1.26 A ramped access will satisfy Requirement M1 or M2 if:
a. it is either readily apparent or the approach to it is clearly sign-posted;
b. the gradient of a ramp flight and its going between landings are in accordance with Table 1 and Diagram 3;
c. no flight has a going greater than 10m, or a rise of more than 500mm;
d. there is an alternative means of access for wheelchair users, e.g. a lift, when the total rise is greater than 2m;
e. it has a surface width between walls, upstands or kerbs of at least 1.5m;
f. the ramp surface is slip resistant, especially when wet, and of a colour that contrasts visually with that of the landings;
g. the frictional characteristics of the ramp and landing surfaces are similar;
h. there is a landing at the foot and head of the ramp at least 1.2m long and clear of any door swings or other obstructions;
i. any intermediate landings are at least 1.5m long and clear of any door swings or other obstructions;
j. intermediate landings at least 1800mm wide and 1800mm long are provided as passing places when it is not possible for a wheelchair user to see from one end of the ramp to the other or the ramp has three flights or more;
k. all landings are level, subject to a maximum gradient of 1:60 along their length and a maximum cross fall gradient of 1:40;
l. there is a handrail on both sides;
m. there is a kerb on the open side of any ramp or landing at least 100mm high, which contrasts visually with the ramp or landing in addition to any guarding required under Part K;
n. clearly sign-posted steps are provided, in addition, when the rise of the ramp is greater than 300mm (equivalent to 2 x 150mm steps).
