6.5 Fittings
In cases where external cleaning of fittings (e.g., pres-
sure reducer, valve) becomes absolutely essential,
use only a clean cloth which should either be dry or
moistened with clean water.
Never immerse fittings in disinfectant or other fluids.
Just wipe over with disinfectant. Fluids must not get
into the pressure reducer. Otherwise explosions
might occur.
If in exceptional cases you have no alternative but to
disinfect by wiping, take particular care to prevent
any fluid getting into the pressure reducer.
In addition to the risk of explosion, there is also the
risk of disinfectant getting into the patient’s respira-
tory tract with the oxygen and leading to injury.
