Physical hazards pyrophorics

Physical hazard means a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive. 

Physical hazards include noise, vibration, extremes of temperature, compressed gases, combustible and flammable chemicals, pyrophorics, explosives, oxidizers, and reactive materials. Process employees are exposed to physical hazards on a daily basis because they woric outside on the unit among pipes containing compressed gases, fluids under high temperatures, and flammable and explosive chemicals. Examples of some these hazards on a process unit might include ... 

Physical hazard A chemical that is classified as posing one of the following hazardous effects explosive flammable (gases, aerosols, liquids, or solids) oxidizer (liquid, solid, or gas) self-reactive pyrophoric (liquid or solid) self-heating organic peroxide corrosive to metal gas under pressure or in contact with water emits flammable gas. 

Physical hazard of a chemical— A chemical validated as being or having one of the following characteristics combustible liquid, compressed gas, explosive, flannnable, organic peroxide, oxidizing qualities, pyrophoric, unstable, or water reactive. 

A hazardous chemical is any chemical which is classified as a physical hazard or a health hazard, a simple asphyxiant, combustible dust, pyrophoric gas, or hazard not otherwise classified. 

Hazard. Hazard is an inherent property or ability of a substance to cause an adverse effect or event. Classes of hazards include physical hazards (e.g., compressed gases, explosives, flammables, organic peroxides, pyrophorics, unstable and water-reactive materials) and health hazards (e.g., asphyxiants, irritants, systemic toxins, reproductive toxins, carcinogens).
