Q

When does the unmasking drill take place and what the 4 parts?

A

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)
