There are four groups of residential construction activities for which alternative fall protection plans are available. Each group has its own set of alternative procedures and will be discussed in Sections IX through XII. The groups are:
The alternative measures for this group are set out in Appendix E to Subpart M. Appendix E requires the employer to implement a Fall Protection Plan. Such a plan must lay out the safest procedures to be followed at the work site to prevent falls. Although the plan need not be in writing, it must be communicated to all employees on site who might be subject to fall hazards.
NOTE: Height Limitation: The Appendix E plan may only be used on structures up to three and a half stories or 48 feet (including basement, two finished levels, attic). The 48' measure is from the base of the building, at the lowest ground level (including any excavation), to the point of greatest height. The following are the required elements of the Plan:
Each employee performing work in Group 1 activities must be trained in the requirements of the Plan. The employer must ensure that the employees (1) understand the procedures and follow the instructions of the crew supervisor or foreman; (2) are able to recognize unsafe/hazardous conditions and are to report them to the employer; (3) can recognize when compliance with the Plan would create a greater hazard and are instructed to inform the Competent Person before proceeding when that occurs. Training and retraining violations shall be cited under 29 CFR 1926.503(a) and 1926.503(c). Subsection 1926.503 (b) may not be cited for residential construction.
NOTE: Any concerns raised by employees at any time during construction must be addressed (determined to be valid or not) before work proceeds.
a. Competent Person.
The employer must designate a Competent Person, who will be charged with implementing the Plan. The Competent Person must continually monitor compliance with the Plan, including the provision of training and the proper use of Controlled Access Zones.
b. Qualified Person.
The employer must designate a qualified person to approve any changes to the Plan.
c. Crew Supervisor/Foreman.
The employer must designate a crew supervisor or foreman and charge him or her with the responsibility of immediately correcting any unsafe practice or condition.
For purposes of this Instruction, a Controlled Access Zone (CAZ) restricts access to a clearly designated area where a Group One activity (installation of floor joists, floor sheathing, roof sheathing; erecting exterior walls; setting and bracing roof trusses and rafters) is taking place. The CAZ must meet the following requirements:
The competent person shall determine the boundaries of the CAZ and clearly mark them with signs, wires, tapes, ropes or chains.
The crew supervisor/foreman shall monitor the workers in the CAZ to ensure that they do not engage in unsafe practices.
c. Restricted Access.
Access to the CAZ must be restricted to authorized entrants. An authorized entrant is a worker who has received the training described above. The competent person must identify each entrant as an authorized entrant after the employee has successfully completed the training.
d. Final Check.
Before work begins in the CAZ, the competent person must ensure that all protective measures in the Plan have been implemented.
(1). Walls over 8 feet. General requirements.
(a)Falling Objects/Restricted Access.
Once truss/rafter installation begins, workers not involved in that activity shall not stand or walk below or adjacent to the roof opening or exterior walls in any area where they could be struck by falling objects.
Trusses/rafters must be adequately braced before any worker may use them as a support.
(c) Designated, Trained Workers.
The employer must designate the trained workers who will work on the top plate, and those who will work on the peak.
(d) Restricted Duties.
Top plate workers shall have no other duties during truss/rafter erection.
(2) Procedures for working on the top plate.
(a) Installing The First Two Trusses.
The first two trusses/rafters must be set from ladders. The ladders must lean on side walls at points where the walls can support the load imposed by the ladder and worker. After the first two trusses/rafters have been set, a worker will climb a ladder onto the interior top plate to secure their peaks.
(b) Remain On The Top Plate.
Workers will remain on the top plate and use the previously stabilized trusses/rafters as support while the other trusses/rafters are erected.
(3) Procedures for working at the peak.
(a) When Workers May Work On Peaks/Ridge Beam.
Workers detaching trusses from cranes or securing trusses at the peaks may be positioned at the peak of the trusses/rafters. Workers may be stationed on the top of the ridge beam where that is the only feasible way to secure rafters to the ridge beam.
(b) Stable Work Position
Workers at the peak, in the web of trusses, or on top of the ridge beam shall work from a stable position. They must either sit on a ridge seat (or the equivalent) or position themselves in previously stabilized trusses/rafters and lean into, and reach through, the trusses/rafters.
(c) Limited Fall Hazard Exposure.
Workers must not remain on or in the peak/ridge any longer than necessary to complete the task safely.
-- Bottom Row: The bottom row of roof sheathing may be installed by workers standing in truss webs and leaning over the sheathing. After the bottom row is installed, a slide guard of at least four (4) inches nominal in height shall be securely attached to the roof. It must extend across the full width of the roof.
-- Slide Guard Intervals: Roof Pitch Up To (and including) 9 in 12: Additional slide guards are required at 13 foot intervals as successive rows of sheathing are installed.
-- Slide Guard Intervals: Roof Pitch Over 9 in 12: Additional slide guards are required at four foot intervals.
NOTE: These slideguard requirements, which come from Appendix E, differ from those for Group 4 Activities (roofing work).
NOTE: As discussed above, this work must be done within a CAZ. A crew supervisor/foreman is required to monitor this work and warn anyone who approaches the unprotected edge. The warning line does not replace the monitor; it is an additional safety measure.
NOTE: Wall openings (more than six feet above the lower level), floor holes and roof holes: As soon as sheathing has been installed around a floor hole, roof hole, or wall opening that is not going to be sheathed (such as a hole for a doorway, stairwell or skylight), it must be covered, or protected by a guardrail.
This Instruction specifies the alternative procedures for protecting employees working from the top surface of block foundation walls, concrete foundation walls, and related form work. These procedures are:
This Instruction specifies the procedures for this group. They are:
NOTE: The provisions of this Instruction do not apply to interior finishing work when done outside of attics or roofs areas. Subpart M applies to such work with respect to stairways, stairway openings, walkways, floor or window openings, floor holes or other elevated openings or open sides.
Restriction on Application for Roofing Work. The alternative procedures in this Instruction may only be used for this work where: (a) the roof slope is 8 in 12 or less, and (b) the fall distance, measured from the eave to the ground level, is 25 feet or less.
If an employer (engaged in residential construction) does not provide conventional fall protection, the compliance officer must determine if STD 3-0.1a provides alternative procedures for the activity in question. If alternative procedures are available, the compliance officer must determine if they have been implemented. If there is a deficiency in the implementation of the alternative procedures, the fall hazard shall be cited as a violation of 1926.501(b)(13). No other provision may be cited for a fall hazard addressed by 1926.501(b)(13). Deficiencies in training required by 1926.20 may also be cited where appropriate.
