Revised: October 2023
Planks spanning the distance between adequate beams shall be used where
necessary as a substitute for weakened floors, and as access walkways over
open or weakened areas.
When demolishing floors and roofs, employees shall be prohibited from
working below this activity. Demolition of floor spaces shall continue until all
unsupported flooring is removed. When employees are required to remove
floor support beams, wall sections, etc., by hand, code-compliant scaffolding
shall be provided and used where necessary to insure employee safety.
Stairways designated as means of access shall be maintained clear for use
within two floors or twenty-four feet of the demolition work above.
Ladders shall be provided for these remaining two floors and shall be
constructed and maintained to meet code compliance. All non-compliant
accessways shall always be closed off.
Walkways or ladders shall be provided to enable employees to safely reach or
leave any scaffold or wall.
In a multi-story building, when a stairwell is being used for access or egress, it
shall be properly illuminated by either natural or artificial means, and
completely and substantially covered over at a point not less than two floors
below the floor on which work is being performed, and access to the floor
where the work is in progress shall be through a properly lighted, protected,
and separate passageway.
Construction passenger elevators for hoisting employees shall be provided on
demolition projects on multi-story buildings seven or more floors or seventytwo feet or more in height.
o Landings shall be provided for the passenger elevators on or in
buildings at intervals not to exceed four floors or forty-eight feet.
o Where there is doubt concerning structural integrity or engineering
data indicates attachment of an elevator may jeopardize the strength
of the building or structure, alternate methods of installation can be
considered.
If the method of demolition leaves the structural steel frame in place, then the
tier of beams next below the tier from which beams and columns are being
removed shall be planked over, unless safety nets are used, or the floor of such
tier has not been removed. Necessary openings for material handling are
allowed. All loose material shall be removed from the steel frame as
demolition progresses downward.
o Provisions for dust control shall include the use of water to keep
material or debris sufficiently wet or other equivalent steps taken to
prevent dust from rising.
Mechanical equipment shall not be used on floors or working surfaces unless a
qualified person has determined that such floors or surfaces are of sufficient
strength to support the imposed load.
