The 58-year-old building, situated on Jalan Gasing, is a familiar landmark for tens of thousands of motorists using the busy highway.
The original building with its aluminium-grille facade underwent a facelift several years ago to reflect the retirement fund’s corporate image.
An ambulance was seen on the Federal Highway, heading towards Kuala Lumpur. Meanwhile, personnel from the Fire and Rescue Department are attempting to put out the blaze.
