Determinations concerning fitness for purpose and particular matters or application of the Practice to particular project or engineering situations should not be made solely on information contained in these materials. The use of trade names from time to time should not be viewed as an expression of preference but rather recognized as normal usage in the trade. Other brands having the same specifications are equally correct and may be substituted for those named. All Practices or guidelines are intended to be consistent with applicable laws and regulations including OSHA requirements. To the extent these Practices or guidelines should conflict with OSHA or other applicable laws or regulations, such laws or regulations must be followed. Consult an appropriate professional before applying or acting on any material contained in or suggested by the Practice.

This Practice is subject to revision at any time by the responsible Function Team and will be reviewed every 5 years. This Practice will be revised, reaffirmed, or withdrawn. Information on whether this Practice has been revised may be found at www.pip.org.

Requirements 5.1

Design 5.1.1

Blast resistant doors shall be designed for the dynamic loads provided in the PIP STC01018 Appendix A Data Sheet. The performance category for the blast resistant doors shall be as specified in the PIP STC01018 Appendix A Data Sheet, Section A-3, “Blast Door Requirements.” The response limits and other requirements shall be as given in PIP STC01018, Table 9. 5.1.1.1 After an explosion, the doors are to be manually operable from the inside and outside to allow egress from the building. Unless otherwise specified in the contract documents, all doors are to open to the outside. 5.1.1.2 Each door system shall consist of a door, frame, hinges, latches, pins, and associated hardware. The doorframes shall be attached to subframes that are embedded into the surrounding concrete walls or attached to other structural wall material. 5.1.1.3 The subframes shall be installed by the contractor in accordance with the drawings furnished by the door manufacturer. The intent of providing separate subframes and frames is to allow construction of the building to proceed during fabrication of the blast doors. The connection of the subframe to the frame shall maintain structural integrity throughout all response to the applied load. Design of this connection is the responsibility of the door manufacturer. The installation and maintenance of the structural integrity of the subframe installation during construction is the responsibility of the contractor/installer. 5.1.1.4 Dynamic elastic-plastic design techniques shall be used. Static, elastic analysis is not acceptable. The entire pressure-time history must be included in the response calculations. 5.1.1.5 Increases in material strengths that are due to strain rate effects shall be considered. 5.1.1.6 The door system shall be designed to resist rebound. Maximum rebound forces shall be identified and factored into the system design by the door manufacturer. 5.1.1.7 The door system shall be designed to withstand the applied blast loading one time only. It is not necessary to design the door to be reusable for a second explosion load; however, the doors shall remain operational following dynamic response to the blast load.

5.2

Manufacturer 5.2.1

Page 6 of 9

Subject to compliance with requirements for blast resistant doors, all components shall be designed and furnished by one (1) manufacturer and shall be factory assembled, completely operable, and shipped as a unit.
