R 408.10591 Operations use.

Rule 591. (1) Working platforms shall not be loaded in excess of the rated load as stated on the platform load rating plate. (2) Employees shall be prohibited from working on snow, ice, or other slippery material that covers a platform, except to remove such materials. (3) Adequate precautions shall be taken to protect the platform, wire ropes, and lifelines from damage due to acids or other corrosive substances. The precautions taken shall be in accordance with the recommendations of the corrosive substance producer, supplier, platform manufacturer, or other equivalent information sources. Platform members that have been exposed to acids or other corrosive substances shall be washed down after each use with a neutralizing solution at a frequency recommended by the corrosive substance producer or supplier. (4) Platform members, wire ropes, and lifelines shall be protected when using a heat-producing process. Wire ropes and lifelines that have been contacted by the heat-producing process shall be considered to be permanently damaged and shall not be used. (5) A platform shall not be operated in winds of more than 25 miles per hour (40.2 km/hr), except to move the platform from an operating to a storage position. Wind speed shall be determined based on the best available information, which includes on-site anemometer readings and local weather forecasts that predict wind velocities for the area. (6) On exterior installations, an anemometer shall be mounted on the platform to determine on-site wind velocities before and during use of the platform. The anemometer may be a portable (hand-held) unit that is temporarily mounted during platform use. (7) Tools, materials, and debris that are not related to the work in progress shall not be allowed to accumulate on platforms. Stabilizer ties shall be located so as to allow unencumbered passage along the full length of the platform and shall be of such length so as not to become entangled in rollers, hoists, or other machinery.
