The Government Analyst's Department has confirmed that the reason for the recent explosion of domestic gas cylinders in several places is due to changes in their composition. Several gas cylinder explosions have been reported in various parts of the island during the past two weeks.
The report also states that the companies have changed the composition of the gas without proper approval.
As Sri Lanka is a tropical country, the gas composition should have a low percentage of propane and a high percentage of butane.
Following the Government Analyst's report that the cause of the recent explosions in Colombo, Weligama and Kandy was a gas leak, the Sri Lanka Standards Institution has been criticized for not taking action on complaints received from the general public regarding gas cylinder leaks.
Since last April, Litro and Laugfs have changed the gas composition of a cylinder from Butane 80: Propane 20 to Butane and Propane 50:50, respectively, without SLSI approval. This is said to be the reason for the complaints received that the valves in the cylinders are leaking.
Former Director of the Consumer Affairs Authority Thushan Gunawardena recently stated that Ministers Bandula Gunawardena and Lasantha Alagiyawanna did not take any action to inform him that this could be a serious accident and that it has now been proven to be true and could result in loss of life.
