Haz Mat Ch.3 Flashcards
What is the purpose of identifying hazardous materials at a hazmat incident?
To determine safe distances for isolation and protection
Safe distances are critical for ensuring the safety of personnel and the public during hazmat incidents.
What resources can Awareness Level Personnel use to identify hazardous materials?
Current edition of the Emergency Response Guidebook (ERG) or other equivalent resource
The ERG provides crucial information on fire, explosion, and health hazards associated with materials.
What information is typically found in shipping documents for hazardous materials?
4-digit UN number, proper chemical shipping name, hazard classes, divisions, and packing group
Shipping documents are essential for initiating protective actions during a hazmat incident.
What does the packing group indicate regarding hazardous materials?
The degree of danger they present
Packing groups help responders assess risk quickly.
What are the three packing groups for hazardous materials?
- Packing Group I: high danger
- Packing Group II: medium danger
- Packing Group III: low danger
Each packing group reflects the potential risk associated with the hazardous material.

[second]
The order of information is crucial for understanding the risks associated with the hazardous material.
What type of hazard information can Awareness Level Personnel identify using the ERG?
- Fire hazards
- Explosion hazards
- Health hazards
Understanding these hazards is vital for effective response and safety.
What is the significance of the 4-digit UN number in shipping documents?
It identifies the specific hazardous material being transported
The UN number is a crucial reference for emergency responders.
What is the purpose of the ERG?
The ERG is a guide to aid emergency responders in quickly identifying the initial hazmat hazards involved in a transportation emergency incident.
How does the ERG help during an incident?
It helps protect responders and others by avoiding and minimizing hazards during the incident’s initial response phase.
Where is the ERG primarily designed to be used?
The ERG is primarily designed for hazardous materials incidents occurring at highways, railroads, and pipelines.
Are the isolation and protective distances in the ERG suitable for all locations?
No, they are based on conditions commonly associated with transportation incidents in open areas and may not be appropriate for fixed-facility locations or urban settings.
Does the ERG address all possible circumstances of hazardous materials incidents?
No, the ERG does NOT address all possible circumstances that may be associated with a dangerous goods/hazardous materials incident.
How can you locate the appropriate initial action guide page in the ERG?
You can locate it by identifying the four-digit UN identification number on a placard, orange panel, or shipping papers, and then looking up the appropriate guide in the yellow-bordered pages.
What is another method to find the initial action guide in the ERG?
Reference the name of the material involved (if known) in the blue-bordered pages. Exact spelling is important when using this method.
What should you do if you identify the material’s transportation placard?
Reference the three-digit guide code associated with the placard in the Table of Markings, Labels, and Placards and Initial Response Guide to Use On-Scene located in the front of the ERG.
How can first responders use the container profiles in the ERG?
First responders can identify container shapes and then cross-reference the guide number to the orange-bordered page provided in the nearest circle.
