CONSTRUCTION AND DEMOLITION OPERATIONS
1. GENERAL
1.1 Scope. This standard establishes performance criteria for personal fall protection equipment and systems in construction and demolition and provides guidelines, recommendations for their use and inspection. It includes, but is not limited to; fall arrest, restraint, positioning, climbing, descending, rescue, escape and training activities.
Exceptions: This standard does not include lineman’s body belts, pole straps, window washer’s belts, chest/waist harnesses and sports equipment.
1.2 Purpose. The purpose of this standard is to provide minimum guidelines to users of personal fall protection equipment.
1.3 Application. This standard applies to users of personal fall protection equipment; to those personnel responsible for the selection, procurement, inspection, use, care and maintenance of the equipment; and to those responsible for training and supervision of the users.
1.4 Resolutions. In order to provide for superior protection to the user, this standard permits:
1.4.1 Only full body harnesses shall be used for fall arrest. The fall arrest attachment point of the body harness shall be at the center of the user’s back near shoulder level.
1.4.2 Maximum arresting force imposed on the user’s body shall not exceed 1, pounds (8kN).
1.4.3 All equipment used in a fall protection system shall be compatible to limit force levels, maintain system strength and prevent accidental disengagement.
1.4.4 Equipment serviced by the manufacturer or their authorized representative shall be capable of meeting all performance requirements of this standard.
1.5 Exceptions. In cases of practical difficulty or undue hardship, the responsible authority may grant exceptions to the literal requirements of this standard or permit the use of other devices or methods, but only when it is clearly evident that personnel and equipment protection is assured.
2. DEFINITIONS
2.1 Accidental Disengagement. A process whereby a connector uninten- tionally comes free from the component to which it is attached.
2.2 Activation Distance. The dis- tance traveled by a fall arrester or the amount of line payed out by a self-retracting lanyard (SRL) from the point of onset of a fall to the point where the fall arrester or self-retracting lifeline begins to apply a braking or stopping force.
2.3 Active Fall Protection. A fall protection system that requires authorized persons to wear or use fall protection equipment and that requires fall protection training.
2.4 Anchorage. The terminating com- ponent of a fall protection system or rescue system that is intended to support any forces applied to the system.
AMERICAN NATIONAL STANDARD A10.32-
12
2.18 Connector. A component or element that is used to couple parts of the system together. A connector may be an independent component (such as a carabiner) of a system or it may be an integral element of a component, hybrid component, subsystem or system (such as a buckle or D-Ring sewn into a body support or a snaphook spliced or sewn into a lanyard or self-retracting lanyard). Connectors are sometimes referred to as hardware.
2.19 Deceleration Device. Any mech- anism which serves to dissipate energy during a fall.
2.20 Deceleration Distance. The vertical distance between the user's fall arrest attachment at the onset of fall arrest forces during a fall, and after the fall arrest attachment comes to a complete stop.
2.21 Descent Control Device. An automatic or manually controlled lowering device for escape or rescue. May be used as part of a single point suspended scaffold in conjunction with an independent lifeline fall arrest system.
2.22 Energy (Shock) Absorber. A component whose primary function is to dissipate energy and limit deceleration forces which the system imposes on the body during fall arrest.
2.22.1 Energy Absorber, Horizontal Lifeline. An energy absorber that is attached to one of the end anchorages or anchorage connectors of a horizontal lifeline subsystem.
2.22.2 Energy Absorber, Personal. An energy absorber that is attached to a harness.

2.23 Fall Arrest. The action or event of stopping a free fall or the instant where the downward free fall has been stopped.
2.24 Fall Protection. Any equipment, device or system that prevents an accidental fall from elevation or that mitigates the effect of such a fall. Fall protection includes eliminating or controlling hazards, passive fall protection, fall restraint, fall arrest and administrative controls.
2.25 Force Factor. The ratio of the peak arresting force recorded using a rigid weight in laboratory testing to that on a human body having the same weight, both falling under identical conditions. For the purposes of this standard, a registered peak force shall be divided by 1.1 to allow for body compression.
2.26 Free Fall. The act of falling before a fall protection system begins to apply forces to arrest the fall.
2.27 Free-Fall Distance. The vertical distance traveled during a fall, measured from the onset of a fall from a walking working surface to the point at which the fall protection system begins to arrest the fall. This distance excludes deceleration distance and the elongation of a lifeline or lanyard, but includes any distance that a deceleration device slides before engaging or the distance that a self-retracting lifeline or lanyard extends before fall arrest forces are applied.
2.28 Hardware. A rigid component or element that is used to couple parts of the system together.
2.29 Inspection. An examination of equipment or systems to assess conformance to a particular standard.
