On August 11, 2020, RedGuard conducted an arena-style blast test on three of their modular blast-resistant buildings, with a 6,000-pound ammonium nitrate/fuel oil (ANFO) charge.
The test structures included:
An anchored 12 ft x 40 ft (3.6m x 12m) blast-resistant module (10 psi 200 ms) to model the typical installation of a custom, permanently installed BRM. Internally, the unit had typical finishes, a dividing wall, and a desk with a crash test dummy to simulate the human response.
An unanchored 12 ft x 40 ft (3.6m x 12m) BRM to model (8 psi 200 ms) the typical installation of a temporary rented unit.
An unanchored 8 ft x 20 ft (2.4m x 6m) module (8 psi 200 ms) with a window and intumescent coating to test coating adhesion during a blast and to test window performance during the blast.
A wooden trailer, similar to previously discussed Texas City buildings.
An old truck (the test lab provided it to observe the reaction).
