Blast resistant station fixed barrier
A blast resistant barrier system includes a base, a support structure extending outward from the base, a protective barrier that is pivotally coupled with the support structure at a first point of the protective barrier, and a shear pin that is configured to couple a second point of the protective barrier to the support structure so as to constrain rotation of the protective barrier relative to the support structure. The shear pin is configured to shear upon a threshold amount of force being applied to a face of the protective barrier. Once the shear pin shears, the protective barrier is permitted to rotate relative to the support structure about the first point.
