OVERSIDE WORK RAIL SYSTEM SIZE 1 - B10465 iss.1
|
5
A device permits the locking of the car to any of the locking holes along the rail, so that when lowering or lifting
in the vertical plane, the car does not inadvertently slide along the rail in response to lowering or lifting
movement, enabling the person to maintain stability and to control their position.
A second car, which is joined to the main car, provides the attachment point for a fall-arrest system. The
fall-arrest system prevents a fall to the ground, substantial platform, water or other substance should the
lifting-lowering device or rope fail. Use of the fall-arrest system necessitates the wearing of a full body safety
harness by the worker.
The rail is also tested and rated for rescue purposes - to allow a second person to lower themselves from an
additional pair of cars on the track in order to rescue a worker whohas become incapacitated, or whose fall has
been arrested and cannot get back to a place of safety on their own.
An additional single car can also be used to secure a small tool bag and containers of cleaning agents, to assist
in any maintenance work.
3 - Rating
In normal operation the system is designed for use by one person with a mass,(including clothing and
attached equipment), not in excess of 125 kg. No more than one person may be connected to a two-car
assembly at any one time. The fall-arrest system must be connected to the car with the spring loaded locking
plunger and the lifting-lowering system must be connected to the other car.
In order to assist in the rescue of a person whose fall has been arrested by the fall-arrest system, or has become
incapacitated and is not able to self-recover, a second person may suspend themselves and descend to render
assistance from an additional pair of cars. The system has been tested and has been rated for this situation,
so that two persons, each not in excess of 125 kg, may be attached to the rail in an emergency/rescue
situation.
