Safe Work Practices

  • When hand demolition is required, it should be accomplished from a working platform.
  • Experienced personnel must install a self-supporting tubular scaffold, suspended platform, or knee-braced scaffolding around the chimney. Particular attention should be paid to the design, support, and tie-in (braces) of the scaffold.
  • A competent person should be present at all times during the erection of the scaffold.
  • It is essential that there be adequate working clearance between the chimney and the work platform.
  • Access to the top of the scaffold should be provided by means of portable walkways.
  • The platforms should be decked solid and the area from the work platform to the wall should be bridged with a minimum of two-inch thick lumber.
  • A back rail 42 inches above the platform, with a midrail covered with canvas or mesh, should be installed around the perimeter of the platform to prevent injury to workers below. Debris netting may be installed below the platform.
