A recent fire incident at the Expo 2020 Dubai construction site was caused by an unexpected technical problem during some welding work, a forensic investigation has revealed.
Following 12 scientific experiments and re-enactments, forensic investigators were able to determine that fire tire was caused by technical problems during welding work, which refuted the testimonies of a worker and an engineer who said there was no welding work in progress.
They also concluded that the welding operations led temperatures of the tube to rise above 350 degrees Celsius, which caused it to ignite.
The equipment was then stored away by the worker without taking necessary safety precautions. After workers were evacuated, he informed an engineer of the incident.
The engineer advised him to remain quiet. Investigators also discovered messages circulated among workers telling them to deny their presence at the site on the day of the fire.
When confronted, both the worker and the engineer admitted to lying.
