Blast Resistant Buildings - ChemSAFE BRB
Blast Resistant Buildings (otherwise known as BRBs or Blast Resistant Modules) are multi-use facilities designed to provide protection from a petrochemical plant hazard such as a blast, toxic or flammable gas release. MineARC’s ChemSAFE BRBs are portable, pre-fabricated steel buildings that can also serve as work spaces, control rooms, or break rooms for general day-to-day use.
Fully customizable, ChemSAFE Blast Resistant Buildings can be produced in a short period of time and at a fraction of the cost of traditional ground-up construction. Installation consists of simply electricity and water (if needed).
Additionally, all units meet ASHRAE standards for fresh air quality for day-to-day use but can rapidly isolate outside air to become a fully sealed environment, automatically switching from a Class 2 Shelter to Class 1 for the highest level of protection. The integration of true shelter-in-place functionality in a portable building is a first in the industry and a means of fully complying with API RP 753 for buildings used for shelter-in-place.
MineARC understands the importance of blast protection for personnel working at a petrochemical facility. Third party testing has been performed by professional blast engineers, in accordance with ASCE: Design of Blast-Resistant Buildings in Petrochemical Facilities (2nd).
As part of their in-depth analysis, third-party blast engineers tested the performance of the MineARC Blast Resistant Building, taking into consideration the orientation of the unit with respect to the explosion source. Blasts that can impact either the long or short side of the structure, as well as both sides at an angle were tested.
The results of these studies show that MineARC’s blast resistant structure can withstand a long-duration, free-field blast load of up to 10psi for 200ms.

Blast Resistant Building – Front View
The strobe lighting, warning siren and reflective signage alert passers-by to the safe haven’s location, whilst the rotating door handles provide simple, straight forward access to the safety of the interior.
An additional feature of the ChemSAFE Utility Design Toxi Gas Shelter range is a fully pressurised vestibule, providing added protection against the ingress of smoke and other harmful toxins. Vestibules are available as either an internal or external feature of the safe haven. See further on for additional information.
