What section of ERG contains "ID Number Index"?

Yellow = ID #

What section of ERG contains "Name of Material Index"?

Blue = Name

Within ERG, what entries are highlighted in green?

1. TIH (Toxic Inhalation Hazard)

2. Chemical Warfare agent

3. Dangerous Water Reactive Material

What does the guide number supplemented with the letter (P) indicate?

Material may undergo violent polymerization if subjected to heat or contamination

How are Hazard Classification System divided?

Class 1 thru Class 9

How should you approach the scene?

Upwind, uphill, or upstream

At a safe distance

Read placard or orange panel

If entries are highlighted in green, and THERE IS NO FIRE, what steps should be followed within ERG?

IF THERE IS NO FIRE = Green pages (small or large spill)

If entries are highlighted in green, and IF THERE IS A FIRE or A FIRE IS INVOLVED, what steps should be followed within ERG?

IF THERE IS A FIRE or A FIRE IS INVOLVED = Also consult orange guide

What does an entry with "When Spilled in Water" within green section of ERG mean?

Materials produce large amounts of Toxic Inhalation Hazard (TIH) gases when spilled in water

What area SURROUNDING the incident in which persons may be exposed to dangerous (upwind) and life threatening (downwind) concentrations of material?

Initial Isolation Zone = SURROUNDING

What area DOWNWIND from the incident in which persons may become incapacitated and unable to take protective action and/or incur serious or irreversible health effects?

Protective Action Zone = DOWNWIND

What if more than one tank car containing TIH materials involved in the incident is leaking?

LARGE spill distances may need to be increased

Which Protective Action Distance should be chosen if it is not clear whether the spill is on land or in water, or in cases where the spill occurs both on land and water?

Choose larger Protective Action Distance

What means are to keep everybody away from the area if they are not directly involved in emergency response operations?

Isolate Hazard Area and Deny Entry

What means to move all people from a threatened area to a safer place?


What means people should seek shelter inside a building and remain inside until danger passes?

Shelter In Place

What is used when evacuating the public would cause greater risk than staying where they are, or when an evacuation cannot be performed?

Shelter In Place

What should you direct for Shelter In Place?

1. Close all doors and windows

2. Shut off all ventilating heating and cooling systems

During a Shelter In Place, what is vital to maintain?

Communications with competent persons inside the building

During Shelter In Place, why should persons be warned to stay far from windows?

Danger from glass and projected metal fragments in a fire and/or explosion

What is considered a SMALL SPILL?

Single, small package (less than 55 gallons liquids, 660 pounds solids), small cylinder or small leak from a large package

What is considered a LARGE SPILL?

Spill from a large package, or multiple spills from many small packages, (more than 55 gallons liquids, 660 pounds solids)

What is considered DAY time?

After sunrise and before sunset

What is considered NIGHT time?

Between sunset and sunrise

What symbol or shape is the Protective Action Zone considered for practical purposes?

Square - length and width are the same as the downwind distance

What symbol or shape is shown where the spill is located?

Small circle = Spill is located

What symbol or shape is shown that represents the INITIAL ISOLATION zone around the spill?


What is used to aid first responders in quickly identifying the specific or generic hazards of the materials involved in the incident, and protecting themselves and the general public during the initial response phase of the incident?


What is the period following arrival at the scene of an incident during which the presence and/or identification or dangerous goods is confirmed, protective actions and area securement are initiated and assistance of qualified personnel is requested?

Initial Response Phase

Which section is the index list of dangerous goods in numerical order of ID number?

Yellow bordered pages = Numerical order

Which section is the index list of dangerous goods in alphabetical order of material name?

Blue bordered pages = Alphabetical order

Which section is where all the safety recommendations are provided?

Orange bordered pages = Safety recommendations

How is each guide divided?

1. Potential hazards (fire/explosion/health)

2. Public safety (isolation, clothing, evacuation distances)

3. Emergency response (first aid)

Which section of the guide should responder consult first?

Potential hazards

In what direction(s) from the actual spill/leak source, should the "Initial Isolation Distance" be considered for evacuation?

In all directions

Within the Initial Isolation Distance, what distance defines a circle within which persons may be exposed to dangerous concentrations upwind of the source?

Distance (radius) defines the circle

What item(s) provides limited protection from heat and cold, but may not provide adequate protection from the harmful vapors or liquids that are encountered during dangerous goods incidents?

Structural fire fighter's protective clothing

Why should protective clothing not be used unless it is compatible with the released material?
