Interoperability, an important feature of the NIMS, refers to the ability of:

agencies of different types or from different jurisdictions to communicate with each other.

Upon arriving at a scene in which the incident command system has been activated, you should expect to:

be passed from sector to sector, as needed, in between assignments.

A carboy is a container that would MOST likely be used to store and transport:

corrosives.

A 49-year-old man has been removed from his overturned tanker, which was carrying a hazardous material. The tank ruptured and he was exposed to the material. When rescue personnel bring him to the decontamination area, they note that he is unconscious and has slow, shallow breathing. They should:

cut away all of the patient's clothing and do a rapid rinse to remove as much of the contaminating matter as they can.

You and your partner are the first to arrive at the scene of a motor vehicle accident. As you approach the scene, you can see multiple patients, some walking and others who are still in their vehicles. You should:

declare a multiple-casualty incident and request additional resources.

The process of removing or neutralizing and properly disposing of a hazardous material is called:

decontamination.

During a motor vehicle collision involving multiple patients, the incident commander would MOST likely:

designate a safety officer, but retain other command functions.

The purpose of the incident command system (ICS) is to:

ensure responder and public safety, achieve incident management goals, and ensure the effective use of resources.

As the first-arriving senior EMT at the scene of an incident, you should perform a scene size-up and then:

establish command.

A large tanker truck has overturned on a highway. When you arrive, you see a clear liquid leaking from the rear of the tanker. The driver, who appears to be unconscious, is still in the vehicle and is bleeding heavily from the face. You should:

fully assess the situation and request the appropriate assistance.

General principles for approaching a potential HazMat incident include:

maintaining a safe distance and viewing the scene with binoculars.

You and your partner arrive at the scene where a truck has crashed into a small building, injuring eight people. You immediately request additional ambulances and begin the triage process. The first patient that you triage is a young female who is unconscious and apneic. She has an open head injury and her pulse is weak and thready. You should:

place a red tag on her and continue triaging.

You have a critically injured patient in the back of your ambulance, ready to be transported. There are other injured patients at the scene and it will be approximately 10 minutes before other ambulances will arrive. Law enforcement personnel are at the scene. You should:

remain at the scene until at least one other ambulance arrives.

A Level 4 hazardous material:

requires specialized gear designed for protection against that particular hazard.

According to the JumpSTART triage system, infants or children not developed enough to walk or follow commands, including children with special needs:

should be taken to the treatment area for immediate secondary triage.

The reference used as a base for your initial actions at a HazMat incident is:

the Emergency Response Guidebook.

The MOST appropriate location to park your ambulance at a HazMat incident is:

upwind at least 100 feet from the incident.
