The door is designed to operate with typical operational weight “PUSHING TYPE”
charges only. The use of excessive charges will only lessen the life of the door and
increase the chance of injury.
Typical methods of backing material for the charges are polyethylene, rubber conveyor
belting and other plastic materials. Note that the chosen backing materials become
fragmented projectiles during the subsequent explosion.
BTI personnel have also utilized “water bag” type charges that generate acceptable
pushing type results.
Note that detonation cord is manufactured in many different
explosive weights. The military commonly utilizes 54 grains per
foot detonation cord. Always determine the total explosive
weight of any charge.
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
