Temporary Buildings Blast Resistant Modules Equipment Overview Byrne’s rental fleet of Blast Resistant Modules (BRMs) are structurally built to resist blast loads of 5psi, 8psi and 10psi. BRMs can be used in the most hazardous area of the upstream, midstream and downstream sectors of the Oil and Gas industry. With a high specification standards of build and safety, the modular units can protect personnel and assets. Byrne’s BRMs are built in compliance with industry recognised standards for hazardous area operation. The BRMs are a customisable modular space that can meet with the varying project specific needs and requirements of customers.
