Examiner: Nothing Wrong With Tah Ching Rd Lift

Independent authorised examiner for the Tah Ching Road lift mishap found that there was nothing wrong with the lift in which an 85-year-old woman lost her left hand.

Citing findings from the examiner’s investigation report submitted on the 9 Oct lift tragedy, the Building and Construction Authority (BCA) said yesterday (6 Nov) that a dog leash which was looped around Madam Khoo Bee Hua's left wrist was simply too narrow for sensors to detect and reopen the doors.

The lift doors are supposed to reopen if sensors detect an obstacle 10mm or wider between them, but were not designed to register thinner objects such as the 2mm-thick leash for Madam Khoo's dog.

As the lift went up, the leash could have pulled her hand through a gap in the doors, and the hand was severed before the lift could come to a halt.

After the incident, the authorised examiner analysed evidence such as closed-circuit television footage and a specialist medical report, and interviewed the victim. He also inspected the lift in detail and performed tests and simulations of the accident.

BCA said it also conducted its own independent investigation, and its findings were consistent with the examiner's.

The BCA said that it plans to boost public awareness on lift safety through measures such as distributing posters to town councils and building owners. These will caution users not to put their hands between the doors and to keep a close eye on their pets, for instance.
