power monitor and make routine vibration monitoring
checks.
In dirty or dusty environments, make regular checks
and remove dirt from areas around close
clearances, bearing housings and motors.
1.6.4.4 Preventing the build-up of explosive
mixtures
ENSURE THE PUMP IS PROPERLY FILLED
AND VENTED AND DOES NOT RUN DRY
Ensure the pump and relevant suction and
discharge pipeline system is totally filled with liquid
at all times during the pump operation, so that an
explosive atmosphere is prevented.
In addition it is essential to make sure that seal
chambers, auxiliary shaft seal systems and any
heating and cooling systems are properly filled.
If the operation of the system cannot avoid this
condition, fit an appropriate dry run protection device
(for example liquid detection or a power monitor).
To avoid potential hazards from fugitive emissions of
vapour or gas to atmosphere the surrounding area
must be well ventilated.
1.6.4.5 Preventing sparks
To prevent a potential hazard from mechanical
contact, the coupling guard must be non-sparking.
To avoid the potential hazard from random induced
current generating a spark, the baseplate must be
properly grounded.
Avoid electrostatic charge: do not rub non-metallic
surfaces with a dry cloth
; ensure cloth is damp.
The coupling must be selected to comply with
94/9/EC and correct alignment must be maintained.
1.6.4.6 Preventing leakage
The pump must only be used to handle liquids
for which it has been approved to have the correct
corrosion resistance.
Avoid entrapment of liquid in the pump and
associated piping due to closing of suction and
discharge valves, which could cause dangerous
excessive pressures to occur if there is heat input to
the liquid. This can occur if the pump is stationary or
running.
Bursting of liquid containing parts due to freezing
must be avoided by draining or protecting the pump
and ancillary systems.
Where there is the potential hazard of a loss of a
seal barrier fluid or external flush, the fluid must be
monitored.
If leakage of liquid to atmosphere can result in a
hazard, install a liquid detection device.
1.6.4.7 Maintenance to avoid the hazard
CORRECT MAINTENANCE IS REQUIRED
TO AVOID POTENTIAL HAZARDS WHICH GIVE A
RISK OF EXPLOSION
The
responsibility for compliance with
maintenance instructions is with the plant
operator.
To avoid potential explosion hazards during
maintenance, the tools, cleaning and painting
materials used must not give rise to sparking or
adversely affect the ambient conditions. Where
there is a risk from such tools or materials,
maintenance must be conducted in a safe area.
It is recommended that a maintenance plan and
schedule
is adopted. (See section 6
MAINTENANCE.)
