Hazmat Awareness - Operations | Chapter 9

1. Which of the following statements about CPC is MOST accurate?

CPC protects against all types of chemicals.

CPC is only made from one type of material.

It is appropriate for flammable environments.

No single type of CPC can protect against all hazards.

2. Rehabbing in a warm area and avoiding cold beverages can help prevent:

heat stress.

claustrophobia.

cold emergencies.

psychological issues.

3. Why/how can CPC contribute to heat disorders in hot environments?

It can degrade.

It absorbs sunlight.

It is designed to be impenetrable to moisture.

It allows penetration of hot fluids from the outside.

4. Which statement is MOST accurate about choosing PPE ensembles?

Chemical and physical hazards are less important selection factors when the duration of exposure is expected to be less than 15 minutes.

Because the IC will select the appropriate level of PPE to be used at an incident, a responder does not need to understand the selection process.

Overprotection, as well as underprotection, can be hazardous and should be avoided.

The highest available PPE should always be used in case there are unexpected hazards.

5. Particulate-removing filters on APRs are used to protect the user from materials such as:

asbestos.

carbon monoxide.

low oxygen atmospheres.

fireground gases and smoke.

6. How does wearing PPE increase the risk of heat-related disorders?

Most PPE has no effect on body temperature.

Most PPE provides automatic cooling technology.

Most PPE increases the body's ability to disperse heat and moisture.

Most PPE inhibits the body's ability to disperse heat and moisture.

7. What organization has established a set of chemical-protective PPE ensembles providing certain protection levels that are commonly used by fire and emergency service organizations?

Environmental Protection Agency (EPA)

National Fire Protection Association (NFPA)

International Association of Fire Fighters (IAFF)

National Institute of Occupational Safety and Health (NIOSH)

8. What is it called when characteristics of a material are altered through contact with chemical substances?

Permeation

Penetration

Degradation

Contamination

9. How do law enforcement first responder ensembles differ from fire service first responders?

Fire service personnel will typically carry a sidearm.

Fire service personnel will typically wear ballistic protection.

Law enforcement personnel will typically wear ballistic protection.

Law enforcement personnel will typically wear higher levels of respiratory protection.

10. When a chemical passes through a fabric on a molecular level, it is called:

permeation.

penetration.

degradation.

contamination.

11. Which statement about the service life of CPC is MOST accurate?

CPC ensembles have no specific service life.

Always follow AHJ SOP/Gs and manufacturer's specifications in regards to serviceability.

If a CPC garment is discolored, it is still perfectly usable as long as the serviceability date has not passed.

A CPC suit used in the hot zone does not need to be decontaminated unless contamination is verified visually.

12. A supplied-air respirator (SAR) used at a hazmat incident must:

carry/supply its own air.

be certified for firefighting operations.

provide positive pressure to the facepiece.

have an airline of longer than 300 feet (90 m).

13. The extreme hazards associated with materials that could be used in terrorist attacks has prompted the U.S. Department of Homeland Security to:

regulate who can be a first responder at hazmat/WMD incidents.

recommend that only APRs be used during hazmat/WMD incidents.

adopt standards for respiratory equipment to protect responders at hazmat/WMD incidents.

mandate that first responders at all hazmat/WMD incidents be certified to the Technician level.

14. APRs must be used only in atmospheres that are NOT oxygen deficient or oxygen enriched and are not IDLH because:

the ambient air supplies the oxygen.

the air generator may fail at any moment.

the purifying canister may be expired or damaged.

the responder may not properly use the equipment.

15. What is a common limitation of respiratory equipment?

Enhanced visibility

Increased mobility

May cause shortness of breath

Decreased ability to communicate

16. What is the most serious type of heat disorder?

Heat stroke

Heat rashes

Heat cramps

Heat exhaustion

17. When using SCBA, where does the air supply come from?

The ambient air

The user carries it

A stationary air cylinder

A large stationary generator

18. How do EMS ensembles differ from fre service first responders?

EMS PPE includes a sidearm.

EMS personnel must wear ballistic protection.

EMS personnel will typically wear higher levels of respiratory protection.

EMS PPE must provide blood- and body-fluid pathogen barrier protection.

19. Which of the following is most likely NOT to be a factor for selecting protective clothing?

Cost

Size of incident

Ease of decontamination

Material chemical resistance

20. Level D PPE consists of:

typical work uniforms, street clothing, or coveralls.

hooded chemical resistant clothing and full-face or half-mask APRs.

typical work uniforms, street clothing, or coveralls with the addition of a half-mask APR.

hooded chemical resistant clothing and positive-pressure, full facepiece, SCBA, or positive-pressure respirator with escape SCBA.
