Introduction

In order to meet the increasing demand for critical care, a multi-speciality hospital underwent an extension of the ICU along with installation of oxygen cylinders, manifolds, and gas pipelines. Though all the facilities were present, during a normal inspection of the facility, it came into light that the hospital needed to obtain an approval from the relevant authorities to operate the medical gas system legally.

This is a fairly typical problem faced by many health facilities. Even as the primary concern of the hospital is providing high-quality care to the patients, it must be remembered that the adherence to safety standards in terms of storage and handling of medical gases is just as crucial. The PESO Approval for Hospitals Using Medical Gas helps hospitals to safely store, transport, and distribute medical gases like oxygen and nitrous oxide in accordance with the Indian regulations.

What is PESO Approval for Hospitals Using Medical Gas?

PESO approval for hospitals using medical gas refers to the statutory approval provided by the Petroleum & Explosives Safety Organisation (PESO) to hospitals engaged in storage, installation, and operation of medical gas system containing compressed and liquefied gas.

Medical gases commonly covered include:

• Medical Oxygen
• Nitrous Oxide
• Carbon Dioxide
• Medical Air
• Nitrogen
• Liquid Medical Oxygen (LMO)
• Other compressed medical gases used for diagnosis and treatment

As the gases are stored under high pressure in cylinders, cryogenic tanks, or manifolds, there is always a possibility of hazards like fire, explosions, pressure, or leakage if appropriate care is not taken.

PESO determines whether the hospital’s facilities, equipment, safety systems, installations, and procedures comply with safety regulations for issuing approvals.

Who Needs PESO Approval for Hospitals Using Medical Gas?

PESO Authorization for the Use of Medical Gases in Hospitals is needed by hospitals that keep or distribute more than the permitted amount of medical gases according to regulations. This helps ensure that medical gas equipment used meets safety standards.

The following healthcare facilities commonly require PESO approval:

• Multi-Speciality Hospitals - Hospitals with central oxygen plants, liquid medical oxygen (LMO) tanks, or medical gas pipeline systems.
• Government and Private Hospitals - Facilities operating ICUs, operation theatres, emergency departments, and critical care units.
• Super Speciality Hospitals - Cardiac, oncology, neurological, trauma, and transplant hospitals with high-capacity medical gas systems.
• Medical Colleges and Teaching Hospitals - Institutions using medical gases for patient care, training, and research.
• Cancer Treatment Centres - Facilities that use medical gases for specialised treatments and radiotherapy.
• Trauma, Emergency, and Dialysis Centres - Healthcare centres that rely on a continuous supply of medical gases for patient treatment.

Types of PESO Approval for Hospitals Using Medical Gas

The exact approval requirements depend on the type of medical gas installation, storage capacity, equipment configuration, and hospital operations.

Approval for Liquid Medical Oxygen (LMO) Storage Tanks

Hospitals storing Liquid Medical Oxygen (LMO) in cryogenic tanks require approval for the storage installation, safety distances, pressure systems, and associated equipment.

These installations are commonly found in medium and large hospitals with high oxygen consumption.

Approval for Medical Oxygen Cylinder Manifold Systems

Hospitals using manifold systems that connect multiple oxygen cylinders require approval to ensure safe cylinder storage, pressure regulation, ventilation, and emergency shutdown arrangements.

Approval for Medical Gas Pipeline Systems (MGPS)

Medical Gas Pipeline Systems distribute oxygen and other gases throughout different hospital departments.

Petroleum & Explosives Safety Organisation examines the design, pressure control systems, safety valves, emergency isolation systems, and installation standards before approval.

Approval for Pressure Vessels and Cryogenic Equipment

Cryogenic vessels, vaporizers, pressure vessels, and associated equipment used for medical gas storage must comply with prescribed engineering and safety standards.

Approval for Gas Cylinder Storage Areas

Hospitals maintaining large cylinder storage facilities require approval covering:

• Storage layout
• Ventilation
• Fire protection
• Cylinder segregation
• Safety signage
• Access control

Step-by-Step Process for PESO Approval for Hospitals Using Medical Gas

Approval Process through Petroleum & Explosives Safety Organisation for Hospitals Using Medical Gas has many different steps that must be considered to gain approval. Proper planning and documentation may prevent delays during the approval process.

Step 1: Assessment of Medical Gas Infrastructure

The approval procedure starts with an in-depth assessment of the hospital’s medical gas system including storage areas, pipelines, cylinder manifolds, pressure vessels, and other equipment.

As a result, it becomes possible to determine the relevant regulations taking into account the capacity of storage areas and the operations.

Step 2: Preparation of Technical Documents

Engineers produce all technical documents including drawings, layouts, equipment specifications, calculations, and other documents according to relevant standards.

Proper documentation is very important in order not to raise any objections.

Step 3: Submission of Application

After filling out the application form, together with the other necessary documents and government fees, it is then submitted to the Petroleum & Explosives Safety Organisation concerned.

Step 4: Technical Evaluation

The officials of Petroleum & Explosives Safety Organisation will review the submitted documents to check for adherence to safety codes, engineering codes, and installation codes.

Any discrepancy found could lead to requesting clarifications or submitting revised documents.

Step 5: Site Inspection

Where applicable, authorised officers conduct a physical inspection of the hospital premises to verify:

• Storage installations
• Medical gas pipeline systems
• Safety equipment
• Pressure vessels
• Fire protection measures
• Emergency shutdown systems
• Safety signage
• Operational readiness

Step 6: Compliance Rectification

Should the observation be raised during the inspection process, the hospital will need to take corrective action before moving forward with the approval process.

Step 7: Grant of PESO Approval

Once all the documentation is verified satisfactorily and the inspection process is completed successfully, the Petroleum & Explosives Safety Organisation will issue the approval.
