BREATHING APPARATUS

Malfunctioning while working 

Fault

Cause

Elimination methods

Notes

No readings 

on EMD

Battery failed 

Replace the battery 

in the non-explosive 

atmosphere

If you fail to eliminate the cause, 

switch to another breathing 

apparatus and leave the area that 

is not suitable for breathing

The electronic part of the device 

has malfunctioned

Switch to another 

breathing apparatus

Leave the environment that is not 

suitable for breathing

Breathing 

hose system 

of the 

breathing 

apparatus 

has leakage

Damage of the breathing hoses

Switch to another 

breathing apparatus

Leave the environment that is not 

suitable for breathing

Damage of the full-face mask

Switch to another 

breathing apparatus

Leave the environment that is not 

suitable for breathing

Increased 

breathing 

resistance

Pinching or kinking of the hose

Inspect the hose, 

eliminate the cause of 

possible pinching

If you fail to eliminate the cause, 

switch to another breathing 

apparatus and leave the area that 

is not suitable for breathing

Freezing of breathing valves to 

seats at low temperatures

Switch to another breathing 

apparatus. Leave the environment 

that is not suitable for breathing 

Frostbite of high pressure 

channels at low temperatures

Switch to another breathing 

apparatus. Leave the environment 

that is not suitable for breathing

Rapid loss of 

oxygen

Leaks in breathing hose system 

frequent operation of the 

demand valve with slight load

Switch to another breathing 

apparatus. Leave the environment 

that is not suitable for breathing

Malfunction of the oxygen 

distribution unit or demand valve 

or their connection points

Switch to another breathing 

apparatus. Leave the environment 

that is not suitable for breathing

Malfunction or disconnection of 

connectors in the oxygen supply 

system

Switch to another breathing 

apparatus. Leave the environment
