VESDA and fire alarm installation: energy sources and direct controls

Installing detection pipework, detectors and panels involves overhead drilling and work that continues into rooms with live systems as commissioning progresses.

High-energy check

Tools and fittings dropped from height can exceed injury thresholds. Panels become energised during commissioning while installation work continues nearby.

Trigger checks

Pressure
Compressed gas, liquid, hydraulic, pneumatic or vacuum energy.
Sound
Harmful noise or impulse sound.

Direct controls to verify

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

Tools and fittings at height are tethered or contained.
Panel energisation status is confirmed before work inside a panel.
Detection isolations are authorised and recorded before dusty work.
The area below overhead drilling is excluded or protected.
Isolations are reinstated and confirmed at the end of the shift.

For your SPA or pre-start

State the work height and access, how tools are secured, which panels are energised and how detection isolations are authorised and recorded.
