SomNandi Industries manufactures blast resistant barriers tested from 0.3 to 2.7 bar overpressure, rated to the CPNI C15 anti-terrorist TNT blast standard, and resistant to hydrocarbon fire and gas explosion conditions, for chemical plants, oil and gas facilities, airports, and military installations. A blast resistant barrier, also called a blast wall or explosion resistant barrier, is a protective structure engineered to shield buildings, equipment, or personnel from explosion overpressure, flying debris, and secondary fire risk. This page is written for safety engineers, EPC contractors, and facility managers at industrial, defense, and infrastructure sites who need a blast resistant barriers manufacturer working to tested, certified standards, not a generic concrete or steel wall relabeled as blast protection.
