"A spark ignited from the pump and triggered a reaction with her handphone," said Kuala Lumpur Fire and Rescue Department operations chief Samsol Maarif Saibani.
Firemen were alerted to the incident at 1.25pm and deployed five personnel from the Wangsa Maju Fire and Rescue Department.
Numerous signs are posted at petrol stations warning customers against using their phone there, especially when filling up petrol as it could trigger a fire. However, these signs are often ignored.
