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

What is a hazardous substance?
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 1910.1200 (c)
• Bottom line: Adversely affects health or safety (not only chemicals . . .)

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

EVERYWHERE
• Setting is artificial distinction– Familiarity creates false comfort
• Things we know, context we don’t– Medical O2 vs. Industrial O2
• Location doesn’t modify nature*• Awareness recognizes potential
harm

All HazardsAll 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

Specific hazardsSpecific hazards
• Things that are infectious• Things that explode• Things that burn, shock• Things that are corrosive• Things that are radioactive• Things that cause cancer• Things that are poisonous through
other means• “Others”
