In assembly areas, what is the maximum slope for exit ramps according to RA 9514?

The maximum slope for exit ramps in assembly areas as stated in RA 9514 is 1:12. This designation indicates that for every 12 units of horizontal distance, the ramp should rise no more than 1 unit. This specific slope is crucial in ensuring that ramps are accessible and safe for individuals using mobility aids, such as wheelchairs, as well as for general use by the public during an evacuation process. A slope of 1:12 provides a balance between safety and functionality, ensuring that the ramp is not too steep to navigate.

Ramps with steeper slopes, like 1:10, would pose challenges for individuals with limited mobility or those carrying heavy objects, increasing the risk of accidents during evacuation. Conversely, a slope of 1:14 or 1:16 would not meet the requirements for emergency escape routes, as they might be too gentle, affecting the efficiency of the exit during an emergency. Hence, the adherence to a 1:12 slope ensures compliance with safety regulations while promoting universal accessibility.
