Sri Lanka, Nov. 25 -- The Government Analyst's report confirms that the reason for the explosion of gas tanks was the change in the composition of the gas.

Government Analyst reports state that the cause of the recent explosions in Colombo, Weligama and Kandy was gas leaks.

Litro first decided to change the composition of LP gas for domestic use in Sri Lanka without giving a clear reason, reducing the gas volume in its cylinder and adding a new brand to it.

Since last April, Litro and Laugfs has changed the gas composition of a cylinder to butane and propane 50:50 without the approval of the Sri Lanka Standards Institution. It's changing the composition of the less flammable butane 80 and the more flammable propane 20.

To justify the move, Litro's management at the time argued that day-to-day operations would require lower gas consumption due to the release of more heat through this gas composition change.

However, there have been repeated complaints from consumers to the Sri Lanka Standards Institution that such a change in gas composition could create a serious hazard.

The Sri Lanka Standards Institution has also been accused of not taking positive action in this regard.

However, in the face of persistent protests in the media and society over the situation, both gas companies had to withdraw their new ventures.

Surprisingly, no laboratory tests have yet been performed to determine whether they have reversed their gas composition.

Due to this, the request made by Dr. Siddhika Senaratne of the Sri Lanka Standards Institution to bring in regulations to introduce a standard composition for LP gas to protect the lives of gas consumers was also not given due consideration by these companies.

Meanwhile, there have been reports of gas cylinder valves leaking from various parts of the island in the recent past.

An official of the Government Analyst's Department said that he was confident that all the explosions were due to changes in the gas composition.

"We predicted such dangers in June this year. Sri Lanka is a tropical country. Our average temperature is higher, so the LP gas composition should have a lower percentage of propane and a higher percentage of butane," he added.

However, when asked why Anil Koswatte, the former chairman of Litro Gas, changed the composition of butane and propane LP gas from 80:20 to 50:50, he did not have a clear answer.

The spokesperson further alleged that the gas companies had endangered the lives of the citizens by changing the composition to make more profits and that the Minister of State for Consumer Protection Lasantha Alagiyawanna had also failed to take appropriate action under Section 72 of the Consumer Protection Ordinance.
