Every employer, site manager or contractor has a legal responsibility to take reasonable steps to protect your safety while at work. Under the Health and Safety at Work Act 1974, they must assess workplace risks, provide adequate training and safety equipment, also known as Personal Protective Equipment (PPE) (such as helmets, high visibility clothing, steel toe capped boots, gloves), maintain safe systems of work, and take appropriate precautions to reduce the risk of workers being struck by vehicles, moving equipment, loads, tools or other objects.
Depending on the workplace and the nature of the work being carried out, this may include separating pedestrians from vehicle routes, managing reversing movements safely, ensuring loads and materials are stored securely, maintaining workplace vehicles and equipment properly, and making sure staff are appropriately supervised, trained and given the right PPE.
If any of these duties are breached, and you are injured as a result, you may have grounds to claim compensation. Establishing negligence does not mean your employer intended to cause harm, it simply means that they failed to take reasonable steps to prevent a foreseeable risk of injury.
