When does the unmasking drill take place and what the 4 parts?
Initiated by local commander on advice from higher authority via CBRN advisor/cell
1 LIQUID
(one colour detector paper to check all exposed surfaces for any chemical liquid, if found procedure is to stop check again after 30 mins min. until absence is reported, local commander the order test for vapour)
2 VAPOUR
(use vapour detection instrument, test area for trace of chemical vapour, check in areas where it may collect eg/trench,pits,shelters)
3 2 MAN SNIFF TEST
(Carefully controlled and done by 2 in front of local commander in upwind position, all clear can only be issued by higher authority after confirmation from CBRN advisor, when called individual sniff test done)
4 individual sniff test
(After all clear, if any time suspect chemical agent, remask and shout GAS GAS GAS)
outline both sniff tests
When does a suit need changing?
Soaked by fuel/oil
Torn
Been subjected to liquid chemical agent for more than:
- 6 hours in case of mustard droplets
- 24 hours in case of other agents
(Respirators worn throughout incase of vapour from contaminated clothing and gloves and outside of respirator cleaned incl. underside of chin)
What are the 2 categories of chemical agents and the 5 classes of chemical agents?
Lethal (kill)
Non lethal (incapacitation eg/pepper spray)
CLASSES

Aerosol generators
Spray equipment
What are the 4 types of lethal chemical agents?
NERVE (interfere with nervous system and disrupt bodily functions, cumulative effect, incapacitation/death)
BLOOD (affects bodily functions by preventing body tissue from using oxygen in blood, fast acting, lethal, non persistent, respirator can protect but must be on in 9s)
CHOKING (affects ability to breathe by attacking lungs and throat)
