The safety standards for wheelchair ramps are designed to ensure that wheelchair users can use the ramps safely and conveniently. The following are specific safety standards summarized based on the search results:
1. Slope requirements
- The transverse slope should not be greater than 1:50.
- The longitudinal slope should not be greater than 1:12. When conditions are limited and the height difference between the starting and ending points of the slope section is not greater than 150mm, the longitudinal slope should not be greater than 1:10.
2. Lifting height
- The lifting height of each section of the ramp should not be greater than 750mm. This helps prevent users from being unable to operate the wheelchair due to physical exhaustion, thereby reducing safety hazards.
3. Clear width
- The clear width of the wheelchair ramp should not be less than 1.20m. This width can meet the use needs of different types of wheelchairs.
4. Platform requirements
- The clear width of the starting point, end point and rest platform of the wheelchair ramp should not be less than the clear width of the ramp, and the horizontal length should not be less than 1.50m. This ensures that wheelchair users have a horizontal space to adjust the direction of the wheelchair or take a short rest before entering the ramp and after completing the journey.
5. Handrail Setting
- When the height of the wheelchair ramp is greater than 300mm and the longitudinal slope is greater than 1:20, handrails should be set on both sides, and the handrails of the ramp and the rest platform should be kept continuous. The presence of handrails can increase the user's sense of security and stability.
6. Safety blocking measures
- Safety blocking measures should be taken on the air side of the wheelchair ramp with handrails. These measures may include widening the ramp surface and platform surface 300mm outward from the outer edge of the handrail, or setting a safety stopper with a height of not less than 50mm on the edge of the ramp and platform.
7. Design shape
- The wheelchair ramp should be designed to be straight or concave (return shape) to ensure that users can pass smoothly.
8. Double handrails and safety guards
- Double handrails should be installed on both sides of the wheelchair ramp, and a 100mm high safety guard should be installed at the bottom of the handrail to increase the safety of the user.
9. Resting platform
- In the case of a long ramp, a resting platform should be set up. This helps users to get a short rest after using the ramp for a long time, thereby reducing fatigue and safety hazards.
In summary, the safety standards for wheelchair ramps cover many aspects such as slope, width, height, handrail settings, and safety blocking measures. The implementation of these standards can effectively improve the safety of wheelchair ramps and ensure that wheelchair users can use the ramps conveniently and safely.
