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
