OBJECTIVE
Prevent uncontrolled release of stored energy during hydrostatic or pneumatic pressure testing.
WHY IT MATTERS
Pressure testing can expose systems to energy levels very different from normal operating conditions. A small connection failure can release significant energy.
Pneumatic testing can contain considerably more stored energy than hydrostatic testing because gases are compressible and therefore requires additional precautions.
Before testing, confirm test pressure, equipment limits, blinds, calibrated gauges, relief devices and the exclusion zone.
REALISTIC SITE SCENARIO
A crew pressure-tested a piping system using a temporary blind that was not adequately rated.
As pressure increased, the connection began to deform and a significant leak developed around the flange.
The event could have been prevented through correct rated equipment, an approved test package, controlled pressurisation and an effective exclusion zone.
REMEMBER
Never tighten a pressurised connection or search for a leak with your hand.
KEY HAZARDS
Equipment or piping failure from overpressure.
Ejection of blinds, flanges or fittings.
Hose whip from pressurised connections.
High-pressure fluid injection injuries.
High stored energy during pneumatic testing.
Incorrect or uncalibrated pressure gauges.
Unsuitable temporary test equipment.
Personnel entering the exclusion zone.
CONTROLS
Use an approved test procedure.
Verify the test boundaries.
Use calibrated pressure gauges.
Inspect connections, hoses and blinds before testing.
Establish an exclusion zone.
Increase pressure gradually and under control.
Remain clear of potential projectile paths.
Never adjust connections while pressurised.
Stop the test following abnormal pressure loss.
Fully depressurise before intervention.
SUPERVISOR MESSAGE
Team, today's pressure test involves stored energy. We will not start until test pressure, blinds, gauges and the exclusion zone are verified. No one will approach or intervene on a connection while it remains pressurised.
TEAM QUESTIONS
What is today's test pressure?
What is the system's allowable pressure limit?
Are pressure gauges within calibration?
Where is the exclusion zone?
How will pressure be safely released?
Who will stop the test if leakage occurs?
FIELD VERIFICATION
Test procedure available
Boundaries verified
Gauge calibrated
Connections inspected
Blinds suitable
Exclusion zone established
Personnel clear
Communication agreed
