1 Fall Protection in the Roofing Industry
Trainer’s Notes: Duration: 1.0 Hr Presentation limited to OSHA fall protection requirements for roofing activities

2 SUBPART M Fall Protection for Roofing Overview Relationship of Subpart M (Construction) with other OSHA fall protection requirements Fall protection requirements in Construction, Subpart M specifically for roofing activities Multi-employer citation policy Q&A Trainer’s Notes: Ask the participants for experience with falls and fall hazard situations.

3 Two approaches on safety for falls:
SUBPART M Fall Protection for Roofing Two approaches on safety for falls: Fall Prevention – prevents employee from falling (e.g., guardrails, fall restraint systems, covers, skylight screens, warning lines, safety monitor) Fall Arrest – safely catches employee after they have fallen and before they strike a lower level. (e.g., personal fall arrest systems, positioning device systems, safety nets) Trainer’s Notes: Very important for the participants to understand that both have their place, depending upon circumstances, but preventing the vertical is always better if possible.

4 SUBPART M Fall Protection 1st Question- Is the work being performed either inspection, investigation, or assessment prior to the start of construction work or after completion of the construction work? If it is, Subpart M does not apply and fall protection is not required during these activities. Trainer’s Notes: Use as example – What methods can we use here?

5 Fall Protection Requirements
SUBPART M Fall Protection for Roofing Fall Protection Requirements (Subpart M, 29 CFR – 503) Most work 6 feet above levels to which you could fall (primarily based on type of work activity or exposure condition): Ramps, runways, walkways, excavations, hoist areas, holes, formwork, reinforcing steel, leading edges, unprotected sides or edges, overhand bricklaying, roofing, pre-cast concrete erection, wall openings, residential construction, and other walking/working surfaces. Trainer’s Notes:

6 SUBPART Scope of Subpart M M Fall Protection for Roofing Subpart M is like the general duty clause for fall protection in Construction (i.e., it covers fall protection when not specifically addressed by another standard). For example, it does not cover: employees on: scaffolds (Subpart L); personnel platforms on a scaffold, crane or mobile equipment; stairways and ladders (Subpart X) following activities: steel erection (Subpart R), towers & tanks erection( ), electrical power generation, transmission & distribution (Subpart V) Trainer’s Notes:

7 Fall Protection for Roofing Work
SUBPART M Fall Protection for Roofing Fall Protection for Roofing Work Roofing Work is defined in Subpart M as: hoisting, storage, application, and removal of roofing materials and equipment, including related insulation, sheet metal, and vapor barrier work, but not including construction of the roof deck. Subpart M covers fall protection for employees performing roofing work except when such employees are on equipment covered by another standard (e.g., scaffolds, personnel platforms, aerial lifts, stairways & ladders). Employees involved in roofing work on steel erection sites are covered by Subpart R when such roofing work is performed during and as a part of the steel erection work (roofing material must serve as a structural component, such as could occur with some standing seam metal roof installs). Trainer’s Notes: Different methods for different roofing systems. Note single tie-off here and no tie-off in the JLG.

8 Holes (501(b)(4))- 2” or more MORE PEOPLE FALL THROUGH ROOFS THAN OFF OF THEM!!!!
Trainer’s Notes: Discuss what to do with a hole that has just been created and will be repaired in a short time. Is there still a fall hazard? What should be done about it in the period that it is open, regardless of how short a time? Protection must be provided as soon as hole is created; protection prevents employees from tripping in or stepping into hole or falling into hole by either: Cover over Guardrail around Personal fall arrest system (PFAS) for employees Restraint system to keep workers away from fall hazard

9 SUBPART M Fall Protection for Roofing Hole Cover Requirements Also must provide falling object protection if employees below Cover all floor, ceiling, or working surface holes, including skylights, that are larger than 2 inches. - Must support twice the weight of loads imposed at one time. - Secure from horizontal displacement. - Marked “hole” or “cover.” - Must cover hole as soon as created Trainer’s Notes: Floor holes, including skylights, especially in roof decks are a source of numerous fatalities. You may want to refer to the NIOSH Alert.

10 Preventing Falls Through Roof Holes
SUBPART M Fall Protection for Roofing Preventing Falls Through Roof Holes Inadequate “cover” Trainer’s Notes: Reinforce the point with real roof deck situation photos. Skylights or larger deck holes can be covered, surrounded by barriers or have nets put underneath.

11 Floor/Deck Hole Covers
SUBPART M Fall Protection for Roofing Floor/Deck Hole Covers Trainer’s Notes: The OSHA regulation requires covers for any hole bigger than 2” . Ask: What ways are there for something bad happen when hole are not covered? Possible answers: Falling through, stepping in, dropping material/tools through, vehicle wheel falling in, etc. Secured? Clearly Marked? Capable of supporting 2X weight imposed?

12 Protecting Openings/ Skylights & Bad Decking
Requirements Must be protected with: 3/4” Plywood Covers Twice the expected load Tables Fall Protection Skylight Nets Guardrails

13 Protecting Openings/ Skylights & Bad Decking
Skylight Protection Tables Covers Nets Flagged off

14 SUBPART M Fall Protection for Roofing For roofing activities, Subpart M breaks down the allowed fall protective measures (other than for holes) into two categories: residential (b)(13) non-residential (b)(10 & 11) Guardrail Systems Controlled Access Zones Warning Line Systems Safety Monitoring Systems Personal Fall Arrest Systems Hole Covers Canopies Trainer’s Notes:

15 Basic Criteria for Both
SUBPART M Fall Protection for Roofing Basic Criteria for Both Either provide conventional fall protection; i.e., PFAS, safety net, or guardrails; or follow the alternative protective procedures allowed (to be presented later). For Non-residential roofing, alternative protective procedures are allowed only for low slope roofs (i.e., < 4:12). In other words, steep slope roofs require conventional fall protection ie. Guardrails, safety nets or personal fall arrest system. (501(b)(11)). Trainer’s Notes: It is important to discuss all options and relate to roofing situations.

16 Slope = ------------------ In this example, the slope is 2 and 12
Determining Slope The run will always be twelve (12) inches The following is an example of a slope measurement: Rise = 2" Slope = Run = 12" 2" 12" In this example, the slope is 2 and 12

17 Low Sloped Roofs (4 and 12 or less)
Any roof with a slope of 4 and 12 or less is considered low sloped. Greater than 4 and 12 is steep slope. The following fall protection systems can be used on a low sloped roof: If < 50 ft width or less, then safety monitor alone is allowed (no mechanical equipment 502(h)(2)). For >50 ft width, either: Warning line and safety net Warning line and guardrail Warning line and PFAS, or Warning line and safety monitor

18 Walkway to Work Area Walkways must: Have clear access
Protect against hazards Designate area Be reviewed with Crew

19 Guardrail System Method of CONVENTIONAL FALL PROTECTION
Top rails must be between inches high and withstand a lateral force of 200 lbs. A midrail must be placed between the top rail and the work platform and be able to withstand a force of 150 lbs. When using wire rope as a guardrail the following criteria must be met: There must not be more than a 2 inch deflection when a force of 200 lbs. is applied against it in any direction Top rail must be flagged every 6 feet Must have a toeboard to prevent debris from falling off roof (if there is no parapet wall) Must be a minimum of four feet on each side of a material handling area

20 Guardrail Requirements
SUBPART M Fall Protection for Roofing Guardrail Requirements Subpart M ( (b))

21 Manufactured Guardrail Systems
This is one type of available guardrails for use on flat roofs.

22 Too much Sag?

23 Toeboards M Fall Protection for Roofing
SUBPART M Fall Protection for Roofing Toeboards Toeboards prevent tools or materials from becoming falling objects. Store materials minimum 10’ from edge. Add screen or mesh if tools or materials extend above toeboards.

24 Personal Fall Arrest Systems (PFAS)
SUBPART M Fall Protection for Roofing Personal Fall Arrest Systems (PFAS) Method of CONVENTIONAL FALL PROTECTION Components Trainer’s Notes: Point out that all harnesses and lanyards must be made out of synthetic materials. If one of these parts fails, the system fails.

25 PFAS Anchorage Requirements
SUBPART M Fall Protection PFAS Anchorage Requirements Capable of supporting at least 5,000 pounds per attached employee or used as part of an PFAS that maintains a safety factor of at least ‘2’ (designed, installed and used under supervision of a qualified person). Independent of any anchorage being used to support or suspend platforms. Trainer’s Notes:

SUBPART M Fall Protection for Roofing PFAS Devices Trainer’s Notes: Roof bracket Rope grab on a lanyard with deceleration device

27 Sloped Roofing - PFAS Anchorages M Fall Protection for Roofing
SUBPART M Fall Protection for Roofing Sloped Roofing - PFAS Anchorages Trainer’s Notes: Discuss application of PFAS to sloped roofing – obstacles to overcome, reluctance to use it, etc.

28 PFAS Devices Watch swing hazards! M Self-Retracting Lifeline
SUBPART M Fall Protection for Roofing PFAS Devices Limits fall to 2 feet or less Must be attached directly to “D” ring on harness Shock absorber may prevent lock up, or lead to ratchet effect. Line must be protected from damage over edges. Install and inspect in accordance with manufacturer; some will work horizontally,while some will not. Trainer’s Notes: Note that a shock-absorbing lanyard cannot be used with a self-retracting lanyard. Watch swing hazards! Self-Retracting Lifeline

29 PFAS Devices M Fall Protection for Roofing
SUBPART M Fall Protection for Roofing PFAS Devices Trainer’s Notes: You might be able to find examples of roofing situations where in-place maintenance fall protection devices are available. Horizontal Life Lines- must be designed, installed and used under the supervision of a qualified person- maintain a minimum safety of factor of 2
