Look around your job site. There are hazards including suspended loads, moving equipment, heat, electricity, insects, falling objects, poison oak and traffic. Assuming you work for a company with an effective safety program, they have trained you in hazard identification and mitigation. Your mitigation plan to control some hazards includes PPE. You inspect it, store it properly and wear it as directed. In short, you protect it so it can protect you. You are covered in PPE from head to toe and ready to go to work. Or are you? Have you forgotten the most important PPE you will ever use – a mirror?
