10.2.9 Check hose lines
Even when adequately stored and subjected to permissible loads, hoses and hose lines are subject to
a natural ageing process. This limits their period of use.
The period of use of the hose lines must not exceed 6 years from the manufacturing
date stamped on them.
The period of use can be determined using available test and empirical values, taking into account the
conditions of use.
The operator of the system must ensure that hose lines are replaced at suitable intervals of
time, even if no defects which may affect their safe operation are identifiable on them.
Hose lines must be inspected for safe working condition by an expert before the plant is first
put into operation and thereafter at least once a year.
If during inspections faults are found, these must be rectified immediately or suitable
countermeasures taken.
