  1. RESIDENTIAL FALL HAZARDS Susan Harwood Training Grant

  2. This material was produced under grant number SH-22248-11 from the Occupational Safety and Health Administration, U.S. Department of Labor. It does not necessarily reflect the views or policies of the U.S. Department of Labor, nor does mention of trade names, commercial products, or organizations imply endorsement by the U.S. Government.

  3. Residential Construction Fall Hazards All sites have unprotected sides and edges, wall openings, or floor holes at some point during construction.

  4. Residential Construction Fall Hazards Each employee on walking/working surfaces shall be protected from falling through holes

  5. Residential Construction Fall Hazards These workers are installing a floor joist to a header. Both workers are exposed to a fall of 6 feet or more without fall protection

  6. Residential Construction Fall Hazards This worker is standing on the top plate to set a roof rafter. The worker is exposed to an interior and exterior fall hazard.

  7. Residential Construction Fall Hazards Each employee on walking/working surfaces shall be protected from falling through openings

  8. What you will learn • The worker will be able to identify fall hazards on residential construction worksites • The worker will be able to identify corrective actions for fall hazards during different phases of construction • The worker will be able to use this resource to recognize best, safe work practices

  9. Course Overview • Intent of this course • Prevent falls through a focus on safe work practices • Identify fall hazards present during each phase of construction • Identify techniques and the equipment necessary to work safely on residential construction sites when exposed to fall hazards.

  10. Course Overview • What this course is not intended to do • Replace worksite specific, fall hazard training on your current and future worksites • Address all fall hazards on your current and future worksites • Address all types of fall protection that you will be using on the worksite

  11. “We cannot tolerate workers getting killed in residential construction when effective means are readily available to prevent those deaths.” “Fatalities from falls are the number one cause of workplace deaths in construction.” Dr. David Michaels, Assistant Secretary of Labor for OSHA

  13. Residential Fall Protection Requirements Effective September 15, 2012, employers utilizing alternative fall protection found in the rescinded 1999 Interim Fall Protection Compliance Guidelines for Residential Construction will be subject to OSHA citations if they fail to comply with 29 CFR 1926.501(b)(13).

  14. Residential Fall Protection Requirements • Why the rescission of the Interim Fall Protection Compliance Guidelines ? • Never intended to be a permanent resolution. • Fall protection is safe and feasible for the vast majority of residential construction activities. • The residential fall protection requirements have always been established in Subpart M at 29 CFR 1926.501(b)(13).

  15. Residential Fall Protection Requirements • Under the new directive employers must follow 1926.501(b)(13). • 1926.501(b)(13) states … workers “engaged in residential construction activities 6 feet (1.8 m) or more above lower levels shall be protected by guardrail systems, safety net system, or personal fall arrest system.” • … or, by alternative fall protection measures allowed under 1926.501(b) for particular types of work.

  16. Fall Protection Systems Conventional Fall Protection Systems Specialized Fall Protection Systems Safety Monitor Warning Line Controlled Access Zones Fall Protection Plan • Guardrails • Personal Fall Arrest Systems • Safety Nets • Hole Covers

  17. Guardrail Systems 1926.502(b) Conventional Fall Protection Systems

  18. Guardrail Systems1926.502(b) • Requirements for guardrail systems include: • Top rails 42” +/- 3” • Must withstand 200 pounds – 1926.502(b)(1) & 1926.502(b)(3) • Mid rails halfway • Must withstand 150 pounds – 1926.502(b)(2)(i) & 1926.502(b)(5) • Guardrail surface to prevent punctures, lacerations and the snagging of clothing – 1926.502(b)(6) • No steel or plastic banding – 1926.502(b)(8)

  19. Slide guards are not fall protection Workers are exposed to fall hazards as they grasp sheathing.

  20. Rake edge and eave fall hazards While slide guards may prevent sliding, they will not protect workers from falling

  21. Guardrail Systems • 2nd floor perimeter completely protected by a guardrail system.

  22. Guardrail Systems • A pre-fabricated wall panel positioned for installation behind a fully protected area

  23. Guardrail Systems • Guardrails positioned prior to sheathing and left in place. • Proper coordination can serve the needs of several trades.

  24. The landing at the top of the stairs is more than 6 feet above and has no guardrails in place. The staircase is also missing the required guardrails.

  25. Guardrail Systems staircases, stairway openings, and unprotected sides of floors

  26. Guardrail Systems • properly installed guard/hand rails using a “safety boot” system to position the uprights installed during framing.

  27. Guardrail Systems • Brackets for engineered guardrail systems can either be side mounted or deck mounted. • Install according to manufacturer instructions or the recommendations of a registered professional engineer for proper installation.

  28. Note: no protection for the rake edge so some means of protecting this worker (guardrail, safety nets or PFAS) must be used.

  29. Personal Fall Arrest Systems 1926.502(d) Conventional Fall Protection Systems

  30. Personal Fall Arrest System • A Personal Fall Arrest System (PFAS) must include the following components: • Anchorage • Body Harness • Connector/Lanyard

  31. Personal Fall Arrest SystemAnchor Point • 1926.502(d)(15): Anchorages for attachment of PFAS must be capable of supporting at least 5,000 pounds per employee • under supervision of a qualified person. • installed according to manufacturer – PFAS system needs to maintain a safety factor of at least two.

  32. manufactured anchor system that is being used with a PFAS until floor sheeting is secured to the joists

  33. An approved elevated mounting bracket to be used with a Self-Retracting Lifeline (SRL) system anchorage that is used to work on a floor edge that is moving

  34. D-Ring Anchor Point for use at roof peak or rafter/truss

  35. Installation of anchors More than one anchor point may be necessary to limit swing distances. An anchor is needed for each worker

  36. PFAS in use during roofing and re-roofing activities.

  37. Personal Fall Arrest SystemFull Body Harness • A full body harness distributes the force of the fall over the thighs, pelvis, waist, chest and shoulders

  38. Personal Fall Arrest SystemFull Body Harness • The attachment point on a full body harness is a D-ring in the center of your upper back. • Be sure to use a size that fits properly

  39. Inspection What is this worker doing?

  40. HARNESSES Look for same damage as on lanyards Also, deformed or damaged hardware, grommets and buckles Inspection • LANYARDS • Look for frayed or broken strands • Also, burns, cuts, and hard spots from chemical damage

  41. Personal Fall Arrest SystemFull Body Harness Which worker is wearing the harness correctly?

  42. Snaphooks must be locking type – 1926.502(d)(5). Never hook two snaphooks together unless designed for that purpose – 1926.502(d)(6) Connector / Lanyard

  43. A truss system braced and the first row of sheathing secured can provide a safe anchor point. Note: This is not safe to use until the trusses are secured

  44. The worker installing OSB is using a vertical lifeline, a rope-grab lanyard, and a full body harness

  45. PFAS in use during roofing and gutter installation

  46. Rescue Plan • After a fall, a worker may not be able to rescue themselves and may remain suspended in a harness. • A rescue plan should be in place to retrieve a suspended worker as soon as possible after a fall. • A worker is at great risk of developing a condition known as "suspension trauma" if left suspended by a harness for a prolonged period. • Suspension trauma is a serious condition and can even be fatal. Onset of symptoms of suspension trauma can occur as little as 5 minutes after a fall.

  47. Safety Nets 1926.501(c) Conventional Fall Protection Systems

  48. Safety Nets • Safety nets must be installed as close as practicable under the surface on which employees are working • Safety nets must be installed with sufficient clearance to prevent contact with the surface or structures under • Safety nets and safety net installations must be drop-tested at the jobsite
