What is a hazardous substance? Any substance... –Solid –Liquid –Gas –Other Capable of harming... –People –Property –Environment Any substance... –Solid –Liquid –Gas –Other Capable of harming... –People –Property –Environment

What is a hazardous substance? Any substance to which exposure –“Results or may result in adverse affects on the health or safety of employees” –“Any chemical which is a physical hazard or a health hazard” OSHA 29 CFR (c) Bottom line: Adversely affects health or safety (not only chemicals...) Any substance to which exposure –“Results or may result in adverse affects on the health or safety of employees” –“Any chemical which is a physical hazard or a health hazard” OSHA 29 CFR (c) Bottom line: Adversely affects health or safety (not only chemicals...)

“All Hazards”

Knowledge that you have Applied to unknown situations Common, standard approach –Instills confidence –Quells fear –Ensures safety, always Prepared for the mundane = Prepared for the exotic Knowledge that you have Applied to unknown situations Common, standard approach –Instills confidence –Quells fear –Ensures safety, always Prepared for the mundane = Prepared for the exotic

Hazards = Potential Events Awareness identifies hazards “Guns don’t kill people...” Potential depends on scale and scope –Spill coffee –Spill sarin –Spill oil (tanker) Awareness identifies hazards “Guns don’t kill people...” Potential depends on scale and scope –Spill coffee –Spill sarin –Spill oil (tanker)

Where do hazards exist? EVERYWHERE Setting is artificial distinction –Familiarity creates false comfort Things we know, context we don’t –Medical O 2 vs. Industrial O 2 Location doesn’t modify nature* Awareness recognizes potential harm EVERYWHERE Setting is artificial distinction –Familiarity creates false comfort Things we know, context we don’t –Medical O 2 vs. Industrial O 2 Location doesn’t modify nature* Awareness recognizes potential harm

All Hazards People at risk = hazard Site independent Preparation and prevention is the same Scale and scope is different Intent is the confounding factor Remove intent, left with event People at risk = hazard Site independent Preparation and prevention is the same Scale and scope is different Intent is the confounding factor Remove intent, left with event
