PCS Hero Star reflects the importance of training, emergency response, and frontline decision-making in security operations.
For Thanisorn Singkaew, Security Supervisor at PCS, one routine working day at an international school became a real example of why CPR training and workplace readiness matter.
During his shift, a radio call came through from Building B5. A cleaner had collapsed inside the women’s restroom on the ground floor.
Thanisorn responded immediately.
When he arrived, several colleagues were already assisting, but the cleaner remained unconscious. The restroom was poorly ventilated, and the situation required fast action.
He quickly assessed the condition.
The pulse was unclear. Breathing was faint.
There was no time to wait.
I didn’t think about being a hero,” he said. “I just thought about how to bring her back to her family.
With 24 years of experience in security operations, including seven years supporting hospital environments, along with regular CPR and first aid training, he made the decision to begin CPR immediately.
Within approximately two minutes, the cleaner regained consciousness.
He then moved her safely out of the restroom, coordinated the emergency response through 1669, and supported the school nurse by providing critical information until the situation was fully under control.
This outcome was made possible by preparation.
Throughout his career, Thanisorn has completed continuous training in CPR, first aid, AED use, and emergency response. These are practical skills that strengthen workplace safety and ensure faster response during critical moments.
You don’t have to be the best,” he said. “You just need to know what to do and do it correctly.
For PCS, this reflects the role of security beyond access control and site supervision.
Security professionals are often the first responders in live environments. Their ability to stay calm, assess risk, and act correctly protects people, supports business continuity, and reduces operational disruption.
Even after our shift ends, we are still security professionals, Thanisorn said. If we can help, we should help; but we must always assess the situation first.
As a supervisor, he believes leadership starts with discipline, consistent standards, and ensuring teams are ready before emergencies happen.
Because, when seconds matter, preparation is what protects lives.
