3 distinct hazmat operational modes

A

Offensive mode

Defensive mode

Nonintervention mode

1
Q

MOTEL

A

Magnitude- trying to keep incident as small or limited as possible

Occurrence- preventing future event from occurring by influencing the current events ex.cooling a tank

Timing-trying to change when an event happens and/or how long it lasts

Effects-trying to reduce the size and/or effects of an event

Location-trying to change where the next event occurs ex. Moving a tank truck to patch it to a less populated area

The IC’s hazmat strategic goals include

A

Rescue

Public protective actions

Spill control or confinement

Leak control or containment

Fire control

Transfer and recovery

6
Q

Strategy and tactics implemented by the IC can be…

A

Offensive

Defensive

Nonintervention

Usually uses a combo of tactics

7
Q

The IC should analyze and visualize events at the emergency scene in 3 phases..

Have IC’s approval for the entry/rescue ops

10
Q

Hazmat rescue problems fall into 3 general categories

A
  1. Searching for and relocating people who will be immediately exposed and harmed by the hazmat as it gets worse
  2. Rescuing victims who have been disoriented or disabled by the hazmat
  3. Planning and execution of technical rescue
11
Q

LNG in its liquid state is….

A

Methane!

12
Q

LNG has an expansion ratio of..

A

600:1

13
Q

LNG presents two primary hazards…

A
  1. Flammability

2. Liquid or vapour desperation

14
Q

3 general tactical LNG problems

A

Fire

Vapour cloud release

Cryogenic spill

15
Q

3 primary methods of liquid product transfer:

A

Gravity flow

Pump transfer

Pressure transfer

16
Q

Absorption

A

The process of “picking up” or absorbing a liquid hazmat to prevent enlargement of contaminated area

Movement of toxic ant into the circulatory system by oral, dermal, or inhalation

17
Q

Adsorption

A

Process of adhering to a surface, a common physical method of spill control and Decon

18
Q

Damming

A

A physical method of confinement by which barriers are constructed to reduce the quantity of liquid flowing into the environment
