30 C.F.R. Subpart O—Materials Storage and Handling
Title 30 - Mineral Resources
Supplies shall not be stacked or stored in a manner which creates tripping or fall-of-material hazards. (a) Bins, hoppers, silos, tanks, and surge piles, where loose unconsolidated materials are stored, handled or transferred shall be— (1) Equipped with mechanical devices or other effective means of handling materials so that during normal operations persons are not required to enter or work where they are exposed to entrapment by the caving or sliding of materials; and (2) Equipped with supply and discharge operating controls. The controls shall be located so that spills or overruns will not endanger persons. (b) Where persons are required to move around or over any facility listed in this standard, suitable walkways or passageways shall be provided. (c) Where persons are required to enter any facility listed in this standard for maintenance or inspection purposes, ladders, platforms, or staging shall be provided. No person shall enter the facility until the supply and discharge of materials have ceased and the supply and discharge equipment is locked out. Persons entering the facility shall wear a safety belt or harness equipped with a lifeline suitably fastened. A second person, similarly equipped, shall be stationed near where the lifeline is fastened and shall constantly adjust it or keep it tight as needed, with minimum slack. Materials that can create hazards if accidentally liberated from their containers shall be stored in a manner that minimizes the dangers. Containers holding hazardous materials must be of a type approved for such use by recognized agencies. [67 FR 42389, June 21, 2002] Compressed and liquid gas cylinders shall be secured in a safe manner. Valves on compressed gas cylinders shall be protected by covers when being transported or stored, and by a safe location when the cylinders are in use. (a) Taglines shall be attached to loads that may require steadying or guidance while suspended. (b) Hitches and slings used to hoist materials shall be suitable for the particular material handled. Persons shall stay clear of suspended loads. To protect personnel, material shall not be dropped from an overhead elevation until the drop area is first cleared of personnel and the area is then either guarded or a suitable warning is given. Persons shall not ride on loads being moved by cranes or derricks, nor shall they ride the hoisting hooks unless such method eliminates a greater hazard. Chemical substances, including concentrated acids and alkalies, shall be stored to prevent inadvertent contact with each other or with other substances, where such contact could cause a violent reaction or the liberation of harmful fumes or gases. Suitable warning shall be given before molten metal is poured and before a container of molten metal is moved. Operator-carrying overhead cranes shall be provided with— (a) Bumpers at each end of each rail; (b) Automatic switches to halt uptravel of the blocks before they strike the hoist; (c) Effective audible warning signals within easy reach of the operator; and (d) A means to lock out the disconnect switch. No person shall work from or travel on the bridge of an overhead crane unless the bridge is provided with substantial footwalks with toeboards and railings the length of the bridge. Fork and other similar types of lift trucks shall be operated with the— (a) Upright tilted back to steady and secure the load; (b) Load in the upgrade position when ascending or descending grades in excess of 10 percent; (c) Load not raised or lowered enroute except for minor adjustments; and (d) Load-engaging device downgrade when traveling unloaded on all grades.
