Breaching Technologies Strip_Lock Explosive Breaching Door - Manual (Page 11)

Explosive Placement
Placement of the pushing charge is on the reinforced
plate on the front of the door. The charge should be
attached to the door utilizing double-sided tape,
breachers paste or similar method. Water bags are
commonly placed over the charge to enhance the
pushing effect.
Care should be exercised as to not allow the charge to
overlap on to the doorframe or associated structure.
This will only apply meaningless forces into the
doorframe. Over time this will shorten the life of the
product.
Remember that when a detonation occurs, the
material used to push the door open is deformed and
fragments at a very high velocity. It is therefore
recommended that shields, ballistic vests, ear and eye
protection always be used. If shields are not practical
then the door should be placed in such a manner or
location to allow trainees to have sufficient cover to
protect them from the blast and accompanying
fragmentation that will be propelled through the air in
all directions.
