§ 25.54. Cages.
(a) Means of escape. Means of escape shall be provided for operators of hot metal cranes. This shall consist of a walkway accessible from the cage when in any position, or some other approved arrangement.
(b) Location and size of cages. The cage of the operator shall be located at a place from which signals may be clearly understood, and shall be securely fastened in place and well braced to minimize vibration. The cage shall be large enough to allow ample room for the control equipment and the operator. The operator may not be required to step over an open space of more than 18 inches when entering the cage.
(c) Fire extinguisher. An approved type fire extinguisher shall be carried in the cage.
(d) Warning device. In establishments where continuous loud noises prevail, such as caused by the operation of pneumatic tools, steam exhausts from boilers, and the like, audible type signalling devices shall be installed on cranes or one or more employes shall be placed on the floor for each crane operated to warn other employes of the approach of a crane with a load. If there are more than two cranes on the same runway or within the same building structure, signalling devices may not be required if a man is placed on the floor for each crane to give warning to other employes of the approach of a crane with a load.
(e) Protection from heat. Cages of cranes subjected to heat from below shall be of noncombustible construction and shall have a steel or aluminum plate shield not less than 6 inches below the bottom of the floor of the cage. If necessary an approved heat insulating material shall be provided in this space.
(f) Outside cages. Outside crane cages shall be enclosed and properly heated. There shall be windows on three sides of the cage. The windows in the front and the side opposite the door shall be the full width of the cage.
