The TT National Petroleum Marketing Company Ltd (NP) is advising the public to test their gas cylinders once they enter their home or business place, following the death of a Diggity Trace woman over the weekend after her tank exploded at her house.

A release said once purchased, customers should perform a "soapy water test" on the connections between the regulator and valve, the regulator and the hose, and the hose and stove before using it.

"In the event that a gas leak is suspected, customers are advised to immediately disconnect the cylinder and remove to a safe and secure location away from the premises."
