Keep pace with today's improvements for PASS in the 2007 edition of NFPA 1982.

Personal alert safety systems (PASS) make it possible for emergency responders to signal for help if they get lost, disoriented, trapped, injured, or run out of breathing air while operating at an emergency. Provisions in NFPA 1982 address labeling, design, performance, testing, and certification for PASS that monitor an emergency responder's motion and automatically emit an audible alarm if the responder becomes incapacitated and allow the PASS to be manually activated if assistance is needed.

The 2007 edition important changes include:

• Rewritten design requirements that permit PASS to be other than a "single package", allowing the various components of PASS be located in or combined with other items of protective clothing. This enhances PASS performance and practicality.
• Strengthened performance and testing requirements for vibration resistance, impact, water ingress, and alarm signal strength and durability that better assure proper functioning after physical challenges and in high temperature environments

In addition, editorial and formatting changes were made to improve usability and readability.
