I wish to know the Safety standards to be implemented on these constructions sites ?

Is there any specific training courses which are a MUST for construciton companies ?

most of the companies, jsut keep a board "Safety First" and 2-3 Nepaliees with a helmet & coverall. The so-called safety officers, who have not gone thru any safety training courses,

earlier it is heard that 50 laboures shold have one Safety officer with Medical First Aid certified

Can someone update ??
