Use and Care Manual

2
• Fall restraint:
Worker’s center of gravity cannot fall over the unprotected edge in any direction.
A – anchor = 2 x force exerted, or 3,000 lbs.
B – body belt or full body harness = 3,000 lbs
C - Lanyard/rope = 3,000 lbs
• Personal fall arrest:
Basic system with Lanyard
A – 5,000 lbs anchorage per person. (Certified anchor may be 3,600 lbs)
B – full body harness
C – 6 ft shock-absorbing lanyard
Minimum clearance = 17.5 ft from anchor (6-ft lanyard, 3.5 ft shock
absorber, 5 ft surface to dorsal D-ring, 1 ft harness stretch, 2 ft safety factor).
System with Self-Retracting Lifeline (SRL)
A – 5,000-lb anchorage per person (Engineered anchor may be 3,000 lbs)
B – full-body harness
C – web or cable self-retracting lifeline with or without shock absorbing pack
Minimum clearance = non-shock-absorbing SRL = 5 ft; shock absorbing
(read label) = 7.5 ft; account for pendulum effect
• Work positioning:
A – 3,000 lbs anchorage per person
B – belt of full body harness
C – 5,000 lb lanyard
Minimum free-fall = 2 ft
• Rescue planning:
Prompt rescue plan in place prior to beginning work can decrease the response
time to a fall and therefore lower the danger of suspension trauma to the victim
Types of Fall Protection
• Safety monitor: (Low slope) Roong work only, roof > 50 ft requires warning line at 6 ft, monitor to edge.
• Guardrails, parapets:
42 ± 3 in. high; withstand 200 lb at top rail; guardrails must have mid-rail and toeboards if tools, material can fall to lower level
Materials: Constructed of minimum 500-lb strength material (no barrier tape). Pipe 1½ in. minimum; Wood 2 x 4 in.
minimum; two cables minimum ¼-in. diameter, top cable flagged at 6-ft intervals, no deflection under pressure below 39 in.
Mid rail (rated 150), toe board (rated 50)
• Skylights: Every skylight oor opening and hole shall be guarded by a standard skylight screen or a xed standard railing on all exposed sides.
• Warning line systems: Low slope roofs only.
General industry—“Designated Area”—minimum 6 ft from unprotected edge.
Construction—“Nonconforming Guardrail”—minimum 15 ft from unprotected edge.
System requirements—uprights withstand 16-lb force at 30-in. height; line to be rope, wire, chain of 500-lb
tensile strength, flagged at 6-ft intervals; height 34-39 in.; line attached to uprights—no line slip.
• Horizontal lifeline: Horizontal lifeline: 5000 lbs. per person attached, unless designed by qualied person with a safety factor of 2.
• Vertical lifeline: 5,000-lb anchor (only one worker per lifeline) for clearance add 1 ft for rope grab to activate, minimum clearance = 7.5 ft + lanyard length.
• Ladder climbing devices: Maximum 9-in. connector between the ladder safety device and a front (chest) D-ring, engineered support.
Must limit fall distance to 2 ft or less.
