Industries that manufacture, store, or handle hazardous chemicals, petroleum products, compressed gases, and other dangerous substances face significant process safety risks. A failure in equipment, process controls, or operating procedures can lead to fires, explosions, toxic releases, and other major incidents.
To reduce these risks, industries in India must follow applicable safety regulations and implement appropriate engineering and operational controls.
However, understanding process safety compliance can be challenging because different regulations may apply depending on the type of industry, hazardous substances, quantities, storage conditions, and processes involved.
Process safety compliance means ensuring that industrial processes, equipment, hazardous materials, and safety systems meet applicable legal and regulatory requirements.
The main objective is to reduce the risk of serious industrial incidents, including:
Effective process safety compliance combines regulatory requirements with hazard identification, risk assessment, engineering safeguards, safe operating procedures, maintenance, training, and emergency preparedness.
Industries handling hazardous materials can face serious consequences if process hazards are not properly identified and controlled.
A strong process safety management approach can help organizations:
Compliance should therefore be viewed as an ongoing safety process rather than a one-time activity.
India does not have a single standalone Process Safety Management (PSM) regulation applicable to all industries. Process safety compliance is governed through multiple Acts, Rules, standards, license conditions, and sector-specific requirements.
Some important regulatory frameworks include:
The Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989 (MSIHC Rules), 1989 are particularly relevant to facilities involved in the manufacture, storage, or import of specified hazardous chemicals.
Depending on applicability, requirements can include areas such as:
Industries handling significant quantities of hazardous chemicals should determine whether their facility falls within the applicable thresholds and requirements.
Chemical accidents can affect not only workers but also neighbouring facilities and surrounding communities.
The Chemical Accidents Rules focus on emergency planning, preparedness, and response for chemical accidents.
Industries handling hazardous chemicals should have appropriate emergency arrangements based on credible accident scenarios and the hazards present at their facilities.
Industries involved in the storage, handling, or other regulated activities involving petroleum products may need to comply with the Petroleum Rules, 2002.
Requirements can involve areas such as:
The specific requirements depend on the type and quantity of petroleum products and the facility's activities.
Facilities involved in the manufacture, possession, storage, transportation, or use of regulated explosives may be subject to the Explosives Rules, 2008.
These requirements can cover areas such as:
Organizations dealing with explosives should identify the specific requirements applicable to their operations.
The Gas Cylinders Rules, 2016 are relevant to regulated activities involving gas cylinders and compressed gases.
Depending on the activity, organizations may need to address requirements related to:
Facilities handling compressed gases should assess their specific gases, quantities, cylinder types, and storage arrangements to determine applicable requirements.
The SMPV(U) Rules, 2016 are relevant to certain static and mobile pressure vessels used for storing or handling compressed and liquefied gases.
These requirements can be important for facilities involving substances such as LPG, LNG, and other regulated gases.
Depending on the installation, compliance may involve requirements related to:
Facilities involved in activities regulated under the Ammonium Nitrate Rules, 2012 may have specific requirements relating to storage, handling, transportation, licensing, and safety.
The applicability depends on the nature and quantity of ammonium nitrate handled by the facility.
Other important Indian regulatory frameworks
One of the most important questions for any facility is:
The answer depends on several factors, including:
For this reason, companies should not assume that the same regulations apply to every industrial facility.
A regulatory applicability assessment can help identify the requirements relevant to a specific site.
Regulatory compliance is not limited to obtaining licences or maintaining documents.
A practical process safety program may include:
• Hazard Identification
Identify potential hazards associated with processes, chemicals, equipment, and operating conditions.
• Risk Assessment
Evaluate the likelihood and consequences of hazardous scenarios and determine whether additional risk-reduction measures are required.
• Engineering Safeguards
Implement appropriate safeguards such as:
• Equipment Integrity
Safety-critical equipment should be inspected, tested, maintained, and managed to ensure that it remains capable of performing its intended safety function.
• Emergency Preparedness
Facilities handling hazardous materials should have appropriate emergency response procedures based on credible scenarios such as fire, explosion, toxic release, or chemical spill.
• Employee Training
Employees should understand the hazards associated with their work, operating procedures, emergency actions, and relevant safety controls.
Regulatory compliance and process safety studies often work together.
♦ HAZOP Study
A Hazard and Operability Study (HAZOP) systematically identifies potential deviations from the intended design or operating conditions.
It can help identify:
♦ Quantitative Risk Assessment
QRA evaluates the risks associated with major accident scenarios using quantitative methods.
It can help organizations understand potential consequences from scenarios such as:
QRA can support risk-informed decisions related to facility design, emergency planning, risk reduction, and safety management.
♦ Hazardous Area Classification
For facilities handling flammable gases, vapours, or combustible dusts, hazardous area classification can help identify locations where an explosive atmosphere may occur and support the appropriate selection of electrical and instrumentation equipment.
♦ Common Process Safety Compliance Gaps
Some common gaps found during industrial safety assessments include:
Regular assessments can help organizations identify these gaps and implement corrective actions before they contribute to a major incident.
Organizations can strengthen process safety by following a structured approach:
1. Identify applicable regulations
Determine which laws, rules, licences, and regulatory requirements apply to the facility.
2. Identify process hazards
Conduct appropriate hazard identification and risk assessment studies.
3. Review existing safeguards
Check whether engineering and administrative controls are adequate for identified risks.
4. Maintain safety-critical equipment
Establish appropriate inspection, testing, and maintenance programs.
5. Strengthen emergency preparedness
Develop and periodically test emergency response plans.
6. Train employees
Ensure employees understand process hazards, operating procedures, and emergency actions.
7. Conduct periodic audits
Regular process safety and compliance audits can help identify gaps and track corrective actions.
Regulatory compliance should not be treated as a one-time exercise.
Changes in processes, equipment, chemicals, production capacity, or facility layout can introduce new hazards and may affect regulatory applicability.
Organizations should therefore periodically review their:
This helps ensure that process safety controls remain effective as the facility evolves.
Effective compliance requires both regulatory understanding and technical risk assessment.

These services can help organizations identify process hazards, evaluate risks, review existing safeguards, and develop practical recommendations for improving process safety.
Process safety regulations play an important role in protecting people, assets, and the environment from major industrial incidents.
Regulations such as the MSIHC Rules, Chemical Accidents Rules, Petroleum Rules, Explosives Rules, Gas Cylinders Rules, SMPV(U) Rules, and Ammonium Nitrate Rules may apply to different industrial activities depending on the substances, quantities, processes, and equipment involved.
However, compliance is more than simply following regulations or maintaining documentation. Organizations need to identify hazards, assess risks, maintain safety-critical systems, prepare for emergencies, train employees, and periodically review their process safety performance.
A structured and risk-based approach can help industries meet applicable requirements while creating safer and more reliable operations.
Note: Regulatory applicability varies depending on the facility, substances handled, quantities, processes, equipment, and other site-specific factors. Organizations should verify the latest applicable legal requirements with the relevant regulatory authorities before making compliance decisions.
