Ammonia gas leak at seafood plant

Ammonia gas leak at a seafood processing plant in Tiruvallur, Tamil Nadu, resulted in 17 deaths, including 14 migrant workers from the Juang tribal community in Odisha.
The Juang are a Particularly Vulnerable Tribal Group (PVTG) residing in Keonjhar, Angul, and Dhenkanal districts of Odisha.
Factors driving migration among PVTGs include lack of local livelihood opportunities, low literacy rates, and inadequate implementation of development schemes.
The CAG report on 'Functioning of Micro Project Agencies' highlights that 25% of households in PVTG areas lack land ownership, and literacy rates remain low despite decades of intervention.
Institutional support for PVTGs includes the Juang Development Agency (JDA), Bonda Development Agency, and schemes like the Odisha PVTG Empowerment and Livelihood Improvement Programme (OPELIP) and PM-JANMAN Mission.
The Inter-State Migrant Workmen (Regulation of Employment and Conditions of Service) Act, 1979, mandates registration of workers, but its implementation remains a challenge.
Issues identified include the employment of minors in hazardous industries, use of fraudulent identification documents, and under-utilization of funds allocated under MGNREGS for tribal development.
