R 408.15836 Fall protection.  
Rule 5836. (1) An employer shall ensure that a personal fall arrest or travel  
restraint system that meets the requirements in General Industry Safety and Health  
Standard Part 33 "Personal Protective Equipment," as referenced in R 408.15812, shall be  
worn and attached to the boom or basket when working from an aerial lift.  
(2) Any occupant of an aerial work platform described in R 408.15802(a) and (c)  
and Figures 1 and 3 shall use a personal fall arrest system. A personal fall arrest system  
shall only be used where the aerial lift is designed to withstand the vertical and lateral  
loads caused by an arrested fall.  
(3) An employee may use a body support with a lanyard, or other means of  
connection, and the anchorage connector and anchorage arranged so that the employee is  
not exposed to any fall distance. An employee is required to use a travel restraint system  
where the aerial lift cannot withstand the vertical and lateral loads imposed by an arrested  
fall.  
(4) An employee shall be prohibited from belting off to an adjacent pole, structure,  
or equipment while working from an aerial work platform.  
(5) An employer shall not allow employees to exit an elevated aerial work platform,  
except where elevated work areas are inaccessible or hazardous to reach. Employees may  
exit the platform with the knowledge and consent of the employer. When employees exit  
to unguarded work areas, fall protection shall be provided and used as prescribed in  
General Industry Safety and Health Standard Part 33 "Personal Protective Equipment," as  
referenced in R 408.15812.
