Gathering Missing Info on Blast Projects Saves Time.

Many blast project specs do not provide enough information to come up with the equivalent 3-second blast design pressure from ASTM F2248. Glazing contractors can save time by requesting the following information in advance.
 
  • Explosive Weight - (Typically for most projects explosive weight II)
  • Standoff Distance - (For most projects it is the Conventional Construction Stand Off = 82 ft)
  • Level of Protection - (Typically Low Level of Protection)
 
This criteria is usually determined during the design phase of a project by the using agency or the design team.
