How many steps does the transmitted load estimation process involve?
There are 3 steps: Step 1: From the scaled distance tables or formulae from which these are derived, determine pressure and impulse impinging on BlastWrap components, and calculate peak reflected pressures and impulses using applicable references, such as TM5-1300/NAVFAC P-397/AF88-22 “Structures to Protect Against the Effects of Accidental Explosions.” Step 2: From Step 1, determine if you need Impulse Mitigator layers, and/or multiple BlastWrap/Impulse Mitigator layers. Step 3: To determine BlastWrap requirements for repeated or multiple-blast environments, first estimate severity of “typical” explosion exposure. The number of layers should equal the number of moderate or stronger blasts, which must be mitigated. Weak blast environments cause little damage to BlastWrap; thus, BlastWrap can provide mitigation of successive explosions. Flammable fluid and dust explosions and fireballs remove the filler-confining skin, which may spill substantial amounts of mitigating material. The same
