Do all internal surfaces of a room or container need BlastWrap coverage?
You should cover the maximum surface area possible without interfering with the use of the confined space. You do not need 100% coverage, however: gaps for vents, utilities, wiring, or complex geometries will have little adverse impact on BlastWrap mitigation. Required coverage is more (at least 80%) for smaller containers than it is for large rooms or compartments. If explosives (including flammable dusts and mists) are likely to be dispersed through most of the space, then BlastWrap coverage should exceed 90%. If the location of explosions can be predicted within a large space, BlastWrap linings should cover at least 90% of the surface area (including roofs) within 2 meters (6 feet) of the potential explosion site (or vessel confining flammable fluids).
