The main aim of occupational risk assessment is to protect workers’ health and safety. Risk assessment helps  minimize the possibility of the workers or the environment being harmed due to work-related activities. It also  helps keep your business competitive and productive. In many countries, under the health and safety laws all  employers must carry out regular risk assessments. In practical terms, a risk assessment is a thorough look at  your workplace to identify those situations, processes and so forth that may cause harm.
