A stored-energy awareness course that trains your eye to see pressure before it releases — hose whip, blowout, and injection risk — then has you bleed down and verify zero energy across 19 interactions. Pressure becomes a hazard you recognize instead of a system you trust.
Pressure hazard awareness for everyone who works on or near pressure-retaining equipment — boilers, pressure vessels, air receivers, compressed-air and compressed-gas systems, and pressure piping and fittings: plant, maintenance, production and mechanical-room workers, operators and the people working nearby alike.
Equip everyone who works on or near pressure-retaining equipment to understand that you can't see pressure and it doesn't leak politely — a pressure system holds invisible stored energy that lets go all at once, not a slow warning leak but a sudden and total…

Who this course is for
Workers who work around compressed air, hydraulics, pressurized cylinders, or stored-energy systems in shops, plants, and maintenance settings.
Plant, production and process workers who operate or work alongside boilers, pressure vessels, air receivers and pressure piping
Maintenance, mechanical and millwright workers who isolate, depressurize and break into pressure systems and piping
Mechanical-room, HVAC and utilities staff who work near boilers, compressors, air receivers and steam or compressed-air lines
New and returning workers being oriented to a plant with pressure-retaining equipment, and anyone who works nearby a pressure system
What you will learn
Explain that you can't see pressure and it doesn't leak politely — a pressure system holds invisible stored energy that lets go all at once, not a slow warning leak but a sudden and total release
Name the four pressure-hazard words found on every system — stored energy, over-pressure, the relief / safety device, and sudden release — and identify pressure systems (boiler, vessel, air receiver, compressed-air/gas, pressure piping)
Describe the failure modes — vessel or receiver rupture, BLEVE, steam flash and steam burn, a whipping hose or line, stored energy from a trapped line, and ejected fittings — and why "it's only air" is wrong
Explain the over-pressure control hierarchy — design and registration, over-pressure protection (relief / safety valve), operate and monitor within limits, isolate and depressurize before line-breaking, then procedure and PPE last
Live by the family rule — never defeat a relief device (never cap, gag, weight or screw one down) — and report a weeping, blocked or wrong-set relief device, because the relief valve is the last line between contained energy and catastrophe

Common questions
How long does Pressure Hazard Awareness take?
About 1 hour online, over 5 modules, at your own pace. It ends with a final test that needs 80% to pass.
How long is the Pressure Hazard Awareness certificate valid?
One year from the day you pass. Orientra’s standard is for pressure-safety training to be reviewed at least annually and whenever the equipment, systems or processes change — a new boiler or vessel, a modified relief device, a different task, or a near-miss all trigger a refresh.
Which laws and standards does Pressure Hazard Awareness cover?
Manitoba Workplace Safety and Health Act (C.C.S.M. c. W210); Manitoba Steam and Pressure Plants Act (C.C.S.M. c. S210); Manitoba WSH Regulation MR 217/2006; and 5 more listed on this page.
Who should take Pressure Hazard Awareness?
Workers who work around compressed air, hydraulics, pressurized cylinders, or stored-energy systems in shops, plants, and maintenance settings.
