On Sept 16, 2011, many people in Thailand were traumatised by the series of bombings that shook Su-ngai Kolok in Narathiwat, but few knew about the people who put their lives on the line that night.
Mr Sakchai at work.
"There weren’t that many people injured in the first blast," he recalled. "My team tried to get the people out of the area, fearing that there would be another bomb nearby. Just moments later there was another explosion."
The second bomb was detonated in front of the Parkson Hotel. Mr Sakchai and his team immediately rushed to scene.
Suddenly, another bomb was set off. The flames from the blast severely burned Mr Sakchai's arms, legs and face. Shrapnel flew at him, cutting into his skin.
One of Mr Sakchai's colleagues, Seksan Rojpanasiri, died in the explosion.
Earlier in the hospital
At least three people were killed and more than 50 wounded in the attacks that night.
It took Mr Sakchai around two months to recover in the burn unit of Yala Hospital.
People tend to hide in the face of frightening situations but this was not the case for Mr Sakchai. After he recovered, he faced his fears head-on by returning to his duty.
"I’ve been asked several times whether I was afraid, whether I was going to quit. I answered, if I quit and someone got hurt, who will help them? It may sound like a cliche but when you get to help someone, the feeling is indescribable," he said.
Statistics show that in 2012, around 4,700 medical staff in Narathiwat, Yala, and Pattani went out on around 21,600 emergency medical missions.
There are a total of 150,911 volunteers nationwide under the Emergency Medical Institute of Thailand.
