Introduction

Some months back, a company intending to increase its production capacity for industrial gas cylinders contacted us at Diligence Certifications seeking advice on the regulatory procedure. The company had already invested money in buying land, machinery, and production infrastructure, but could not start production due to lack of PESO approval.

From our analysis, it was established that the manufacturing unit needed a PESO approval prior to commencing any commercial production. There was a need for evaluation of the plant layout, safety provisions, technical drawings, and manufacturing process.

This problem is typical of companies trying to venture into regulated industries. Most companies tend to focus on installation of machinery and manufacturing process, yet they overlook the issue of necessary safety approvals prior to production.

A PESO Manufacturing License is a statutory document indicating that the products manufactured fall under the category of petroleum products, explosives, compressed gases, and others. This is evidence that the company has complied with safety regulations.

At Diligence Certifications, we assist businesses comply with PESO regulations.
