Overview
  • OSHA Alliance Program
  • OSHA Alliance Program Construction Roundtable
  • U.S. Construction Accident and Fall Statistics
  • Safe Practices
  • Resources
  • Summary

Through the OSHA Alliance Program, this
presentation was developed by members of the
Alliance Program Construction Roundtable for
informational purposes only. It does not
necessarily reflect the official views of OSHA or
the U.S. Department of Labor . (September 2008)

Alliance Program
  • OSHA and the participating organizations
    define, implement,
    and meet a set of
    short- and long-term
    goals that fall
    into three
    categories
  • Training and education
  • Outreach and communication
  • Promoting the national dialogue
    on safety and
    health
  • Sharing technical expertise,
    developing and
    disseminating
    compliance assistance
    products
    with participants
  • Provides OSHA access to millions
  • of employers and employees

John R. Miller, President, SIA. Edwin G. Foulke,
Jr., Assistant Secretary, USDOL-OSHA and Richard
J. Marshall, then-Executive Vice President, SIA
sign a national Alliance agreement on February
25, 2008

U.S. Construction Accident Statistics1
  • Nearly 200,000 serious injuries and 1,226 deaths
    each year
  • 5.5 of workforce but 21.5 of fatalities
  • Construction has one of the highest fatality
    rates of any industry sector
  • SIGNIFICANCE NEARLY 100 DEATHS PER MONTH
  • 1 Bureau of Labor Statistics-2006

11
Fall Speed vs. Reaction Time
In 1 second your body will fall 16 feet
Good body reaction time 0.5 seconds
Travel distance in 0.5 seconds 4 feet
By the time you react your body will be 4
feet below where you were standing
12
  • When Do You Need Fall Protection?
  • OSHAs Regulation 29 CFR 1926.501 (b) under
    Subpart M requires fall protection wherever the
    potential to fall six feet or more exists.
  • Fall protection is required when you are
  • Near an unprotected roof edge
  • Working in a unguarded mezzanine and balcony
    edges

13
When Do You Need Fall Protection?
  • Fall protection is also required in the following
  • locations
  • Working off aerial lift
  • Unguarded scaffolding 10 feet or higher

14
Reducing Fall Fatalities and Injuries
  • Design Professionals Design Professionals need
    to be cognizant to design with health and safety
    in mind. Design permanent building features so
    that fall protection is not needed. This
    eliminates the chance of an accident if fall
    protection is not provided, provided but not
    used, or not used properly
  • Contractors It is the contractors
    responsibility to enforce compliance with safety
    practices with regard to ladders, scaffolds, and
    instances where fall protection is necessary
  • Workers It is the workers responsibility to
    apply the safety practices with regard to
    ladders, scaffolds, and instances where fall
    protection is necessary

15
Types of Fall Prevention and Protection Systems
  • Passive Systems prevent falls by placing a
    physical barrier between the worker and the
    hazard (e.g. guardrails).
  • Active Systems protect workers by limiting the
    fall to a specified distance and also limit the
    amount of force the worker is subjected to in the
    event of a fall (e.g. personal fall arrest
    systems).

16
Personal Fall-Arrest Systems
  • A Personal Fall-Arrest System is a system used to
    arrest an employee in a fall from a working
    level.
  • Any person ordered to work with at height who has
    an increase risk of falling off of
    structures/buildings should wear a personal
    fall arrest system.

17
Personal Fall-Arrest Systems
  • Personal Fall-Arrest Systems, when
  • stopping a fall shall be rigged such that
  • a worker can neither free fall more than
  • six feet, nor contact any lower level.
  • Must have a minimum breaking strength of 5,000
    pounds.

18
  • Personal Fall-Arrest Systems
  • A personal fall-arrest system shall consist of
    the following
  • Anchorage points, Full body harness, Shock
    Absorbing Lanyard, Lifeline, Rope-grabs,
    Connectors
  • All components of the fall arrest system shall be
    fully compatible.

19
Full Body Harness
  • Must be the right size for you.
  • The attachment point of a body
  • harness shall be located on the
  • Rear D-ring between shoulders when working from a
    suspended scaffold or an aerial lift Front D-ring
    when working from a bosuns chair.
  • Harness must be adjusted snugly starting with leg
    straps, then waist, shoulders and chest.

20
Lanyards
  • Used to connect a body harness
  • to a lifeline, rope-grab, or
  • anchorage point.
  • Shall be the appropriate length
  • Bosuns chair 2 feet or less
  • Suspended scaffold 3 to 4 feet
  • Aerial lift 4 to 6 feet
  • Attach to
  • Rear D-ring on harness between shoulders
  • when working on suspended scaffolds and
  • aerial lifts.
  • Front D-ring when working from a bosuns chair.
  • Be protected against being cut or abraded.

21
Lifelines
  • Vertical - connected to an anchorage at one end
    to hang vertically.
  • Horizontal - connected to anchorages at both ends
    to stretch horizontally.

22
Lifelines
  • Are used as a means of connecting other
    components of a Personal Fall-Arrest System.
  • Shall be protected from contact with any surface
    that may abrade, weaken, damage or sever it.
  • Shall be removed from service as recommended by
    the manufacturer.

23
Falls From Roof Edge
24
Falls From Roof Edge-Specify Parapets
  • IBC paragraph 704.11.1 requires that a parapet
    wall be at least 30 inches high
  • OSHA 1926 Subpart M requires a 39-45 inch
    guardrail or other fall protection
  • If the design professional specifies a 39-45 inch
    high parapet wall, fall protection would not be
    required

25
Falls From Roof Edge
  • Other features that Design Professionals should
    consider
  • Locate mechanical equipment away from the roof
    edge or on the ground

26
Design Permanent Anchorage Points
Design Professionals can design fixed anchorage
points so that workers will have a convenient,
safe point to tie off when personal fall arrest
systems are needed.
27
Design of Anchorage Points
  • An anchorage is a secure point of attachment for
    lifelines lanyards or deceleration devices
  • Must be independent of any anchorage being used
    for equipment tiebacks
  • Must be independent of the means of
  • supporting or suspending the worker
  • Must be capable of supporting at
  • least 5,000 pounds per worker
  • Sound anchorages include certified
  • roof anchors as well as structural
  • members.

  • Perimeter guarding shall consist of a mid-rail,
    top rail, toe-board system. The top edge height
    of the rail shall be 42/-3 inches and the
    mid-rail should be between the top and the
    walking/working level.

  • Install a cover for temporary floor openings and
    holes

44
Falls From Structural Steel
45
Falls From Structural Steel
  • Avoid hanging connections design to bear on
    columns instead using safety seats
  • Require holes in columns for tie lines 21 and
    42 above each floor slab
  • Specify shop welded connections instead of bolts
    or field welds to avoid dangerous positions
    during erection
  • Consider approximate dimensions of connection
    tools to prevent pinches or awkward assemblies
