Lecture GoalsLecture Goals

• Define what a hazard is• Define “all hazards” approach• Describe where hazards exist• Explain hazard recognition

• Define what a hazard is• Define “all hazards” approach• Describe where hazards exist• Explain hazard recognition

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



• 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

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)

• 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

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

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

• Scale, scope and intent

• Things that are familiar• Things in unfamiliar context• Things with malicious intent

Flammable liquidsFlammable liquids

• Found in all environments• Often overlooked, ignored as risk• Fire and explosive risk

• Let’s take a look at a familiar example…

GasolineGasoline


• Everything is a potential hazard• Hazards have many faces• Recognize the potential exists• Remove the intent• Prepared and ready


GasesGases

• Found everywhere in a hospital• Flammable, compressed

– Boiling Liquid Expanding Vapor Explosion (B.L.E.V.E.)

• Some are toxic
