Hazards to Maintenance Workers
  • Frequent heavy lifting
  • High pressure hoses and vessels
  • Work in awkward or confining spaces
  • Exposure to potentially hazardous substances
    (oil, gas, engine fluids, welding fumes, etc.)
  • Proximity to moving parts, hand tools, and
  • Maintenance work in non-optimum conditions (i.e.
    servicing equipment in the mine instead of the

Tire-Related Fatalities
Tire explosion which resulted in a fatality
Between 1980 and the 2nd quarter of 2001, there
were 31 tire-related fatalities in the mining

Tire-related fatalities account for a relatively
low proportion of occupational fatalities in
mining. However, focused safety, training, and
other prevention efforts should effectively
eliminate this cause of death.

Distribution of 31 fatalities by job-type
72 of tire-related fatalities were to mechanics
and repairmen.
Tire-Related FatalitiesGrouped by Accident Type
Tire Fatalities
  • Explosions In many cases, workers were applying
    heat to the rim or lugs which caused an expansion
    in air pressure in the tire.
  • Safety tips1
  • NEVER apply heat to a rim or rim assembly that
    has an inflated (or deflated) tire mounted on it.
    Even deflated tires may explode.
  • Rough terrain, and malfunctioning or excessive
    braking can also cause heat to build up on a
  • Personnel should stand out of the trajectory of a
    tire when inflating or inspecting the rim
  • The use of barriers or restraining devices is
    recommended where applicable.
  • Do not inflate beyond manufacturer-recommended

Tire Fatalities
  • Tire Fell on Victim Tire was improperly secured
    and tipped over or fell from a height onto the
  • Safety tips
  • Fix tires securely when using boom trucks,
    slings, fork lifts, or bead hooks to move tires.
  • Set tires flat on ground or far enough away from
    personnel that if a tire does tip over all
    personnel are clear. Warning watch for rolling
    tires, and do not walk beneath suspended loads!
  • Lugs, rims, and other accessories on large
    equipment are heavy enough to cause fatal or
    disabling injuries. Use the same precautions
    with these items.

Tire Fatalities
  • Auxiliary Equipment Worker was fatally injured
    when tools or equipment used in tire-related
    activities failed, were used improperly, or were
    the primary source of injury (examples include
    items such as jacks, tire irons, hand tools, boom
  • Safety tips
  • Always use tools in the manner for which they are
  • Inspect jacks, hydraulic lifts, slings, and
    chains before use.
  • Do not work beneath suspended loads or equipment.
  • Secure vehicle with brakes, chocks, etc. to avoid
  • Where possible, work on a clean, dry, flat
    surface. Maintain shop housekeeping.

Instruction Guide 60, available from MSHA.
Tire-Related Injuries
  • 1995-2001.2

About the injury data...
  • Only those records directly linked to tire
    incidents causing reportable, lost-time accidents
    were included in this analysis.
  • Injury data time period 1995-2001.2

About this data (continued)...
  • MSHA accident/illness classifications were used
    to categorize data.
  • Lost-time, non-fatal tire-related incidents were
    found in all of the following MSHA
  • Exploding Vessels Under Pressure
  • Hand Tools
  • Falling, Rolling, Sliding Rock or Material of
    Any Kind
  • Handling Material
  • Machinery
  • Powered Haulage, and
  • Other

In summary...
  • Multiple analyses of tire-related injury data are
    useful for determining which categories have the
    most lost days, highest accident frequencies, and
    for providing information on the types of
    injuries most likely to occur.
  • However, more detailed information about what
    REALLY happened is necessary to formulate useful
    safety interventions and effective training
