BOTTOM LINE UPFRONT

Roof fall protection is challenging

＞ Various regulations

＞ Abatement strategies

You need a plan for:

＞ Access and safe distance policies

＞ Hazard identification

＞ Hazard abatement

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 edge

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 construction

13

OSHA 1926: NON-ROOFING

No safe distanceOSHA 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)

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 line

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.”

OSHA STD 1-1.13 – DEFINITION

Any surface designed or used as a walking / working surface

＞For tasks performed on a predictable / regular basis

31

OSHA STD 1-1.13 – REQUIREMENTS

FREQUENT TASKS:

＞ More than 1x every 2 weeks

＞ More than 4 hours over 4 week period

＞ Required to use engineering controls (guardrail)

LESS FREQUENT TASKS:

＞ Permitted to use alternative fall protection such as a personal fall arrest systems (PFAS)

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 lines

43

PPE

Roof edge

＞ Fall restraint or arrest

• Rail

• HLL

• Anchor points with lifeline

44

PPE: ANCHORAGE POINTS

Fixed anchorage

＞ Structural steel?

＞ HVAC unit?

＞ HVAC curb?

Temporary anchorage

＞ Ballasted anchor?

45

PPE SOLUTIONS

Did you consider?

＞ Anchorage strength

＞ Fall clearance

＞ Swing fall

＞ Proper application

＞ Procedures and training

＞ Rescue
