Hazard & Risk Assessment

HazMat Operations Unit 1 slide 45

Slide one

• Risk = LowVictim is alive with

no protective equipment.

What PPE can we wear

Little if any Contamination

• Benefit = HighVictim will live with

assistance

HazMat Operations Unit 1 slide 46

Hazard & Risk Assessment

HazMat Operations Unit 1 slide 47

Slide two

• Risk = ModerateVictim may still be

alive.What type of PPE

can we wear Little if any

ContaminationNo evidence of the

problem being chemical

• Benefit = ModerateVictim, if alive, will

probably continue to live.

HazMat Operations Unit 1 slide 49

Slide three

• Risk = HighVictim probably is

not alive.Will your PPE protect

you?We will get

contaminated

• Benefit = ModerateVictim even if alive

may not continue to live

HazMat Operations Unit 1 slide 50

Hazard & Risk Assessment

HazMat Operations Unit 1 slide 51

Slide four

• Risk = HighWe do not even

know if there is a victim.

Heavy Contamination is probable

• Benefit = Low If we can not survive

without an SCBA, how can the victim?

HazMat Operations Unit 1 slide 52

Summary

• Information is needed about the:ContainerProductEnvironment

HazMat Operations Unit 1 slide 53

Summary (cont.)

• First responders must conduct a “risk vs. benefit” analysis to help make decisions about the defensive actions they can take to save lives, protect property and the environment.
