  1. A New Era for an Old StandardA Review of Changes to ANSI Z359.1

  2. National standard for fall arrest equipment Originally published in 1992 and revised in 1999 Covers requirements for fall arrest equipment including harnesses, lifelines, lanyards, energy absorbers and anchorage connectors Standard is divided into 8 sections Scope, Purpose, Application, Exceptions and Interpretations Definitions Requirements Testing Marking and Instructions User Inspection, Maintenance and Storage of Equipment Equipment, Selection, Rigging, Use and Training References What is ANSI Z359.1?

  3. Expansion of standard to become ‘family of standards’ Effective date of November 24, 2007 Sections include: Z359.0 Definitions and Terminology Used for Fall Protection and Fall Arrest Z359.1 Safety Requirements for Personal Fall Arrest Systems, Subsystems and Components Z359.2 Minimum Requirements for a Comprehensive Managed Fall Protection Program Z359.3 Safety Requirements for Positioning and Travel Restraint Systems Z359.4 Safety Requirements for Assisted-Rescue and Self-Rescue Systems, Subsystems and Components Changes to ANSI Z359.1

  4. Standard remains the same as the current standard with several important revisions and additions Gate hook strength of snaphooks and carabiners has changed Gate face must withstand load of 3,600 pounds (up from 220 pounds) Side of the gate must withstand load of 3,600 pounds (up from 350 pounds) Minor axis of a snaphook or carabiner, except those with captive eyes, must withstand 3,600 pounds (new to standard) Tensile load for the snaphook or carabiner must withstand 5,000 pounds (same as old version) ANSI Z359.1 Safety Requirements for Personal Fall Arrest Systems, Subsystems and Components

  5. ANSI Z359.1(Continued)

  6. Snaphooks and carabiners must be marked with: Year of manufacture Manufacturer’s identification Supplier part number Load rating for the major axis of the connector stamped or otherwise permanently marked on the device Load rating for gate stamped or otherwise permanently marked on the gate mechanism Markings for connectors shall be sufficient to provide traceability For connectors that are non-integral, include the standard number, “Z359.1(07)” ANSI Z359.1(Continued)

  7. Front-mounted D-ring element on harnesses can now be used for fall arrest Maximum free-fall distance must be limited to two feet and maximum arrest force to 900 pounds The old standard only allowed the frontal D-ring to be used for ladder climbing, fall restraint and work positioning ANSI Z359.1(Continued)

  8. Twin-leg lanyards now addressed in standard Must have a minimum of 5,000 pounds breaking strength Must be marked with several warnings: Connect only the center snaphook to the fall arrest attachment element Do not attach the leg of the lanyard that is not in use to the harness except to attachment points specifically designated by the manufacturer for this purpose Do not rig the lanyard to create more than a six foot free-fall Do not allow the legs of the lanyard to pass under arms, between legs or around the neck ANSI Z359.1(Continued)

  9. Anchorage load has changed from “3,600 pounds when certification exists” to “two times the maximum arrest force permitted on the system when certification exists” Additions to the Equipment Rigging and Use section include requirements that harnesses and fall arrest systems be selected and properly sized for the user and connectors, snaphooks and carabiners must be compatible with the equipment they are used with Lanyards, lifelines and anchors- no knots and kept clear of workplace and environmental hazards Additions to the Training section include provisions that training address how to select, inspect and use fall protection equipment; training methods and language; and assessments of trainers Editorial revisions: The term “user” has been clarified with the terms “competent person,” ”qualified person” and “authorized person” ANSI Z359.1(Continued)

  10. Guidelines to organize and manage a fall protection program Identify, evaluate and eliminate (or control) fall hazards through planning Ensure proper training of personnel exposed to fall hazards Ensure proper installation and use of fall protection and rescue systems Implement safe fall protection and rescue procedures Program required whenever one or more persons are routinely exposed to fall hazards ANSI Z359.2 Minimum Requirements for a Comprehensive Managed Fall Protection Program

  11. Duties and responsibilities are laid out for each person associated with the comprehensive fall protection program Employer-Commitment, provide procedures, equipment and training Program Administrator-developing program, guidance & maintenence Qualified Person - design/installation of equipment Competent Person- program supervisor, hazard surveys, potential hazards, inspections, training and ability to stop work at hazardous site Authorized Person- user of equipment, proper inspection Competent Rescuer- procedures and training Authorized Rescuer- user of rescue equipment and training Qualified Person Trainer Competent Person Trainer Competent Rescuer Trainer ANSI Z359.2(Continued)

  12. Fall protection procedures should be developed based on results of fall hazard survey report Survey of work environment by Qualified or Competent Person Report prepared for each fall hazard Identifies methods to eliminate or control the hazard Minimum requirements for fall protection procedures Written by Program Administrator Provide for 100% continuous fall protection Include training and qualifications of authorized persons permitted to use system Anchor identification and criteria Equipment assembly, usage and inspection Provisions for post-fall rescue Requirements for investigation of incidents ANSI Z359.2(Continued)

  13. Preferred hierarchy for fall protection Elimination or Substitution (removal of fall hazard) Passive Fall Protection (isolation of hazard from workers) Fall Restraint (prevents worker from reaching a fall hazard) Fall Arrest (safely stops a fall after it has begun) Administrative Controls (work practices or procedures that warn a worker before approaching a fall hazard) General Requirements for Fall Protection Systems Certified components and anchors Certification must be in writing and must state that the parts meet the requirements of Z359 based on testing or the application of proven analytical methods carried out by a qualified person or entity Design of system based on testing or engineering calculations Design and installation must be performed under supervision of a Qualified Person Maximum arrest force 1,800 pounds or less Fall restraint limited to working surfaces at, or less than, a 4:12 slope ANSI Z359.2(Continued)

  14. Facilities under construction must consider fall hazards in the design stage The preferred order of controlling fall hazards must follow the hierarchy If a fall hazard cannot be eliminated, the facility must provide anchorage locations for fall protection equipment Training requirements are addressed in-depth References and requires compliance with ANSI Z490.1, Criteria for Accepted Practices in Safety, Health and Environmental Training Specific requirements for each person defined in the managed fall protection program Regularly scheduled re-training Documented performance through observation, measurement and recording of results ANSI Z359.2(Continued)

  15. Anchorage systems Fall arrest anchorages must withstand a static load of 5,000 pounds for non-certified anchorages or two-times the maximum arresting force for certified anchorages For work positioning systems, anchorages must withstand a static load of 3,000 pounds for non-certified anchorages or two-times the foreseeable force for certified anchorages For travel restraint systems, anchorages must withstand a static load of 1,000 pounds for non-certified anchorages or two-times the foreseeable force for certified anchorages For horizontal lifeline systems, anchorages must withstand at least two-times the maximum tension developed in the lifeline during fall arrest in the direction applied by the lifeline forces Anchorages for rescue systems must withstand a static load of 3,000 pounds for non-certified anchorages or five-times the applied load for certified anchorages ANSI Z359.2(Continued)

  16. Inspections Daily inspections of fall protection equipment and anchorages by the authorized person, or user of the equipment, as well as yearly inspection by a qualified person, competent person or competent rescuer are required Items to verify include: Presence and legibility of markings and tags Presence of all integral components of the equipment (ex/hardware and webbing) Absence of defects and damage ANSI Z359.2(Continued)

  17. Rescue procedures If emergency services are not able to answer a request for assistance in a timely manner or if they do not have adequate equipment, then companies should have in-house rescue procedures and trained personnel in place Program effectiveness should be evaluated at regular intervals of no more than two years If an accident occurs, the incident must be thoroughly investigated and documented promptly ANSI Z359.2(Continued)

  18. Addresses safety requirements for rescue systems Requirements for performance, design, marking, qualification, instruction, training, use, maintenance and removal from service Equipment includes connectors, winches/hoists, descent control devices, rope tackle blocks, and self-retracting lanyards with integral rescue capability Utilized in pre-planned self-rescue and assisted- rescue applications for 1-2 persons Rescuer must assess workplace conditions prior to selecting a rescue system Must be based on compatibility with other fall protection equipment as well as hazards and anchorages that are present ANSI Z359.4 Safety Requirements for Assisted-Rescue and Self-Rescue Systems, Subsystems and Components

  19. Provides guidance in creating fall protection programs Clear lines of authority and responsibility Detailed job planning and expanded training Broadens scope of standard, additional work tasks and equipment types Work positioning and travel restraint Rescue and rope access Improves strength and performance of fall protection equipment Increased snaphook & carabiner gate strength Additional testing for twin leg lanyards Establishes requirements for positioning, restraint and rescue equipment May increase compliance and reduce number of accidents Protects worker from potential mis-use reducing risk and liability Hook changes reduce the chance of forced “roll-out” for added safety Values of Expanded Fall Protection Standard

  20. The outlook is that the Z359 family of standards will drive higher rates of compliance because the added details provide a better understanding of how to select and use equipment to keep workers safe in all types of work environments. Increasing compliance by as little as one percentage point will protect thousands of workers and could potentially save hundreds of lives. Values of Expanded Fall Protection Standard

  21. What has Changed Z359 Fall Protection Code Version 2.0 Effective November 16, 2009 updates include: ANSI/ASSE Z359.13-2009“Personal Energy Absorbers and Energy Absorbing Lanyards”Establishes requirements for the performance, design, marking, qualification, instructions, inspection, maintenance and removal from service of energy absorbing lanyards and personal energy absorbers. ANSI/ASSE Z359.12-2009“Connecting Components for Personal Fall Arrest Systems”Establishes requirements for the performance, design, marking, qualification, test methods and removal from service of connectors. ANSI/ASSE Z359.6-2009“Safety Requirements for Personal Fall Arrest Systems (PFAS)”Intended for engineers with expertise in designing fall-protection systems. It specifies requirements for the design and performance of complete active fall-protection systems, including travel-restraint and vertical and horizontal fall-arrest systems. .

  22.
