Key Hazards
- Gauge failure from overpressure
- Sudden release of pressure during installation or removal
- Exposure to hot, chemical, or pressurized fluids
- Incorrect gauge range or rating
- Damaged threads, lenses, or fittings
- Misreading pressure due to poor gauge condition or placement
2–3 Minute Talk Script
Pressure gauges help workers understand system conditions, but they can create hazards when they are damaged, installed incorrectly, or exposed to pressure beyond their rating.
Workers should know what system the gauge is connected to and what material is inside. Water, steam, chemicals, air, gas, oil, and wastewater all create different exposure hazards.
The gauge should be rated for the expected pressure and compatible with the system. A gauge with the wrong range, material, or connection can fail or give misleading information.
Gauges should be inspected before use. Cracked lenses, bent needles, damaged threads, leaks, corrosion, unreadable faces, or broken fittings should be corrected before relying on the gauge.
Pressure should be isolated and relieved before removing or replacing a gauge whenever possible. A gauge fitting can release fluid, gas, or stored pressure unexpectedly.
Workers should stand out of the line of fire when opening valves, pressurizing a gauge, or loosening fittings. Sudden release can cause impact, injection, burn, or splash hazards.
Hot fluids, steam, and chemicals may require PPE such as gloves, face protection, goggles, aprons, or respiratory protection depending on the system.
Safe pressure gauge use depends on knowing the system, using the correct gauge, controlling stored pressure, and treating fittings and readings with caution.
Safety Reminders
- Use gauges rated for the system pressure and material.
- Inspect gauges, fittings, threads, and lenses before use.
- Do not rely on damaged or unreadable gauges.
- Isolate and relieve pressure before removal when possible.
- Stand clear of the line of fire when pressurizing.
- Use PPE for hot, chemical, or pressurized fluids.
- Report leaking or failed gauges immediately.
Ask the Crew
- Is the gauge rated for the expected pressure?
- Is the gauge compatible with the system material?
- Are the gauge and fittings in good condition?
- Has pressure been isolated or relieved before removal?
- What exposure could occur if the gauge or fitting fails?
