Fall Protection


The payload project shall observe and use applicable industry standards for fall protection (such as guard rails, lanyard anchorages, lanyards, snap hooks, ladders, inspections). Specific criteria for the equipment listed above can be found in ANSI Z359.1, Personnel Fall Arrest Systems, Subsystems, and Components; ANSI A10.14, Construction and Demolition Operations - Requirements for Safety Belts, Harnesses, Lanyards and Lifelines for Construction and Demolition Use; NPR 8715.1, NASA Occupational Safety and Health Programs, 29 CFR 1910.23, Guarding Floor and Wall Openings and Holes; 29 CFR 1910.27, Fixed Ladders; and 29 CFR 1926.105, Safety Nets.

C







Fall Hazards: All open-sided floors or fall hazards over 4 feet or any height where falls into hazards such as moving machinery, impaling, or drowning hazards exist should be guarded by standard guard rails with mid-rails and toe boards.

Fall protective PPE should be used when installing guardrails, safety nets, and other fall protection.

Hazard Guards: If standard guard rails are not installed, PPE, in the order of preference listed below, should be used to protect personnel if they are within 6 feet of the hazard:

  1. Full body harness (ANSI Class III).

  2. Chest harness (ANSI Class II).

  3. Safety nets (29 CFR 1926.105).

PPE Lanyards: PPE should be attached to anchorages by a lanyard that limits the length of a fall to no more than 6 feet. The order of preference is as follows:

  1. Self-retracting lanyard (inertia reel).

  2. Shock absorbing lanyard.

  3. Nylon rope lanyard.

  4. Wire rope lanyard (for welders).

Lanyard Anchorages:

  1. Handrails should not be used for anchorages or lanyard tie-off points.

  2. Life line (dog-run) style anchorages for lanyards require appropriate justification with analysis to be submitted and specific approval by the PSWG, Range Safety or local safety authority for each application. Dog-runs are not an acceptable alternative to installed platforms or walkways.

Installation of Permanent Anchorage Connectors:

  1. Visual inspection of installed permanently fixed anchorage connections and dog-runs should be accomplished annually by the payload project. Documentation should be available for review by the PSWG and Range Safety.

  2. Suspect connections or anchorages should receive NDE as determined by the PSWG, Range Safety or local safety authority and should be repaired or replaced as required.

Fall Protection Snap Hooks. Fall protection snap hooks used in fall protection systems should be sized to ensure proper connection.

Fall Protection Equipment Inspections:

  1. Each article of PPE should be visually inspected by the user before use.

  2. All PPE should be thoroughly inspected at least twice a year by a qualified person of the organization that owns the PPE.

Inspection Tags: Each piece of PPE should have a visible tag or other indication of inspection permanently attached with the following information:

  1. The date inspected.

  2. The next inspection due date.

  3. The stamp or signature of the quality inspector.

Ladder Fall Protection:

  1. Ladder fall protection should be installed on all fixed ladders with a fall hazard of 20 feet or more.

  2. Ladder safety devices with body belts should be the preferred method of fall protection.
