What are physical hazards?

Physical hazards are chemicals, substances and products that threaten the physical safety of a human being. Common types of physical hazards include fire, chemical reactions and explosions, according to Instructional Designs.

Chemical physical hazards are classified as chemicals in which scientific evidence can prove the substance is a combustible liquid, either in a compressed, flammable, organic, explosive or gas state, notes OSHA. This includes chemicals that are an oxidizer, a peroxide, a pyrophoric, a reactor or any chemical that is unstable and reactive. Safety is the number one priority in any workplace setting. OSHA provides safety training on the prevention of both physical and health hazards.
