IOSH Managing Safely common mistakes
IOSH Managing Safely · Understand the traps and how to avoid them.
Selects 'zero accidents' or 'eliminate all risk' as the purpose of managing safely.
Everyday safety slogans use absolute language, and candidates answer with what sounds aspirational rather than the legal/managerial standard.
What to do instead
Memorise and use the phrase 'reduce risk to as low as is reasonably practicable (ALARP)'; when an option contains 'all', 'never' or 'guarantee', treat it as a distractor unless the question is specifically about elimination at source.
Uses 'hazard' and 'risk' interchangeably in written answers, e.g., calls a trailing cable a risk or calls a likelihood a hazard.
In everyday speech the two words overlap, so candidates default to casual usage rather than the exam's precise definitions.
What to do instead
Write the two definitions on a flashcard: hazard = something with potential to cause harm; risk = the likelihood and severity of harm from that hazard. Before answering, underline the word the question uses and make sure your answer contains both elements for risk questions.
Gives a risk rating (high/medium/low) without stating the likelihood and severity that produced it.
Candidates memorise the matrix colours but skip the reasoning step, especially under time pressure.
What to do instead
Practise a fixed sentence structure: 'Likelihood is [x] because..., severity is [y] because..., therefore the rating is [z].' Check that your chosen rating matches the descriptors in the matrix you were taught.
Orders controls as PPE, training, engineering, substitution, elimination, or otherwise puts administrative and PPE controls above engineering controls.
The hierarchy is learned as a list to recite rather than as a ranking from most to least effective.
What to do instead
Recite 'Eliminate, Substitute, Engineering, Administrative, PPE' and for every control question ask: 'Is there a higher option still available?' PPE should only be selected when higher controls are not reasonably practicable.
Treats a control as finished once it is selected, omitting monitoring, review and residual risk.
Candidates think of risk control as a one-off decision rather than a cycle.
What to do instead
In any answer about controls, add two clauses: the residual risk that remains after the control, and how and when the control will be monitored and reviewed (e.g., inspection, audit, review after an incident or change).
Assigns employer duties to employees (e.g., says employees must provide PPE or carry out risk assessments) or says employees have no legal duties.
General 'we are all responsible for safety' messages blur the specific statutory split in the exam.
What to do instead
Build a two-column table: employer (safe systems, information, training, supervision, free PPE, risk assessment); employee (take reasonable care, report hazards/defects, follow instructions, use PPE as trained). Test every duty question against the table before answering.
Identifies only physical hazards in a scenario and misses organisational or psychosocial hazards such as poor supervision, fatigue, time pressure or lone working.
Candidates scan for visible machinery, chemicals and slips and stop once they have found one or two.
What to do instead
Use a category checklist for every scenario: physical, chemical, biological, ergonomic, psychosocial, organisational. Force yourself to name at least one hazard from a non-physical category before finalising the answer.
Uses accident, incident and near miss as if they mean the same thing, e.g., labels an event with no injury as an accident.
The terms overlap in normal conversation, and the exam relies on strict definitions.
What to do instead
Learn three one-line definitions: accident = event causing injury or damage; incident = event that did or could have caused harm; near miss = incident with no injury or damage. Sort ten short scenarios into the three categories until the definitions are automatic.
Describes the purpose of incident investigation as finding someone to blame or simply recording what happened.
Workplace culture often frames investigations as disciplinary or form-filling exercises.
What to do instead
Answer with root-cause language: to establish immediate and underlying causes, identify system failures, prevent recurrence and improve controls. Reject options that focus on fault, discipline or blame.
Mixes proactive and reactive monitoring, e.g., calls accident statistics proactive or calls safety audits reactive.
The labels feel intuitive but candidates reverse them under exam pressure.
What to do instead
Use a memory hook: proactive = before the event, predicting and preventing (inspections, audits, training, near-miss reporting); reactive = after the event, recording harm (accident rates, lost-time statistics, compensation claims). Classify twenty examples into two columns until consistent.
