Calculation support, not a guaranteed safety decision.

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.

Lifting and logistics · 3 tasks

Telehandler unloading

Kinetic calculator
Motion Gravity Mechanical

Telehandler unloading adds reach, boom height and tip-over exposure to normal forklift hazards.

Crane lift

Gravity calculator
Gravity Motion Mechanical

A crane lift places a suspended load above people, plant and structures along the lift path.

Switchgear movement on skates

Kinetic calculator
Motion Gravity Mechanical

Moving heavy switchgear on skates creates crush, tip-over and line-of-fire exposure.

Work at height · 3 tasks

Gravity Mechanical Sound

Installing cable tray, basket and ladder overhead involves sustained work at height with tools, fixings and containment sections above other trades, plus cutting and drilling noise.

Gravity Mechanical Sound

Installing unistrut framing and bracketry involves overhead drilling into concrete, anchor loads and power tool use above other trades.

Rack structure installation

Gravity calculator
Gravity Mechanical Sound

Installing rack frames and support steel inside data halls involves heavy sections, overhead fixing and drilling, grinding and screwing in enclosed space.

Electrical and power · 3 tasks

Cable drum handling

Kinetic calculator
Motion Gravity Mechanical

Moving and setting up heavy cable drums creates rolling, crush and uncontrolled-movement exposure.

Cable pulling

Trigger checks
Mechanical Motion Electrical

Cable pulling puts hands near rollers and pinch points while tension is applied to heavy cable runs.

Electrical Mechanical

Terminating and testing cables works at the boundary between dead construction wiring and systems that can be energised from elsewhere.

Mechanical and pressure · 4 tasks

Pump set installation

Gravity calculator
Gravity Mechanical

Installing pump sets involves heavy units, mechanical alignment work and later rotating and pressure energy.

Fan start-up

Trigger checks
Mechanical Motion Electrical

Starting fans introduces rotating energy and airflow into systems that people may still be working on.

Pump start-up

Trigger checks
Mechanical Electrical Pressure

Starting pumps introduces rotating and pressure energy into pipework that may still be open or occupied by other trades.

HVAC ductwork installation

Gravity calculator
Gravity Mechanical Sound

Installing ductwork involves large sections handled overhead, sharp sheet edges and cutting, drilling and grinding above other trades.

Fire and protection systems · 1 task

Gravity Mechanical Sound

Installing dampers in duct penetrations combines overhead work, spring-loaded mechanisms and drilling and cutting at the slab or wall line.

Civil, structures and fit-out · 4 tasks

Motion Gravity Mechanical Sound

External earthworks use excavators, loaders and rollers around people on foot, with ground instability and buried services.

Excavation

Trigger checks
Gravity Motion Mechanical Sound

Excavation work combines ground collapse exposure, plant movement and buried services.

Trenching

Trigger checks
Gravity Mechanical Sound

Trenching creates long open excavations with collapse exposure and repeated entry by operatives.

Structural steel erection

Gravity calculator
Gravity Mechanical Sound

Erecting structural steel combines crane lifts, work at height, heavy sections being landed and bolted, and grinding and welding.

Commissioning and testing · 1 task

Electrical Mechanical Pressure Thermal

Integrated testing runs multiple building systems together, so equipment can start, move or change state without local warning.
