Repair works at a paper production plant in Samut Prakan, Thailand sparked a massive 20-hour long blaze on Wednesday. The inferno has so far left US $3 million in damages.

Flames spread through the warehouse on Wednesday November 21, shortly after 5pm when workers were finishing their shifts. Over 800 people work at the plant. Around 50 workers were still at the facility when the blaze broke out.

Authorities reported that a welding machine fell from the roof during repair works, landing on paper being stored below.

Fire crew arrived at the scene shortly after but it was almost 24 hours later when they finally extinguished the blaze.

Staff were able to remove some paper rolls. The fire has left some THB100 million (3m USD) in damages, though nobody was injured.

Flames spread through the warehouse in Samut Prakan, Thailand, on Wednesday (21/11) afternoon shortly after more than 800 workers had finished their shift at around 5pm.

Investigators said the inferno was caused by workmen repairing a roof of the building when sparks from a welder fell onto the paper being stored below.

The men climbed down from the building while around 50 more who were working overtime fled outside into the car park. Fumes from the fire were so bad that nearby residents complained of feeling sick from the smoke and had to wear face masks.

Fire crews arrived and began dousing the blaze which spread rapidly after huge bundles of paper caught alight. They are seen in the video also spraying water on untouched rolls of paper to try to prevent it spreading.

The inferno was finally fully extinguished on Thursday afternoon almost 24 hours after it first stated. There were no injuries but police have estimated of damages are some THB100 million (3m USD).
