The apex court said the laboratory test would indicate the toxicity index of materials used for PVC flooring, vinyl covering for seats and berths, cushioning material for seats and berths and curtain fabric.
A bench headed by Chief Justice H L Dattu asked the Centre and the railways to place the samples of the materials used in the coaches manufactured in 2013-14 and indicate the laboratory where the test can be carried out.
The court was hearing a PIL which alleged that use of sub- standard materials for furnishing interiors of coaches has caused asphyxiation deaths due to inhalation of toxic gases by passengers during fire accidents in trains.
It passed the order after going through the responses of departments concerned of the railways --Railway Designs and Standards Organisation (RDSO), Rail India Technical and Economic Services (RITES) Ltd, two rail Coach Factories of Kapurthala in Punjab and Lalganj, Rae Bareli in Uttar Pradesh and Integral Coach Factory, Chennai.
The petition filed in February this year had raised issues relating to the death of people due to fire accidents in trains, which were happening time and again. He had cited statistics of recent fire accidents in trains in which a large number of passengers had lost their lives.
"These deaths are caused due to asphyxiation by inhalation of toxic gases, engulfing the railways' passenger coaches. This toxicity is caused from poisonous gases released by the inferior and sub-standard quality of the materials used by the Indian Railways in the interior furnishings, which are all around the passengers," the petition claimed.
