Where drainage is required, the slope shall not exceed 1 in 35.平臺。平臺必須相對水平。若需要排水，則坡度不得超過1:35。Where the level of a platform above an adjacent platform or floor is not more than 300 mm, access from one level to the other may be gained without the provision of an intermediate step. Where the change of level is greater than 300 mmbut does not exceed 450 mm, one intermediate step shall be provided. Access between adjacent levels where the difference exceeds 450 mm shall be in accordance with the requirements of Section 4 or Section 5 or by a sloping walkway in accordance with Clause .若平臺高度高出高于鄰近平臺或地板的距離少于300毫米以下，則不依靠中間踏步也可從一個層面高度進(jìn)入另一高度層面。如果高度差層高高于大于300毫米，但不超過450毫米，則必須提供配備中間踏步。距離高度差超過450毫米的相鄰各層之間的通行通道必須符合遵照第四章或第五章的要求。 Continuous walkways Walkways may have a slope up to and including 20 degrees.
