What are three ways to determine if an ammo item is It is a cloth-covered component marked "INERT"
inert?
It is drilled with holes, and the word "EMPTY" is stamped on it
It is small arms ammunition on public display with "INERT" attached on a plate
What are two exceptions to the requirement to drilling Empty or inert ammo used in loading drills
holes into inert ammo?
Empty or inert ammo whose use would be reduced by the holes

chemicals produce extreme heat and are difficult to TH
extinguish when burning? HC
Using the Chemical Group Job Aid, select two types of Fire resistant gloves, coveralls, and safety face shields
PPE/Special Equipment for Chemical Group C
Water barrels available to submerge leaking WP ammunition
Which distance is intended to prevent propagation ILD
between two operating buildings containing explosives?
Why are there divisions within Class 1? To identify the specific hazard posed
Magazine A contains HC/D 1.1. Magazine B contains HC/D 1.4
1.4. Which HC/D requires the smallest safe separation
distance?
The maximum NEW this magazine is permitted to hold is 4 pallets
12,500 lbs of HC/D 1.1. It currently contains 11,000 lbs.
Using the Yellow Book, how many pallets of the
ammunition listed below can be placed in the facility?
The RM process works to prevent what three hazards? Illness
Injury
Death
There are several potential hazards in the banding Determine how likely it would be to happen
operation. What two methods do you use to assess a
hazard that has been identified during the risk Determine how severe the outcome would be
management (RM) process?
SOPs are written with the cardinal rule in mind. It states Minimum number of people
that operations must expose:
Minimum amount of time
Minimum quantity of explosives
SOPs exist to: Protect
Inform
Guide you through your duties
Which four statements about SOPs are true? SOPs identify potentially hazardous items and conditions
SOPs must be available in work areas
Workers must read SOPs, or supervisors must read SOPs to workers, before
performing an operation
SOPs provide safety guidelines for each operation
