Major Nitrous Oxide Factory Bust: 1,652 Tanks Seized

On September 14, the Metropolitan Police Bureau and the Thai Food and Drug Administration launched a raid on an illegal nitrous oxide factory and warehouse in the Prawet district after detecting a large-scale operation. The factory was receiving bulk shipments of nitrous oxide, converting it from liquid to gas form, and repackaging it into small cylinders for distribution to customers at major tourist destinations across Thailand.

During the search, officers found 10 Myanmar workers and two Chinese managers on the premises. They seized 1,652 ready-to-sell nitrous oxide tanks, five 48.6-kilogram blue cylinders, 4,200 empty containers, two trailers carrying 36,000 kilograms each of N2O, filling equipment, compressors, pressure regulators, and two pickup trucks.

According to Deputy Police Chief Pallop Airmthala and Special Branch Commander Chotiwan Luangvilai, the factory had been operating illegally for over a year. The operation imported nitrous oxide by the truckload, converted it to gas, and filled smaller containers for wholesale distribution at around 1,000 baht per kilogram. The gas was sold primarily to foreign tourists who use it for recreational purposes.

The two trailers alone contained 72,000 kilograms with a wholesale value of approximately 72 million baht, making it one of the largest illegal nitrous oxide facilities ever discovered in Thailand. Officials are investigating the legality of all gas imports and plan to expand their investigation to distributors and buyers nationwide.

The Thai FDA's director of the Product Safety Complaint and Enforcement Center, Aranya Theppituk, warned the public about the dangers of inhaling nitrous oxide from balloons or cartridges, noting that excessive inhalation can replace oxygen in the lungs and central nervous system, potentially causing serious harm or death.
