Just yesterday one explosion in firecracker unit near Thoothukudi, and now this ammonia leak. 🤔 Our industrial safety standards need a complete overhaul. Workers are risking their lives daily. Government should impose strict penalties on such companies and ensure regular health check-ups for affected people.

Kudos to NDRF team for quick response. But why do these leaks happen so often? CBRN deployment should be a last resort, not a routine measure. Factory owners need to maintain proper safety protocols. Also, the media should highlight the health impacts on surrounding villages near Periyapalayam.

I live near Tiruvallur, and such incidents really scare local residents. The ammonia gas can cause serious lung damage if exposed for long. District administration should immediately provide compensation to victims and conduct awareness campaigns about what to do during such gas leaks. Stay safe everyone!

Sad to read about the woman who died in the firecracker factory explosion 😢 Mariammal's family must be devastated. These small-scale factories operate without proper safety measures just to save costs. The government should make it mandatory for all such units to have emergency response plans and regular inspections. RIP.

As a safety professional, I know ammonia leaks are common in seafood processing plants due to refrigeration systems. The key is early detection and proper ventilation. Glad NDRF deployed the CBRN team fast, but the company should have had its own safety protocols. Hope those 20 affected recover fully.
