A risk assessment is the process of identifying hazards, evaluating risks and controlling or eliminating those hazards during daily tasks and activities. This also involves applying control measures to make sure your people and any visitors to your site are safe. Ultimately, you have to decide what might cause harm to people and take reasonable steps to prevent that harm. If you employ over five people, you must keep a written record of all of your assessments. If you don’t? You could face a fine or even prosecution.
