BOOK 37 HAZARDOUS MATERIALS OPERATIONAL PLAN CHAPTER 4 FIRST RESPONDER OPERATIONS Flashcards
(131 cards)
Once the first responder has arrived on scene, one of the initial considerations must be to establish ______ for the incident.
Perimeters
These perimeters will designate the Initial ______ Zone, _______ boundaries and _____ _______ Area(s) for holding civilians and Fire Department personnel who have been exposed to a hazardous product.
Isolation zone
Evacuation boundaries
Safe refuge areas
The Initial Isolation Zone should be established using the recommendation of the Emergency Response Guidebook (ERG), taking the following factors into consideration:
Topography
Materials released
Wind/weather
the incident will dictate the location of the Initial Isolation Zone.
Topography
The location of the fire line tape designating the isolation area should be placed in an ____ or _____ location to ensure that initial actions are undertaken from a safe location.
Uphill or upwind
The physical and chemical properties of the material released will determine the size of the
Isolation zone
Upon arrival, the _____ ______ _____ ____ may either expand or reduce the Initial Isolation Zone to establish the Exclusion Zone.
Hazardous materials task force
should be established within the outer-most perimeter of the isolation area to contain those people who have been exposed.
Safe refuge area
Considerations En Route
- What is the location of the hazardous materials incident
- Is the site heavily populated
- Is the site near major street or freeway
- What is the current weather conditions
- What is the time of day
- Is it a significant historical date?
- What is the best approach route?
- What resources are responding?
According to the erg 2000 edition what is a distance within which all person should be considered for evacuation in all directions from the actual spill/leak source. It is a distance (radius)which defines a circle within which persons may be exposed to dangerous concentrations upwind of the source and may be exposed o life threatening concentrations downwind of the source
Initial isolation zone
Once on scene, place a short length of ____________ or other suitable material on the apparatus antennae and keep a close watch on wind direction.
Fire line tape
At any incident it is wise to ___________ and evaluate the scene before committing yourself or others. ________ provide the first responder with an opportunity to view the scene from a safe distance.
Stop short
Binoculars
is intended to limit the effect of hazardous materials on victims of exposure and prevent the spread of contaminants beyond the contaminated area.
Decontamination
Prior to initiating decontamination efforts, first responders should ______ patients by attempting to separate symptomatic from asymptomatic patients. This assessment will serve to identify those people who need immediate decontamination.
Triage
Emergency decontamination is also referred to as
Gross decon
is the expansion of the Emergency Decontamination process to accommodate large numbers of contaminated people.
Mass decontamination
follows Emergency Decon, is a process that includes scrubbing with soap or other solution and thorough rinsing.
Secondary decontamination
follows Emergency Decon, is a process that includes scrubbing with soap or other solution and thorough rinsing.
Technical decontamination
Technical Decontamination is intended for all _______ _________ and is ideally performed in a separate area, away from the incident victims.
Emergency responders
involves moving the victim from the hazardous atmosphere, and may involve oxygen therapy.
Respiratory decontamination
The best personal protective equipment for first responders engaged in decontamination is the _______ ensemble provided for every position on each fire suppression company and rescue ambulance.
Level B
What kind of stream patter should be used during emergency decon and for how long
High volume fog spray
2-3 mins per person
First-arriving companies can initiate Mass Decontamination by using fog and spray streams with:
Ladder pipes
* Portable monitors
* Wagon batteries
* Discharge gates
* Hand lines
Patients who have received emergency decontamination, or who remain or become symptomatic while in Safe Refuge, will receive
Secondary decontamination
