Last Saturday, a fire destroyed a house in Ahiatsikope, close to Dzodze in the Volta Region, killing Joyce Fianu, 26, and her nine-year-old niece, Christie Fianu.
Mavis Odor, the deceased's older sister, was taken for emergency treatment at a hospital in Accra after suffering severe burns.
The family's possessions and the roof of their house were both damaged by the fire.
According to Joy Ayim Ameyibor, the GNFS's Volta Regional Commander, Joyce sold petroleum products in bottles and other containers that were stored in the kitchen.
While she was cooking on a gas cylinder that fateful day, an "okada" rider arrived at the house to purchase fuel.
The fuel bottle she was holding slid off her hand as she was serving the client, bursting into flames.
As a result of the explosions from the other containers, the fire quickly spread to other areas of the house.
The attempts by neighbours to put out the fire and save the victims were ineffective.
He revealed that when members of the Dzodze-based GNFS team got on the site, the damage had already been done.
According to the Ghana National Fire Service (GNFS) crew that came to the scene, they saw the two dead bodies outdoors, close to the home's entrance.
He said that while the matter was being investigated, the remains had been transported to Saint Anthony Hospital in Dzodze.
Concerned about the region's growing tendency of selling fuel in containers, ACFO Ameyibor stated that the public and families were at grave risk from the practice.
According to ACFO Ameyibor, gasoline should never be kept at home.
In order to stop what he called the "micro-retailing of gasoline" in houses and on mounted stands in the neighbourhoods, he pleaded with the assemblies to act swiftly.
