Q

Secondary devices

A
  • Destructive devices to be activated after an initial attack and timed to injure emergency responders.
  • Emergency response planners prefer the term multiple devices because it is more likely to make first responders aware of and prepared for the possibility of more than one destructive event following the first.

Q

Types of chemical incidents and whether it is primary or secondary harm

A
  • Thermal harm is secondary harm
  • Asphyxia is secondary harm because some chemical reactions may deplete oxygen or create gases
  • Chemical harms are primary harms and include wide variety of effects such as corrosivity and reactivity
  • Mechanical harm is a secondary harm. Must be taken into consideration because corrosive chemicals can weaken structural elements
  • Psychological harm is secondary harm because many individuals will react emotionally to a possible chemical exposure.

Q

Q

Common infection routes for biological infection

A
  • Vector (a disease-carrying organism)
  • Jagged glass or metal
  • Syringes
  • High pressure devices
26
Q

Degree of infection is based on what?

A
  • Rate of breathing

- Depth breathing

27
Q

Contamination

A

-Contact with or presence of a material (contaminant) that is present where it does not belong and is somehow harmful to persons, animals, or the environment

28
Q

Things that can be contaminated

A
  • Hard and soft tissues
  • Skin and hair
  • Clothing
29
Q

Exposure versus contamination

A
  • Exposure occurs when a substance is taken into the body through one of the routes of exposure
  • Contamination occurs when a substance clings to surface areas of the body or clothing
30
Q

Permeation

A

-The movement of a substance through a surface or, on a molecular level, through intact material; penetration, or spreading

31
Q

The types of harm that can result from biological incident primary and secondary

A
  • Chemical harm is secondary hazard
  • Etiological harm is a primary type of harm
  • Mechanical harm is a possible secondary hazard where explosives have been used to disperse the agent.
  • Psychological harm is a secondary harm
32
Q

The order of protection priorities

A
  • Self protection
  • Using the buddy system
  • Availability of rapid intervention teams
  • Civilian pretection
33
Q

Types of harm from radiological/nuclear incidents primary and secondary

A
  • Thermal harm is a primary harm
  • Radiological harm is a primary harm
  • Chemical harm is a secondary harm. Often over looked by responders who are concentrated on radiation effects
  • Mechanical harm is a primary harm
  • Psychological harm is secondary harm
34
Q

Something to keep in mind if the bombing was a suicide bombing

A

-Make sure to check all patients before transport. If a bomb is found evacuate all persons from the area

35
Q

Types of harm from explosive incidents primary and secondary

A
  • Thermal harm is a primary hazard
  • Asphyxia is a secondary harm because of possibility of dusty conditions
  • Chemical hazards created as a result of the explosive reaction
  • Mechanical harm is a primary harm from blast over pressure, shock waves, and fragmentation
  • Psychological harm is a secondary harm
36
Q

Preblast VS postblast

A
  • Preblast takes place after a written or verbal warning is received but before the explosion take place
  • Postblast takes place after at least one detonation has occured
37
Q

Dissemination

A
  • Spreading

- The most common means of dissemination is through the respiratory tract

38
Q

Weaponization

A

-Packaging or producing a material, such as a chemical, biological, or radiological agent, so it can be used as a weapon, for example by dissemination in a bomb detonation or as an aerosol sprayed over an area or introduced into ventilation systems

39
Q

Chemical agent considerations

A
  • Physical considerations is that known agents cover the whole range of physical properties
  • Volatility considerations is agents that have a low boiling point and high vapor pressure tend to be nonpersistent what is they will evaporate more readily
  • Chemical considerations is they are sufficiently stable to survive dissemination and transport to the site of their action
  • Toxicological considerations is that not all individuals of a species react the same way to a given amount of agent
40
Q

Classifications of chemical agents

A
  • Choking agents
  • Vesicating agents (blister agents) may not be apparent until hours after exposure
  • Cyanides formerly known as blood agents preventing the use of oxygen withing the body’s cells
  • Nerve agents inhibit enzymes that is critical to proper nerve transmission.
  • Riot control agents include irritating materials and tear flow increasers (lacrimators) (pepper spray, mace ect.)
41
Q

Biological agents

A
  • A bacterium is a small free living micro-organism meaning it can live outside of a host
  • Virus is an organism that requires a host cell inside which to live and reproduce.
  • Toxins are not living organisms. Is a poisonous chemical compound that is produced by or derived from a living organism
42
Q

Features of biological agents that influence their potential use as weapons

A
  • Infectivity
  • Virulence
  • Toxicity
  • Incubation period
  • Transmissibility
  • Lethality
  • Stability
43
Q

Infectivity

A

Q

Transmissibility

A

-Ability to spread

48
Q

Lethality

A

-Reflects the relative ease with an agent causes death in susceptible population

49
Q

Stability

A

-Viability of biological agent is affected by many environmental factors

A
  • The use of military nuclear weapon
  • The use of improvised nuclear devices

  • The sabatoge of a nuclear facility
55
Q

The three body systems that would be most severely affected by radiological materials

  • Blood forming system specifically bone marrow
  • The gastrointestinal system
  • The central nervous system
56
Q

Blast injury patterns

A
  • Lung injury
  • Ear injury
  • Abdominal injury
  • Brain injury

Q

Strategies

A

-Broad general plans designed to achieve desired outcomes

59
Q

Tactics

A

-Specific operational actions to accomplished assigned tasks

60
Q

Notification

A
  • Done by a dispatch center or an emergency operations center
  • The trigger event is the initial radio report made by an EMT
61
Q

Identification

A

-Identifying any indicators of a particular agent. take notice in anything that may be out of place or take notice in any hazardous materials

62
Q

Protection responsibility’s of an EMT

A
  • Make an initial scene size up to determine security threats
