9.1 Decommissioning safety

WARNING: MAINTENANCE SAFETY
Risk of injury or damage to equipment. Obey the safety instructions and make note
of all precautions.
WARNING: LOCKOUT AND TAGOUT
Risk of injury or death. Electricity, nitrogen and water supplies are possible hazardous
energy sources. Lockout and tagout sources before you do the maintenance to the
pump.
WARNING: HOT SURFACES
Risk of burns. Do not touch the pump exhaust or check valve while the pump is in
operation since the temperatures of these parts can be high. Let the pump cool for 1
hour before disconnecting.
WARNING: USE PROTECTIVE EQUIPMENT
Risk of injury or death. Personal protective equipment should be checked and used as
specified by its supplier. Hazardous chemicals that have been pumped are located in
the pumps and piping. Use of correct protective gloves and clothing along with a
respirator is recommended if contact with substances is possible. Particular caution
should be exercised when you work with fluorinated materials which can possibly
have been exposed to temperatures greater than 260 °C. Refer to Edwards Safety
Data Sheets for more information.
▪ Make sure that the maintenance technician knows the safety procedures related to
the products pumped.
▪ Allow the pumps to cool to a safe temperature before installing the lifting eye bolts
or starting maintenance work.
▪ Vent and purge the system with nitrogen before decommissioning the system.
▪ Isolate the system and other components in the process system from the electrical
supply so that they cannot be operated accidentally. Note that the emergency stop
switch on the system is not an electrical isolator, unless a disconnect box accessory
is installed.
▪ Wait for minimum 4 minutes after switching off the electrical supply before
touching any electrical component on the system.
▪ Make sure that oil or water collected in the secondary containment drip tray is
removed before you move the system.
▪ Protect sealing faces from damage.
▪ Replacement intervals will vary depending on your application.
▪ Do not touch or inhale the thermal breakdown products of fluorinated materials
which can be present if the system has been overheated to 260 °C and above.
