Duty to have fall protectionProtection required when working at 6 feet

or higher

Walking/working surfaces shall be inspected before employees begin work activities

Employees shall be allowed to work only on those surfaces which have the requisite strength to withstand their weight


Strong enough surfacesGA Tech Safety and Health Consultation Program

SCOPE AND APPLICATION

Subpart M sets forths criteria for all fall protection hazards, except: Section L - ScaffoldsSection N – Cranes and derricksSection R – Steel erection work in buildingsSection S – Tunneling operations Section V – Electric transmission and

distribution linesSection X – Stairways and ladders

Fall Protection Systems: criteria and practices...

(b) Safety net systemsShall be installed as close as practicable , but in no case

more than 30' (9. 1 m) below the working surfaceShall be subjected to impact force tests or certifiedWithout any defects Shall be inspected weekly and after any occurrence

(impact)Debris that have fallen into the net must be removed

before starting workMaximum size of each mesh opening shall not be longer

than 6” and each opening will not exceed 36” square All border rope must have a minimum breaking strength

of 5000 pounds



(c) Personal fall arrest systems

Effective January 1, 1998, body belts are authorized to be used only for positioningDee-rings and snaphooks shall have a minimum

tensile strength of 5,000 poundsSnaphooks shall be of the locking typesHorizontal lifelines shall be installed by a

qualified person and maintain a safety factor of at least 2


Body belts only for positioning

Chain for positioning

Fall protection



(c) Cont..

Lanyards and vertical lifelines shall have a minimum breaking strength of 5,000 pounds

A body harness shall withstand a force of 1,800 pounds

Be mindful of the correct attachment point to the wearer’s body, plans for prompt rescue of the employee, and inspections of equipment prior to use



(d) Positioning device systemsEmployee can not free fall more than 2' (0.61 m) Shall be inspected prior to each useBody belts and harnesses shall be used only for

employee protection

(e) Warning linesShall be erected around all sides of the roof

work area



(e) Cont.

Access points shall be blocked when there is no work Warning lines shall be flagged with high-visibility

materials The lowest point of the warning line is not less than

34" (0.9 m) and the highest point at not more than 39" (1 m)



(f) Controlled access zonesUsed in areas where leading edges change

constantlyIn areas with overhand bricklaying work at edgesWhen erecting precast concrete membersAccess permitted only to trained and qualified

employeesWritten information (signs) at points of access


Leading edges GA Tech Safety and Health Consultation Program


Competent person as monitor

At same visual level of that of employees

Close enough to communicate orally

Mechanical equipment shall not be stored in the monitoring area

Only employees engaged in roofing work allowed

Employees shall follow the monitor’s instructions

Monitor shall not have other responsibilities or functions
