If the operation of the system can not avoid this
condition it is recommended that you fit an
appropriate dry run protection device (for example
liquid detection or a power monitor).
To avoid potential hazards from fugitive emissions of
vapor 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 for
Category 2.
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 the cloth is
damp.
The coupling must be selected to comply with
94/9/EC and correct alignment must be maintained.
Additional requirements for pumps on non-
metallic baseplates
When metallic components are fitted on a non-
metallic baseplate they must be individually earthed.
1.6.4.6 Preventing leakage
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 auxiliary 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, the installation of a liquid detection device is
recommended.
1.6.4.7 Maintenance of the centrifugal pump to
avoid a 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.)
