1.6.4.5 Preventing sparks
To prevent a potential hazard from
mechanical contact, the coupling guard must be
non-sparking and anti-static for Category 2.
To avoid the potential hazard from random
induced current generating a spark, the earth
contact on the base plate must be used.
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
2006/42/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, the installation of a liquid detection device
is recommended.
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.)
