ATTENTION
  • As of January 1, 2005, the Interim Fall
    Protection Guidelines for residential
    Construction are no longer in force. All
    residential fall protection must meet the
    criteria outlined in Subpart M
  • 1926.500, 1926.501, 1926.502, 1926.503

3
Fall protection plan
  • This option is available only to employees
    engaged in
  • leading edge work,
  • precast concrete erection work,
  • or residential construction work (See
    1926.501(b)(2), (b)(12), and (b)(13))

4
Fall protection plan
  • Employer must demonstrate that it is infeasible
    or it creates a greater hazard to use
    conventional fall protection equipment.
  • The fall protection plan shall be prepared by a
    qualified person and developed specifically for
    the site where the leading edge work, precast
    concrete work, or residential construction work
    is being performed and the plan must be
    maintained up to date.

5
Fall protection plan
  • A copy of the plan with all approved changes
    shall be maintained at the job site.
  • The implementation of the plan must ge under the
    supervision of a competent person.
  • The plan shall document the reasons why the use
    of conventional fall protection systems
    (guardrail systems, personal fall arrest systems,
    or safety nets systems) are infeasible or why
    their use would create a greater hazard.

6
Fall protection plan
  • The plan shall include a written discussion of
    other measures taken, such as scaffolds, ladders,
    or vehicle mounted work platforms, to eliminate
    the fall hazard for workers who cannot be
    provided with protection from the conventional
    fall protection systems.
  • See 1926.502(k) for more details on Fall
    Protection Plan
  • Link to sample fall protection plan

(No Transcript)
13
Staging of Materials/Equipment. Materials and
equipment for the work shall be conveniently
located for the workers while performing work at
any height..
14
Impalement Hazards. Materials and other objects
which could pose impalement hazards shall be kept
out of the area below where workers are working
or shall be properly guarded.
15
As of January 1, 2005, this practice is no longer
allowed. Employees working on form work must be
protected by a fall arrest system above 6 feet,
in accordance with 1926.501(b)(5)
.
16
EXCAVATIONS AROUND THE HOUSE FOUNDATION
17
This employee is not protected by a sloping or
shoring system
18
The house foundation/basement excavation must be
benched for at least two (2) feet horizontally
for every four (4) feet or less of vertical
height. In accordance with 1926.652(b)(1)(ii)
19
The minimum horizontal width (excavation face to
form work/wall) at the bottom of the excavation
is as wide as practicable but not less than two
(2) feet.
20
The excavation must be inspected by a competent
person to assure there is no water, surface
tension cracks, or other environmental conditions
present that reduce the stability of the
excavation.
21
The Competent person must also check that there
is no heavy equipment, including loaders and
backhoes, operating in the vicinity that causes
vibration to the excavation walls while employees
are in the excavation AND
22
That all soil, equipment, and material surcharge
loads are no closer in distance to the top edge
of the excavation than the excavation is deep.
Spoils piles shall be placed as far back from the
edge of the excavation as possible, but never
closer than two (2) feet.
23
Work crews in the excavation are the minimum
number needed to perform the work and the work
has been planned and is carried out in a manner
to minimize the time employees are in the
excavation.

OSHA Standards Interpretation Letter from James
Stanley dated 6/30/95
http//www.osha.gov/pls/oshaweb/owadisp.show_docum
ent?p_tableINTERPRETATIONSp_id21846
25
The spoils pile must be placed 2 feet from the
edge of the excavation
This excavation side wall does not meet the
criteria set out in the James Stanley letter.
26
The employer must have Designated, Trained
Workers, when installing floor joist. The
employer must designate the trained workers who
will do this work.
27
Leading Edge WorkWhile this work is taking
place, workers not directly assisting, shall not
be permitted within six (6) feet of the leading
edge.
28
Installation Process Floor Joists/Trusses. The
first floor joist or truss must be rolled into
position and secured by workers on the ground,
ladders, or scaffolds. Successive joists/trusses
must be rolled into place. They are then to be
secured by workers on the ground, ladders,
scaffolds or platforms. The platform is to be
built from a sheet of plywood laid over the
previously secured floor joists or trusses.
29
Installation Process Floor Sheathing. The
first row of floor sheathing must be installed by
workers on the ground, ladders, or scaffolds.
After the first row of sheathing has been
installed, workers shall work from the
established deck.

the ladder in an unsafe manner. ALWAYS face the
ladder when working from it.
35
Walking or standing on the floor joists near the
exterior wall top plate, as the worker is doing,
is not allowed and fall protection must be used
in this situation. The worker must use
scaffolding, a ladder, a wall walker, or other
conventional fall protection methods. This photo
depicts a serious hazard and a violation of 29
CFR 1926.501(b)(1).
36
Warning Line A painted warning line six (6)
feet from the perimeter, will be clearly marked
before any wall erection activities take place.
37
Note This work must be done within a CAZ
(controlled access zone). A crew supervisor/
foreman is required to monitor the work. THE
WARNING LINE DOES NOT REPLACE THE MONITOR.

46
Standard Guardrails for Residential Homebuilding
47
Floor holes (stairway, mechanical chase, or
other) shall meet the requirements of 29 CFR
1926.501(b)(4), which requires the use of either
personal fall arrest systems, covers or guardrail
systems where fall distances are 6 feet or more.
48
1926.502(a)(2) Determine if the walking/working
surfaces on which its employees are to work have
the strength and structural integrity to support
employees safely. Employees shall be allowed to
work on those surfaces only when the surfaces
have the requisite strength and structural
integrity.
49
1926.501(b)(4) Each employee on walking/working
surfaces shall be protected from falling through
holes above lower levels, by personal fall arrest
systems, covers, or guardrail systems erected
around such holes.
50
Floor hole covers
  • All other covers shall be capable of supporting,
    without failure, at least twice the weight of
    employees, equipment, and materials that may be
    imposed on the cover at any one time.
  • All covers shall be secured when installed so as
    to prevent accidental displacement by the wind,
    equipment, or employees.
  • All covers shall be color coded or they shall be
    marked with the word "HOLE" or "COVER" to provide
    warning of the hazard.
  • Toeboards shall be a minimum of 3 1/2 inches (9
    cm) in vertical height from their top edge to the
    level of the walking/working surface. They shall
    have not more than 1/4 inch

51
Stud walls, no matter what the stud OC
dimensions, shall not be considered appropriate
guardrail systems around floor openings
(stairway, mechanical chase, or other) unless top
rails and midrails are installed.
52
Example of a guardrail system around a stairway
opening to the basement that complies with OSHA
regulations. (Stud wall framing, without the
addition of a horizontal top rail and mid rail,
is not sufficient for interior walls to comply
with the regulations.
53
stairways and floor openings must be covered or
railed
Temporary metal guardrail system.
54
Window wells must be covered The cover must be
secured
Illustration of a job-made window well covering.
55
Depicts the dangerous practice of working from
the top plate of the exterior wall while
rolling trusses. The framer has nothing but the
tail end of the truss to hold on to for balance.
The framer is at substantial risk of FALLING!
56
Working off the exterior wall top plate, a
definite hazard and violation of 29 CFR
1926.501(b)(13).

Building truss system on the ground to be lifted
into place with a crane
58
This photo was taken during a snow storm in 1994.
Flying up the truss works in this type of
weather, makes the case for building them on the
ground stronger.

Workers Fall Arrested, Found to be Practicing
Good Safety
Readying to repair a barrel roof with a steep
slope, Rogelio donned his stretchable full-body
harness and tied off to a roof anchor system that
included a four-point mounting assembly with a
rope grab, lifeline and shock-absorbing lanyard.
Rogelio stepped on a board that slipped out of
place, and he lost his footing. He fell and slid
off the edge of the roof, but his fall protection
arrested the descent. Fellow employees grabbed
his deployed lanyard and assisted Rogelio up
onto the roofuninjured. ISEA Summer report
