HVAC ductwork installation: energy sources and direct controls

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

High-energy check

Duct sections dropped from height can exceed the 1500 J trigger. Sheet edges cut deeply, and overhead tool work adds dropped-object and noise 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.

Duct sections are supported until every hanger is fixed.
Cut edges are deburred or handled with cut-resistant gloves.
The area below overhead work is excluded or protected.
Cutting and grinding are done at a set station where possible.
Hearing protection is worn during cutting and grinding.
Stop if a hanger point pulls or the structure flexes.

For your SPA or pre-start

State the section mass and fixing height, how sections are supported until fixed, the exclusion below and how cut edges are handled.
