PART 28 Personnel Hoisting In Steel Erection  
R 408.42801 Scope.  
Rule 2801. (1) This part sets forth requirements to protect employees from the  
hazards associated with steel erection activities involved in the construction,  
alteration, or repair of single and multistory buildings, bridges, and other structures  
where steel erection occurs.

R 408.42804 Definitions  
Rule 2804. (1) "Competent person" means a person who is experienced and  
capable of identifying an existing or potential hazard in surroundings, or under working  
conditions, that are hazardous or dangerous to an employee and who has the authority  
and knowledge to take prompt corrective measures to eliminate the hazards.  
(2) "Connector" means an employee who, working with hoisting equipment, is  
placing and connecting structural members or components.  
(3) "Controlled load lowering" means lowering a load by means of a mechanical  
hoist drum device that allows a hoisted load to be lowered with maximum control  
using the gear train or hydraulic components of the hoist mechanism. Controlled load  
lowering requires the use of the hoist drive motor, rather than the load hoist brake, to  
lower the load.  
(4) "Headache ball" means a solid iron weight, usually spherical, used to keep the  
loadline taut and positioned above the hook.  
(5) "Load line standing platform" means an attachment to the headache ball of a  
crane that provides adequate footing for the safe transport of connectors.  
(6) "Personal fall arrest system" means a system used to arrest an employee in a  
fall from a working level. A personal fall arrest system consists of an anchorage,  
connectors, a body harness, and may include  
lanyard, deceleration device,  
lifeline, or suitable combination of these. The use of a body belt for fall arrest is  
Page 1  
(7) "Positioning device system" means a body belt or body harness rigged to allow  
an employee to be supported on an elevated, vertical surface, such as a wall or column,  
and work with both hands free while leaning.  
(8) "Purlin, in systems-engineered metal buildings," means a "Z" or "C" shaped  
member formed from sheet steel spanning between primary framing and supporting  
roof material.  
(9) "Steel erection" means the construction, alteration, or repair of steel buildings,  
bridges, and other structures, including the installation of metal decking and all planking  
used during the process of erection.

R 408.42806 Reference of standards.  
Rule 2806. (1) The following occupational safety and health administrative  
standards are referenced in this standard.Up to 5 copies of these standards may be  
obtained at no charge from the Michigan Department of Labor and Economic  
Growth, MIOSHA Standards Section, 7150 Harris Drive, P.O. Box 30643, Lansing,  
Michigan 48909-8143, or via the internet at:  
time of adoption of these rules, is 4 cents per page.  
(a) Construction Safety Standard Part 26. "Steel Erection" being R 408.42601 to R  
408.42655 of the Michigan administrative code.  
(b) Construction Safety Standard Part 45. "Fall Protection," being R 408.44501  
to R 408.44502 of the Michigan administrative code.  
History: 2007 AACS.  
R 408.42809 Personnel hoisting.  
Rule 2809. (1) All the provisions of construction safety standard Part 26. "Steel  
Erection" being R 408.42601 to R 408.42655, which is referenced in R 408.42806,  
apply to all hoisting.  
(2) Riding the headache ball is prohibited except when the work area is  
inaccessible or hazardous to reach by other means, a maximum of 2 connectors may ride  
the headache ball to and from the workstation with the knowledge and consent of the  
employer or the employer's designated representative. The connector or connectors  
may be lifted to the workstation only when all of the following conditions exist:  
(a) Connectors riding a load line standing platform shall be protected from falling  
by a positioning device system or a personal fall arrest system as prescribed in  
construction safety standard Part 45. "Fall Protection," R 408.44501 to R 408.44502  
which is referenced in R 408.42806.  
(b) The connector or connectors and his or her immediate supervisor, who shall  
be a competent person, and the operator who will perform the lift shall verbally agree and  
certify in writing that using the load line standing platform is the safest alternative.  
They shall plan the lift together to minimize the transport distance. A minimum  
Page 2  
distance of 20 feet shall be maintained between the load line standing platform and the  
top sheave.  
(c) A load line standing platform shall be a minimum of 3/8 of an inch thick steel  
plate not less than 12 inches nor more than 18 inches in diameter and shall provide  
means for slip resistant footing. The platform shall be secured in such a manner to  
prevent tipping and shall be placed between the headache ball and the wedge socket.(See  
figure 1.) As an alternative, a shackle rated not less than 25 tons may be used.(See figure  
Page 3  
(d) No rigging or load shall be attached to the crane or derrick during the use of a  
load line standing platform by the connector or connectors.  
(e) The maximum rate of travel for the connector or connectors riding the load  
line standing platform shall be 100 feet per minute. Free-spooling and live booms are  
prohibited. Controlled load lowering shall be used when the load line standing  
platform is used to lower the connector or connectors.  
Page 4  
(f) There shall be a communication system between the connector or connectors on a  
load line standing platform and the operator of the crane or derrick. The system may be  
hand signals or a closed 2-way selective frequency radio system. Hand signals shall  
be followed according to appendix A of this part.  
(g) An operator of a crane or derrick shall:  
(i) Not be authorized to raise or lower the connector or connectors on a load line  
standing platform unless the operator is certified by the national commission for the  
certification of crane operators or an equivalent crane certification organization.  
(ii) Be trained in all of the provisions of R 408.42809(2) before being allowed to  
transport the connector or connectors on a load line standing platform.  
(h) When a load line standing platform is in use by the connector or  
connectors, the operator of a crane or derrick shall maintain the minimum distance  
from an energized power transmission or distribution line as required in table 1, as  
Up to 50 kV  
Over 50 kV  
20 feet  
20 feet + 0.8 inch per kV over 50 kV  
(i) The load line of a crane or derrick that is used to raise or lower the connector or  
connectors on a load line standing platform shall have a safety factor of 10 for the  
anticipated load, and be equipped with a swivel to prevent any rotation of the load  
line standing platform. A minimum of 1/2-inch diameter load line shall be used.  
(j) Neither the load line standing platform nor the boom shall be lowered below  
the point where less than 3 full wraps of the wire rope remain on their respective drums.  
(k) A crane or derrick that is used to raise or lower a load line standing platform  
shall be set level according to the crane or derrick manufacturer's specifications. The  
travel lock shall be engaged on a crane when the load line standing platform is in use.  
(l) A crane that is equipped with outriggers shall have the beams and jacks fully  
extended to provide maximum stability and the floats shall have a stable bearing  
when the load line standing platform is in use by the connector or connectors. A  
crawler crane shall have its crawlers fully extended when the load line standing  
platform is in use.  
(m) Where a crane or derrick will be used to elevate the connector or  
connectors on the load line standing platform to an area where there has been no previous  
lift of structural members, a trial lift shall be performed and consist of positioning the  
load line standing platform to the position it is to be used with an assumed minimum  
anticipated load of 1,000 pounds. The operator shall determine that all configurations  
necessary to reach the work location will allow the crane or derrick to remain under the  
50% limit of the hoisting capacity; that all systems, controls, and safety devices are  
activated and functioning properly; and that interferences do not exist. This will be done  
at each set-up location of a crane or derrick prior to elevating the connector or
