Referred to Hazardous chemical regulation defined the Company must re-inform the details of Hazardous chemical (สอ.1) that we used , produced and kept to Labor office within 31 January of each year (Annually) 
The last year I already informed our Hazardous chemical such as Liquid oxygen , Acetylene to them.
So, I need to remind all for comply with the regulation as per the time and I will assign to NOTTO for doing it the task.
