Before attempting a ramp the following basic safety rules should be
considered
：
1.
Surface of the ramp: Is it too slippery ?
2. Degree of incline: Is it too steep to attempt alone ?
3. Length of ramp: Is it too long for your endurance ?
4. Obstacles: Are there any obstacles on the ramp that would
necessitate an attendants assistance ?
Assistance is always recommended when going up or down steep
inclines.
In order to prevent loss of steering control, or the possibility of tipping over back-
wards, an attendant is recommended when going up inclines greater than 10% (30
cm elevation on a 300 cm ramp).
If it becomes necessary to stop when going up an incline, special care must be
taken to avoid abrupt or sudden forward movement when you resume propelling
the chair so as to avoid forces which could tip the chair backwards.
Always keep the chair under control when going down a ramp or incline. Speed
should be controlled at all times.
When a chair is being attended by a carer and a kerb is encountered care should
be taken to prevent the user being thrown forward
：
1.
Go down the kerb rear wheels first, making sure that the user is square to
the kerb so that the rear wheels go down together.
2. Go up a kerb frontward with both front wheels up together.
3. Avoid going up multiple steps.
4. Avoid using escalators. Use the elevator.
NOTE : As with all adjustable wheelchairs, operation at the extremes
of adjustment may affect handling and performance.
