International SPACE STATION/Damage Control/FIRE and Depressurization Hazards

Description of Driving Event:

Improvements needed to locate fires and leaks, as well as improvements needed in procedures and tools to control these hazards.

Lesson(s) Learned:

While the basic framework for system engineering of damage detection, assessment, and control has been established, work remains to be accomplished to reduce vulnerability to the hazards of FIRE and pressure leaks.


Examine procedures, tools and instrumentation to locate fires and penetrations more rapidly, especially those occurring behind equipment racks. Improve the ability of the crew to communicate with each other while dealing with emergencies. Create, qualify, and stock kits for rapid short- and long-term repair of penetrations. Develop a procedure to be used in the event of combined depressurization and FIRE.

Evidence of Recurrence Control Effectiveness:

A prototype, hand held, Ultra Sonic leak detector has been deployed to ISS for evaluation. This detector allows more rapid identification of leaks in pressurized elements. It has been utilized on-orbit to locate minor leaks in components.

A wireless intercom headset has been proposed. Implementation of this capability will be evaluated as part of the Pre-Planned Program Improvement (P3I) Process.

The three-phased development plan of joint U.S. and Russian Leak Detection and Repair Team includes both short-term and long-term repair of penetrations.

NASA will evaluate the adequacy of current FIRE and depressurization procedures to handle a combined FIRE and depressurization event.
