You must remove an EEBD from service if there has been any what?

• A. Tampering
• B. Damage
• C. Theft
• D. Loss

Answer: (A)

Tampering with an EEBD directly compromises its reliability when you might need it in an emergency. An Emergency Escape Breathing Device is designed to provide a specific amount of breathable air and to operate in a precise way. If someone has tampered with it—altering seals, valves, gauges, labels, or any component—the device’s function can no longer be trusted. Even if the unit appears fine, hidden changes can render it unsafe or ineffective when used.

Because the integrity of safety equipment hinges on every part being original and unaltered, any sign of tampering means the equipment must be removed from service immediately. It should be tagged as non-serviceable and taken out of circulation until a qualified technician inspects, tests, and certifies it again. A replacement should be provided so personnel have a guaranteed working unit while the original is evaluated.

Note that other issues like damage, loss, or theft would also warrant removal, but tampering is the strongest trigger here because it specifically indicates that someone has interfered with the device’s safety mechanism, undermining its trustworthiness and readiness for use.
