Flashcards in Questions From Pritchard and Freeman Deck (45):
Where would you find Biohazards
Veterinary and pharmaceutical research
Food research establishments
What would you do if you suspect any biological hazard?
IC assertions whether there is a biohazard involved, checks MDT for premises information.
“BIOHAZARD SUSPECTED” message to control.
BA and GTS
Unprotected personnel and appliances to be upwind of the incident.
Avoid using large quantities of water
Who would provide additional help or support at an incident
Scientific advice service
Where would you typically find asbestos
Ceiling and floor tiles
Insulation for boilers
Gaskets in heating installations
Cement asbestos in sheeting
If asbestos is suspected, what level of protection is required?
The IC will need to carry out a risk assessment to determine the level of PPE.
In non-fire situations, gas tight suits should be considered.
How does asbestos affect the body?
Chronic, Lung disease
What is the minimum distance between the hot zone and the cold/decontamination zone?
What information can be found on the EAC?
The EAC code (Emergency Action Code) notifies emergency services of the initial actions to be taken at an incident involving hazardous materials.
It tells you
1-what extinguishing media to use
2-what level of PPE
3-whether to contain or dilute the run off
4-whether it is a public safety hazard or not.
What are the three steps of approaching CBRN (terrorist threat)
Step 1-single casualty- approach using normal operating procedures
Step 2- two casualties -Approach with caution, consider all possibilities, do not discount anything, report arrival and update to Brigade Control.
Step 3- three casualties - DO NOT go to the scene. Go to predetermined RVP, await further instructions
What are the signs of a CBRN incident?
Dead or distressed people or animals
Multiple examples of skin or breathing irritation
Presence of hazardous materials
Unexplained smells or taste
Unexplained oily droplets on water
Withered plantlife on exterior of building or incident.
What are the three steps for approaching a CBRN incident?
Response - first 3 hours
Recovery - following 3 hours
Restoration - on conclusion of the incident
What does the pneumonic METHANE stand for?
It’s to aide correct messages to control.
Major incident? (Standby or declare)
Type of incident
Access and egress
Number of casualties
What are the LFB generic key roles of a CBRN event
To save life
To prevent/fight fire
Manage hazardous materials and protect the environment
Ensure the health and safety of all first responders
Safety management within the inner cordon
What unit is radiation measured in?
Sieverts (Sv) HOWEVER, this unit is too large to accurately measure radiation for LFB practical use.
We measure in millisieverts and microsieverts
What is the emergency exposure limit in the space of 12 months
20 mSv (millisieverts) per year with an additional dose of 13 mSv (millisieverts) for women
What is the time distance shielding?
These are methods of controlling the amount of exposure to radiation.
MINIMUM TIME- MAXIMUM DISTANCE - MAXIMUM SHIELDING
-The less time exposed to a radioactive source, the smaller the dose will be.
-The intensity of radiation reduces the further away you are from the source.
-Shielding is the prevention of penetration by using barriers (such as lead, steel and concrete).
Where is radiation found?
Research and education establishments
What can indicate the first signs of radiation?
Prior knowledge or intelligence
Radioactivity warning placard
Caller stating that radioactive materials are present
EPD (electronic personal dosemeter) actuating
Survey meter showing a dose rate above background
Terrorist or malicious attacks
Tue or false.
If radiation is suspected, use a jet.
False, spray or fog
Describe the EPD alarm sound
Initial dose alarm: intermittent, double fast tone
Dose constraint alarm: continuous slow dual tone for 2minutes, followed by a beep every 30 seconds
Exceptional dose alarm: continuous single tone for 10 minutes, followed by a beep every 30 seconds
When would you wet decontaminate?
When a firefighter/material/casualty has been subjected to caustic or biohazards or radiological hazards/material
When decontaminating, what would HMEPO need to consider?
The type and scale of the incident
Weather and wind direction
Slope of ground
Ease of access for oncoming vehicles
How can exposure to HAZMATs occur?
Chemical or heat burns
What are the different types of radiation
What colour is an acetylene cylinder?
What are the signs of cylinder damage?
Plastic labels or rings melted
Blackened or blistered paintwork
Supply hose pipes damaged
At what temperature does a steel cylinder lose its tensile strength?
At what temperature does an aluminium cylinder lose its tensile strength?
What is the distance that a steel cylinder may be thrown upon failure?
What is the most reliable way of identifying an acetylene cylinder?
The paper label attached to the collar of the cylinder.
It will be painted maroon.
It MAY have a reflective strip.
Where might the location of premises storing cylinders be found?
On the ORD, available on the MDT
When there are indications of cylinders involved in an incident, where should appliances park?
Where it would be protected should a cylinder fail
What type of cylinder should be allowed to burn off before extinguishing the fire?
This prevents a build up of unburnt gasses.
What cylinder information should be gathered?
Amount of cylinders involved
Acetylene cylinders which have been heated to 300 degrees and have not failed are at risk of ..........
How long must a acetylene cylinder be cooled for?
1 hour minimum
How many times should the CAP be repeated in an hour?
What is the maximum voltage that Electrical gloves are resistant to?
At what voltage is low voltage classed?
Between 50 and 1000v AC
At what voltage is high voltage classed?
Greater than 1000v AC
What is the likely voltage supplied to domestic properties?
What is the likely voltage supplied to commercial properties?
What hazards must be considered when dealing with fires involving solar panels?
The weight of solar panels
List the pollution control heirarchy
Close to the source
On the surface
In the drainage system
On or in the water course
