An explosion at South Korean petrochemical company Yeochun NCC's (YNCC) plant killed four people and injured four, a Yeosu Fire Station official announced on Friday.
"Currently, the third plant has not stopped production and the first and second plants are operating.. as of now there is no impact to production," a YNCC official told a briefing.
"The labour ministry is on the scene to decide whether to suspend production or shut down a plant, and I think it will be decided according to administrative measures."
The official noted that the blast took place during a leak test in a cleaning process that is a procedural operation carried out every four years.
In 2020, at least 38 people were killed and 10 others injured in a fire that broke out in a warehouse under construction in South Korea.
The South Korean Yonhap news agency quoted the firefighting teams saying that the fire broke out in a four-story under-construction warehouse in Icheon city, 80 kilometers southeast of Seoul, and spread “very quickly”, which prevented the evacuation of a number of workers who were still inside.
