stored in magazines provided for that purpose. Blasting agents may

be stored in van-type trailers, provided they are well-ventilated,

kept clean and free of extraneous material that could create a fire

hazard;

2. Separate magazines shall be provided for the storage of

detonators and for explosives;

3. Detonators shall not be stored in the same magazine with

explosives or blasting agents;

4. Blasting agents, safety fuse or detonating cord may be

stored with explosives, but blasting agents must be kept physically

separated from the fuse, detonating cord and explosives;

5. Magazines shall be:

a. located in accordance with the current American Table

of Distances for Storage of Explosives,

b. detached structures located away from power lines,

fuel storage area and other possible sources of fire,

c. constructed substantially of noncombustible material

or covered with fire-resistant material,

d. reasonably bullet-resistant,

e. electrically bonded and grounded if constructed of

metal,

f. made of nonsparking materials on the inside, including

floors,

g. provided with adequate and effectively screened

ventilation openings near the floor and ceiling,

h. kept securely locked when unattended,

i. posted with suitable danger signs so located that a

bullet passing through the face of a sign will not

strike the magazine,
