How should you communicate with passengers or pilots when wearing the Protective Breathing Equipment hood?

• A. Speak clearly into the interphone through the hood.
• B. Shout loudly to attract attention from outside the hood.
• C. Use hand signals only, without using the interphone.
• D. Remove the hood briefly to speak.

Answer: (A)

Communicate through the interphone. When the Protective Breathing Equipment hood is on, the hood seals around your face and muffles your voice, making it hard for others to hear you. The interphone system is designed to transmit your message clearly to pilots or other crew even while you’re hooded, so you can convey instructions or information reliably. Shouting outside the hood isn’t dependable because the sound can be distorted or missed, and relying on hand signals alone isn’t sufficient for urgent or detailed messages to passengers or the flight deck. Removing the hood to talk would break your protective seal, exposing you to contaminants. Use the interphone, speak clearly, and wait for acknowledgment to ensure effective communication.
