Ash and Dan will be working on a project called "Best of British" located at York College. They identified potential hazards including fatigue from overworking, claustrophobia in confined spaces, eye strain from computer screens, and cuts from knives during food preparation. To mitigate these risks, they will take 5 minute breaks every hour, only work in appropriately sized classrooms, take regular breaks from screens, and handle knives safely. They will also need to consider health and safety legislation regarding display screen equipment, suitable working conditions when cooking, and having first aid supplies available.
