Personal Fall Protection System
A Personal Fall Protection (PFP) system prevents a worker from falling or—if the worker is falling—stops the fall. PFP systems include guard rails, safety nets, personal fall restraint systems, personal fall arrest systems, and positioning device systems.
-Guardrails are required to guard the open sides of all work surfaces that are 7 1/2 feet or higher or workers must be protected by other means. The railing must be made from select lumber (Doug Fir#1 or better 1500 Psi or equivalent) and must consist of a top rail 42 inches to 45 inches high, 2" x 4" (min.); a 1" x 6" mid-rail halfway between the top rail and the floor, and support posts at least 2" x 4" at 8 feet on center
-A Personal Fall Restraint (PFR) system is used to prevent an employee from falling. It consists of anchorages, connectors, and a body belt or harness. It may include lanyards, lifelines, and rope grabs designed for that purpose
-A Personal Fall Arrest (PFA) system is used to stop an employee during a fall from a working level and to keep him or her from hitting a lower level or structure. The system consists of an anchorage, connectors, and a body harness. It may include a lanyard, a lifeline, a deceleration device, or suitable combinations of these. A PFA system must meet the following requirements:
a. It must limit the maximum arresting force on an employee to 1,800 lbs.
b. It must be rigged such that an employee can neither free fall more than 6 feet nor contact any lower level, and, where practicable, the anchor end of the lanyard shall be secured at a level not lower than the employee’s waist.
c. Anchorage points must be able to support 5,000 lbs. per employee attached or:
Must be designed, installed, and used as part of a complete PFA system with a safety factor of two; and
Under the supervision of a qualified person.
d. The PFA system lifeline must meet the following requirements:
It must be able to support 5,000 lbs.
Each employee must be attached to a separate lifeline.
Exception: During the construction of elevator shafts, two employees may be attached to a lifeline that is able to support 10,000 lbs.
The lower end of the vertical lifeline must extend to within 4 feet from the ground.
A horizontal lifeline system must be designed, installed, and used under the supervision of a qualified person and maintained with a safety factor of at least two.
Note: the use of a body belt as a part of a PFA system is prohibited.
-Body belts, harnesses, and components shall be used only for employee protection and not to hoist materials. Body belts used in conjunction with fall restraint systems or positioning devices shall limit the maximum arresting force on an employee to 900 lbs
-Safety nets may be used in place of all other fall protection systems if the nets are installed properly
