Cable tray installation at height: energy sources and direct controls

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.

High-energy check

Tray sections and powered tools dropped from height can exceed the 1500 J trigger. Overlapping trades below are the main exposure.

Trigger checks

Mechanical
Moving parts, tools, tension, rotation or stored mechanical force.
Sound
Harmful noise or impulse sound.

Direct controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

Tray sections are secured immediately, never rested loose overhead.
Tools are tethered and fixings are in closed pouches.
Area below is excluded or protected while work is overhead.
Platform or MEWP controls are in place for the working height.
Coordination with trades below is agreed before starting.
Stop if exclusion below cannot be maintained.

For your SPA or pre-start

State the work height, how tray sections and tools are secured, and how the area below is excluded or protected while work is overhead.
