PART 20 DEMOLITION

 

R 408.42031  Demolition generally.

Rule 2031. (1) Before the start of a demolition operation, an employer shall ensure that all of the following are done:

(a)     An engineering survey of the structure and equipment is conducted by a competent person knowledgeable in demolition to determine all of the following:

(i)   The condition of the foundation, roof, walls, and floors.

(ii)   Whether any adjacent structure will be affected by the demolition.

(iii)   The utility service entering the building.

(iv)   Any other conditions and equipment affecting the safety of an employee.

(b)    An employer shall ensure that there is a written report of the survey at the field office until the completion of the job. The report shall include information such as the name of the person conducting the survey, date of the survey, and hazardous substances and dangerous conditions found and their location. In an emergency situation, a survey is not required. If a field office does not exist at the demolition site, then an employer shall file the written report of the survey at the employer’s main office.

(c)    An employer shall inform utility companies of the planned demolition. An employer shall ensure that utility services are shut off, capped, or otherwise protected from damage, except as specified in subrule (2) of this rule.

 

 

(d)  An employer shall ensure that glazed sash and doors and other glass that might cause an injury shall be protected or removed before demolition starts.

(2) During demolition, an existing standpipe system shall remain in service as long as possible, and any sprinkler or standpipe system in a portion of a structure that is not subject to demolition shall remain in service.

  (3) If an employee is required to work in a structure that has been damaged by fire, flood, or explosion, then an employer shall ensure that the affected walls and floors are shored or braced before manual demolition starts.

(3)(4) If an area or item, such as a pipe, tank, or bin, is known or suspected to contain a hazardous substance, then an employer shall ensure that testing is performed and the hazard eliminated before demolition is permitted to begin.

(4)(5) An employer shall ensure that manual demolition of structural components starts at the top of the structure and proceeds downward so that each level is completely dropped before the next lower wall and floor is dropped, except that if a connection portion is a different level, then that portion may be removed first. This requirement does not prohibit the cutting of a floor for the removal of materials if the requirements of R 408.42044 are complied with.

(5)(6) An employer shall ensure that an employee shall not be exposed to weather conditions during demolition work if weather conditions constitute a hazard.

(6)(7) During manual demolition of a structure of skeleton steel construction, the steel framing may be left in place, but an employer shall ensure that all structural supports are cleared of loose material as the demolition proceeds downward.

(7)(8) An employer shall ensure that an employee is not permitted to work on a floor below a floor opening when demolition is conducted on the upper level, unless the employee is protected by a solid barricade not less than 42 inches high and located not less than 6 feet back from the projected edge of the opening above.

(8)(9) During demolition, an employer or his or her designated representative shall make daily inspections to detect hazards and unsafe conditions. An employer shall ensure that an employee is not permitted to work where hazards exist until the hazards are corrected by shoring, bracing, or other effective means.

 

R 408.42034  Material chutes and drops.

Rule 2034. (1) The area onto and through which material is to be dropped shall be completely enclosed with barricades not less than 42 inches high and not less than 6 feet back from the opening and the area receiving the material. Signs warning of the hazard of falling materials shall be posted on the barricades at each level containing the barricades.

(2)   Where material is dropped through more than 1 level, the opening shall be enclosed between the upper and lower levels, an enclosed chute shall be provided, or the intermediate levels shall be barricaded as prescribed in subrule (1) of this rule. If the drop is more than 40 feet inside the building, only an enclosed opening or chute shall be used. The chute or enclosure shall extend through the ceiling of the receiving level.

(3)   A material chute shall be constructed to withstand any impact load imposed on it without failure.

(4)   A material chute, or section thereof, at an angle of more than 45 degrees from the horizontal shall be entirely enclosed, except for an opening equipped with a closure at or about each floor level for insertion of materials. The opening shall not be more than 48 inches in height measured along the wall of the chute. At all stories below the top floor, the openings shall be kept closed when not in use. The chute shall fit the floor or wall opening or the open space shall be closed.

 

 

(5)   Where material is dumped from mechanical equipment or a wheelbarrow, a toeboard or bumper not less than 4 inches thick by 6 inches high nominal size secured to the floor shall be provided at each material chute opening.

  (6) Where the drop is more than 20 feet outside the exterior of the building, a chute as prescribed in subrules (3) to (5) of this rule, shall be used and shall extend to within 8 feet of the lower level.

(4)   A wall serving as a retaining wall for debris shall be capable of supporting the imposed load.

(5)   A wall serving as a bearing wall for an adjoining structure shall not be demolished until the adjoining structure has been underpinned.

  (6) The materials from a brick or masonry chimney or stack that is manually demolished shall be dropped inside the chimney or stack, unless an area around the chimney or stack that is equal in radius to 1/4 the height can be sealed off by a guardrail or barricade to prevent employee entry during the drop operation. If material is dropped inside the chimney or stack, any opening shall be closed or barricaded when material is being dropped.
