MODULE 1UNIT 1

Basic Hazard and Risk Assessment


Unit 1 Learning Objectives

  • ATTHE 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.


Hazard and Risk Assessment

  • Gather information at the scene

    • Size-up

    • Situational awareness


Hazard and Risk Assessment (cont.)

  • Gather information from resources


Surveying the Scene

  • Containers

  • Products

  • Environment


Containers

  • Physical state of product

    • Solid

    • Liquid

    • Gas

  • Pressure

    • Non pressure, low, medium, high

  • Quantity


Containers (cont.)

  • Non Bulk

    • Less than 119 gallons

  • Bulk


Drums

Pails

Bags & Sacks

Boxes & Crates

Carboys

Cylinders

Bottles and Jars

Dewars

Intermediate Bulk Containers (IBC)

Non Bulk Containers


Bulk Containers

  • Highway

  • Rail

  • Storage Tanks


Tanks and Containers

Storage Containers (cont.)


Radioactive Material Containers

  • Excepted (including strong, tight)

  • Type A

  • Type B

  • Type C


Radioactive Material Containers (cont.)

  • Industrial Package I (essentially Excepted)

  • Industrial Package II

  • Industrial Package III


Damage Assessment

  • Container Stressors

  • Container Breaches

  • Release Events

  • Dispersion patterns


Products

  • Hazards

  • Routes of exposure

  • Appropriate PPE

  • Decontamination

  • Medical care


Specialized Marking Systems

  • Pipelines

  • Pesticide Labels

    • Danger

    • Warning

    • Caution


Radioactive Markings


Radioactive Markings at Facilities


Rail Markings


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.


Risk vs. Benefit

  • Benefits

    • Save Lives

    • Reduce damage to property

    • Protect the environment

  • Risks

    • Injury or Death


Risk vs. Benefit (cont.)

  • Protecting Lives

    • Yourself

    • Fellow Responders

    • The General Public

    • The Victim


Risk vs. Benefit (cont.)

  • Protecting Property

  • Protecting the Environment


Exercise 1

  • Basic Hazard and Risk Assessment


Hazard & Risk Assessment


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


Hazard & Risk Assessment


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


Hazard & Risk Assessment


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


Hazard & Risk Assessment


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

  • Information is needed about the:

    • Container

    • Product

    • Environment


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.
