SERVICE, MAINTENANCE & DISPOSAL
6.1 Equipment Service
A number of external system based checks should be completed on a regular basis. These ‘routine
inspections’ must be carried out by suitably trained people with knowledge of the Gasguard CH4 Sensor
and the systems into which it is fitted. Routine inspections may take the form of either visual-only checks,
or visual and ‘hands-on’ checks.
6.1.1 Visual Only Inspections
A basic visual inspection focuses on looking at the installation for signs of physical damage, water or
dust ingress and the condition of cables and labels. This type of inspection may involve opening
cabinets to gain access to the Gasguard CH4 Sensor and other equipment. This level of inspection
may also include cleaning display windows that have become obscured by dirt.
Observations would typically be:
Check that equipment enclosures, cable trays, conduits, etc. are in good order with no physical
damage.
Check that sealed wall boxes are free from water and dust ingress internally. Door seals are in
good condition.
Check that connected cables are free from cuts, abrasions and obvious signs of damage. Cable
restraints are in good order and correctly fitted.
Check that labels on equipment, wall boxes and cables are present and in good condition
(especially certification labels).
Check that no modifications have been carried out to installed equipment.
6.1.2 Hands-On (Detailed) Inspections
A more detailed inspection would include all of the elements of a visual inspection, plus some checks
that cover the integrity of connections, fixtures and fittings.
In addition to basic visual observations, more detailed integrity checks would involve:
Verify that equipment housings, wall boxes and other mechanical fixtures are secured in place.
This includes terminal box lids, tightness of cable glands, integrity of wall-box mountings, security
of equipment fixing to walls/DIN rails etc.
Verify all electrical connections are secure with no loose screw terminals or DIN rail terminals not
fitted to rails etc.
