Chapter 10 Flashcards
what are the factors that make up MOTEL in regard to
Magnitude Occurence Timing Effects Location
What are some examples of Strategic goals
- rescue
- PPA
- spill controll ( confinement)
- leak control
- fire control
recovery
what are the three modes of operations
- offensive
- defensive
- non-intervention
What factors must be considered by IC when considering an intervention.
- potential casualties and fatalities
- potential property damage or financial loss
- potential environmental damage
- potential disruption of the community
- political considerations
What are four examples of tactical operations that can be used to buy time?
- barriers– place a physical barrier
- distance– separate people from the hazmat
- time– reduce the duration of the release or rotate persons who are exposed
- techniques – specific tasks and procedures preformed by responders to stop the leak and control the problem
what are three general categories that rescue problems fall into
- searching for and relocating people who have been exposed to the hazmat
- rescuing victims who have been disoriented or disabled by the hazmat
- planning and executing technical rescue
what are three factors that can complicate a Technical rescue within a HAZMAT call?
- hazardous atmospheres
- hazardous work areas
- limited access areas
what is Absorption?
the physical process of absorbing or “ picking up” a liquid hazardous material.
- absorbants often swell as the material is picked up
-
What is adsorption?
- the chemical process in which a sorbate interacts with a solid sorbent surface. ( think of tape sticking and picking up ) vs a sponge
what is a physical method of confinment that is often a temporary measure until a more effective action can be taken?
COVERINg
Damming is what ?
a physical method of confinement by which barriers are constructed to prevent or reduce the amount of liquid flowing in an environment
what is an overflow dam vs. underflow dam?
overflow is used to trap sinking heavier than water materials behind the dam where and underflow is used to trap floating lighter than water material.
what Diking?
a physical method of confinement by which barriers are constructed to control liquids, sludge, or solids.
What is the chemical method of by which a water soluble solution is made safe by adding large volumes of water to the spill?
Dilution - not a linear progression and often takes very large volumes of water to make reduce the effectiveness of the material
what is the physical method of confinement by which barriers are constructed on ground or placed in a waterway to intentionally control the movement of the hazardous material into an area where it will pose less harm to the community and environment ?
Diversion
