Singapore Lift's Have 1/1000 Chance of Getting Stuck in a Blackout? Or Not....

Read this article from Channel NewsAsia. Some Excerpts of it

SINGAPORE : Tuesday night's blackout affected some 21 lifts of the total of 16,700 in Singapore's HDB estates.
......
Town Councils, responsible for the maintenance of the lifts, pointed to the malfunction of the rescue device as the main culprit.

That is despite the required monthly servicing of all HDB lifts, which includes testing this device.

Lights and fans were also shut down, leaving some trapped in complete darkness and limited ventilation.

Emergency batteries stored in the control room are meant to keep the lights and fans on for at least 4 hours, but they failed to work.

Still, the largest lift company in the market is satisfied with the failure rate during the blackout.

"The reliability of this device is very high and chances of failure are very small," said Phuah Cheng Kok, Executive Vice-President, Fujitec.

"Because it is an electro-mechanical device that's dependent on a battery, there is still a small chance that this device can fail because of age or equipment failure."

He added: "So looking at the number of calls that were received during the blackout, out of the whole of Singapore, therer were only 20 cases, which makes it one in every 1,000 chance of failure. So it's a very good statistic." - CNA
