Answer the 10 questions. You need 80% or more to pass. You can retry as many times as you like.

Question 1What is the main difference between a risk assessment and a JHA/JSA?A JHA/JSA only applies to office workA risk assessment is illegal in most countriesA JHA/JSA breaks a specific job into steps and analyses the hazard at each stepThere is no difference; the terms mean the same thing

Question 2A hazard is best defined as:Anything with the potential to cause harmThe cost of a safety programmeThe number of workers on siteA completed inspection form

Question 3Which is the correct order of the five steps of risk assessment (HSE INDG163)?Record → review → identify hazards → who is harmed → controlsBuy PPE → train → inspect → audit → certifyReview → record → controls → severity → likelihoodIdentify hazards → who might be harmed → evaluate & decide controls → record → review

Question 4In a 5×5 matrix, how is the risk rating calculated?Likelihood + number of workersSeverity minus the budgetLikelihood multiplied by severitySeverity divided by likelihood

Question 5On a 5×5 matrix, a risk scored 20 (e.g. likely × catastrophic) should be:Ignored because it is only a numberClassed as low risk and just monitoredFiled without any controlsTreated as extreme — stop or do not start until reduced

Question 6According to the hierarchy of controls, which is the MOST effective?Providing personal protective equipment (PPE)Eliminating the hazardPutting up a warning signWriting a procedure

Question 7Why is PPE considered the weakest control in the hierarchy?It protects only the wearer, can fail if misused, and does nothing to the hazard itselfIt is always too expensive to buyIt is banned under ISO 45001It removes the hazard completely

Question 8What is 'residual risk'?The risk that remains after controls have been put in placeThe risk before any controls are appliedThe cost of the controlsA type of PPE

Question 9When building a JHA/JSA, the second step (per OSHA 3071) is to:Issue PPE to all workersBreak the job into a sequence of stepsClose the job down permanentlyFile the analysis and never review it

Question 10When should a risk assessment be reviewed?Never — once written it is finalAfter a change or incident, when controls fail, when new information arises, and periodicallyOnly when an inspector visitsOnly at the very end of a project
