<br />() <br /> <br />(: <br /> <br />(, <br /> <br />Cross Construction Services, Inc. <br />@ 2011 DEMOLITION SAFETY PLAN <br />, CROSS CONSTRUCTION SERVICES. INC. <br /> <br />14. The supervisor will make careful inspection of the masonry as to the safety of the <br />alternative. It is essential that the masonry of the chimney be in good enough condition <br />to support the bracket scaffold. <br /> <br />15. The area around the chimney will be roped off or barricaded and secured with appropriate <br />warning signs posted. No unauthorized entry will be permitted to this area. It is also <br />good practice to keep a worker, i.e., a supervisor, operating engineer, another worker, <br />or a "safety person," on the ground with a form of communication to the workers above. <br />16. Special attention will be paid to weather conditions when working on a chimney. No work <br />will be done during inclement weather such as during lightning or high wind situations. <br />The work site will be wet down, as needed, to control dust. <br /> <br />14. DEBRIS CLEARANCE <br /> <br />If debris is dropped inside the shaft, it can be removed through an opening in the chimney at <br />grade level. <br /> <br />1. The opening at grade will be kept relatively small in order not to weaken the structure. <br /> <br />2. If a larger opening is desired, a professional engineer will be consulted. <br /> <br />3. When removing debris by hand, an overhead canopy of adequate strength will be provided. <br /> <br />4. If machines are used for removal of debris, proper overhead protection for the operator will <br />be used. <br /> <br />5. Excessive debris will not be allowed to accumulate inside or outside the shaft of the <br />chimney as the excess weight of the debris can impose pressure on the wall of the <br />structure and might cause the shaft to collapse. <br /> <br />6. The foreman will determine when debris is to be removed, halt all demolition during debris <br />removal, and make sure the area is clear of cleanup workers before continuing <br />demolition. <br /> <br />15. DEMOLITION BY DELIBERATE COLLAPSE <br /> <br />1. Another method of demolishing a structures, chimneys, or stacks are by deliberate collapse. <br /> <br />2. Deliberate collapse requires extensive planning and experienced personnel, and will be <br />used only when conditions are favorable. <br /> <br />o <br />3. There will be a clear space for the fall of the structure of at least 45 on each side of the <br />intended fall line and 1 % times the total height of the chimney. Considerable vibration <br />will be set up when the chimney falls, so there will be no sewers or underground <br />services on the line of the fall. <br /> <br />15 <br />
