Police probe reveals welder's negligence caused fire at Dubai Expo site

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.
Forensic fire investigation experts and criminologists at the Dubai Police's General Department of Criminal Investigation (CID) conducted 12 scientific experiments and re-enacted the incident of fire to determine the cause of the spark and reveal the facts concealed by the worker and engineer of the company operating at the site to evade responsibility.
The finding refuted the version of the worker and engineer who said there was no welding work in progress at that time. The investigators also concluded that the welding operations led to a rise in the temperature of the tube to more than 350 degrees Celsius, which caused it to ignite.
Engineer told worker not to tell anyone
The worker stopped what he was doing when he faced a technical fault. He then restored the equipment in the dedicated room without observing the safety requirements. After five minutes, he noticed an evacuation of all workers in progress from the site due to a fire. He immediately left the site and informed the engineer about what had happened during the welding and his negligence of safety measures. The engineer told him to keep quiet and to not tell anyone else as there were no witnesses there was no need to involve the company.
The investigators also found messages circulated among workers telling them to deny their presence at the site on the day of the fire.
When confronted with the facts, the worker and engineer admitted to concealing the truth.
