Student performance objectives2
Student Performance Objectives

  • Describe how to obtain further information on a material in an incident.

  • Describe how to assess the scene of an incident weighing risk vs. benefit.


Hazard and risk assessment

Exercise 1
Exercise 1

  • Basic Hazard and Risk Assessment



Slide one

Risk = Low

Victim is alive with no protective equipment.

What PPE can we wear

Little if any Contamination

Benefit = High

Victim will live with assistance

Slide one



Slide two

Risk = Moderate

Victim may still be alive.

What type of PPE can we wear

Little if any Contamination

No evidence of the problem being chemical

Benefit = Moderate

Victim, if alive, will probably continue to live.

Slide two



Slide three

Risk = High

Victim probably is not alive.

Will your PPE protect you?

We will get contaminated

Benefit = Moderate

Victim even if alive may not continue to live

Slide three



Slide four

Risk = High

We 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?

Slide four


Summary
Summary

  • Information is needed about the:

    • Container

    • Product

    • Environment


Summary cont
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.
