ABSTRACT
Candidates have always had most difficulty with the action verb ‘outline’ and, for this reason, several of the specimen questions chosen use ‘outline’ so that some guidance on the depth of answer expected by the examiners can be given. Elimination or substitution is the best and most effective way of avoiding a severe hazard and its associated risks. Elimination occurs when a process or activity is totally abandoned because the associated risk is too high. Substitution describes the use of a less hazardous form of the substance. Reduced or limited time exposure involves reducing the time that the employee is exposed to the hazardous substance by giving the employee either other work or rest periods. A safe system of work is a requirement of the Health and Safety at Work Act and describes the safe method of performing the job.
