Industrial gases keep Indian industries running—oxygen for cutting and hospitals, LPG for heating, nitrogen for processes, acetylene for welding. But when gas storage goes wrong, consequences escalate fast. Leaks, fires, explosions, and regulatory shutdowns rarely come with second chances.
That is why PESO compliance audits for industrial gas storage and cylinder banks are not optional formalities. They are a statutory requirement and a critical safety control under Indian law.
This article explains PESO Compliance Audit requirements in India, applicable rules, audit scope, common non-compliances, and penalties—clearly, factually, and aligned with official regulations, without assumptions or filler.
What Is PESO and Why It Matters?
The Petroleum and Explosives Safety Organization (PESO) is India’s statutory authority under the Ministry of Commerce & Industry responsible for regulating:
-
Petroleum products
-
Compressed gases
-
Gas cylinders and pressure vessels
-
Explosives and hazardous substances
PESO ensures that storage, handling, filling, and use of gases do not endanger life, property, or the environment.
If your facility stores industrial gas cylinders in bulk, PESO jurisdiction applies—without exception.
What Is a PESO Compliance Audit?
A PESO compliance audit is a systematic assessment of gas storage facilities and cylinder banks to verify compliance with:
-
Gas Cylinder Rules
-
Approved PESO drawings and licenses
-
Safety distances and layout norms
-
Handling, storage, and operational controls
The audit checks whether the installation matches what PESO approved—not what was planned years ago.
Why PESO Compliance Audits Are Critical in India
Industrial gas incidents often occur due to:
-
Improper storage distances
-
Overcrowded cylinder banks
-
Missing safety signage
-
Unauthorized modifications
-
Poor cylinder handling practices
PESO audits are critical because:
-
PESO licenses are mandatory for bulk storage
-
Fire NOC and insurance depend on compliance
-
Violations attract heavy penalties and shutdowns
-
Liability after incidents is severe and personal
In gas safety, “almost compliant” means non-compliant.
Key Regulations Governing Industrial Gas Storage in India
PESO compliance audits are based on specific, enforceable rules, not generic safety guidelines.
Gas Cylinder Rules, 2016
The Gas Cylinder Rules, 2016 form the backbone of compliance for:
-
Storage of compressed and liquefied gases
-
Cylinder banks and manifolds
-
Handling, transport, and usage
They specify:
-
Safety distances
-
Maximum storage quantities
-
Cylinder segregation
-
Licensing requirements
Petroleum Rules & Allied Notifications (Where Applicable)
For LPG and similar gases, additional petroleum safety provisions apply, enforced by PESO.
State Fire Service Rules & NBC
The National Building Code of India (NBC) complements PESO rules by defining:
-
Fire protection requirements
-
Emergency access
-
Building safety provisions
PESO and Fire Departments work in parallel—not in isolation.
Gas Storage Installations Covered Under PESO Audits
-
Industrial gas cylinder banks
-
Oxygen, nitrogen, hydrogen storage
-
LPG cylinder storage (industrial use)
-
Acetylene cylinder installations
-
Gas manifolds and header systems
-
Bulk gas storage yards
If multiple cylinders connect to a common system, PESO scrutiny applies.
Step-by-Step PESO Compliance Audit Process
Step 1: License & Documentation Review
Auditors verify:
-
Valid PESO license or approval
-
Approved layout drawings
-
Storage quantity limits
-
Renewal status
Expired licenses equal non-compliance.
Step 2: Location & Safety Distance Verification
Key checks include:
-
Separation from buildings and boundaries
-
Distance from ignition sources
-
Clear access for emergency response
Safety distances are non-negotiable.
Step 3: Cylinder Storage & Segregation
Auditors examine:
-
Upright storage with proper restraints
-
Separation of full and empty cylinders
-
Segregation of incompatible gases
-
Protection from heat and direct sunlight
Mixed or unsecured storage is a frequent violation.
Step 4: Manifold & Piping System Inspection
Audit focus areas:
-
Approved manifold design
-
Pressure regulators and relief devices
-
Leak-free joints and fittings
-
Correct material compatibility
Temporary or improvised piping fails audits instantly.
Step 5: Fire & Explosion Protection Measures
Auditors verify:
-
Fire extinguishers of correct type
-
No smoking and hazard signage
-
Earthing and bonding (where applicable)
-
Emergency shut-off provisions
Gas storage without fire protection is indefensible.
Step 6: Handling & Operational Practices
Audit checks include:
-
Trained and authorized handlers
-
Safe cylinder movement methods
-
Use of trolleys and caps
-
No rolling or dragging of cylinders
Most gas accidents involve handling errors.
Step 7: Emergency Preparedness
Auditors review:
-
Emergency response plans
-
Leak control procedures
-
Availability of PPE
-
Coordination with fire services
Preparedness matters more than paperwork during leaks.
Common Non-Compliances Found in PESO Audits
Most PESO violations repeat across industries:
-
Storage exceeding approved quantity
-
Cylinders stored too close to buildings
-
Missing PESO license display
-
Damaged or corroded cylinders
-
Unauthorized layout modifications
-
No trained personnel
These issues develop gradually—and fail suddenly.
Audit Frequency & PESO License Renewal
-
PESO licenses require periodic renewal
-
Compliance audits are recommended annually
-
Re-audit is required after layout or quantity changes
Any modification without PESO approval invalidates compliance.
Penalties for PESO Non-Compliance in India
PESO violations can result in:
-
License suspension or cancellation
-
Immediate shutdown of gas storage
-
Monetary penalties
-
Prosecution under applicable acts
-
Criminal liability after incidents
After an accident, PESO compliance history becomes legal evidence.
PESO Compliance Audit vs Fire Safety Audit
A fire safety audit checks fire systems and evacuation.
A PESO audit checks gas-specific regulatory compliance.
Fire audits ask: “Can we control a fire?”
PESO audits ask: “Will this gas installation cause one?”
Both are essential—but not interchangeable.
Best Practices to Maintain PESO Compliance
-
Never modify gas layouts without PESO approval
-
Display license and safety signage clearly
-
Train handlers regularly
-
Inspect cylinders before use
-
Conduct periodic third-party audits
Gas safety depends on discipline, not memory.
