We a re deeply saddened by this incident. Our foremost thoughts are with all those affected — including members of our own team who were present at the site — and with their families, and we stand with them at this difficult time. Emergency response measures were initiated immediately at the site, with personnel from the Fire Brigade, the National Disaster Response Force (NDRF), a squad from the Indian Army, Senior Officials of the Company and Pimpri Chinchwad Municipal Corporation (“PCMC”), Disaster Response Teams and other emergency agencies reaching the location. Efforts are underway to search for and assist individuals who may be trapped under the debris. The number of persons injured or otherwise affected is being ascertained and will be confirmed by the concerned authorities. Our immediate priority is to support the ongoing rescue and relief operations and to extend all possible assistance to the Municipal Corporation, the local administration, emergency response agencies and other concerned authorities — including medical assistance to the injured and support to the families of those affected. We are also assisting in efforts to identify and account for all personnel who were present at the site. Based on the preliminary information available at this stage, a waste mound outside our facility, which had destabilized due to continuous and exceptionally heavy rainfall, collapsed during the afternoon and fell onto the administration building, resulting in the collapse of the structure. Prima facie, the incident appears to have been triggered by the unprecedented weather conditions that led to the destabilization of the waste mound. The region had been experiencing continuous and exceptionally intense rainfall in the preceding period. The plant was undergoing a scheduled maintenance shutdown at the time of the incident, which also meant that a limited number of operating personnel were present on site. Further, based on the information currently available, no immediate material impact on the Company’s operations has been identified.
