Chemical / Biological Personal Escape Hoods

Model Number: DSA-54C

Overview

A personal emergency device for short-term respiratory protection during escape from an area of low concentration of chemical or biological agents.

Features

• Pocket-size
• Dons within seconds. No adjustment straps
• One size fits all
• Strong, fire-resistant, elastic rubber hood, protects the entire head and seals comfortably at the neck
• Large visor, made of flame-retardant transparent film, allows a wide field of view
• 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
• A unique breathing device (patent pending) enables rapid exhalation and improves the physiological conditions for the user, preventing built-up of heat or vapor inside the mask
• Training model available
• Available in two colors: yellow and black
