When should an EEBD be removed from service?

The removal of an Emergency Escape Breathing Device (EEBD) from service is necessitated when the tamper seal is broken. This seal serves as an indicator that the device has not been used and remains in proper working condition. If the tamper seal is compromised, it suggests that the device may have been accessed or potentially used, which raises concerns about its reliability and functionality in an emergency situation. Ensuring that the tamper seal is intact is crucial for the safety of personnel relying on the EEBD during emergencies.

Other factors like signs of wear and tear or regular inspection findings can indicate maintenance needs, but they do not necessarily mandate immediate removal from service unless they directly affect the integrity or functionality of the EEBD. Similarly, while routine inspections are essential for overall equipment reliability, the critical criteria for removing an EEBD from service focuses primarily on the tamper seal's status.
