3 SAFETY PRECAUTION
DANGER
WARNING
CAUTION
Never face the outlet of a
valve when it is discharging
as this may result in serious
personal injury or death
Never dismantle a valve in
line without making
absolutely sure there is no
remaining or residual
pressure
Protect yourself by wearing
the necessary protective
equipment to prevent
possible injury
• Never stand in front of the discharge side of a safety valve if the valve is operating or being tested.
• Always wear personal protective equipment (PPE): PPE should consist of but not be limited to ear protection, eye
protection, and the use of protective clothing (gloves, headgear, etc). Noise can be extremely high and can occur
suddenly. Steam and hot water can burn. Superheated steam is NOT visible.
• Always lower the operating pressure before making any adjustment to the valve. Always gag the valve before making
any ring setting adjustments.
• Before removing a valve for disassembly, ensure that there is no remaining pressure upstream the valve and that
the valve is isolated from the system pressure.
• Before performing each pop test on the safety valve, ensure that no personnel are close to the valve. The steam
which could escape during the operation could cause serious personal injury.
• When a lift test is performed using the lifting lever, be sure to use a rope or a chain whilst standing at a safe
distance away from the valve and any potential steam escapes.
• Valves under the operating pressure may relieve at any time. Never strike the body or tamper with the valve as such
practice could cause premature relief.
• Never modify or change the valves, especially when they are under pressure. It is essential that you inform Trillium
Flow Technologies™ in ALL instances if any machining of parts is to be considered. Deviation from critical
dimensions can adversely affect the performance of a safety valve.
A safety valve is a self-acting product. Always consider the potential dangers associated with the product and never minimise them.
Each plant or installation has its own safety rules. Be aware of them and follow them carefully.
