holes or other damages of more

To prepare the oxygen self-rescuer for use, mount the shoulder strap

the back plate of the housing

straps into the adjusting buckles
and pull the ends of the shoulder
straps as far as possible (2).

Using the Oxygen Self-Rescuer

— Open the oxygen self-rescuer only in case of emergency.
If opened prematurely, the humidity of the ambient air could
penetrate the open oxygen self-rescuer and impair its function.
— Inspect the oxygen self-rescuer daily.
— Use the oxygen self-rescuer only once.
— To avoid risk of fire, make sure that no flammable materials
(petrol, grease, solvents etc.) can get into the oxygen self-rescuer
before or during operation.
There is also danger of ignition if the oxygen-releasing chemicals
come into contact with combustible substances such as coal
when the oxygen self-rescuer is damaged.
Opened units are classified as used and it is not allowed to store
them. They have to be disposed of (see "Disposal" on page 12).
For routine training purposes, use the training unit
