is spread over several storeys
and includes accommodation for workers and a helipad on the top level. Records show regular
inspection and maintenance of the platform structure, equipment and systems.
Ingens operates 24 hours a day, 365 days a year, working over 2 shifts. The workforce includes
permanent ABC workers and contractors. There has always been extensive use of contractors on
Ingens and there are clear lines of communication between the contractors and the ABC workers.
An Offshore Installation Manager (OIM) has overall responsibility for Ingens including health and
safety, supported by shift managers. The OIM agrees the content of, and signs off, the health and
safety policy.
Findings from past incidents on some of ABC’s other platforms have led to safety improvements on
Ingens. This includes equipment, processes and procedures. Ingens has a reporting procedure in
place for near misses and accidents. However, there have been no serious incidents reported in the
last year, although there have been a few near misses.
On arrival on Ingens, ABC workers receive induction training from shift managers which includes
basic first-aid and manual handling training, site rules and emergency procedures (which are
practised regularly). Site rules include the requirement for personal protective equipment (PPE) to be
worn at all times, and to carry a two-way radio which will be issued after induction. Some contractors
have complained that they may not receive inductions until several days after arriving on Ingens.
During these contractor inductions, those responsible for health and safety are identified, such as the
OIM and shift managers. The content of the health and safety policy is also communicated during all
There are several first-aiders on Ingens spread across different shifts. There is also a well-equipped
medical room (that has specialist lifesaving equipment) staffed by a trained paramedic. If, following
an accident, medical evacuation is necessary, the procedure in place is to make the area safe, treat
the injured, and the OIM calls the nearest ABC onshore control facility for a helicopter.
On Ingens, most tasks operate under a permit-to-work system. The site rules say that no-one should
be allowed to work without a permit-to-work (PTW), the specific requirements of which should be
communicated prior to starting work.
The OIM and shift managers have daily safety meetings, and information from these meetings is
communicated to workers. The OIM also monitors health and safety, carrying out regular audits, and
expects shift managers to perform regular safety inspections. The OIM is also expected to carry out
annual health and safety performance reviews.
Both the OIM and the shift managers are highly respected by workers and contractors. If workers
have any health and safety concerns, they are comfortable talking to them as they know they will be
heard. The OIM and the shift managers are often seen speaking to workers and contractors.
During a dark, rainy day, after a violent storm the night before, two workers walked past staircase 10
exposed to the prevailing weather conditions. They noticed a light was damaged and hanging from
its fitting above the staircase. They reported the issue to the day shift manager. Several hours
passed, and it was almost the end of the shift before the day shift manager remembered to address
this. They decided to leave a note for the night shift manager to send someone to look at the light.
During the handover, the night shift manager read the message but decided not to deal with it
straight away because they would have to produce a safe working procedure and a PTW. No other
workers were warned about the poorly-lit staircase 10.

Two contractors (one of them a young worker) arrived on Ingens for the first time, to carry out some
work near to the top of staircase 10. Although they had not received an induction, they were asked
to start night-work immediately. The intention was to give them their full induction the following
afternoon. In the meantime, they were given a written summary of the health and safety policy
including site rules and reporting procedures. They were anxious to start work, so put the information
in their pockets to read later while they hurried to find the location of the job.
The two contractors decided to use staircase 10 to access the job location while carrying heavy tool
boxes. They were talking about how tired they were due to the long journey to get to Ingens. Even
so, the younger contractor was keen to start the job. As they started climbing staircase 10, the young
contractor stepped onto the second step, which collapsed under them. As a result, they fell directly
onto the platform below. Due to the poor visibility, the older contractor shouted down to the injured
contractor who was unresponsive. The older contractor shouted for help in a very agitated state
trying to get someone’s attention.
After a couple of minutes, another worker responded to the contractor and raised the alarm via their
two-way radio. It took ten minutes for a first-aider to get to the casualty because they were on the far
side of Ingens. Access to the injured contractor was further delayed due to the broken step. The
first-aider found the worker unconscious and suspected serious internal injuries. Noting the
seriousness of the injuries, the first-aider summoned the paramedic and alerted the OIM. The OIM
arranged for a medical evacuation.
The paramedic stabilised the injured person and moved them to the medical facility. The OIM saw
that the older contractor was in shock and insisted that they were taken to the OIM’s office. The OIM
instructed the shift manager to cordon off the staircase area and tell the workers to leave the scene
as it was. The OIM arranged for photographs to be taken of the area.
The OIM returned to their office and asked if the older contractor was ready to discuss the accident.
They asked if they could record the discussion so that it could be referred to when compiling the
report. The OIM then had a similar discussion with the first-aider and the paramedic. The OIM
noticed that the first-aider appeared to be traumatised as they were not saying much. Following
these discussions, the OIM revisited the scene of the accident to survey the area again and found
that the step that had failed appeared to have been severely corroded from beneath.
Due to the accident, all work had to be stopped on Ingens until the medical evacuation was carried
out, some 2 hours after the accident. The young contractor spent 2 weeks in hospital and was off
work for 6 months recovering from the injuries sustained in the fall. The first-aider also needed
counselling and was off work for 2 weeks.
