Lift Elevator Safety
New modern elevators are designed to be fail-safe and user-friendly to prevent accidents. The Singapore Lift and Escalator Contractors and Manufacturers Association (SLECMA) have set up a safety committee to create awareness in the usage of elevators and escalators.
The association ensures the lifts are installed under the following guidelines:
- Prevent any part of the passenger from danger at the leading edges.
- Prevent closing of elevator doors when passengers approach, stand near or at the door edge, even from a flat angle.
- 2.5 cm from lift cabin.
- 3.0 cm from lift lobby.
- 50 cm for door horizontal sensing.
- 1.8 m for door vertical sensing.
- Should not fail if any fail-safe related to safety device fails.
- Response time of the sensing device should be less than 50 milliseconds.
- Stopping time of the door should be less than 200 milliseconds.
- The voice & motor noise within control requirements.
- Smoke Control
- Reliability of Electrical Power Supply
- Effects of Fire
- Effects of Water
- Effects of Electro-Radiation

Famous quotes containing the words lift, elevator and/or safety:
“And if thou wilt make me an altar of stone, thou shalt not build it of hewn stone: for if thou lift up thy tool upon it, thou hast polluted it.”

“The indifferent clerk he knowing what was going to happen
The lobby zombies they knowing what
The whistling elevator man he knowing
The winking bellboy knowing
Everybody knowing! I’d be almost inclined not to do anything!”
—Gregory Corso (b. 1930)
“There was only one catch and that was Catch-22, which specified that a concern for one’s own safety in the face of dangers that were real and immediate was the process of a rational mind.... Orr would be crazy to fly more missions and sane if he didn’t, but if he was sane he had to fly them. If he flew them he was crazy and didn’t have to; but if he didn’t want to he was sane and had to.”
—Joseph Heller (b. 1923)
