General Safety Instructions, cont.
All possible hazards may not be identified in this manual. Conduct your
own safety risk assessment given your specific system, environment, and
configuration, and ensure proper control procedures are in place to prevent
personal injury or illness and property, product or environmental harm.
When the valve is under pressure, do not place any part of your
body near or in the path of the outlet of the main valve or other
discharge areas. Doing so will result in serious injury or death
upon valve discharge.
If a test gag is provided with the valve, it must be removed prior to
installation. Failure to do so will result in equipment failure, serious
injury or death in the instance of an overpressure event.
Never attempt to remove, adjust, maintain, or repair a pressure relief
valve while it is installed in a pressurized system unless you have been
properly trained to do so. Doing so may result in serious injury or death.
Ensure proper isolation of any energy sources and residual pressures
by complying with all local, state and country-specific regulations/
directives applying to energy control procedures (lockout/tagout).
Ensure that the pressure relief valve and system is at an ambient
temperature before inspecting, servicing, or repairing. The valve,
system, and contents may be extremely hot or cold. Failure do so
may result in serious injury.
The discharge from the main valve outlet or any other vents, should be
piped or vented to a safe location to eliminate the potential for serious
injury or damage during relief operation.
Prior to valve disassembly, ensure that proper controls are implemented
to address potential exposures to hazardous substances, including
gases, liquids, or process byproducts contained in or contaminating
the valve. Consult applicable material safety data sheets (MSDSs) and
established exposure limits for the substances expected to be present
to ensure proper exposure controls are implemented. Failure to do so
could result in serious injury or illness.
To ensure the valve is free to operate, check the inlet and outlet piping
for potential obstructions which may exist as a result of process fluid
solidification, polymerization or other system problems. Failure to do so
could render the valve inoperable, leading to serious injuries or damage
in the event of system over-pressurization.
Use extreme caution when inspecting a pressure relief valve for
leakage. Always stay clear of the valve outlet during seat leakage
testing as the valve can suddenly open fully causing serious injury.
Doing so could result in serious burn, chemical or injection injury.
Use all appropriate personal protective equipment to protect against
process hazards, including but not limited to, pressurization, temperature
extremes, noise, and chemical hazards. Failure to do so could result in
serious injury or death.
Always use the appropriate tools, and in the correct manner, for
adjustment or servicing of valves. Failure to do so could result in injury.
It is the responsibility of the customer and user of Farris valves to
properly train their personnel on all required maintenance procedures
and safety standards to prevent injuries.
Farris can provide comprehensive training on the maintenance and repair
of all Farris products. Contact your local Farris representative or the factory.
Improper handling, storage, installation and maintenance of a PRV can
cause damage to the valve and will invalidate the warranty. Please
follow all recommended procedures.
