1.6 Safety


1.6.1

Summary of safety markings

These User Instructions contain specific safety
markings where non-observance of an instruction would
cause hazards. The specific safety markings are:

This symbol indicates electrical safety

instructions where non-compliance will involve a high
risk to personal safety or the loss of life.

This symbol indicates safety instructions where

non-compliance would affect personal safety and could
result in loss of life.

This symbol indicates “hazardous and toxic fluid”

safety instructions where non-compliance would affect
personal safety and could result in loss of life.

This symbol indicates safety instructions

where non-compliance will involve some risk to safe
operation and personal safety and would damage the
equipment or property.

This symbol indicates "strong magnetic

field" safety instructions where non-compliance would
affect personal safety, pacemakers, instruments or
stored data sensitive to magnetic fields.

This symbol indicates explosive atmosphere zone

marking according to ATEX. It is used in safety
instructions where non-compliance in the hazardous
area would cause the risk of an explosion.

This symbol is used in safety instructions to

remind not to rub non-metallic surfaces with a dry
cloth; ensure the cloth is damp. It is used in safety
instructions where non-compliance in the hazardous
area would cause the risk of an explosion.

This sign is not a safety symbol but indicates

an important instruction in the assembly process.

1.6.2

Personnel qualification and training

All personnel involved in the operation, installation,
inspection and maintenance of the unit must be
qualified to carry out the work involved. If the personnel
in question do not already possess the necessary
knowledge and skill, appropriate training and instruction
must be provided. If required the operator may
commission the manufacturer/supplier to provide
applicable training.

Always coordinate repair activity with operations and
health and safety personnel, and follow all plant
safety requirements and applicable safety and health
laws and regulations.

1.6.3

Safety action

This is a summary of conditions and actions to help
prevent injury to personnel and damage to the
environment and to equipment. For products used
in potentially explosive atmospheres section 1.6.4
also applies.

MAGNETIC FIELD PRESENT: This

equipment may affect electronic equipment or other
devices that are influenced by magnetic fields.
Because magnetic drive pumps contain powerful
magnets, anyone with a heart pacemaker MUST
NOT disassemble these pumps. Also, keep all credit
cards, bank cards, watches, computer disks and
anything else which can be damaged by magnetic
fields away from these pumps when disassembled.

NEVER DO MAINTENANCE WORK

WHEN THE UNIT IS CONNECTED TO POWER (Lock
out.)

GUARDS MUST NOT BE REMOVED WHILE

THE PUMP IS OPERATIONAL

DRAIN THE PUMP AND ISOLATE PIPEWORK

BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.

FLUORO-ELASTOMERS (When fitted.)

When a pump has experienced temperatures over
250 ºC (482 ºF), partial decomposition of fluoro-
elastomers (example: Viton) will occur. In this
condition these are extremely dangerous and skin
contact must be avoided.

HANDLING COMPONENTS

Many precision parts have sharp corners and the
wearing of appropriate safety gloves and equipment
is required when handling these components. To lift
heavy pieces above 25 kg (55 lb) use a crane
appropriate for the mass and in accordance with
current local regulations.

THERMAL SHOCK

Rapid changes in the temperature of the liquid within
the pump can cause thermal shock, which can result
in damage or breakage of components and should be
avoided.

NEVER APPLY HEAT TO REMOVE IMPELLER

Trapped lubricant or vapour could cause an explosion.
