<Anchor> The



circumstances of the accident at the time are being revealed one after another in relation to the death of three workers in an explosion at the Yeosu industrial complex three days ago. The prime contractor claimed that it had never instructed its subcontractors to work on welding, but on the day of the accident, the work permit written by the prime contractor was marked as 'hot work'.



Reporter Park Seung-hyun of KBC reports exclusively.



<Reporter> The



explosion occurred at the Yeosu Industrial Complex, killing three workers at a subcontractor as an explosion occurred with a 'pop' sound.



The day after the accident, Il Industrial said through an on-site briefing that it had never been instructed to do welding.



[Kim Soo-nam/Lee Il Industrial Environment Safety Team Leader (the day before): I do not know why and why it happened there, although it is supposed to not do welding in the procedure. It is presumed that no hot work was done there.] This



is the 'Safety Work Permit' of Iil Industries that was obtained by KBC on the day of the accident.



There is a checkmark in 'Warm work'.



It is said that a fireproof cloth to prevent the inflow of inflammable substances and prevent flame scattering has been prepared.



Contrary to the claim of the company, the police believe that they directly ordered the welding work.



[Jeon Kook-hyeon / Plant Union Labor Safety Director: (The company) said it was a simple bolting operation, but he gave permission to work with fire. If you look at the marked parts... .]



However, no safety measures were taken.



Although the storage tank was filled with flammable chemicals about 30%, it was not emptied at all, and it turned out that there was no safety manager in charge of the overall operation.



Trusting only what the company said that all potential hazards were removed, the welding team, which consisted of a team of three, was driven to their limbs without any measures.



[Gimjongju / plant trade union chief bujibujang:'ll buds except removing gas chemicals and people went up work, and then ignored it all to have a safety inspector



irresponsible work of Yeosu Industrial Complex to handle toxic chemicals directives and Insecurity has once again brought in talent.
