For the 1st concern, it is a valid individual SSHE concern, however, it is involved building facilities and some other people surround. I would recommend to raise this to a proper channel such as SOC,.. K.Mesaya should be able to help find the right process.
For the 2nd concern, yes, PTTEP wants to save energy and it was clear for this campaign when launched that it is set to be automatic off so if anyone wants to have light for wok, he or she can turns the light on for their specific zone from the switch close to the toilet. Again, please ask K.Mesaya where the switch is.
