Brief Account of Incident
Basically one of their gasoline tanks overflowed. A security guard detected a strong smell and notified shift control who sent two operators to investigate. They don’t walk but they drive. Say no more, the bang was so big and shook the apartment building in Pattaya about 20kms away.

The fire spread from one tank to 4 others before it was contained and eventually put out by allowing the fuel to completely burn out, over 100,000 litres. There was 8 fatalities and 13 hospitalized with serious injuries. Fortunately it had occurred during silence hours and save over 100 people as admin building, maintenance workshop store and medical center were either completely gutted or severely damaged by the blast.

Lesson Learned
1. If you see a release of flammable material: Turn in the plant alarm, identify the wind direction.
2. If you hear any plant alarm: Stop work, extinguish cigarettes, if you’re in a vehicle immediately stop and turn off the engine.
3. If the plant alarm for toxic gas: Assembly point is in control room.
4. There should a rules for taking vehicles anywhere inside a plant. For such situation confine all vehicles to the main roads and designated parking areas.
5. Never forget that we handle very dangerous chemicals. Be careful and follow the HSE procedures, operating procedures and maintenance procedures so horrible accidents such as this can be avoided.

On December 2, 1999, a fire started at the Thai Oil refinery near Bangkok. The fire spread from one tank to 4 others before it was contained and eventually put out. The fire caused seven fatalities, 13 other serious injuries requiring hospitalization, destroyed 150,000 barrels of gasoline, caused $22.3 million in damages, and shut down the plant for an extended period. Thousands of people were forced to flee their homes.

On December 27, a worker, Charnarong Theplak, was arrested and charged with negligence in the incident. According to police, Charnarong, who was working at the oil tank control room at the refinery on the night of the blast, had left a valve on one tank wide open when it was being filled. Oil that overflowed from the tank was ignited by a car engine started by staff members who tried to leave the area when they noticed the overflow.
