EMERGENCY ESCAPE HOODS

CARRYING BAG
IMPORTANT FOR SAFETY
The chemical escape hood comes with a soft carrying
bag in a water resistant, strong and durable material.
The format is very compact, only approximately
21x12x11 cm /8.3x4.7x4.3 in.

It has a zipper, which is water proof, for easy opening.
In the rear, there is a pocket for filter date, name or a
safety card. The bag can be worn on a belt, carried over
the shoulder or round the waist. It also has brackets
for wall mount.

The bag is very important as it makes the hood easy to
bring, when working in risk environments

ESCAPE HOOD FILTERS
• Escape hoods use class 2 filters and gives the user a higher level of protection, or longer action time
• See the table for breakthrough times for filters in concentrations as high as 5000 ppm RESPIRATORY PROTECTION
