H-2 "Blast Resistant Door :
1. The performance category for the blast resistant doors shall be specified and the response limits and other requirements shall be as given in Table 9.
2. Doors, doorframes, and door hardware including hinges shall be designed for the performance criteria above and applied blast loads specified. The orientation of the door relative to the blast source(s) will determine the blast loads for which the door needs to be designed
3. Air locks shall be installed to maintain the required over-pressure inside the building. All outer doors shall be provided with automatic door closers.
4. No windows shall be provided in the outer doors; only small peepholes shall be provided to check, in the event of fire, that the area outside the door is safe to permit evacuation of the building.
5. The outer and inner doors shall have a good seal between door and frame to maintain the different pressures between the various rooms and the outside of the building.
6. There are no special requirements for blast resistance of inner doors of airlock systems.
7. Blast door Manufacturers shall provide calculations or test data to verify adequate blast resistance and door performance for the design load conditions.
8. Manually operated exit doors shall not exceed a maximum opening force of 25 N (5.6 pound force) (measured at the door handle) or shall meet the requirements of the local building codes for the maximum opening force. Power operated doors shall be used for exit doors that exceed the maximum opening force."
