Introduction

A manufacturing industry in Durgapur, who plans to install gas at the new plant, may have selected the required equipment already. A chemical industry in Haldia may be planning to install a storage tank, while a company in Kolkata may be looking forward to installing compressed gas cylinders.

One important question that should come up before the installations of these activities is, whether the said activities fall under PESO approvals, and what would be the right route for the regulatory approval.

The Petroleum and Explosives Safety Organisation (PESO) is a Government of India body, which is responsible for implementing certain regulatory standards regarding petroleum, explosives, compressed gases, gas cylinders, and pressure vessels. PESO is an entity that operates under the Department for Promotion of Industry and Internal Trade.

In case of industries in West Bengal, compliance needs to be looked into along with the engineering and project planning process. A PESO Consultant in West Bengal would be helpful in linking up the real-life activity with the relevant PESO regulation before the final installation process.

What Is a PESO Consultant in West Bengal?

A PESO Consultant in West Bengal helps businesses understand and comply with the requirements of PESO (Petroleum and Explosives Safety Organisation) for regulated petroleum products, compressed gases, gas cylinders, pressure vessels, explosives and related activities.

The process starts by understanding the actual project rather than selecting a licence form immediately. The consultant reviews the material being handled, storage quantity, equipment, site conditions, technical drawings, pipelines, tanks and the nature of the operation.

This assessment helps determine the appropriate PESO approval or licence and identify documentation or technical requirements before the application is submitted. It can also help businesses avoid problems caused by mismatched drawings, incorrect equipment details or changes made during installation.

Diligence Certifications provides support for PESO applicability assessment, documentation, technical coordination, application filing, regulatory queries, inspection preparation, renewals and amendments, helping businesses manage their PESO compliance requirements more systematically.

Why Is PESO Compliance Important for Businesses in West Bengal?

There are a wide range of industries in West Bengal, including manufacturing, chemical, engineering, petroleum-related industries, warehouses, pharmacy, industrial gases and other companies which may involve regulated materials or equipment.

It becomes challenging to make a project when the issues of compliance are considered only after installing the equipment.

Consider the case when a company decides to install two pressure vessels and in the process of installation another one is added due to some changes in production requirements. From the practical point of view, this would appear to be a simple expansion. However, from the regulatory point of view, this addition of another pressure vessel requires another assessment of installation and its approval.

In the same way, the problem may appear if the storage tank is moved, enlarged, piped systems or gases are changed The solution is obvious - one should consider PESO requirements in the early stage of the project.

Who May Need PESO Approval in West Bengal?

There is no single PESO licence that applies to every industrial business Applicability depends on the material, quantity, equipment, storage arrangement and actual activity.

Businesses that may need to assess PESO requirements include:

• Petroleum storage facilities
• LPG installations
• Compressed-gas facilities
• Industrial gas suppliers
• Gas-cylinder filling units
• Gas-cylinder manufacturers
• Gas-cylinder testing facilities
• Pressure-vessel installations
• CNG and LNG-related facilities
• Chemical manufacturing units
• Pharmaceutical facilities
• Petroleum handling businesses
• Certain pipeline projects
• Explosives-related businesses
• Fireworks-related operations
• Ammonium nitrate-related activities
• Importers of specified regulated equipment
• Manufacturers of specified pressure equipment

The important point is that the industry name alone does not determine PESO applicability.

Two businesses operating in the same sector may have different regulatory requirements because their materials, quantities, equipment and processes are different.

Which PESO Rules Apply in West Bengal?

The applicable regulatory framework depends on the nature of the activity.

Petroleum Rules, 2002

The Petroleum Rules, 2002 regulate specific activities involving petroleum, such as the regulated storage, transportation and handling of the substance.

The requirement varies depending on factors such as the type of petroleum in question, the amount, storage setup and location among others. PESO makes the Petroleum Rules public through its official website.

Gas Cylinders Rules, 2016

The Gas Cylinders Rules, 2016 regulate specific activities involving gas cylinders such as manufacturing, filling, storing and other related processes.

For example, PESO’s official forms database refers to Form-C as an application for the grant, amendment or renewal of a licence to fill and/or store compressed gas in cylinders.

The regulation is very pertinent to companies running their operations at industrial gas and cylinder stations.

SMPV(U) Rules, 2016

The Static and Mobile Pressure Vessels (Unfired) Rules, 2016 popularly known as the SMPV(U) Rules regulate specific activities involving pressure vessels with compressed gases and related materials.

PESO provides the current version of the SMPV(U) Rules through its official website.

Explosives Rules, 2008

Specific activities in relation to manufacture, possession, storage, transport, and handling of explosives may be covered by the Explosives Rules, 2008.

This depends on the nature of the explosive, the quantity, the activity and the premises involved.

Ammonium Nitrate Rules, 2012

Specific activities involving ammonium nitrate may be covered by the Ammonium Nitrate Rules, 2012.

A company planning to store or handle such explosive substances needs to verify applicability before setting up its premises.

According to the published jurisdiction order of PESO, West Bengal is classified along with Andaman & Nicobar Islands, Bihar, Jharkhand, Orissa and Sikkim under the East Circle. The sub-circles under the East Circle have been identified as Bhubaneshwar, Patna and Ranchi.

The present contact address of the East Circle of PESO is located in Nizam Palace, A.J.C. Bose Road, Kolkata.

Documents Required for PESO Approval in West Bengal

There is no universal document list for every PESO application.

Depending on the approval category, documents may include:

• Company incorporation documents
• PAN and GST details
• Authorised signatory information
• Land ownership or lease documents
• Site plan
• Plant layout
• Process description
• Storage capacity details
• Tank specifications
• Pressure-vessel details
• Cylinder specifications
• Pipeline drawings
• Equipment datasheets
• Manufacturer certificates
• Test certificates
• Inspection records
• Safety arrangements
• Existing PESO licence
• Declarations and undertakings

What really matters here is not just having the documents The data has to be consistent throughout the application, drawings, specifications for equipment, and actual installation.

For example, if the capacity of the tank in the drawing does not match the data in the specification sheet, there could be an explanation required from the applicant. This could lead to unnecessary regulatory inquiries A good PESO documentation package is not just complete.

---

Why Are Technical Drawings Important for PESO Compliance?

Technical drawings help PESO understand the physical arrangement of a regulated installation.

Depending on the project, drawings may show:

• Storage tanks
• Pressure vessels
• Gas cylinders
• Pipelines
• Valves
• Filling points
• Buildings
• Boundary limits
• Access routes
• Fire-fighting arrangements
• Safety equipment
• Relevant installation details

Consider a plant where a pressure vessel was shown in one location during the design stage but moved during construction because of a civil-work change.

The change may appear minor to the project team. However, the business should assess whether the revised arrangement affects the regulatory documentation.

PESO Approval Process in West Bengal

Step 1: Understand the Activity

Start with the material, quantity, equipment, storage arrangement and actual business operation.

Step 2: Check PESO Applicability

The activity is assessed against the relevant regulatory framework, which may include Petroleum Rules, Gas Cylinders Rules, SMPV(U) Rules or Explosives Rules.

Step 3: Review the Proposed Site

The location, storage area, equipment arrangement, access and relevant safety provisions are reviewed.

Step 4: Prepare Technical Documents

Drawings, equipment specifications, certificates and other supporting documents are compiled according to the applicable process.

Step 5: Submit the Application

The relevant application is filed through the applicable PESO online system.

PESO’s official forms database contains application forms covering different activities under the Gas Cylinders Rules, Petroleum Rules and other regulatory frameworks.

Step 6: Regulatory Scrutiny

The application and supporting information are examined under the applicable regulatory process.

Step 7: Respond to Queries

If observations are raised, the applicant may need to provide clarification, revised drawings or additional documentation.

Step 8: Inspection, Where Applicable

Where an inspection is required, the actual installation should correspond with the submitted documents.

Step 9: Approval or Licence

Once the applicable requirements are satisfied, the relevant approval or licence may be issued.

Step 10: Maintain Compliance

Future changes to equipment, capacity, layout or operations should be assessed to determine whether renewal, amendment or additional approval is required.

What Does a PESO Consultant Actually Handle?

A consultant’s role is broader than completing an online form.

Regulatory Applicability

The consultant reviews the proposed activity and helps identify the relevant PESO requirements.

Technical Document Review

Equipment specifications, layouts and supporting documents are reviewed for consistency.

Application Preparation

The application and supporting information are organised according to the applicable process.

Online Filing

The consultant can assist with coordinating the online submission.

Regulatory Queries

If PESO raises an observation, the consultant can help coordinate the response and supporting documents.

Inspection Preparation

Where inspection is applicable, the business can review the site and documentation before the inspection.

Renewal and Amendment

Existing approvals should be reviewed when there are changes in equipment, capacity, ownership, layout or operating conditions.

Diligence Certifications describes its PESO consultancy as covering documentation, application coordination, clarification of objections, inspection preparation, renewal and amendment support.

Common PESO Compliance Mistakes in West Bengal

Choosing the Licence Before Understanding the Activity

The first question should be what the business is doing, not which licence form appears easiest.

Preparation of Drawings at the Final Stage

The PESO requirements become less problematic to consider when the technical arrangement is evaluated as part of the project planning process.

Supplying Inconsistent Information

The equipment capacity, number, placement, and specifications must stay consistent throughout the whole application.

Relying on a Previously Approved Application for Additional Capacity

Additional capacity or adding a vessel, tank, cylinder storage facility or other installations must be taken into consideration.

Overlooking Changes in the Site Plan

Changes in the placement of the equipment, piping, or storage facilities must be considered regarding their potential impact on the regulations.

Using Outdated PESO Requirements

PESO keeps issuing amendments, drafts, procedures and regulatory information. For example, PESO’s Official Search contains 2025 amendments to the Explosives Rules and 2026 draft amendments to the SMPV(U) Rules.

This being said, a checklist developed for the previous project cannot be reused for a current application.

Timeline, Cost and Validity of PESO Approval

There is no universal timeline, cost or validity period for every PESO application.

Factor	What affects it
Timeline	Application category, documentation, scrutiny, queries and inspection
Cost	Government charges, testing, technical work and consultancy
Validity	Depends on the specific licence or approval
Renewal	Depends on the applicable statutory requirement

A new pressure-vessel installation is different from a gas-cylinder licence renewal. Likewise, petroleum storage approval may involve different technical considerations from an amendment to an existing licence.

The appropriate estimate should therefore be based on the actual project scope rather than a generic PESO fee or timeline.

---

Benefits of Professional PESO Consultancy

Compliance area	Practical benefit
Applicability assessment	Helps identify the appropriate regulatory route
Technical review	Helps identify documentation inconsistencies
Drawing review	Helps align installation plans with the application
Documentation	Helps organise the submission
Filing support	Helps coordinate online filing
Query handling	Helps address regulatory observations
Inspection preparation	Helps compare site conditions with submitted documents
Renewal and amendment	Helps manage future changes

For a large industrial project, this coordination can be particularly useful because engineering, procurement, operations and compliance teams often work independently.

A consultant can help keep the regulatory requirements connected to the technical decisions being made on the project.

PESO Compliance for Industrial Businesses in West Bengal

The industrial profile of West Bengal makes it clear that there are various scenarios where PESO applicability might occur.

A chemical plant will require regulated gases. An engineering company might have pressure equipment. A petroleum-based company might require storing regulated petroleum products. The gas company might need to deal with cylinders. The manufacturing unit might have to set up a new storage system due to increased production.

They cannot follow the same process for PESO approval.

The proper criterion will depend upon the following factors:

What will be the substance + quantity of the substance + the equipment used + the manner of storage + the nature of work.

That is why the applicability check may prove helpful before procurement and installation.

---

Current PESO Regulatory Position

The official PESO portal should remain the primary reference for current regulatory information.

Businesses should verify the latest:

• Applicable rule
• Approval category
• Application form
• Technical requirements
• Online procedure
• Government charges
• Jurisdiction
• Amendments
• Inspection requirements
• Post-approval conditions

The Petroleum Rules, 2002, Gas Cylinders Rules, 2016 and SMPV(U) Rules, 2016 are published by PESO on its official website.

These regulatory frameworks, such as the Petroleum Rules, Gas Cylinder Rules, SMPV(U) Rules, Explosives Rules and Ammonium Nitrate Rules have been covered in its 2024-25 annual report as well.
