drill a square rectangular hole(850mm*300mm) on a blast resistant wall of instrument cabinet room

(OP)
Dear engineers:

I received an engineering deviation recently, it's planning to drill a hole on the balst resistant wall of instrument cabinet room

because the design institution forgot to design instrument rack and cable trays.

My question is: is this kind of hole can influence the integrity of the wall for the explosion resistant capacity? If so, are there

any other options to improve it? thank you!

Youth is not a time of life, it's a state of mind.

RE: drill a square rectangular hole(850mm*300mm) on a blast resistant wall of instrument cabinet room

Sorry for late reply.

Obviously, with a 0.3m x 0.85m "hole" (0.255 m2 area), the blast resistant wall is not going to be blast resistant anymore. As a matter of fact, this opening will act as a funnel for destructive blast energy generated by an explosion.

Without knowing more details, it is hard to give any meaningful recommendation.
Except one maybe - in the future avoid designers who "forget" things like instrument racks and cable trays. Happy New Year.
