They are not hard to find.
For many years I worked offshore Songkhla, just around the corner from Trang.
I work for a drilling company as a supervisor, we have strict safety standards. We would employ Thai electricians, Thai's that worked on our rig would comply and obey all of these very strict rules and regulations.
I'm sure other industries onshore here in Thailand have competent electricians.
With proper training and supervision lives will be saved.
