1
Q

A first reponders response begins with —, and this particular phase of the incident can determine subsequent success of failure.

A

Dispatch : often the first link in a series of events

2
Q

Clarify both the nature of the incident and the — of any known chemicals that are involved when relaying information.

A

Spelling

phonetic alphabet

3
Q

However, first responders must make every effort to stay — wind from the incident once on scene and remember that DISTANCE from the scene is just as important.

A

Up

4
Q

With larger commercial vehicles the absence of — is no assurance they do not contain a hazardous material.

A

Placards

5
Q
  • BE ALERT FOR LEAKS!
  • look for the company name
  • be alert to suspicious odors
  • ask passengers what’s on board
  • look for shipping papers in cab of vehicle if safe to approach

Are steps to take when dealing with:

A

A delivery truck with no placards or any other clearly stated warning

6
Q

*know this!

Making a thourogh hazard assessment includes what 3 aspects regarding the hazard in question?

(MCE)

A
  • the material (health or fire hazards)
  • the container ( materials under pressure?)
  • the environment (any people or property involved)
7
Q

This can determine how a product will move once released from its container and what means first responders can use to control this spread.

A

Hazardous material’s Physical state

8
Q

However, non-pressurized containers with liquids or solids may act like pressurized containers when subjects to – or –.

A

Heating

Chemical stress

9
Q

Assessing the – determines what may be exposed to a released hazardous
Material and the means by which first responders can protect these EXPOSURES

A

Environment

10
Q

Hazardous materials that become airborne, whether dust, gas , vapor, or mist, may require to control the vapor with:

A

Fog streams

11
Q

What are the 3 stages of a hazardous materials incident? (Container release)

A

Containers that have released their contents

Containers with an ongoing release

Containers that have not released their content (but have the potential to do so)

12
Q

When is aggressive action on part of first reponders necessary?

“Containing a hazardous material”

A

If the material is moving to an area where it may cause additional harm. (Slopes hard surface)

13
Q

Containers that have released their contents:

In most circumstances it is probably better to —until the first responders can contact someone who can provide advise on how best to proceed.

A

Stay away

14
Q

Stages of hazardous containers:

Incidents that involve containers — present responders with some significant threats.

A

With an ongoing release

15
Q

Also the rate at which the gas is released will depend upon this —.

A

Internal pressure

Storage Pressure determines volume of gas inside container

16
Q

Responders should never forget the limits of their structural PPE related to — exposure.

A

Chemical

17
Q

Stages of hazardous containers:

These containers may be stressed by heat, chemical reactions, or physical damage.

A

Containers that have not released their contents

-these containers should be evaluated to determine if there is any stress that could result in their release.

18
Q

If responders cannot safely eliminate any ongoing stress applied to a container, — of areas that potentially could be affected by a release may be necessary.

A

Evacuation

Safe eliminations of stress include:

  • Extinguishing nearby fire
  • Cooling a heated container with water

DO NOT relocate containers!

19
Q

A first responder should remember that while on scene of an incident he should view himself as a representative of a —.

A

Government agency.

Not a friend of the victim

20
Q

What is often worse than a delay in patient care?

A

Providing the wrong patient care

21
Q

What is one of the best recommendations for solving dispatch problems?

A

Ensure that individuals responsible for receiving requests for emergency assistance know to ask appropriate questions.

22
Q

Understanding the nature of an event provides first responders with considerable information on which to base their initial actions and also:

A

Ensures an adequate and appropriate response of apparatus and personnel.

23
Q

Every MVA has the potential for what?

A

A release of a dangerous chemical from containers that may be in the trunk of a car, back of a pick up,…

24
Q

A first responders decision on what actions to take regarding the stage of an incident (containers) should always be based on what?

A

Whether those actions will really make a difference.

25
Q

When relaying chemical names, whether during dispatch or during communications with others involved in the response such as hospitals, the message should be accomplished by:

A

Spelling the name

26
Q

A first responder must never forget that whatever he is doing while parked in top of the incident can almost certainly be done:

A

Several hundred feet back

27
Q

Knowing that hazardous materials are usually safe unless released from their CONTAINERS, first responders can avoid becoming part of the problem by also:

A

Assessing the STAGE of an incident upon their arrival

28
Q

And assessment of the hazardous materials involved takes into consideration it’s:

A

Health effects and the potential for fire or explosion

29
Q

First responders who encounter a container that has not yet released its contents must:

A

Continuously evaluate the situation.

30
Q

Regardless of what first responders do or do not do, their decisions must be:

A

Defensible and based upon reliable information

31
Q

When relaying chemical names, whether during dispatch or during communications with others involved in the response such as hospitals, the message should be accomplished by SPELLING the name. This should preferably be done using some form of the:

A

Phonetic alphabet

32
Q

To avoid becoming part of the problem during an incident, the first responder must remember that there could always be a:

Vs

First responders can avoid becoming part of the problem during a hazardous materials incident by:

To avoid becoming part of the problem a first responder must consider:

A

Hazardous material involved.

Making a thourough hazard assessment.

That whenever he thinks he is too close, he probably is.

33
Q

*Assessing the ENVIRONMENT determines:

A

what may be exposed to a released hazardous material and the means by which first responders can protect exposures

34
Q

Containers that have not yet release their contents

What are first responders roles?

A

Decide whether they can safely eliminate a source of stress, such as extinguishing a nearby fire, or reducing the effects of stress, perhaps by cooling a heated container with water.

35
Q

Defensive Actions for first responders include

A

Protecting nearby persons property or the environment from the effects of a hazardous material. This could be done by containing the release from a safe distance while preventing exposures.
