11 Capital Safety Inc–Confidential Horizontal Lifeline Systems OHSA Standards What do they really mean? OSHA states that any HLL shall be designed, installed, and used under the supervision of qualified person, as part of a complete personal fall arrest system, which maintains a safety factor of at least two or 2 to 1 safety factor. Do I have a “qualified person” on my staff? Does the 5,000 lb rule apply? Do loads have to be known every time the system is installed ?

12 Capital Safety Inc–Confidential Horizontal Lifeline Systems DIY versus Pre-Engineered Ask yourself the following three questions: Do I want to assume the liability? Do I have the testing capabilities to meet the requirements? Can I go home every night knowing I have my crews in compliance with OSHA standards?

13 Capital Safety Inc–Confidential Horizontal Lifeline Systems DIY System Problems What are the biggest problems with DIY systems: - Understanding end load of anchorages - Understanding fall clearances - “Qualified person” is either not involved or not qualified. - If not, chances are the system does not meet OSHA requirements.

14 Capital Safety Inc–Confidential Horizontal Lifeline System Most Common Mistakes? Most Common Mistakes: –Under designed end anchors

15 Capital Safety Inc–Confidential Horizontal Lifeline System Most Common Mistakes? Most Common Mistakes: –Under designed cable terminations

16 Capital Safety Inc–Confidential Horizontal Lifeline System Most Common Mistakes? Most Common Mistakes: –Pretension in the lifeline Too much tension Too little tension Constantly changing tension

17 Capital Safety Inc–Confidential Horizontal Lifeline System Most Common Mistakes? Most Common Mistakes: –No inline shock absorbers incorporated

18 Capital Safety Inc–Confidential Horizontal Lifeline System Most Common Mistakes? Most Common Mistakes: –Calculating fall clearances

19 Capital Safety Inc–Confidential Horizontal Lifeline System Most Common Mistakes? Most Common Mistakes: –User equipment

20 Capital Safety Inc–Confidential Horizontal Lifeline System HLL Loads HLL Loads, how do they work? –HLLs may depending on their geometry and angle of sag, be subjected to greater loads than the impact load imposed by an attached component. When the angle of a HLL sag is less than 30 degrees, the impact force imparted to the lifeline by an attached lanyard is greatly amplified. For example, with a sag angle of 15 degrees, the force amplification is about 2:1 and at 5 degrees sag it is about 6:1

21 Capital Safety Inc–Confidential Horizontal Lifeline System HLL Loads HLL Loads, how do they work, cont? –HLL end loads are dependent on horizontal distance or span, vertical force, and pretension in the cable.

22 Capital Safety Inc–Confidential Horizontal Lifeline System HLL Loads HLL Loads, how do they work, cont?

23 Capital Safety Inc–Confidential Horizontal Lifeline System HLL Loads HLL Loads, how do they work, cont? –For example, you are designing a two user system and you are utilizing 900 lb arresting force lanyards. Assume that your pretension yields a 10 degree vertical deflection during a maximum arresting force. The result is an end load amplification 2.9 times the arresting force or (900 lbs x 2 users x 2.9) = 5,220 lbs. Your end anchors or stanchions have to be designed for 10,440 lbs when applying the OSHA standard of 2:1.

24 Capital Safety Inc–Confidential Horizontal Lifeline System HLL Loads HLL Loads, how do they work, cont? –For example, you are designing a two user system and you are utilizing 900 lb arresting force lanyards. Assume that your pretension yields a 5 degree vertical deflection during a maximum arresting force. The result is an end load amplification 5.7 times the arresting force or (900 lbs x 2 users x 5.7) = 10,260 lbs. Your end anchors or stanchions have to be designed for 20,520 lbs applying the OSHA standard of 2:1.

25 Capital Safety Inc–Confidential Horizontal Lifeline System HLL Loads Summary Every time a HLL system is installed the following must be known: –End loads must be calculated and documented by a qualified person for end anchorage design requirements. –Pretension in the HLL must be known and maintained at the same level throughout the job, if not, the end loads could increase dramatically. –Number of users on the system has to be controlled and maintained throughout the job. –The appropriate user equipment that the personnel is using has to be controlled and known throughout the job.

26 Capital Safety Inc–Confidential Horizontal Lifeline System HLL Loads Summary How can I make figuring the end loads out easier?

27 Capital Safety Inc–Confidential Horizontal Lifeline System Inline Shock Absorbers Inline shock absorbers –Controls the end anchor forces to a pre-determined value, every time –Pretension on the system is not a huge factor when using in-line shocks. –Number of users can range up to the capacity of the in- line shock absorber. –Adds deflection of the cable which adds to your total fall distance.

28 Capital Safety Inc–Confidential Horizontal Lifeline System Fall Clearances How are they calculated: –Five main considerations: Cable deflection Braking distance of user equipment Body extension Pendulum effect Free fall

29 Capital Safety Inc–Confidential Horizontal Lifeline System Fall Clearances Factors that should be considered when using a shock absorbing lanyard.

30 Capital Safety Inc–Confidential Horizontal Lifeline System Fall Clearances Pendulum effect will add to your total fall distance.

31 Capital Safety Inc–Confidential Horizontal Lifeline System You may be saying: –“I am more confused now than before I came.” –“I need easier solutions.”

32 Capital Safety Inc–Confidential Horizontal Lifeline System Pre-Engineered HLLs The manufacturer is the qualified person for the design portion of the standard. Usually incorporate inline shock absorbers. Fall clearance charts are provided. Detailed installation instruction manual is provided. Qualified person still has to supervise the installation and use of the system.

33 Capital Safety Inc–Confidential Pilot Program – Commercial Roofer’s Kit DBI/SALA would develop a commercial roofers kit consisting of the following: 2 Roof Top anchors 1 HLL either cable or synthetic (length TBD) 2 Harnesses (type TBD) 2 User equipment (type TBD)
