EMT CHAPTER 44

At the scene of a hazardous materials emergency, you have been assigned to the cold zone. In this zone, which type of activities will you be performing

Triage, vital signs, and medical histories

An intoxicated driver drove his car into the side of a slow-moving train, hitting a tanker car. You recognize the need to call CHEMTREC to get information on what is contained within the tanker. Which piece of information is it critical to provide to this agency so it can respond with helpful information

UN identification number

How long can a person who has radiation sickness expect to have symptoms

Up to 7 or 8 weeks

If the red diamond on a National Fire Protection Association placard contains a "4," the EMT should recognize that the material within this container is:

Very flammable

What is the LEAST reliable way to determine the presence of hazardous materials

Your senses

Which statement demonstrates that the EMT has a proper understanding of basic operations at the scene of a hazardous materials emergency

"Life or health of the EMS providers should never be risked if the threat is only to the environment

What is one of the most common criminal uses of hazardous materials that the EMT is likely to encounter

A methamphetamine lab

Where is at EMT at highest risk for exposure to phosphine gas

A methamphetamine lab

The EMT would best describe a hazardous material as

Any material that poses a threat to life

When relying on your senses to determine whether a hazardous spill has occurred, you should

Assume that the area around any leak is hazardous

You are working the scene of a collision involving a tractor-trailer that is hauling an unknown chemical. After it has been determined that no material has been spilled, the rescue chief asks you to get the truck's shipping papers. Where would these papers most likely be located?

Cab of the truck

Which class of chemicals would a terrorist likely use in an attack

Class 2 Gases

Which class of hazardous materials includes radioactive sources that may be exploited by terrorists in an attack

Class 7

You are at a scene where a radioactive material is emitting alpha rays. As a knowledgeable EMT, you recognize that the proper shielding from these rays can be achieved by:

Clothing

While a factory employee is moving a container of a radioactive liquid, some of the liquid splashes onto his arm. This situation is best be described as

Contamination

A small truck has gone over an embankment. The driver has a head injury and is confused, but is able to tell you that he is hauling N-acetyl-para-aminophenol. Which resource would provide you with the best initial information about this chemical?

Emergency Response Guidebook

You and your partner are the first emergency personnel on the scene of an overturned tanker truck. The driver appears motionless in the cab of the vehicle. You also note liquid leaking from the rear-valve assembly of the tanker trailer. After properly positioning your ambulance, your immediate priority is to

Evacuate people from cars near the tanker

What is the level of training for those who respond to the release of hazardous materials so as to protect people, property, and the environment

First Responder Operations

You have arrived on the scene of a chemical leak at an industrial park. The placard on the leaking container has a "1" in the blue diamond and a "4" in the red diamond, which means the material is

Flammable but represents a low health hazard

On the scene of a hazardous materials emergency, which individual is best suited to provide command and coordination of assets at the incident?

Hazmat specialist

On the National Fire Protection Association hazardous materials classification placard, the blue diamond represents

Health hazard

A worker has been exposed to beta rays given off by a radioactive material, but is not contaminated. He presents to you when the fire department carries him out from the industrial plant in which there was an explosion and partial building collapse. What should you do first?

Initiate your primary assessment

The driver of a truck carrying a radioactive substance accidentally came in contact with the material after getting into a crash on the freeway. You are first on the scene, and a quick observation indicates that the driver still has the powder on his arm. Your immediate action would be to:

Instruct the patient to remain still and wait for the radiation safety officer

What does the "M" in the mnemonic TRACEM stand for

Mechanical

You have arrived at the scene where a tractor-trailer overturned into a small ravine adjacent to the freeway. As you exit the ambulance and are donning your gloves, the driver of the truck approaches and informs you that he was hauling radioactive medical wastes and warns you that there is a car underneath the overturned trailer. Given this situation, what should you do immediately

Move the ambulance upwind and uphill of the scene

When working in the "warm" zone, the EMT must remember that:

Protective gear must be worn in this zone

A patient has received burns to his arm from a beta particle exposure. This type of damage would be classified as A- Radiation poisoning B- Radiation sickness C- Radiation injury D- Radiation exposure

Radiation injury

You have been trained to the OSHA level of "First Responder Awareness." With this level of training, which activities are you qualified to perform

Recognize a potential hazardous materials emergency and call for the appropriate resources

Which mnemonic can be used to help remember the types of damage that can be caused by hazardous materials

TRACEM

A train carrying radioactive materials has derailed. The radiation safety officer informs you that you will be transporting a 31-year-old male who was exposed to the radioactive waves emitted by the material. As such, you should recognize that

The patient represents no contamination threat to you
