Anatomy of a Fall

• It takes most people about 1/3 of a second to become aware.
• It takes another 1/3 of a second for the body to react.
• A body can fall up to 7 feet in 2/3 of a second.

Do I really need Fall Protection?
•You've carefully thought out all the angles.
•Nothing could possibly go wrong and it wouldn’t
happen to me anyway.
•You've done it a thousand times.
•You know what you're doing, its what you've been
trained to do your whole life.

Fall Protection is needed when…
OSHA Says…
• Working at 4 ft. or higher (General Industry 1920)
• Working at 6 ft. or higher (Construction 1926)
• If there is a hazard below you

Fall ClearanceLanyards
• Measure from anchor point
• Formula – LL + DD + HH + C = RD
• LL= Lanyard Length
• DD= Deceleration Distance
• HH= Height of Suspended Worker (Including Harness Stretch)
• C= Safety Factor
• RD= Required fall clearance
• Some competitors measure from working surface
• Conservative calculation
Measurement uses anchorage point as the starting point
D ring slide and harness stretch included in Height of worker
Deceleration is maximum amount per lanyard
LL+DD+HH+C=RD
6’+4’+6’+1.5’= 17.5

SRD/SRLs
SRL - Self Retracting Lanyard SRD - Self Retracting Device
Classes• Class A: A class A SRD will stop the fall within 24” and ensure the forces are below 1350 lbs.
• Class B: a class B SRD will stop the fall within 54” and ensure that the forces are below 900 lbs.
Types• SRL-R: An SRD with some sort of rescue capability, this could be an incorporated winch or
automatic descent capability.
• SRL-LE: An SRD that has been designed for a worker falling over an edge.
• Will have an integral external shock absorber.
• Will have a cable that can withstand a sharp edge.

Fall Clearance • Self Retracting Devices (SRD’s)
(Class B)
• Measured from working surface
• Most SRD’s use 6 ft. as the required fall clearance distance however new technology has allowed some SRD’s to reduce fall clearance to 4’.

Working Surfaces Rule
29 CFR 1910 General IndustryOn November 17, 2016, OSHA published its final rule on Walking and Working Surfaces.
The 513 page copy from the Federal Register can be downloaded at: https://www.federalregister.gov/documents/2016/11/18/2016-24557/walking-working-surfaces-and-personal-protective-equipment-fall-protection-systems
382017© 3M #3MScienceofSafety | 382017© 3M #3MScienceofSafety |
29 CFR 1910 General Industry WWSR
Who and what does the final rule cover?
The final rule applies to all general industry workplaces and covers all walking-working surfaces, which
include horizontal and vertical surfaces such as floors, stairs, roofs, ladders, ramps, scaffolds and elevated
walkways. The final rule also has provisions affecting fall protection systems.
The final rule covers a wide variety of general industry entities, including building management services,
utilities, warehousing, retail, window cleaning, chimney sweeping and outdoor advertising. It does not
change construction or agricultural standards.
392017© 3M #3MScienceofSafety | 392017© 3M #3MScienceofSafety |
29 CFR 1910 General Industry WWSR
Effective Date:This final rule became effective on January 17, 2017.
Some requirements in the final rule have compliance dates established after the effective date. This allows
time for employers to implement the standard.

• Fall Protection Snap Hooks, D-Rings and Carabiners. The final rule requires that D-rings, snaphooks, and carabiners be proof
tested to a minimum tensile load of 3,600 pounds without cracking,
breaking, or incurring permanent deformation. OSHA also added a new
requirement to final paragraph (c)(8) specifying that the gate strength
of snaphooks and carabiners also must be proof tested to 3,600
pounds in all directions. This direction aligns with ANSI/ASSE Z359.12
standard for Connection Components for personal fall arrest systems.

29 CFR 1910 General Industry WWSR• Training – Key Points (§1910.30).• Deadline for Training is May 17, 2017
• The final rule adds requirements that employers ensure workers who use personal fall protection and work in other
specified high hazard situations are trained, and retrained as necessary, about fall and equipment hazards, including fall
protection systems. Employers must provide information and training to each worker in a manner the worker understands.
• Trainer must be a qualified person and train workers to correctly:
• Identify and minimize fall hazards
• Use personal fall protection systems, safety nets, designated areas, dockboards, fixed, portable and mobile ladders and
rope descent systems
• Use, maintain, inspect and store equipment or systems used for fall protection
• Qualified Person Definition• Qualified describes a person who, by possession of a recognized degree, certificate, or professional standing, or who by extensive
knowledge, training, and experience has successfully demonstrated the ability to solve or resolve problems relating to the subject matter, the
work, or the project.
• Whenever there is a change in the workplace operations or equipment, or employer believes employee would benefit from
additional training based on lack of knowledge or skill, worker must be retrained.
