  • FALL ZONE AND

    DANGER ZONEThanks to the many DOE and Private Sector Contributors for the content.

    55 -110

  • We lift frequently in tight spaces with ordinary, special, production and critical lifts.

    Workers and Materials are always at risk.

  • WHY IS FALL ZONE/

    DANGER ZONE

    IMPORTANT?

    Real world. People are dying from lifting accidents and at

    greater numbers than most hazards!!

    .

  • REAL HAZARDS – REAL ACCIDENTS

    An Accident Investigation Board was appointed to investigate the December 19, 2018, construction lifting accident that resulted in serious injuries.

    Worker using forklift to hold elevated metal HVAC frame dropped it ~12 feet—near miss

    2020- Reactor 15-Element Rack Separation During Critical Lift bottom portion of the rack separated from the upper grid plate. The bottom of the rack tipped over.

    Fatal Occupational Injuries Involving Cranes-- From 2011 to 2015, the Census of Fatal Occupational Injuries reported 220 total crane-related deaths, an average of 44 per year over this 5-year period. (BLS)

    Failure of Lifting Points during Lift of Batch Plant Silo

    2017-Girder Dropped During Lift by Mobile Crane

    Lift fixture slipped from the end of telehandler tines and conveyor to the floor

  • FALL ZONE -- DEFINED

    OSHA defines- in 1926.1401- Fall zone means the area (including

    but not limited to the area directly beneath the load) in which it is

    reasonably foreseeable that partially or completely suspended

    materials could fall in the event of an accident.

    Danger Zone not defined specifically in standards. It exists in the

    “not limited to” and addresses reasonably foreseeable fall or

    energy release. “Danger” is a warning term.

  • DANGER ZONE -- DEFINED

    Danger is a Warning word that seeks to get emotional awareness

    Hazard is a condition including a scenario where harm is possible

    Danger Zone is NOT an OSHA defined term for Fall zone and associated hazards

    Dangerous areas is OSHA defined for some crane operations, e.g. 1926.1435

    Concept of DANGER ZONE is to capture workers attention, emotional connection, so each is aware and consider hazards and risks

    Sites often have different warning terms. Teach and apply to site practices

    Danger Zone is ANY area or location potentially impacted by failures or events during the life-cycle process of the lift

    Control hazards and warn of danger

  • CONCEPT – NOT A MATH EQUATION

    Fall Zone is SET by risk owners with

    technical support of Qualified HR Workers

    Hazards are lift dependent and varying

    Danger zone around Fall Zone

    Expect the unexpected

    Danger Zone

    Fall Zone

    FALL ZONE / DANGER ZONE IS NOT AN EXACT

    MEASURED SPACE

  • PLAN TO ADDRESS FALL ZONE /

    DANGER ZONE

    ISMS and Work Planning and Control

  • MINDSET OF DANGER ZONE HAZARDS

    Untrained users may be unaware of the subtlety of “but not

    limited to, directly below the load”.

    Erroneously the focus may be placed solely on the “directly

    below the load” without regard to “but not limited to”.

    Key point -- awareness of the potentially deadly consequences

    of the fall zone must involve more than falling loads. The release

    of tension in any attitude, i.e., vertical (up and down), and/or

    horizontal (to and from), at any angle can result in severe injury or

    death.

  • LIFT PLAN TO

    CONTROL FALL ZONE

    Processes defined in Site Practices

    Apply ISMS

    Work planning and control process applies

    Lift planning process

    Evaluate the Sphere of Influence

    Energy Trace Barrier Analysis tool

    ALARP- no reasonable lower risk alternative

    COMMUNICATE

    Pre-Job= increase understanding of risk/control using diagrams, signs, and instructions to workers.

    Authorize the lift activity

    PRINCIPLES OF INTEGRATED SAFETY MANAGEMENT

    • LINE MANAGEMENT RESPONSIBILITY FOR SAFETY. Line management is directly responsible for the protection of the workers, the public, and the environment.

    • CLEAR ROLES AND RESPONSIBILITIES. Clear and unambiguous lines of authority and responsibility for ensuring safety are established and maintained at all organizational levels within the Department and its contractors.

    • COMPETENCE COMMENSURATE WITH RESPONSIBILITIES. Personnel possess the experience, knowledge, skills, and abilities that are necessary to discharge their responsibilities

    • BALANCED PRIORITIES. Resources are effectively allocated to address safety, programmatic, and operational considerations. Protecting the workers, the public, and the environment is a priority whenever activities are planned and performed.

    • IDENTIFICATION OF SAFETY STANDARDS AND REQUIREMENTS. Before work is performed, the associated hazards are evaluated and an agreed-upon set of safety standards and requirements is established which, if properly implemented, will provide adequate assurance that the workers, the public, and the environment are protected from adverse consequences.

    • HAZARD CONTROLS TAILORED TO WORK BEING PERFORMED. Administrative and engineering controls to prevent and mitigate hazards are tailored to the work being performed and associated hazards.

    • OPERATIONS AUTHORIZATION. The conditions and requirements to be satisfied for operations to be initiated and conducted are clearly established and agreed upon.

  • FACTORS IN EVALUATING FALL ZONE/

    DANGER ZONE

    If you don’t recognize the hazard, you can’t control the load,

    potential fall, or released energy

  • FACTORS IN

    DEFINING

    FALL ZONE /

    DANGER ZONE

    Predict, analyze where load can fall

    Load shape, Center Gravity, size

    Rigging

    Attachment points and order of attachment

    Attaching and unhooking steps

    Height above surface

    Route and range of Motion

    Swinging

    Projectile/Recoil/Released tension

    Load control precision

    Working Slopes, walking conditions

    Weather

    Sphere of Influence

    Every Direction

    Many options for

    energy release

  • EVALUATE THE SPHERE OF INFLUENCE

    As an example, consider a scenario in which a spreader bar is

    used to lift a load and it is connected to the crane with a two-leg

    bridle sling. Imagine the sphere of influence if during use, just one

    of bridle legs were to break. The load may fall “directly below”,

    but the spreader bar, while still connected to the crane with the

    remaining bride leg may be propelled into the “but not limited

    to” zone.

  • DEFINE THE CONTROLS

  • Keep Everyone out of the Fall Zone

    DEFINE clearly in plan when qualified person is allowed in Fall Zone

    -Assigned workers with competencies

    -Specific functions and scope of action

    -Temporary worker exposure to hazard-shortest time

    The better the hoisting and rigging, unexpected energy release is much less likely. Thus hazards in Fall Zone and Danger Zone are more controlled

    Personnel shall not pass under orstand under a suspended load.[ASME B30.9 (2018) 9-5.10.2 (c)]

    Personnel should not stand in line or next to slings under tension.[ASME B30.9 (2018) 9-5.10.2 (b)]

    EXPECTATIONS

  • ”OSHA 1926.1425 for Cranes and Derricks in Construction

    Hoisting routes minimize employee exposure

    No employee in Fall Zone unless hooking or guiding, attaching load, receiving, tilt-up, ...

    OSHA specifics apply-

    rigged by qualified rigger

    self closing hooks or equivalent

    NEVER UNDER – NEVER ON – NEVER IN-LINE.

    Graphics from Mike Gelskey, Sr.

  • OSHA 1926.1425 “Keeping Clear of the Load” regulations detail the requirements and provide

    good guidance. A summary includes:

    Avoid carrying loads over people. Plan the load travel path to minimize exposure to

    individuals on the site.

    When a suspended load is not moving, it is only permissible to have an employee in the fall

    zone if they are:

    hooking, unhooking or guiding the load

    doing the initial attaching of the load to a component or structure; or

    operating a concrete bucket.

    The load must be rigged to prevent unintentional displacement.

    Hooks with self-closing latches or their equivalent must be used.

    The load must be rigged by a qualified rigger.

    When a load is being landed, only employees needed to receive a load are permitted to be

    within the fall zone.

    During a tilt-up or tilt-down operation, no employee must be directly under the load and only

    employees essential to the operation are permitted in the fall zone if it is not feasible for the

    employee to perform that operation from outside the fall zone.
