What material is the mask of an Emergency Escape Breathing Device (EEBD) typically made from?

The mask of an Emergency Escape Breathing Device (EEBD) is typically made from silicone. Silicone is chosen for its excellent properties such as flexibility, durability, and resistance to temperatures and chemicals. The material can create a good seal around the face, ensuring that the user can breathe clean air while avoiding exposure to smoke, toxic gases, or other harmful substances during an emergency escape. This capacity for sealing, combined with its comfort and safety in use, makes silicone the most suitable material for the mask in these critical situations.

Other materials like polyester, Teflon, and rubber may not provide the same level of performance required in an emergency setting, which involves quick deployment and effective safeguarding against hazardous environments.
