Follow all plant safety regulations, but be sure to observe the following:
• Always lower the working pressure before making any valve adjustment.
When making ring adjustments, always gag the valve before making the
adjustment. This will avoid possible personal injury.
• Do not stand in front of the discharge side of a safety valve when testing or
operating.
• Hearing and eye protection should be used when testing or operating a valve.
• Wear protective clothing. Hot water can burn and superheated steam is not
visible.
• When removing the safety valve during disassembly, stand clear and/or wear
protective clothing to prevent exposure to splatter, or any corrosive process
medium, which may have been trapped inside the valve. Ensure the valve is
isolated from system pressure before the valve is removed.
• Exercise care when examining a safety valve for leakage.
• Prior to each actuation, assure that no personnel are near the valve. Steam
escaping from the valve during actuation can possibly cause personal injury.
• When popping a safety valve for the first time, or after refurbishment, always
be prepared to actuate the valve with the lever while standing in a safe
place away from the valve. This may be done by fixing a rope to the lever for
actuating the valve from a distance.
• Striking a valve which is under pressure can cause premature actuation.
Never tamper with the valve when system pressure is near the valve set
pressure.
• Before performing any machining on valve parts, consult Baker Hughes
or its authorized representative. Deviation from critical dimensions can
adversely affect valve performance.
Lower pressure and
stand clear of discharge
when working on valve
to avoid severe personal
injury or death.
Know all valve exhaust/
leakage points to
avoid possible severe
personal injury or death.
