The analyzer may only be energized with permission of the works
manager or his proxy. Permission may only be given when it has been
determined that an explosive atmosphere is not present or when the
necessary protective measures against explosion hazards have been
taken (“hot permit”) during the time that the system is energized.
The analyzer enclosure may not be opened when energized if an explo-
sive atmosphere is present.
For normal analyzer operation, the purge system must on.
