Why in news?

Recently, in April 2026, a devastating explosion at a firecracker manufacturing unit in Thrissur, Kerala, killed 14 people and injured over 40 others just days before the 2026 Thrissur Pooram festival.

Last year, a fireworks display at the Thrissur Pooram festival led to safety concerns after a disoriented elephant ran amok, injuring 42 people, while another elephant had attacked its handler a day earlier.

Experts note that loud and irregular firecracker noise can disturb animals, affecting their behaviour.

Data from the Kerala State Pollution Control Board showed noise levels reaching 122.4 decibels, close to the limit set by the Central Pollution Control Board, highlighting risks associated with high-decibel fireworks.

Fireworks and Healthcare Risks: Impact of Noise Pollution on Hospitals

• Noise Levels vs Safety Standards - Fireworks noise levels can far exceed safe limits for sensitive areas. While ambient noise guidelines recommend 40–50 decibels in silence zones like hospitals, fireworks are legally allowed up to 125 decibels, creating a significant mismatch that exposes patients to harmful sound levels.
• Risks to Patients and Critical Care Units - Experts warn that high-decibel fireworks near hospitals—especially those with neonatal intensive care units (NICUs)—can adversely affect infant brain development and disturb critically ill patients.
• Proximity Concerns and Infrastructure Gaps - Concerns have been raised about festivals like Thrissur Pooram, where fireworks occur close to hospitals, sometimes just minutes away.
• Broader Health Implications of Noise Pollution - According to the World Health Organization, noise pollution is the third most harmful environmental threat, after air and water pollution.

Noiseless Fireworks Alternatives: Safer and Sustainable Innovations

• In the wake of safety concerns and accidents, experts are advocating a transition to noiseless fireworks technologies, which can deliver similar visual appeal without the risks of explosions, high decibel noise, or large-scale hazards.
• Noiseless fireworks present a viable, safer, and eco-friendly alternative to traditional pyrotechnics, but require scaling, affordability, and policy support to replace conventional practices effectively.
• How Cold Spark Technology Works?
  • A key alternative is cold spark technology, which uses fine metal alloy powders (such as titanium and zirconium) instead of explosive combustion.
  • Devices like cold sparkulars heat these powders and eject them into the air, where they react with oxygen to produce bright, sparkler-like effects without noise.
  • Unlike traditional fireworks that rely on high-energy explosions, this method is controlled and significantly safer.
• Safety Advantages Over Traditional Fireworks
  • Noiseless alternatives operate at much lower temperatures (60–100°C) compared to conventional sparklers (around 1,200°C), greatly reducing the risk of burns and fire accidents.
  • They also eliminate loud sounds, making them safer for humans, animals, and sensitive environments like hospitals.
• Cost and Manufacturing Challenges
  • Despite their benefits, these alternatives are currently costlier and not widely scaled in India, with many products being imported.
  • However, experts highlight strong potential for domestic production, especially since the underlying technology is well understood.
• Expanding Creative Possibilities
  • Modern stage technologies demonstrate that noiseless systems can create visually rich displays, including coordinated spark fountains, light patterns, and sequential effects.
  • These systems can be arranged in clusters or mounted on structures to simulate large-scale aerial fireworks, offering equal or even superior visual experiences without the environmental and safety risks.

Way Forward: Transitioning to Safer, Noiseless Fireworks

• Experts recommend a phased shift toward noiseless technologies like cold spark systems, especially in high-risk and high-profile events.
• Cities like Delhi and festivals such as Thrissur Pooram can serve as pilot grounds for large-scale adoption, gradually replacing traditional fireworks.
• This transition would require institutional responsibility, particularly from local authorities, along with testing, scaling, and policy support to ensure safer and environmentally sustainable celebrations.
