Chemical Mask - Smoke

chemical escape mask

A personal respiratory protective device with visor, hood and built-in filter for escape from fire. Protects against smoke and CO (Carbon Monoxide) inhalation. Complies with European Standard EN-403.

Features

Easy to use. 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.
Unique breathing device (patent pending), enables rapid exhalation and improves the physiological conditions for the user, limiting build-up of heat or vapor inside the mask.
A filtration unit containing low pressure electrostatic particle filter, impregnated charcoal cloth layers to absorb toxic gases and catalyst for Carbon Monoxide Oxidation.
