Direction for Use and Care of Tube Helmets
Description
These helmets are the same as the smoke helmet already issued, except that stronger chemicals are added and a tube valve provided through which to breathe out. The tube valve makes the helmet cooler and saves chemicals from being affected by the breath. The wearer cannot breathe in through the tube valve; this is intended for breathing out only.
Directions for Use
Remove paper cap from mouthpiece of tube valve. Remove service cap. Pull helmet over head. Adjust so that goggles are over eyes. Tuck in skirt of helmet under coat collar and button coat so as to close in skirt of helmet. Hold the tube lightly in lips or teeth like stem of pipe, so as to be able to breathe in past it and out through it.
Breathe in through mouth and nose, using the air inside the helmet. Breathe out through tube only.
Directions for Care of Tube Helmet
1. Do not remove the helmet from its waterproof case except to use for protection against gas.
2. Never use your tube helmet for practice or drill. Special helmets are kept in each company for instruction only.
Should the goggles become misty during use they can be cleared by rubbing them gently against the forehead.
