CHEM-BIO Escape Mask

A personal emergency device for short-term respiratory protection during escape from situations involving hazardous and toxic air.

Features

  • Pocket-size.
  • Dons within seconds.
  • No adjustments straps.
  • One size fits all.
  • Strong, fire-resistant, elastic rubber hood, protects the entire head and seals comfortably at the neck.
  • High-efficiency, electrostatic particle filter, with extremely low pressure-drop to allow easy breathing.
  • Layers of activated charcoal with special impregnation to absorb toxic gases.
  • One-way exhalation valve and rubber ring (patent pending) enables rapid exhalation and improves the physiological conditions for the user, preventing built-up of heat or vapor inside the mask.
  • Large visor, made of flame-retardant transparent film, allows a wide field of view.
  • Training model available.
  • Available in two colors: yellow and black.
