Although the government has made the NS certification mark mandatory to all LPG industries, these 48 companies have not heeded to the government's regulation for safety.

The Bureau of Standards and Metrology in last December had initiated action against LPG industries operating without acquiring the NS certification. They had stated that they would acquire the certification mark within two months but have not done so yet.

Bureau Director-General Bishwa Babu Pudasaini said the number of LPG industries taking the NS certification mark from the Bureau has however increased.

"Three LPG industries have taken the certification after campaign has begun to take action against those that have not, while 20 are in the process of taking it," he informed.

According to him, the Bureau has asked for mandatory documentation with all LPG industries for providing the NS certificate to them.

The LPG industries that have taken NS certification so far include Manoj Gas Industry-Birgunj, Shree Krishna Gas Industry-Dhading, Saibaba Gas Industry-Dhading, Nepal Gas Industry-Balaju, Janaki Gas Industry-Nawalparasi, Metro Gas Industry-Dhading, and NL Gas Industry-Birgunj.
