Effective September 15, 2012, employers utilizing alternative fall protection found in the rescinded 1999 Interim Fall Protection Compliance Guidelines for Residential Construction will be subject to OSHA citations if they fail to comply with 29 CFR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

Residential Fall Protection Requirements

14

• 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).

Residential Fall Protection Requirements

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

• Guardrails• Personal Fall Arrest

Systems• Safety Nets• Hole Covers

Specialized Fall Protection Systems

• Safety Monitor • Warning Line• Controlled Access Zones• Fall Protection Plan

17

CONVENTIONAL FALL PROTECTION SYSTEMSGuardrail Systems1926.502(b)

18

• 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)

Guardrail Systems1926.502(b)

19

Workers are exposed to fall hazards as they grasp sheathing.

Slide guards are not fall protection

20

Rake edge and eave fall hazardsWhile 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

• staircases, stairway openings, and unprotected sides of floors

Guardrail Systems

26

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

Guardrail Systems

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

CONVENTIONAL FALL PROTECTION SYSTEMSPersonal Fall Arrest Systems 1926.502(d)

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 D-Ring Anchor Point for use at roof peak or rafter/trussroof 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

37

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

38

• A full body harness distributes the force of the fall over the thighs, pelvis, waist, chest and shoulders

Personal Fall Arrest SystemFull Body Harness

39

• 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

40

Inspection

What is this worker doing?

41

Inspection

• LANYARDS

– Look for frayed or broken strands

– Also, burns, cuts, and hard spots from chemical damage

• HARNESSES

– Look for same damage as on lanyards

– Also, deformed or damaged hardware, grommets and buckles

42

Personal Fall Arrest SystemFull Body HarnessWhich worker is wearing the harness correctly?

43

• 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

44

45

Note: This is not safe to use until the trusses are secured

• A truss system braced and the first row of sheathing secured can provide a safe anchor point.

46

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

47

• PFAS in use during roofing and gutter installation

48

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.

49

CONVENTIONAL FALL PROTECTION SYSTEMSSafety Nets1926.501(c)

50

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

51

CONVENTIONAL FALL PROTECTION SYSTEMSHole Covers1926.501(b)(4)

52

Hole Covers• 1926.501(b)(4)(i) and (ii) - Covers can be used to

prevent workers from falling through holes.– Vehicular traffic /foot traffic cover must support 2

times the maximum intended load

– Secured to prevent displacement

– Marked with the word “HOLE” or “COVER” or color coded

53

workers are not protected from the large unprotected opening in the middle of the floor

54

Although the standard does not mention personal fall restraint systems, OSHA has previously stated that it accepts a properly utilized fall restraint system in lieu of a personal fall arrest system when the restraint system is rigged in such a way that prevents the worker from being exposed to the fall hazard.

Personal Fall Restraint System

55

• Personal fall restraint is used mainly for edge work• Lanyards should be adjustable to take up slack when workers move about.

56

• Must be tied off so that the worker cannot go past the unprotected side or edge.

57

• 1926.501(b)(2)(ii) - Controlled access zones and control lines can be used for some leading edge applications.

• 1926.501(b)(10) - A combination of a warning line system and safety monitoring system can be used for roofing work on low-slope (4:12 or less) roofs. Or, on roofs 50-feet (15.25 m) or less in width, the use of a safety monitoring system without a warning line system is permitted.

Other Methods Allowed Under 1926.501(b)

58

• If the employer can demonstrate that it is infeasible or creates a greater hazard to use the required fall protection systems, the employer must instead develop and implement a written site specific fall protection plan in accordance with 29 CFR 1926.502(k).

– The Agency does not consider "economic infeasibility" to be a basis for failing to provide conventional fall protection.

• Note: There is a presumption that it is feasible and will not create a greater hazard to implement at least one of the fall protection systems listed in 29 CFR 1926.501(b)(13).

– OSHA expects that the fall protection methods listed in 1926.501(b)(13) can be used without significant safety or feasibility problems for the vast majority of residential construction activities.

Residential Fall Protection Requirements

59

• For a safety monitoring system under 1926.502(h) the monitor must:• Be a competent person.• Warn workers of fall dangers.• Be on same working level and

within visual sighting.• Be close enough to communicate orally.• Not have responsibilities which take attention

away from monitoring.

Fall Protection PlanSafety Monitor Duties

60

• If an employer can demonstrate that conventional fall protection is infeasible or presents a greater hazard– the employer shall develop and implement a fall

protection plan that complies with 1926.502(k).– The employer bears the burden of establishing

that it is appropriate to implement a fall protection plan for a particular workplace situation.

Fall Protection Plan1926.502(k)

61

• Under 1926.502(k) the fall protection plan: – Must be written.– Must be site-specific.

• A written fall protection plan developed for repetitive use, e.g., for a particular style or model of home, will be considered site-specific with respect to a particular site only if it fully addresses all issues related to fall protection at that site.

• Therefore, a standardized plan will have to be reviewed, and revised as necessary, on a site by site basis.

Fall Protection Plan1926.502(k)

62

Fall Protection Plan1926.502(k)• The plan must be prepared by a “qualified person” -

1926.502(k)(1).– "Qualified” means one who, by possession of a recognized

degree, certificate, or professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated his ability to solve or resolve problems relating to the subject matter, the work, or the project - 1926.32(m). (This could be the owner, supervisor, etc.).

• Be developed specifically for the site where the residential construction work is being performed – 1926.502(k)(1).

• Must be maintained up to date – 1926.502(k)(1). • All changes shall be approved by a qualified person –

1926.502(k)(2).

63

Fall Protection Plan1926.502(k)• Shall be maintained on the site – 1926.502(k)(3).• Shall be implemented under the supervision of a competent

person – 1926.502(k)(4).– “Competent Person” means 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 – 1926.32(f). (This could be the owner, supervisor, etc.).

• Shall include documentation of reasons why conventional fall protection systems are infeasible or create a greater hazard – 1926.502(k)(5).

• Shall include a written discussion of the alternative work practices to be used that will eliminate or reduce the possibility of a fall – 1926.502(k)(6).

64

Fall Protection Plan1926.502(k)• Shall identify each location where conventional fall

protection systems cannot be used and designate them Controlled Access Zones (CAZ) – 1926.502(k)(7).

• Implement a safety monitoring system in conformance with 1926.502(h) where no other alternative measure has been implemented – 1926.502(k)(8).

• Shall identify all workers designated to work in the CAZ – 1926.502(k)(9).

• Shall be reviewed and updated as appropriate if a fall, or near miss, occurs – 1926.502(k)(10).
