What is the service life of an EEBD?

• A. 5 years
• B. 20 years
• C. 15 years
• D. 10 years

Answer: (C)

EEBDs have a finite service life because the materials inside—like seals and gaskets—and even the stored air can age over time, reducing reliability. The service life is the period during which the device is expected to perform as intended when stored correctly. For EEBDs, manufacturers typically specify about 15 years from the date of manufacture. That’s why 15 years is the best answer. Numbers like 5, 10, or 20 years aren’t the standard service life for these devices, even though interpretations can vary by model or regulation. The important point is that the device isn’t considered serviceable indefinitely; it should be replaced or recertified after its stated lifespan to ensure it will deliver reliable protection in an emergency.
