Speaking to Khaleej Times, Eng. Al Kaar said: “We often hear about a number of tragic accidents caused by sudden blast of gas cylinder and in many cases lots of innocent people have paid their lives, but we never asked about the main reason causing such blasts.”

“There are several reasons behind gas cylinder blast that people must keep in mind. A leak in the cylinder pipeline can be one of the strong reasons causing gas cylinder blast. Another reason is human error as majority of people including housewives and restaurant owners are leaving the cylinder valve open during the night when not in use. People must replace the hose which is the connection between the gas cylinder and the oven burner once they see any damage in the connection,” he said.

Eng. Al Kaar said a big majority of people think that the gas cylinders are explosive bombs placed in their homes but this is only true if they are recklessly using the gas cylinder even if they notice any kind of leak or keep the oven valve open 24 hours a day. The oven valve of any cylinder should be closed after each usage. The gas in the cooking gas cylinder is about 5 to 6 bars and the cylinder burst pressure is 27 to 28 bars.

Urging Eng. Al Kaar to offer more comprehensive information about the safest ways of handling and using the gas cylinders without the fear of any gas cylinder blast, he said: “Consumers must always close the valve of the cylinder after each usage of the gas cylinder, regularly check pressure regulator and the hose of the cylinder that connects the gas cylinder with the oven warm burner. The hose must be replaced at least once a year and the cylinder must be placed in a highly ventilated area without being exposed to direct heat or sun rays. They should always check the expiry date of the gas cylinder as per the regulations the life of the gas cylinder is 15 year.”

“To personally check whether the gas cylinder is safe or leaking, it should be rubbed using liquid soap. In case bubbles are formed, it means that the cylinder is leaking,” he said, stressing on the importance of installing a fire extinguisher in the kitchen while being aware of using it.

Eng. Al Kaar advised people and housewives to immediately open the hose and the doors of the house in case a gas cylinder is leaking and never to use any heat source or match while in doubt that there is leakage.
