Chemical Personal Escape Gas Masks

Model Number: DSA-43C

Overview

A personal emergency device for short-term respiratory protection during escape from an area of a chemical spill. Offers protection against organic gases and vapors with a boiling point higher than 65°C, certain inorganic gases and vapors, Sulfur Dioxide and other acidic gases and vapors, Ammonia and Ammonia derivatives.

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
