Question 1

When installing roof trusses, what precautions must be taken to protect workers on the ground from falling objects?

Accepted Answer

Workers not directly involved in the truss installation must be prevented from standing or walking below or adjacent to the roof opening or exterior walls where they could be struck. As described in OSHA's sample fall protection plan, this fall hazard zone must be kept clear during installation.

Question 2

What are the requirements for workers who are positioned at the peak of a roof to install trusses or rafters?

Accepted Answer

Workers at the peak of a roof installing trusses must be trained for the task and work from a stable position. According to OSHA's sample fall protection plan, stability can be achieved by using a "ridge seat" or by positioning themselves within previously stabilized trusses and reaching through them. They should also have no other duties and must not remain at the peak any longer than necessary.

Question 3

Under what weather conditions must roof sheathing operations be suspended?

Accepted Answer

Roof sheathing work must be suspended during wet weather like rain, snow, or sleet, unless safe footing can be guaranteed. Additionally, as noted in the sample fall protection plan which helps comply with Subpart M, operations must stop when strong winds exceed 40 miles per hour, unless effective wind breakers are erected.

Question 4

What is a slide guard and what are the requirements for using one during roof sheathing work?

Accepted Answer

A slide guard is a device used on sloped roofs to help prevent workers from sliding down the roof surface. According to OSHA's sample fall protection plan, slide guards must be constructed of material at least a nominal 4 inches high. They must be securely attached to the roof at intervals not exceeding 13 feet as new rows of sheathing are installed.

Question 5

Does the required spacing for slide guards change for steeper roofs?

Accepted Answer

Yes, the required spacing for slide guards becomes tighter on steeper roofs to provide adequate protection. For roofs with a pitch greater than 9 in 12 (9 inches of vertical rise for every 12 inches of horizontal run), slide guards must be installed at intervals of every four feet, as recommended in OSHA's sample fall protection plan.

Question 6

Who is responsible for identifying the area where workers could be struck by falling objects during roof sheathing installation?

Accepted Answer

A competent person is responsible for determining the limits of the area where workers could be struck by falling objects during sheathing operations. This designated danger zone must be clearly communicated to all workers before the first piece of sheathing is placed, as outlined in the sample fall protection plan which supports compliance with fall protection standards in § 1926.502.

Question 7

When installing floor joists, how can we create a safe working platform to prevent falls?

Accepted Answer

A safe working platform can be created by laying a sheet of plywood over previously secured floor joists or trusses. After the first joists are secured from the ground or a ladder, each successive joist can be installed by workers positioned on this temporary platform, as described in the sample fall protection plan. This method helps address leading edge fall hazards covered under § 1926.502.

Question 8

What is the rule for workers who are near a leading edge but not directly involved in its construction?

Accepted Answer

Workers who are not assisting in leading edge construction must not be permitted within six feet of the unprotected edge. This requirement, found in the sample fall protection plan, creates a limited access zone to protect other workers, such as those cutting decking for the installers, from fall hazards.

Question 9

What is a simple way to warn workers about an unprotected edge when erecting exterior walls on a deck?

Accepted Answer

A simple and effective way to warn workers is to mark a painted line on the deck six feet from the perimeter before wall erection begins. This visual warning, mentioned in OSHA's sample fall protection plan, serves as a clear reminder of the approaching unprotected edge, helping to prevent falls.

Question 10

Who is authorized to make changes to our company's written fall protection plan?

Accepted Answer

Any changes to the fall protection plan must be approved by a qualified person. According to the guidelines in OSHA's sample fall protection plan, a qualified person must also review the plan as the job progresses to see if improvements are needed. This aligns with the requirements for written fall protection plans in § 1926.502(k)).

Question 11

Where should our written fall protection plan be kept during the project?

Accepted Answer

A copy of the fall protection plan, including any approved changes, must be maintained at the jobsite. This ensures that it is accessible to employees, supervisors, and OSHA compliance officers, as specified in the requirements for plans under § 1926.502(k)) and exemplified in the sample plan.

Question 12

To minimize fall risks during floor sheathing installation, how should materials be managed?

Accepted Answer

Materials for floor joist and sheathing operations should be conveniently staged to allow for easy access and minimize worker movement near fall hazards. As suggested in the OSHA sample fall protection plan, proper material staging is a key part of planning work to reduce exposure to leading edge fall hazards.

Question 13

When erecting exterior walls, what steps can be taken to reduce time spent working near the edge of the deck?

Accepted Answer

To reduce time spent near an unprotected edge, workers should complete as much preparation as possible away from the edge of the deck. This includes cutting materials and other preliminary tasks, as recommended in the sample fall protection plan. This proactive measure is a critical component of a fall protection plan under § 1926.502(k)).
