A risk assessment has three purposes: • to identify all the factors which may cause harm to employees and others (the hazards); • to consider the chance of that harm actually befalling anyone in the circumstances of a particular case, and the possible conse- quences that could come from it (the risks); and • to enable employers to plan, introduce and monitor preventive meas- ures to ensure that the risks are adequately controlled at all times. Without effective assessment there can seldom be effective control. Job safety analysis The approach is both diagnostic and descriptive. It may be job-based or activity-based. • Job-based: Machinery operators; fork lift truck drivers • Activity-based: Manual handling operations; roof work; cleaning activities.
