Where would you find Biohazards
Laboratories Veterinary and pharmaceutical research Medical schools Commercial premises Food research establishments Hospitals
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 Restrict access Minimum personnel Unprotected personnel and appliances to be upwind of the incident. Consult HMEPO Avoid using large quantities of water
Who would provide additional help or support at an incident
HMEPO FRU Scientific advice service CBRN team
Where would you typically find asbestos
Ceiling and floor tiles Insulation for boilers Spray insulation Brake linings 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?
25m
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)
123PLUS 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) Exact location Type of incident Hazards Access and egress Number of casualties Emergency services.
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?
Hospitals Construction sites Research and education establishments Laboratories Naval vessels Marked vehicles
