A disabled woman’s electric wheelchair burst into flames in Sau Mau Ping, Kowloon, on the weekend, but no one was injured. The 58-year-old woman was riding her power wheelchair in Shun Tin Estate in the early hours of Sunday when some passers-by observed smoke, Sing Tao Daily reported.

They helped the woman get out of the wheelchair and notified Hong Kong police. The woman was not injured but the wheelchair was engulfed in flames.

Firefighters put out the blaze in 10 minutes. After an initial investigation, they believed that the fire was caused by a short circuit.

In September last year, an electric wheelchair used by an 83-year-old man exploded after its power source had been recharging for 20 hours. He was saved by a domestic worker, Apple Daily reported.

Lo Kok-keung, a former engineer at Hong Kong Polytechnic University’s department of mechanical engineering, advised users and caretakers to check their electrical wheelchairs regularly for overheating problems.
