Recently, a fire broke out following the explosion of a building housing the reactor unit at a chemical factory in Sangareddy, Telangana, killing over 35 people.

Industrial Accidents and Hazards

• Industrial accidents are unexpected events in the workplace that cause harm, injury, or even death to personnel, or result in property damage. Industrial hazards are the conditions or situations that can lead to these accidents.
  • These can include machinery-related accidents, falls, fires, explosions, chemical exposures, and transportation incidents within the workplace.
• The National Disaster Management Authority (NDMA) has reported that there were more than 130 chemical accidents that caused the death of 259 people in the last 10 years. 

Key Types of Industrial Hazards

• Chemical Hazards: Hazards caused by exposure to toxic, flammable, or corrosive chemicals through inhalation, ingestion, or skin contact. They can lead to poisoning, burns, cancer, and long-term organ damage.
  • Example: Bhopal Gas Tragedy (1984) – MIC gas leak killed ~15,000 people and injured over 5 lakh.
• Fire and Explosion Hazards: These arise from ignition of combustible materials or sudden release of pressure, leading to uncontrolled fire or blast events that endanger life and infrastructure.
  • Example: Sigachi Industries Explosion (Telangana, 2025) – 36 deaths due to lack of blast prevention and outdated machinery.
• Radiological Hazards: Hazards due to exposure to ionizing radiation (alpha, beta, gamma rays), which can damage tissues, mutate genes, and contaminate the environment.
  • Example: Chernobyl Disaster (1986) – Nuclear reactor meltdown led to radioactive fallout affecting millions.
• Mechanical Hazards: Hazards from machinery, tools, or equipment that can cause injuries such as crushes, cuts, or amputations due to moving parts, failure, or improper use.
  • Example: NTPC Plant Boiler Blast (2017) – Over 40 deaths due to failure in pressure control and safety valves.
• Biological Hazards: Hazards caused by exposure to infectious agents like bacteria, viruses, or toxins, especially in pharmaceutical, biomedical, and food industries.
  • Example: Pathogen leaks in vaccine labs or improper biomedical waste handling leading to infection risk.
• Psychological (Psychosocial) Hazards: Hazards arising from stress, long working hours, isolation, harassment, or traumatic exposure, affecting workers’ mental and emotional well-being.
  • Example: Migrant workers in hazardous units working 12–14 hours daily without job security or mental health support, as seen in Hyderabad’s chemical hubs.

Causes of Industrial Accidents

• Technical Failures: Breakdown of equipment or faulty design due to outdated technology and lack of upgrades.
  • Many industrial units operate with machinery that should have been replaced years ago.
• Human Error: Mistakes made by workers due to fatigue, stress, inexperience, or poor judgment.
  • Human error, often triggered by long shifts and lack of support, is a common contributor to accidents.
• Poor Maintenance: Skipping or delaying scheduled maintenance to reduce operational costs. Preventive maintenance is often compromised, especially in older units.
• Inadequate Safety Training: Lack of proper knowledge of hazard handling, emergency response, and safe practices among workers and managers.
  • According to a report, 80% of Indian factory workers lack formal safety training.
• Weak Regulatory Oversight: Failure of government or inspection bodies to enforce safety rules or conduct proper audits.
  • Inspection protocols are often inadequate or not implemented at all.
• Absence of Emergency Preparedness: Missing fire alarms, gas detectors, evacuation plans, or emergency medical response systems.
  • Sigachi Industries lacked basic emergency infrastructure like fire sensors. 
• Unsafe Work Culture: Neglect of worker safety in management priorities; absence of accountability or safety-first mindset.
  • Operators and managers lack risk awareness; hazard analysis is often absent.

Consequences of Industrial Accidents

• Human Loss and Health Impact: Industrial accidents often lead to large-scale fatalities, severe injuries, burns, amputations, and chronic illnesses due to chemical exposure. Survivors may live with permanent disabilities.
  • In 2021, the Labor Ministry informed Parliament that at least 6,500 employees had died while working at factories, ports, mines and construction sites in the preceding five years.
• Livelihood and Economic Insecurity for Workers: Victims—mostly poor migrant labourers—lose their source of income. In the informal sector, workers lack insurance, compensation, or re-employment support, pushing families into deeper poverty.
  • Ex-gratia payments often come late or are insufficient.
• Environmental Degradation: Accidents involving chemicals or gases pollute air, water, and soil, causing long-term ecological harm. These effects are often irreversible and threaten surrounding communities.
  • Vizag gas leak (2020) polluted air and damaged biodiversity in the region.
• Industrial and Financial Losses: Industries face massive financial loss due to damage to infrastructure, halted operations, compensation costs, and regulatory penalties. 
  • It also disrupts supply chains and local economies.
• Regulatory and Policy Shifts: After major accidents, governments are compelled to revise laws, improve inspections, and implement stricter penalties. However, reforms are often reactive, not preventive.
  • After Bhopal, the Environment Protection Act (1986) and Factory Amendment Rules (1987) were introduced.
• Psychological and Social Trauma: Survivors, workers, and families suffer from post-traumatic stress disorder (PTSD), depression, and fear. 
  • Children lose parents, and entire communities experience mental health breakdowns.
• Decline in Industrial Confidence and Productivity: Frequent accidents erode investor confidence and disrupt long-term planning. Fear among workers reduces morale and productivity.
  • Telangana’s reputation as a safe pharma manufacturing hub is under threat.

Challenges in Curbing Industrial Accidents in India 

• Ineffective Regulation and Inspection Mechanisms: State factory inspectorates are understaffed, irregular in audits, and often compromised by local political–industrial nexus.
  • Risk-based inspection (as proposed in OSH Code 2020) is not uniformly implemented.
  • Many hazardous units escape scrutiny due to informal operations or legal ambiguities.
• Overlapping and Poorly Enforced Legal Frameworks: Laws like Factories Act, Environment Protection Act, Public Liability Insurance Act, and new OSH Code coexist with conflicting jurisdictions.
  • Penalties for violations are too low to act as deterrents.
• Emergency Unpreparedness and Infrastructure Deficit: Many factories lack essential safety infrastructure: alarms, emergency exits, PPE, response teams.
  • External emergency support (e.g., fire brigade, ambulance) is often too far from industrial zones.
• Delayed Justice and Inadequate Compensation: Legal processes for holding industry management accountable (as in Bhopal) are slow and uncertain.
  • The Public Liability Insurance Act (1991) and Environment Relief Fund are underutilized or evaded.
  • Victims struggle to access immediate financial or health compensation despite ex gratia announcements.

Way Forward: Mitigating Industrial Accidents in India

• Strengthen Enforcement of Safety Laws: Ensure uniform implementation of the Occupational Safety, Health and Working Conditions Code, 2020 across all states.
  • Empower State Inspectorates with adequate manpower, digital surveillance tools, and independent audit authority.
  • Introduce graded penalties and blacklisting for repeat offenders.
• Modernisation of Industrial Infrastructure: Mandate retrofitting of old plants with sensors, fire suppression systems, gas detectors, and auto-shutdown mechanisms.
  • Encourage the use of Industry 4.0 solutions—IoT, AI-based hazard prediction, and real-time monitoring, especially in high-risk sectors like chemicals and oil.
• Institutionalise Risk-Based Inspections: Move from random inspections to data-driven, risk-prioritised audits, focusing on high-hazard industries.
  • Use GIS and accident history to classify units into red/yellow/green categories for inspection frequency.
• Upskilling and Safety Training: Make safety training mandatory under apprenticeship and contractual onboarding schemes.
  • Design vernacular training modules for migrant laborers on hazard response, equipment handling, and legal rights.
• Community-Centric Disaster Preparedness: Conduct mock drills for both on-site and off-site emergency scenarios.
  • Develop a community alert system integrated with district disaster management authorities.
• Universalise Accident Insurance and Relief Mechanisms: Ensure compulsory enrollment of all hazardous industry workers under ESIC and Public Liability Insurance.
  • Operationalise the Environmental Relief Fund with real-time claim disbursal mechanisms.
• Institutional Accountability and Transparency: Make third-party safety audits and compliance reports publicly accessible.
  • Create a National Industrial Accident Database (NIAD) for tracking causes, responses, and remedial actions.

Conclusion

Industrial accidents represent a critical intersection of ethics, governance, technology, and labor rights. India’s path forward lies in preventive safety culture, regulatory overhaul, and inclusive worker protections—ensuring that “ease of doing business” does not come at the cost of human dignity and lives.
