Introduction

The chemical manufacturing company based in Gujarat had spent crores of rupees on setting up their manufacturing unit. The machines had been installed, workers were recruited, and it was all set to roll out the first batch for transportation. But just a few days before the planned start date, it was realized that they cannot store some hazardous materials without getting proper permission from the Petroleum and Explosive Safety Organisation (PESO).

This is something that happens much more often than most business owners realize. No matter if it is a chemical manufacturing plant, solvent storage unit, paint factory, pesticide plant, or an industrial gas plant; all these businesses need approvals before being allowed to commence operations.

PESO Approval for Chemical Industries is no formality - it is one of the most essential safety measures that have been put in place to safeguard the life of workers, community members, and the surroundings from any hazard arising due to hazardous materials. It ensures that the manufacturing unit is adhering to the prescribed safety measures.

If you manufacture, store, import, transport or handle any hazardous chemicals, then the information about PESO approval procedure will definitely come in handy.

What is PESO Approval for Chemical Industries?

“PESO Approval for Chemical Industries” is the official clearance granted by the Petroleum and Explosives Safety Organisation (PESO) on behalf of the Government of India. The clearance is an indication that the chemical industry has fulfilled the necessary safety norms regarding the storage, handling, transport, production, and usage of chemicals, petroleum products, compressed gases, and explosives.

The main aim of PESO is to reduce accidents through safety norms. Chemical industries dealing with hazardous substances such as flammable liquids, toxic chemicals, industrial gases, and solvents must fulfill the norms before starting business operations.

The approval process involves a detailed technical assessment of several factors, including:

• Plant layout and site plan
• Storage tanks and vessels
• Pressure equipment
• Fire protection systems
• Safety distances
• Ventilation arrangements
• Emergency response measures
• Operational safety procedures

Only after these aspects comply with PESO guidelines is approval granted.
