Tasks
Each card is a reference, not a to-do list: it shows the energy present in that activity, then links to a calculator or trigger check. Open a card to see the direct controls to verify before work starts.

Pipe spool installation
Gravity calculatorInstalling pipe spools involves heavy sections, work at height and future pressure energy in the completed system.
Hydrostatic pressure test
Trigger checksA hydrostatic test pressurises pipework with water to prove integrity before service.
Pneumatic pressure test
Trigger checksA pneumatic test uses compressed gas, which stores far more energy than water at the same pressure.
Refrigerant charging
Trigger checksCharging refrigerant handles pressurised chemical under pressure with asphyxiation and cold-burn exposure.
Chemical dosing
Trigger checksDosing water treatment chemicals involves corrosive or reactive substances under pressure in occupied plant spaces.
Pump start-up
Trigger checksStarting pumps introduces rotating and pressure energy into pipework that may still be open or occupied by other trades.
Process piping installation
Gravity calculatorInstalling chilled water and condensate pipework involves heavy pipe at height, threading and grinding, and future pressure in the completed system.
Fire and protection systems · 5 tasks
Clean agent cylinder handling
Trigger checksHandling suppression cylinders involves very high pressure vessels that become projectiles if a valve is damaged.
Fire mains pressure test
Trigger checksFire main acceptance testing pressurises large-diameter pipework, normally with water under NFPA 24. Air is only used as a cold-weather interim test and does not replace the hydrostatic test.
Sprinkler system installation
Gravity calculatorInstalling sprinkler pipework involves heavy pipe overhead, threading and grooving machinery, and a system that is later filled and pressurised.
VESDA and fire alarm installation
Gravity calculatorInstalling detection pipework, detectors and panels involves overhead drilling and work that continues into rooms with live systems as commissioning progresses.
Leak detection installation
Trigger checksInstalling leak detection cable and panels routes work along live or soon-to-be-live water systems under raised floors and in service corridors.
Civil, structures and fit-out · 2 tasks
Buried services exposure
Trigger checksExposing buried services risks striking electrical, gas, water or communications assets whose state is unknown.
Concrete pour
Trigger checksConcrete pours involve pumping under pressure, moving plant, formwork loading and chemical burn exposure.
Commissioning and testing · 1 task
Integrated systems testing
Trigger checksIntegrated testing runs multiple building systems together, so equipment can start, move or change state without local warning.
