The Wooshin Golden Suites Fire was a fire that occurred at an officetel in Marine City, Haeundae, Busan, South Korea on October 1, 2010. The fire started on the fourth floor, caused by a spark from an electrical outlet, and rapidly spread to the top of the building via external combustible cladding; five injuries were reported.^[1][2]

Fire

• The fire started around 11:34am on the 4th floor.^[3][4]
• A fire engine with a 52-metre ladder was launched, but firefighters could not control the fire because it spread so quickly.
• Within 20 minutes, the blaze had reached the 38th floor.^[2]
• According to the Korea Times, the blaze was extinguished after 2.5 hours, after mobilising dozens of fire engines and a helicopter that dropped water on the building from above.^[4] According to Nathan White and Michael Delichatsios, writing in Fire Hazards of Exterior Wall Assemblies Containing Combustible Components, the original 4th-floor fire was put out by 1 pm, with the entire building fire-free by 6.48 pm.^[2]
• Some residents were evacuated by helicopter from the building's roof.^[2]

Causes and background

• There was no sprinkler in the 4th-floor room where the fire started.^[2]
• The reinforced glass in the windows hindered firefighters.
• The building featured flammable aluminium composite cladding with a polyethylene core, along with glass wool or polystyrene insulation; the fire rapidly spread up the facade, reaching the top of the tower within 20 minutes.^[5][2]
• The fire primarily spread up a vertical U-shaped indentation in the building's exterior, which created a chimney effect, possibly enhanced by wind blowing in from the sea.^[2]

Casualties

• 4 residents and 1 fire fighter were injured.
