<br />... <br /> <br />Cross Construction Services, Inc. <br />@ 2011 DEMOLITION SAFETY PLAN <br />CROSS CONSTRUCTION SERVICES, INC. <br /> <br />12. MECHANICAL DEMOLITION WITH CRANE <br /> <br />1. During the demolition operations, when balling or clamming are being performed. Only <br />those workers necessary for the performance of the operations will be permitted in this <br />area at any other time. <br /> <br />2. The crane boom and load line will be as short as possible. <br /> <br />3. The weight of the demolition ball will not exceed 50 percent of the crane's rated load, based <br />on the length of the boom and the maximum angle of the operation at which the <br />demolition ball will be used, or it will not exceed 25 percent of the nominal breaking <br />strength of the line by which it is suspended, whichever results in a lesser value. <br /> <br />4. The ball will be attached to the load line with a swivel-type connection to prevent twisting of <br />the load line, and will be attached by positive means in such manner that the weight <br />cannot become aCcidentally disconnected. <br /> <br />5. When pulling over walls or portions thereof, all steel members affected will have been <br />previously cut free. <br /> <br />(, <br /> <br />6. All roof cornices or other such ornamental stonework will be removed prior to pulling walls <br />over. <br /> <br />7. During demolition, continuing inspections by a competent person will be made as the work <br />progresses to detect hazards resulting from weakened or deteriorated floors, or walls, <br />or loosened material. <br /> <br />8. No employee will be permitted to work where such hazards exist until they are corrected by <br />shoring, bracing, or other effective means. <br /> <br />13. SPECIAL STRUCTURES DEMOLITION <br /> <br />Safe work practices when demolishing a chimney, stack, silo, or cooling tower will include the <br />following procedures: <br />Inspection and planning: <br /> <br />1. When preparing to demolish any chimney, stack, silo, or cooling tower, the first step will be <br />a careful, detailed inspection of the structure by an experienced person. <br /> <br />2. If possible, architectural/engineering drawings will be consulted, <br /> <br />3. Particular attention will be paid to the condition of the chimney or stack. <br /> <br />c <br /> <br />4. Workers will be on the lookout for any structural defects such as weak or acid-laden mortar <br />joints, and any cracks or openings. <br /> <br />13 <br />
