SAFETY INSTRUCTIONS WHILE MAINTENANCE & SERVICING
Do not attempt repairs of the pump or its accessories which you do not know.
Use proper tools.
Before attempting any maintenance on a pump particularly if it has been
handling any form of hazardous liquid, it should be ensured that the unit is
safe to work on. The pump must be flushed thoroughly with suitable cleaner
to purge away any of the product left in the pump components.
This should be carried out by the plant operator and a certificate of cleanliness
obtained before starting work. To avoid any risk to health it is also advisable
to wear protective clothing as recommended by the site safety officer
especially when removing old packing, which may be contaminated.
Isolate the equipment before any maintenance work is done. Switch off the
main supply, remove fuses, apply lockouts where applicable and affix suitable
isolation warning signs to prevent inadvertent reconnection. In order to avoid
the possibility of maintenance personnel inhaling dangerous fumes or vapours,
shift to a suitable location/maintenance area by removal of bearing housing
and shaft assembly.
Check and ensure that the pump operates at below the maximum working
pressure specified in the manual or on the pump name plate and before
maintenance, ensure that the pump is drained down.
