GESR # Global essential safety requirement in Part 3

3.4 GESRs RELATED TO PERSONS IN THE lCU (CAR)

3.4.1 Strength and Size
The LeU (car) shall accommodate and support the rated load
and a reasonably foreseeable overload.

3.4.2 lCU (Car) Support/Suspension
Means shall be provided to support the fully loaded LeU (car)
and a reasonably foreseeable overload.

3.4.3 Overloaded lCU (Car)
Means shall be provided to prevent an overloaded LeU (car)
from attempting to leave a landing.

3.4.4 Falling from an lCU (Car)
Means shall be provided to prevent users from falling from the
LeU (car).

3.4.5 lCU (Car) Travel Path limits
The vertical travel of the LeU (car) shall be limited to prevent
the LeU (car) from uncontrolled running beyond the travel
path.

3.4.6 Uncontrolled, Unintended Movement of an lCU (Car)
Means shall be provided to limit uncontrolled or unintended
movement of the LeU (car).

3.4.7 lCU (Car) Collision with Objects in or beyond Travel Path
Means shall be provided to avoid collision of the LeU (car) with
any equipment in the travel path that could cause injuries to
users.

3.4.8 lCU (Car) Horizontal and Rotational Motion
Horizontal or rotational motion of the LeU (car) shall be limited
to sufficiently mitigate the risk of injury to users and elevator
personnel.

3.4.9 Change of Speed or Acceleration
Means shall be provided to ensure that any change of speed or
acceleration of the LeU (car) shall be limited to minimize the risk
of injury to the users.

3.4.10 Objects Falling on the lCU (Car)
Leu (car) users shall be protected from falling objects.

3.4.11 lCU (Car) Ventilation
Adequate ventilation shall be provided to the LeU (car).

3.4.12 Fire/Smoke in lCU (Car)
The interior of the LeU (car) shall be constructed of materials
that are fire-resistant and that develop a low level of smoke.

Cross-Referencing of GESRs in Part 3 and Elevator Sub-Systems

GESR # Global essential safety requirement in Part 3

3.4.13 lCU (Car) in Flooded Areas
Where there is a risk that the Leu (car) will descend into a
flooded area, means shall be provided to detect and prevent
descent into a flooded area.

3.4.14 Stopping Means Inside the lCU (Car)
Means located inside the Leu (car) of intentionally interrupting
the movement of the Leu (car) by the user shall be allowed
only, if necessary, on elevators with a partially enclosed LeU
(car) or elevators for special applications.

3.4.15 landing Indication
Means shall be provided to identify landings for users in the Leu
(car).

3.5 GESRs RELATED TO PERSONS IN WORKING AREAS

3.5.1 Working Space
Adequate and safe working space shall be provided.

3.5.2 Accessible Equipment
All elevator equipment requiring maintenance shall be safely
accessible to elevator personnel.

3.5.3 Access to and Egress from Working Spaces in the Hoistway
Access to and egress from working spaces in or beyond the
travel path shall be safe.

3.5.4 Strength of Working Areas
Means shall be provided to accommodate and support the
weight of elevator personnel and associated equipment in any
designated working area.

3.5.5 Restrictions on Equipment in Elevator Spaces
Only equipment related to the elevator installation or its
protection shall be placed in the space containing the elevator
equipment.

3.5.6 Falling from Working Areas
Means shall be provided to sufficiently mitigate the risk to
elevator personnel of falling from any working area.

3.5.7 lCU (Car) Movement under Control of Elevator Personnel
Only elevator personnel shall be provided with means to
prevent or to enable the movement of the Leu (car) when they
are in the travel path. When elevator personnel are within reach
of unprotected moving parts of the elevator, they shall be able
to prevent or activate movement of the elevator equipment.
