Key Hazards
- Sudden pressure changes or water hammer
- Strains from stuck, buried, or hard-to-turn valves
- Valve keys or tools slipping during operation
- Traffic exposure while operating valves in streets or right-of-way
- Pinch, crush, or struck-by hazards from tools, lids, and moving parts
- Unintended service disruption or flow change from operating the wrong valve
2–3 Minute Talk Script
Valve operation may look routine, but opening or closing valves can change system pressure, flow, and equipment conditions quickly.
Workers should verify the correct valve before operating it. Maps, tags, work orders, markings, and communication with operations should be used when needed.
Valve boxes, lids, and access points should be inspected before use. Workers should watch for traffic, debris, insects, water, damaged lids, and trip hazards.
Valve keys and operating tools should be in good condition and sized properly. Poorly fitted tools can slip or cause strain.
Valves should usually be operated slowly and with control. Rapid opening or closing can cause pressure surges, water hammer, main breaks, or equipment problems.
Workers should use good body position and avoid excessive force. A stuck valve should not be forced to the point of tool failure or injury.
Traffic control may be needed when valves are located in streets, parking lots, driveways, or public areas.
Safe valve operation depends on identifying the correct valve, using proper tools, controlling traffic exposure, operating slowly, and communicating any abnormal pressure, noise, or resistance.
Safety Reminders
- Verify the correct valve before operating.
- Inspect valve boxes, lids, and access points.
- Use the correct valve key or tool.
- Operate valves slowly and with control.
- Do not force stuck valves unsafely.
- Use traffic control when working in roadways.
- Report unusual resistance, noise, leaks, or pressure changes.
Ask the Crew
- Is this the correct valve for the task?
- What pressure or flow changes could occur?
- Is traffic control needed?
- Is the valve key or tool in good condition?
- What should workers do if the valve is stuck or behaves abnormally?
