Basic Hazard and Risk Assessment


Unit 1 Learning Objectives

• AT THE CONCLUSION OF THIS UNIT THE STUDENT WILL DESCRIBE HOW TO RECOGNIZE A HAZARDOUS MATERIAL THAT IS MARKED AND PERFORM ASSESSMENT ON THE DEFENSIVE ACTION NECESSARY TO PREVENT THE INCIDENT FROM GETTING LARGER.


Student Performance Objectives• Describe how to perform a scene

survey• Identify basic contents of small

containers based on shape and size.• Identify basic contents of highway

transport containers based on shape and size

• Identify basic contents of rail transport containers based on shape and size.


Student Performance Objectives

• Identify basic contents of fixed site containers based on shape and size.

• Identify radioactive materials based on markings and placards.

• Describe how to make a damage assessment on containers.

• Recognize specialized marking systems and products.


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.

Radioactive Markings at Facilities

Radioactive Material Licensee Activity Warning Signage

These signs (called postings) are completely different from transportation placards and labels. The Emergency Response Guide is not applicable.

Obtaining additional Information


Environment

• Be alert for sources of ignition, conduits from the site (such as sewers or drains), streams and bodies of water, and other means of transportation.

Exercise 1

• Basic Hazard and Risk Assessment


Hazard & Risk Assessment


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


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.


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


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?


Summary

• Information is needed about the:ContainerProductEnvironment


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.
