What is the definition of a biological agent?
A biological agent or product is a microorganism or microorganism product (toxin) which can cause disease in man plants or animals and which can also cause deterioration of materials
What is the definition of microorganism?
A minute living organism too small to be seen with the unaided eye
What is the definition of a parasite?
A plant or animal living on all within another living organism or host at whose expense it is maintained
What is the definition of a pathogen?
A disease producing microorganism
What is the definition of a toxin?
Generally any poisonous substance or derivative of a microorganism of either vegetable or animal origin these may also be synthetically produced by man
What is the definition of virulence?
Different strains of the same organism may produce disease of different severity the more virulent the strain the more acute or severe the effects
What’s the definition of incubation period?
The incubation period is the time interval between penetration of the sufficient infective organisms into the body and the appearance of disease this is not normally less than 24 hours
What is the definition of a vector?
An intermediate host usually an insect or animal which carries the pathogen for one host to another
What is the definition of viable
Capable of living growing and developing
What are the 4 methods of delivery?

What is the general information and characteristics of anthrax?
Spread by bacteria that transforms into spores that in turn infect anything they come into contact with. Infection can attack the lungs to produce pneumonia and the skin to produce a localised reaction when skin turns black and dies.
What are the symptoms of anthrax?
Itchy skin High-temperature Severe cough Swelling to the throat Difficulty in breathing Internal and external skin tissue damage
What is the rate of action of anthrax?
The initial symptoms can be seen within 1 to 7 days
What are the protective timings for the NBC suit:
Thickened blister agent
Gross liquid contamination
Vapour Hazard only
Normal wear and tear
Thickened blister agent
6hrs
Gross liquid contamination
24hrs
Vapour Hazard only
24hrs+

28 days
What are the canister timings for all nerve and blister agent (except CX)?
3 hours
What are the canister timings for all other agents plus CX (except CK, CG)?
30 minutes
What are the canister timings for CK and CG?
15 minutes
What is the shelf life of a canister once un-wrapped?
4 months from unwrapping
What is the protection life of NBC gloves outer against gross liquid contamination?
3 hour
What is the protection time of NBC gloves outer if decontaminated within 15 minutes of initial contamination?
24 hours
How long will the overboots give protection against gross liquid contamination?
24 hours
What is the purpose of the splash suit?
To extend the life of an NBC suit
Where could a splash suit be utilised?
Vehicle and equipment decontamination
What must be used in conjunction with the BC suit?
SCBA
What is the maximum and minimum operating pressure for the SCBA?
300 and 240 bar
How many litres of air does the SCBA hold?
2400ltr
What is the approximate duration use of SCBA?
60 minutes
When the whistle is operated on the SCBA how much time and how much pressure is remaining?
12 minutes and 60 bar
What is the un-charged weight of SCBA in steel and Kevlar?
Steel 17 kg
Kevlar 8 kg
When calculating the endurance of the SCBA, what are the calculations?
Breathing rate of 40 ltr per minute
3/2/4
300bar x 2 cylinders x 4 ltr = 2400ltr
Duration 2400 ltr / 40 ltr/min = 60mins Alarm whistles at 60 bar 60 bar x 2 cylinders x 4 ltr = 480mins 480 / 40 = 12mins (to return to ICP) 60mins - 12mins = 48mins Planning time 40mins
What are the 5 checks for SCBA?
Does it work How much air Does it leak Does the mask seal Does the whistle work
When testing the SCBA for leaks what is it that we’re looking for?
With the air turned off looking to lose no less than 10 bars of pressure in 60 seconds
