  1. FALL PROTECTION Bureau of Workers’ Comp PA Training for Health & Safety (PATHS) OSHA 29 CFR 1926 Subpart M (1926.500-503) OSHA 29 CFR 1910 Subparts D, F, I (1910.23, 66, 67, 132) PPT-012-02

  2. Importance of Fall Protection • Each year, approximately 14 percent of fatal workplace injuries are caused by falls (Source: U.S. Dept. of Labor). • In construction, approximately 150-200 workers are killed annually due to falls (Source: OSHA). PPT-012-02

  3. Fall Protection Requirements General Industry (OSHA 1910) – must have in place if working at or above four (4) feet Maritime (OSHA 1915) – must have in place if working at or above five (5) feet Construction (OSHA 1926) – must have in place if working at or above six (6) feet PPT-012-02

  4. Determination • Employer should determine if walking/working surfaces have structural strength and integrity to support employees safely. • Employer should verify employees are allowed to work only on surfaces having strength and integrity. Is this safe? Definitely not! PPT-012-02

  5. Competent Person One who is capable of identifying existing and predictable hazards in the surroundings or working conditions, which are unsanitary, hazardous or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them. PPT-012-02

  6. Qualified Person One who, by possession of a recognized degree, certificate or professional standing, or who by extensive knowledge, training and experience, has successfully demonstrated ability to solve or resolve problems relating to the subject matter, the work or the project. PPT-012-02

  7. Factors Affecting Total Fall Distance • Length of connecting means (i.e., lanyard length, use of carabineers, snap hooks, etc.) • Position and height of anchorage relative to work platform/area (always keep above head whenever possible) • Position of attachment and “D-ring” slide on full body harness • Deployment of shock absorber (max. 42”) • Movement in lifeline • Initial position of worker before free fall occurs PPT-012-02

  8. Types of Fall Protection Systems • Articulating manlifts provided with restraint systems and full body harness to anchor point below waist • Guardrails with toeboards • Personal fall arrest systems: Anchor points (rated at 5,000 lbs.) Connectors (self-locking snap hooks) Retractable lanyard Full body harness Restraint line-lanyard Shock absorbing lanyard Rope grabs PPT-012-02

  9. Types of Fall Protection Systems • Engineered life lines • Warning lines • Safety nets • Safety monitor systems PPT-012-02

  10. Recommended Locations for Fall Protection • All flat and low sloped roof locations when within 6’ of roof edge or for repair/maintenance • All exterior and interior platforms, catwalks, towers/antennas, etc. • All exterior and interior ladders above 20 feet • All mezzanine and balcony edges PPT-012-02

  11. Recommended Locations for Fall Protection • All open excavations/pits • All tasks requiring use of manlifts • Scaffolding erection 10’ in height or greater • Tuck-pointing/chimney repair • Gymnasium (catwalks) PPT-012-02

  12. Personal Fall Arrest Systems • Full body harness used • Should be inspected before each use by employee, looking for: ▪ Deteriorated areas ▪ Excessive wear ▪ Bent hooks/rings ▪ Evidence of impact/damage PPT-012-02

  13. Personal Fall Arrest Systems • Connectors should be inspected to ensure they are drop-forged, pressed, formed steel or equivalent material. • Connectors should have corrosion-resistant finish, and surfaces/edges should be smooth. • D-rings and snap hooks should have minimum tensile strength of 5,000 lbs. and should be proof tested to 3,600 lbs. • Only shock absorbing or retractable lanyards should be used (keeps impact forces to the body at a minimum). PPT-012-02

  14. Personal Fall Arrest Systems • Nylon rope or nylon straps with locking snap hooks used for restraints. • Ensure unintentional disengagement of snap hooks cannot happen by either: • Checking to see if snap hooks are correct size for place they are to be connected, or • Snap hooks are of the locking type. PPT-012-02

  15. Personal Fall Arrest Systems • Snap hooks should not be engaged as follows: ▫ Directly to webbing, rope, wire rope ▫ To each other ▫ To D-ring that has another snap hook attached ▫ To a horizontal lifeline • Maximum free-fall distance not to exceed 6 feet. • Consideration should be given to total fall distance. PPT-012-02

  16. Calculating Total Fall Distance • Total length of shock absorbing lanyard • Height of person • Location distance of D-ring from work surface or platform • Always allow minimum of 6 feet clearance above ground, equipment, etc., at end of fall from fall-arrest point! PPT-012-02
