Incident Overview

SEOUL, June 1 (Reuters) - Five people have died and two others were injured on Monday after an explosion and fire on a South Korean production line for rocket propellant at a factory operated by Hanwha Aerospace in the city of Daejeon, officials said.

Survivors and Victims

The two survivors, including one who was badly burned, had escaped from the facility themselves, a fire official told a briefing.

"Authorities have yet to identify the victims because their bodies were severely damaged," a health official told the same briefing.

Explosion Cause and Investigation

A fire official said that an explosion had triggered the blaze, though the cause of the blast was still being investigated.

Impact on Hanwha Aerospace

Shares in Hanwha Aerospace fell 2.8% in afternoon trade, while the holding company Hanwha Corp saw its shares drop 3.4%.

Factory Operations and Safety

The blast appeared to have occurred while water was being used to clean explosive material from tools making rocket propellant, a Hanwha official told a company briefing.

"We bow our heads in apology to the victims and their bereaved families," said Chief Executive Officer Son Jae-il, pledging to cooperate fully with authorities to determine the cause of the accident.

Victim Identities and Employment

The five dead included two temporary workers in their 20s and all were employed by Hanwha, the company said.

Company Background

Hanwha is a defence and aerospace company. Its factory in Daejeon produces large propulsion engines and handles rocket propellants.

Authorities' Response

Authorities were unable to obtain the factory's layout since it is protected under national security laws, an official said at an earlier briefing.

South Korean President Lee Jae Myung called for the mobilisation of all available resources to respond to the accident and for an investigation, his office said in a text message to reporters.
