The safety policies of...Vedanta Resources are set to come under scrutiny after an accident at one of its sites in India killed as many as 100 people on Wednesday... The death toll is expected to rise after a chimney collapsed at an aluminium plant [owned by Vedanta subsidiary Bharat Aluminium Co. (BALCO)] in which Vedanta has a 51 per cent stake through its subsidiary Sterlite Industries. Sterlite is the builder at the site in Korba, in the central India state of Chhattisgarh... Rajeev Sharma, the south Asian head of the Building and Woodworkers' International union, said that the accident was bad, even by India's poor safety standards... Vedanta, which claims to benefit from "relatively low cost of operations and large and inexpensive labour and talent pools", expressed regret but declined to comment further.
