Employers are required to make a suitable and sufficient assessment of the health and safety risks to which their employees are exposed while at work, as well as the risks to non-employees who may be affected by their activities.
Risk assessments must have regard to a number of factors, including the nature and complexity of the employer's activities and the size of the employer's undertaking. Hazard identification can be undertaken using a number of techniques. These include the use of checklists to complete a workplace review; observation of the task and interviews with those involved; and reviews of relevant health and safety legislation and supporting guidance.
