Section 13.172 - Platforms(a)Use. It is recommended that platforms be so erected in a free space at least equal in surface to a quarter of the floor space of the building. It is recommended to leave between platforms and the outer walls either a free space or a space covered by slats 2 to 3 feet wide, which is calculated by adding the area of this space to the free space.(b)Distance. The distance of the larger platforms from the floor and from each other shall be 10 feet in so far as is possible and practicable. For smaller platforms a shorter distance is permitted, if it does not interfere with the ventilation of the building.(c)Kettles. On top of melting kettles and distilling apparatus, only such platforms shall be built as are absolutely necessary for the proper handling of the apparatus. It is recommended that care be taken in constructing an apparatus so that vapors and gases cannot escape and injure those obliged to be upon the platform.(d)Construction. Platforms on which work is regularly carried on with nitro and amido compounds shall be light and easy to clean, and covered with sheet lead where advisable.(e)Railings and toe boards. Platforms shall be equipped with railings and toe boards in accordance with the provisions of Chapter 47, Subchapter G (relating to railings, toeboards, open-sided floors, platforms and runways).
