6.5 Frequency of periodical operations
The device should be subjected to periodic inspection of its technical condition. It is the user's
responsibility. The user is obliged to supervise the installation on the ongoing basis, according to schedule
as below:
Frequency Description of activities
Daily Checking the device indications
Once in a quarter Checking the installation, mechanical defects
Checking operation of the detector (by exposing it to gas)
Table 5: Frequency of periodical operations
These tests are performed by a trained and qualified person. He / she is obliged to immediate notification of
the manufacturer of any observations and suspicions about the status of the device.
