DEPARTMENT OF LABOR
Mine Safety and Health Administration
30 CFR Parts 56, 57, and 77
Safety Standards for Surface Haulage
AGENCY: Mine Safety and Health Administration (MSHA), Labor.
ACTION: Advance notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: MSHA is considering rulemaking to address factors believed to
cause or contribute to the occurrence or severity of surface haulage
accidents. Surface haulage equipment accidents are a leading safety
concern in the mining industry. MSHA is sharing its ideas and seeking
suggestions to reduce these accidents.
DATES: Submit comments and requests for meetings on or before August
31, 1998.
ADDRESSES: A copy of this notice may be obtained from the Office of
Standards, Regulations and Variances, Mine Safety and Health
Administration, 4015 Wilson Boulevard, Room 627, Arlington, Virginia
22203 and from any MSHA district office. Send mail comments to MSHA,
Office of Standards, Regulations, and Variances, at the above address.
Commenters are encouraged to submit comments on a computer disk along
with an original hard copy. Send comments by electronic mail to
comments@msha.gov or by facsimile to 703-235-5551.
FOR FURTHER INFORMATION CONTACT: Patricia W. Silvey, Director; MSHA,
Office of Standards, Regulations, and Variances; 703-235-1910.
SUPPLEMENTARY INFORMATION:
I. Background
Thirty percent of fatal mining accidents at surface mines and
surface areas of underground mines over the past three years involved
surface haulage equipment. Further, this equipment was cited as the
primary cause in 40 percent of the fatalities last year in the metal
and nonmetal mining industry.
MSHA examined approximately 8,000 surface accidents (from 1987 to
1996) involving powered haulage equipment which resulted in either
fatalities or lost work days. During that time, 120 miners were killed
and 1,377 were injured due to three causes or contributing factors:
unused or inadequate occupant restraint systems on the equipment; blind
areas on self-propelled mobile equipment; and lack of adequate
illumination.
II. Discussion of the Contributing Factors
Restraint Systems
The Agency is considering a requirement for all vehicles to have
restraint systems for the lower torso (seat belts) for both equipment
operators and passengers, whether or not the vehicle has Roll Over
Protective Structures (ROPS).
For newly manufactured equipment, except for on-highway trucks, the
Agency is considering requiring upper torso restraint systems (e.g.,
harnesses or equivalent) and an interlock system to prevent movement of
the vehicle unless the equipment operator's restraint system is
engaged. As an added safety feature, a light on the cab exterior could
indicate when the equipment operator's restraint system is engaged. The
Agency is also considering whether to extend the metal/nonmetal
requirement that grader operators wear safety lines and a harness when
operating the grader from a standing position to coal mines, instead of
a restraint system with interlock.
Issues to be considered include (1) requiring use of an interlock
system together with a mandated seat belt rule; (2) whether it is safe
to use restraint systems on vehicles not equipped with ROPS; (3)
whether there is a need to require restraint systems for passenger
seats; and (4) whether upper torso restraints would result in more neck
injuries. Specific examples, including documented evidence, if
available, would be useful.
Illumination
Illumination deficiencies contributed to a number of surface
haulage accidents because of problems associated with inability to see
victims, judge distances, clearly see berms and slope edges, and
restricted vision during inclement weather such as fog.
MSHA is considering the following requirements for illumination:
Permanently mounted lighting for pre-operational
examination of equipment;
Automatic backup lights that illuminate the rear-tire-to-
ground contact area;
Ground surface lighting for certain excavating equipment
operating in areas with uneven or irregular surfaces;
Lighting necessary to see the road ahead and objects in
blind areas; and
For off-highway equipment only, lighting on steps and hand
grip areas used to get in and out of the operator's compartment, and to
illuminate the ground area at the base of the steps.
Blind Areas
Surface haulage equipment involved in most fatal accidents include
rear dump trucks and articulated front-end loaders; they are also the
most used. The Agency is considering that this surface haulage
equipment should: (1) Have a system, such as video cameras, to enable
the operator to see blind areas; (2) have an automatic sensor to detect
objects or people in the blind area; (3) have a signal to alert people
that they are in blind areas; and (4) provide a signal to the operator
when objects or people have been sensed. The sensor could use infrared,
radio frequency, Doppler radar, or equivalent technology, so long as it
emits a signal. In order to be effective, object sensors would have to
automatically activate a viewing device (such as a video camera) and
monitor when an object is sensed. When a spotter is used to assist a
rear dump truck operator, two-way electronic communication between the
spotter and the operator is necessary for adequate protection.
MSHA is considering a performance approach where mine operators
would be required to eliminate left, right, and front blind areas on
all rear dump trucks and articulated front-end loaders. The Agency is
considering a requirement that all blind areas, including the rear,
must be eliminated on off-highway rear dump trucks and articulated
front-end loaders.
To enhance the visibility of smaller vehicles, such as service
trucks, pick-ups, and other vehicles that may operate in close
proximity to large surface haulage equipment, MSHA is considering a
requirement for flashing lights and pole or antenna-mounted flags on
these vehicles. Experience has shown that these smaller vehicles are
often obscured from the field of view of operators of larger equipment.
