Title: Hazard Assessment

Hazard Assessment
Why Hazard Assessment?
  • 29 CFR Part 1910. Subpart I
  • Increases Awareness of Workplace Hazards
  • Provides opportunity to identify and control
    workplace hazards
  • Can lead to increased productivity
  • May prevent an Occupational Injury or Illness

What is PPE?
  • Equipment worn by an employee that is designed to
    prevent injury or illness from a specific hazard.

Before PPE
  • Administrative Controls
  • Change Work Practices
  • Change Hazardous Duties
  • Cease Hazardous Duties
  • Engineering Controls
  • Sound insulation
  • Guards
  • Tools

Administrative Changes ! For Example.... Vs
  • Working off Ladder
  • Oil based paint
  • Sand blasting in booth
  • Jackhammering
  • Gloved hand
  • Working off Scaffold
  • Water based paint
  • Sand blasting in cabinet
  • Hole Ram
  • Hot Sticks

Engineering Controls
  • Machine Guards
  • Sound deadening/dampening
  • Shielding

Controlling Hazards
  • PPE devices alone should not be relied on to
    provide protection against hazards, but should be
    used in conjunction with guards, engineering
    controls, and sound work practices .

Assessment and Selection
  • It is necessary to consider certain general
    guidelines for assessing the foot, head, eye and
    face, and hand hazard situations that exist in an
    occupational operation or process, and to match
    the protective devices to the particular hazard.
    It is the responsibility of the supervisor to
    exercise common sense and appropriate expertise
    to accomplish these tasks.

Assessment Guidelines.
  • Conduct a walk through survey of the areas in
    question. The purpose of the survey (or field
    observation) is to identify sources of hazards to
    workers and co workers.

Hazard Sources
  • sources of MOTION
  • sources of EXTREME temperatures
  • types of chemical exposures
  • sources of harmful dust
  • sources of light radiation
  • sources of falling objects or potential for
    dropping objects
  • sources of sharp objects
  • sources or rolling or pinching objects
  • layout of workplace and location of co workers
  • any electrical hazards

In addition....
  • injury/ accident data should be reviewed to help
    identify problem areas.

Organize data
  • Following the walkthrough survey, it is necessary
    to organize the data and information for use in
    the assessment of hazards. The objective is to
    prepare for an analysis of the hazards in the
    environment to enable proper selection of
    protective equipment.

Analyze data
  • Having gathered and organized data on a
    workplace, an estimate of the potential for
    injuries should be made. Each of the basic
    hazards should be reviewed and a determination
    made as to the type, level of risk. and
    seriousness of potential injury from each of the
    hazards found in the area.
  • The possibility of exposure to several hazards
    simultaneously should be considered.

Selection guidelines
  • Become familiar with the potential hazards and
    the type of protective equipment that is
    available, and what it can do i.e.., splash
    protection, impact protection, etc.
  • Compare the hazards associated with the
    environment i.e.., impact velocities, masses,
    projectile shape, radiation intensities, with the
    capabilities of the available protective equipment

Selection guidelines (cont.)
  • Select the protective equipment which ensures a
    level of protection greater than the minimum
    required to protect employees from the hazards.
  • Fit the user with the protective device and give
    instructions on care and use of the PPE.

Selection Note
  • It is very important that end users be made aware
    of all warning labels for and limitations of
    their PPE

Reassessment of hazards
  • It is the responsibility of the supervisor to
    reassess the workplace hazard situation as
    necessary, by identifying and evaluating new
    equipment and processes, reviewing accident
    records, and reevaluating the suitability of
    previously selected PPE

Job Safety Analysis
  • The breaking down into its component parts of any
    method or procedure to determine the hazards
    connected with each key step and the requirements
    for performing it safely.

Job Safety Analysis Priorities
  • New Jobs
  • Severity Potential
  • History of Disabling Injuries
  • Frequency of Accidents

Job Safety Analysis
  • Job means task
  • (Changing a tire not auto mechanic)
  • key steps
  • too detailed becomes cumbersome
  • not enough detail becomes useless

Break job down into key steps AVOID!!
  • making the breakdown so detailed That an
    unnecessarily large number of steps results
  • making the job breakdown so general that basic
    steps are not recorded

Key Steps TOO MUCHChanging a Flat Tire
  • Pull off road
  • Put car in park
  • Set brake
  • Activate emergency flashers
  • Open door
  • Get out of car
  • Walk to trunk
  • Put key in lock
  • Open trunk
  • Remove jack
  • Remove Spare tire

Key Steps NOT ENOUGHChanging a Flat Tire
  • Park car
  • take off flat tire
  • put on spare tire
  • drive away

Key Job Steps JUST RIGHTChanging a Flat tire
  • Park car, set brake
  • remove jack tire from trunk
  • loosen log nuts
  • jack up car
  • remove tire
  • set new tire
  • jack down car
  • tighten lug nuts
  • store tire jack

  • Parking Car
  • Struck by Traffic
  • Removing tire jack
  • Back Strain
  • bang head on trunk
  • Loosen lug nuts
  • back/arm strain
  • slip fall
  • Jacking up car
  • car could fall off jack
  • Setting new tire
  • fingers pinched
  • back strain
  • Tighten nuts
  • back strain
  • slip fall

Work Observation
  • Select experienced worker(s) who will cooperate
    and participate in the JSA process.
  • Explain purpose of JSA
  • Observe the employee perform the job and write
    down basic steps
  • Completely describe each step
  • Note deviations (Very Important!)

Job Safety Analysis
Identify Hazards Potential Accidents
  • Search for Hazards
  • Produced by Work
  • Produced by Environment
  • Repeat job observation as many times as necessary
    to identify all hazards

Develop Solutions
  • Find a new way to do job
  • Change physical conditions that create hazards
  • Change the work procedure
  • Reduce frequency

New way to do job
  • Determine the work goal of the job, and then
    analyze the various ways of reaching this goal to
    see which way is safest.
  • Consider work saving tools and equipment.

Change in physical conditions
  • Tools, materials, equipment layout or location
  • Study change carefully for other benefits (costs,
    time savings)

Change in work procedures
  • What should the worker do to eliminate the
  • How should it be done?
  • Document changes in detail

Reduce frequency
  • What can be done to reduce the frequency of the
  • Identify parts that cause frequent repairs -
  • Reduce vibration save machine parts

What effects??
  • A job that has been redesigned may affect other
    jobs or work processes.
  • Check or reobserve the new process once it has
    been redesigned
