Occupational Health & Safety Health & Safety Performance

LTIFR for the year was 0.81 as compared to 0.97 a year ago. It is with deep sadness that we report the regret of four colleagues (Business partners) in work-related incidents at our operations. These incidents happened despite continuous efforts to eliminate fatalities and attain zero-harm work environment. Thorough investigations were conducted to identify the causes of these incidents and to share lessons learnt across HZL operations, with the aim of preventing repeat or similar incidents.

There has been enhanced leadership focus on incident reporting, incident categorisation & incident investigation along with greater focus on horizontal deployment of learnings across HZL and critical risk management.

During the year, the Company commissioned first made-in-India emergency escape route (staircase type) in at Rajpura Dariba Underground Mine as well as underground rescue station at Rampura Agucha Mine, both of which will significantly improve the response time in case of an emergency. Qualitative and Quantitative Exposure Assessment is completed for all units and exposure mitigation plan is developed. 22 Digitized safety modules were launched for easy understanding of safety standard requirements.

Demonstrating the highest standards of health and safety management during the year, Chanderiya CPP and Debari both received the prestigious ‘Sword of Honour? from British Safety Council for showing excellence in the management of health and safety risks at work. Kayad Mine was also awarded the National Safety Award from the Government of India for the longest accident-free operations in the metal and mining sector as well as for the lowest injury frequency rate.


During FY 2021-22, waste recycling increased marginally to 31% (FY 2020-21: 30%), and water recycling rate increased to 44% in (FY 2020-21: 39%). Specific energy consumption for FY2021-22 was 48 GJ/MT of metal (FY 2020-21: 51 GJ/MT).

Hindustan Zinc commits to ‘Long-term target to reach net-zero emissions by 2050? in alignment with Science Based Targets initiative (SBTi) aiming to have clearly defined path to reduce emissions in line with the Paris Agreement goals. Company has made notable technological advancements in energy conservation. Zinc Smelter Debari has revamped the cell house and eliminated current losses through electrolytic cells by successfully replacing 600+ concrete cells with poly-concrete cells. As a result, the power rating has improved. Additionally, the turbine revamping project is certified as a carbon reduction project by VERRA (the world?s most widely used voluntary GHG program) resulting in avoidance of GHG emissions of 270,000 tCO2e per year. For decarbonizing the future of Indian mining, Hindustan Zinc has partnered with leading global manufacturers for introducing Battery Electrical Vehicles (BEVs) in its underground mines. All units of HZL are certified as ISO 50001 (Energy Management system).

Hindustan Zinc has published its first TCFD (Task Force on Climate-related financial disclosure) report during the year, adapting the TCFD framework for climate change risk and opportunity disclosure.
