Substandard CNG-cylinders pose threat to life

No icon Health Crime

Health Desk: Oct 30, 2017--- A section of automobile workshops across the country is installing substandard cylinders in CNG-powered vehicles, posing a serious threat to the safety of passengers.

Automobile workshops which have mushroomed at different parts of the capital are involved with such illegal practice exploiting the lack of monitoring by the authorities concerned,  according to the sources.

Sources at Rupantarita Prakritik Gas Company Limited (RPGCL), said some 180 CNG-conversion centres across the country are authorised to install CNG cylinders in  vehicles. But, many errant workshops are fitting low-quality CNG cylinders which are highly vulnerable to accident.

Substandard cylinders are often made from metal electric poles, cylinders of fire extinguishers, oxygen cylinders, and some other kind of unauthorised materials.

Admitting the fact, Engineer Wasim Safkat Khan, deputy manager of RPGCL, told the daily sun  some illegal workshops are installing  unauthorised CNG cylinders at different places of the capital, ignoring the safety of passengers.

According to the rules and regulation, NGV (Natural Gas Vehicle) cylinders are meant for the CNG-run automobiles, but cylinders like oxygen cylinders, acetylene gas cylinders, rejected cylinders and counterfeit cylinders are being used for CNG-run vehicles.

Sector insiders said CNG cylinders are quite expensive and usually imported from foreign countries, including India, Brazil, Argentina, and South Korea.

A proper CNG conversion needs Tk 60,000- 75,000 while the cost of a substandard conversion ranges between Tk 10,000 and Tk 20,000.

As a result, dishonest vehicle owners are using substandard and unauthorised cylinders.According to the rules made by RPGCL, a CNG cylinder must be able to withstand pressure of 3,000 pounds per square inch (psi). But the substandard cylinders being used in converted automobiles can barely withstand 1,000psi of pressure as the cylinders are at risk of blast.
