Alerts & Learnings Working at Height - Person in Line of Fire Two workers were working approximately 5 metres above the ground on a permanent access platform, removing the lid on a Tri-Ethylene Glycol (TEG) Discharge Coalescer as part of a scope of works to replace the filter cartridges. While slackening the studs, using a hytorq cassette and a flogging spanner as a backing spanner, the flogging spanner was dropped and fell through the gap between the access platform and the Coalescer. The falling spanner struck the upper isolation valve, causing damage to the flange, and then impacted a nearby line to the open drain system before landing on the ground. The spanner fell within the established exclusion zone. To view this Safer Together safety alert in full, click the 'Download Alert' button above.
