  10. 10. SAFE DISTANCE? OSHA 1910 OSHA 1926 OSHA 1926 roofing non-roofing Proposed Mech. Equip. 1910 Exception 15 feet de minimis10
  11. 11. OSHA 1910 OSHA 1910 does not provide a safe distance from the edge Proposed OSHA 1910 - Designated area > Perimeter shall be erected no less than 10 feet from the unprotected side or edge11
  12. 12. OSHA 1926: ROOFING OSHA (sec 1926.502(f)(1)ii) - “the warning line shall be erected not less than 6 feet from the roof edge which is parallel… not less than 10 feet…perpendicular to the direction of mechanical equipment operation.” Other exceptions: OSHA (sec 1926.500(a)(2) & 1926.501(b)(1-14)) > Some leading edge work > Precast concrete erection > Residential construction12
  13. 13. OSHA 1926: NON-ROOFING No safe distance OSHA letter of interpretation > For trades other than roofing, warning lines at 15 feet will be a de minimis violation • Roofing Work and Other Trades on Low-Slope Roof (August 1, 2000) • Warning line at 6 feet for HVAC construction workers (November 15, 2002)13
  14. 14. OSHA 1926: NON-ROOFING Warning lines must meet 4 criteria > 15 feet or more from roof edge > Meet or exceed OSHA 1926.502(f)(2) > No work activity within 15 feet of roof edge > Work rules prohibit workers from going outside warning line14
  15. 15. INTERNATIONAL BUILDING CODE IBC (sec 1012.5) - “Guards shall be provided where appliances, equipment, fans or other components that require service are located within 10 feet of a roof edge.”15

  41. 41. THIS ISN’T WARNING LINE41
  42. 42. DESIGNATED AREAS Proposed OSHA 1910 - Designated area > Work of temporary nature such as maintenance on HVAC > Use warning line as alternative to installing guardrails > Surface slope must be 10 degrees or less > Perimeter shall be erected no less than 10 feet from the unprotected side or edge > Access to designated area must be clear path with warning lines42
  43. 43. PPE Roof edge > Fall restraint or arrest • Rail • HLL • Anchor points with lifeline43
  44. 44. PPE: ANCHORAGE POINTS Fixed anchorage > Structural steel? > HVAC unit? > HVAC curb? Temporary anchorage > Ballasted anchor?44
  45. 45. PPE SOLUTIONS Did you consider? > Anchorage strength > Fall clearance > Swing fall > Proper application > Procedures and training > Rescue45
