Mich. Admin. Code R. 408.41213 - Guardrails; fall arrest devices
Rule 1213.
(1) A
guardrail shall be installed on any open side or end of a scaffold work
platform that is 10 feet (3.1 meters) or more above the floor or ground, except
for any of the following:
(a) A boatswain's
chair.
(b) A catenary
scaffold.
(c) A float
scaffold.
(d) A ladder jack
scaffold.
(e) A needle beam
scaffold.
The guardrail shall be as prescribed in Construction Safety Standard Part 21. "Guarding of Walking and Working Areas," as referenced in R 408.41201.
(2) An employee on a boatswains chair,
catenary scaffold, float scaffold, needle beam scaffold, or ladder jack
scaffold shall be protected by a personal fall arrest system. An employee on a
single-point or 2-point adjustable suspension scaffold shall be protected by
both a personal fall arrest system and guardrail system.
(3) A personal fall arrest device as
prescribed in Construction Safety Standard Part 45. "Fall Protection," as
referenced in
R
408.41201, shall be worn and attached to a substantial
portion of a scaffold when the work platform of an adjustable suspension
scaffold with overhead protection is 10 feet (3.1 meters) or more above the
floor, water, or ground. Separate safety lines shall be attached to a
substantial portion of the structure above and to the scaffold by an approved
fall prevention device to prevent the scaffold from falling more than 12 inches
if the scaffold suspension system fails.
(4) A top rail or an intermediate rail may be
eliminated if the configuration of the scaffold and the material deck provides
equivalent protection to prevent an employee falling from the platform or if a
personal fall arrest device is worn.
(5) A cross brace may be used as part of the
guardrail system as follows:
(a) If the pivot
point occurs from 36 inches to 48 inches above the platform, then a midrail
shall be added midway between the platform and the brace pivot point.
(b) If the pivot point occurs from 18 inches
above the platform, then a top rail shall be added.
(c) If the pivot point occurs less than 18
inches or more than 48 inches above the platform, then both a top rail and
midrail shall be provided.
(6) An employer shall have a competent person
determine the feasibility and safety of providing fall protection for employees
erecting or dismantling supported scaffolds. An employer shall provide fall
protection for employees erecting or dismantling supported scaffolds where the
installation and use of the protection is feasible and does not create a
greater hazard.
(7) If vertical
lifelines are used, then they shall be fastened to a fixed safe point of
anchorage and shall be protected from sharp edges and abrasion. Safe points of
anchorage include structural members of buildings, but do not include any of
the following:
(a) Standpipes.
(b) Vents.
(c) Other piping systems.
(d) Electrical conduit.
(e) Outrigger beams.
(f) Counterweights.
(8) If horizontal lifelines are used, they
shall be secured to 2 or more structural members of the scaffold or may be
looped around both suspension and independent support lines equal in number to
the number of points supported and equivalent in strength to the strength of
the suspension ropes. Independent support lines and suspension ropes shall not
be attached to the same points of anchorage
