    Q5: How do escape masks work?

    Escape masks function by filtering contaminated air to remove harmful particles, gases, and vapors, allowing the wearer to breathe safely during evacuation. The exact mechanism depends on the technology used:

    • Mechanical Filtration: High-efficiency particulate air (HEPA) filters trap smoke, dust, and ash particles as small as 0.3 microns.
    • Chemical Absorption: Activated carbon or specialized sorbent materials adsorb toxic gases like carbon monoxide, chlorine, and sulfur dioxide.
    • Thermal Protection: Fire-resistant hoods protect the head and neck from radiant heat during fire evacuations.
    • Sealed Fit: A tight seal around the face or head prevents unfiltered air from entering, ensuring all inhaled air passes through the filter.

    Most modern escape masks are “passive,” meaning they require no power source or compressed air. Instead, they rely on the user’s natural breathing to pull air through the filter. This makes them simple, reliable, and easy to deploy in panic situations.

    It's important to note that escape masks are not designed for prolonged exposure or oxygen-deficient environments—they are strictly for escape, not rescue or extended work in hazardous zones.
