Hazmat Awareness - Operations | Chapter 2

1. In the U.N. system, hazard classes are divided into:

explosive and nonexplosive.

the types of containers they are transported in.

fifteen different classes, ranked from safest to most dangerous.

nine classes that include gases, infectious substances, and miscellaneous.

2. In Canada, general caution signals are:

round.

triangular.

hexagonal.

rectangular.

3. Liquid containers tend to have:

open tops.

pressure gauges.

V-shaped sloping sides.

flat ( or less rounded) ends on tanks.

4. Which of the following statements regarding the Emergency Response Guidebook (ERG) and U.N. four-digit identification numbers is MOST accurate?

U.N. identification numbers can be found in the ERG and on shipping papers.

U.N. identification numbers are listed in the ERG's green-bordered pages.

The U.S. DOT requires all U.N. identification numbers to be listed in the ERG.

Although the ERG can help identify the U.N. identification number, it will not help first responders determine appropriate initial response information.

5. Pressure containers:

do not contain hazardous materials.

can be recognized by their two flat ends.

are constructed out of very flexible material.

have the potential to release a great deal of energy if involved in an incident.

6. What types of materials are first responders MOST likely to find labeled with the marking "hot"?

Sulfur or aluminum

Radioactive substances

Flammable hydrocarbons

Highly compressed gases

7. Generally speaking, labels are designed for:

fixed facilities.

bulk packages.

nonbulk packages.

non-hazardous materials.

8. Peeling or discoloration of a container's finish suggests what type of change?

Nuclear

Physical

Chemical

Physiological

9. Which of the following is NOT a section included in Safety Data Sheets (SDS)?

First aid measures

Physical properties

Regulatory information

NIOSH identification number

10. NFPA 704, Standard System for the Identification of the Hazards of Materials for Emergency Response gives widely recognized methods for indicating the presence of hazardous materials:

at residential occupancies.

for air and water transport.

for long-distance trucking operations.

at commercial, manufacturing, institutional, or other fixed-storage facilities.

11. In the NFPA 704 System, what category does a "W" found in the white background indicate?

Health risks

Miscellaneous

Water reactivity

Waste products

12. The Emergency Response Guidebook (ERG):

is designed primarily for use at fixed-facility locations.

will be more specific and accurate than information on shipping papers.

addresses all possible circumstances that may be associated with a hazardous response incident.

provides guidance to personnel who may be first to arrive at a scene of a transportation incident involving hazmat.

13. In the U.S. and Canada, military markings are:

uniform.

not necessarily uniform.

identical to national systems.

the same as the Globally Harmonized System (GHS).

14. Under ANSI 2535.1, what color means Warning?

Red

Green

Yellow

Orange

15. Chemical Abstract Service® (CAS®) registry numbers are unique numerical identifiers assigned to:

fixed facilities.

transportation hubs.

trucks, tankers, ships, barges, and airplanes that transport hazardous materials.

individual chemicals, chemical compounds, polymers, mixtures, alloys, and some biological sequences.

16. Materials with very little radioactivity that present no risk to the public should be shipped using what type of packaging?

TypeA

TypeB

TypeC

Excepted

17. Time and effort devoted to identifying contents of buildings, vehicles, and containers results in:

higher rates of civilian casualties.

increased injuries to first responders.

greater confusion and chaos at incidents.

greater safety for first responders and the community.

18. When hazardous materials are transported through your area,:

it will be confidential.

there will be 24-hour notice.

you may have little or no warning.

a police escort should be provided.

19. Under ANSI 2535.1, the color blue:

is not used.

is the background color for all signage.

signifies very cold materials such as cryogens.

marks safety information signage such as required PPE.

20. What is a unit loading device?

A large railway cargo container

A type of marine vessel cargo carrier

A mechanized device to automatically load hazardous materials

Containers and aircraft pallets used to consolidate air cargo into a single transportableunit
