1. 56.14 107A Moving machine parts: (a). Moving machine parts shall be guarded to protect persons from contacting gears, sprockets, chains, drive, head, tail, and take-up pulleys, flywheels, couplings, shafts, fan blades, and similar moving parts that can cause injury. (b) Guards shall not be required where the exposed moving parts are at least seven feet away from walking or working surfaces. MSHA PPM - 56/57.14107 Moving Machine Parts: All moving parts identified under this standard are to be guarded with adequately constructed, installed and maintained guards to provide the required protection. The use of chains to rail off walkways and travel-ways near moving machine parts, with or without the posting of warning signs in lieu of guards, is not in compliance with this standard. Conveyor belt rollers are not to be construed as "similar exposed moving machine parts" under the standard and cannot be cited for the absence of guards and violation of this standard where skirt boards exist along the belt. However, inspectors should recognize the accident potential, bring the hazard to the attention of the mine operators, and recommend appropriate safeguards to prevent injuries. This standard is to be cited when a guard at conveyor locations does not extend a distance sufficient to prevent any parts of a person from accidentally getting behind the guard and becoming caught, or in those instances when there is no guard at the conveyor-drive, conveyor-head, conveyor-tail, or conveyor take-up pulleys.

2. 56.14 100B Safety defects; examination, correction and records: SAFETY DEVICES AND MAINTENANCE REQUIREMENTS (a) Self-propelled mobile equipment to be used during a shift shall be inspected by the equipment operator before being placed in operation on that shift. (b) Defects on any equipment, machinery, and tools that affect safety shall be corrected in a timely manner to prevent the creation of a hazard to persons. (c) When defects make continued operation hazardous to persons, the defective items including self-propelled mobile equipment shall be taken out of service and placed in a designated area posted for that purpose, or a tag or other effective method of marking the defective items shall be used to prohibit further use until the defects are corrected. (d) Defects on self-propelled mobile equipment affecting safety, which are not corrected immediately, shall be reported to and recorded by the mine operator. The records shall be kept at the mine or nearest mine office from the date the defects are recorded, until the defects are corrected. Such records shall be made available for inspection by an authorized representative of the Secretary. MSHA PPM - 56/57.14100 Safety Defects: Examination, Correction, and Records This standard applies to all off-road and on-road self-propelled equipment used on mine property, including vehicles such as vans, suburbans, and pick-up trucks that are used at mine sites and remain on mine property. In most instances, it does not apply to vehicles used to transport persons between locations off mine property to mine property; however, if such vehicles transport personnel on mine property (e.g., from the gate to various sites at the mine), then such equipment must be inspected. This standard will not be cited when an audible warning device has been installed on heavy duty mobile equipment at surface mines and surface operations of underground mines, but is inoperative because of electrical or mechanical defect. Standard .14132 shall be used when the equipment has not been equipped with audible warning devices, or when they have been so equipped, and the device is not operational for whatever reason. In some cases, mine operators have installed audible reverse alarms on underground equipment because prevailing conditions have dictated the need for a warning device to ensure miner safety. In this instance, Standard .14100 can be considered if the alarm is inoperable or inaudible and the defect can be shown to affect the safety of workers in the area. Surrounding noise levels, confined work areas, and distracting work assignments shall be considered at the time.

2. 56.14 132A Horns and backup alarms: (a). Manually-operated horns or other audible warning devices provided on self-propelled mobile equipment as a safety feature shall be maintained in functional condition. (b)(1) When the operator has an obstructed view to the rear, self-propelled mobile equipment shall have (b)(1)(i) An automatic reverse-activated signal alarm; (b)(1)(ii) A wheel-mounted bell alarm, which sounds at least once for each three feet of reverse movement; (b)(1)(iii) A discriminating backup alarm that covers the area of obstructed view; or (b)(1)(iv) An observer to signal when it is safe to back up. (b)(2) Alarms shall be audible above the surrounding noise level. (b)(3) An automatic reverse-activated strobe light may be used at night in lieu of an audible reverse alarm. (c) This standard does not apply to rail equipment.

3. 56.11 001 Safe access: Safe means of access shall be provided and maintained to all working places.

3. 56.20 003A Housekeeping at all mining operations: (a). Workplaces, passageways, storerooms, and service rooms shall be kept clean and orderly. (b) The floor of every workplace shall be maintained in a clean and, so far as possible, dry condition. Where wet processes are used, drainage shall be maintained, and false floors, platforms, mats, or other dry standing places shall be provided where practicable; and (c) Every floor, working place, and passageway shall be kept free from protruding nails, splinters, holes, or loose boards, as practicable.

4. 56.11 002 Handrails and toe-boards: Crossovers, elevated walkways, elevated ramps, and stairways shall be of substantial construction provided with handrails, and maintained in good condition. Where necessary, toe-boards shall be provided.

5. 56.14 101A2 Brakes: (a) Minimum requirements. (2) If equipped on self-propelled mobile equipment, parking brakes shall be capable of holding the equipment with its typical load on the maximum grade it travels. MSHA PPM - 56/57.14101(a) Brakes/Minimum Requirements Subsection (a) is divided into three parts. Part (1) of this subsection sets a minimum performance standard for service brake systems on self-propelled mobile equipment. Part (2) sets a minimum performance standard for parking brakes on self-propelled mobile equipment. Part (3) sets a maintenance standard for all braking systems on self-propelled mobile equipment. Standard 56/57.14101(a)(1) should be cited if a service brake system is not capable of stopping and holding the equipment with its typical load on the maximum grade it travels. Standard 56/57.14101(a)(2) should be cited if the parking brakes are not capable of holding the equipment with its typical load on the maximum grade it travels. Standard 56/57.14101(a)(3) should be cited if a component or portion of any braking system on the equipment is not maintained in functional condition even though the braking system is in compliance with (1) and/or (2) above. It is important to note that if a component or portion of either system renders the equipment incapable of stopping or holding itself with its typical load on the maximum grade it travels, the appropriate standard, 56/57.14101(a)(1) or (2), should be cited. Separate citations or orders should be issued if violations of 56/57.14101(a)(1) and 56/57.14101(a)(2) are found on the same piece of equipment.

6. 56.12 028 Testing grounding systems: Continuity and resistance of grounding systems shall be tested immediately after installation, repair, and modification; and annually thereafter. A record of the resistance measured during the most recent tests shall be made available on a request by the Secretary or his duly authorized representative.

MSHA PPM - 56/57.12028 Testing Grounding Systems: This intent of this standard is to ensure that continuity and resistance tests of grounding systems are conducted on a specific schedule. These tests will alert the mine operator if a problem exists in the grounding system which may not allow the circuit protective devices to quickly operate when faults occur. With the exception of fixed installations, numerous fatalities and injuries have occurred due to high resistance or lack of continuity in equipment ground systems. These accident could have been prevented by proper testing and maintenance of grounding systems. Grounding systems typically include the following: equipment grounding conductors - the conductors used to connect the metal frames or enclosures of electrical equipment to the grounding electrode conductor; grounding electrode conductor - the conductors connecting the grounding electrode to the equipment grounding conductor; and grounding electrodes - usually driven rods connected to each other by suitable means, buried metal, or other effective methods located at the source, to provide a low resistance earth connection. Operators shall conduct the following tests: Equipment grounding conductors - continuity and resistance must be tested immediately after installation, repair, or modification, and annually if conductors are subjected to vibration, flexing or corrosive environments; Grounding electrode conductor - continuity and resistance must be tested immediately after installation, repair, or modification, and annually if conductors are subjected to vibration, flexing or corrosive environments; and Grounding electrodes - resistance must be tested immediately after installation, repair, or modification, and annually thereafter. Conductors in fixed installations, such as rigid conduit, armored cable, raceways, cable trays, etc., that are not subjected to vibrations, flexing or corrosive environments may be examined annually by visual observation to check for damage in lieu of the annual resistance test. When operators elect to conduct this visual examination as a method of compliance with 30 CFR 56/57.12028, MSHA will require that a record be maintained of the most recent annual visual examination. The grounding conductors in trailing cables, power cables, and cords that supply power to tools and portable or mobile equipment must be tested as prescribed in the regulation. This requirement does not apply to double-insulated tools or circuits protected by ground-fault-circuit interrupters that trip a 5 milli-amperes or less. Testing of equipment grounding conductors and grounding electrode conductors is not required if a fail-safe ground wire monitor is used to continuously monitor the grounding circuit and which will cause the circuit protective devices to operate when the grounding conductor continuity is broken. A record of the most recent resistance tests conducted must be kept and made available to the Secretary or his authorized representative upon request. When a record of testing is required by the standard, MSHA intends that the test results be recorded in resistance value in ohms.

7. 56.4 201A2 Inspection of fire-fighting equipment: (a) Firefighting equipment shall be inspected according to the following schedules: (1) Fire extinguishers shall be inspected visually at least once a month to determine that they are fully charged and operable. (2) At least once every twelve months, maintenance checks shall be made of mechanical parts, the amount and condition of extinguishing agent and expellant, and the condition of the hose, nozzle, and vessel to determine that the fire extinguishers will operate effectively. (3) Fire extinguishers shall be hydrostatically tested according to Table C-1 or a schedule based on the manufacturer's specifications to determine the integrity of extinguishing agent vessels. (4) Water pipes, valves, outlets, hydrants, and hoses that are part of the mine's firefighting system shall be visually inspected at least once every three months for damage or deterioration and use-tested at least once every twelve months to determine that they remain functional. (5) Fire suppression systems shall be inspected at least once every twelve months. An inspection schedule based on the manufacturer's specifications or the equivalent shall be established for individual components of a system and followed to determine that the system remains functional. Surface fire suppression systems are exempt from these inspection requirements if the systems are used solely for the protection of property and no persons would be affected by a fire. (b) At the completion of each inspection or test required by this standard, the person making the inspection or test shall certify that the inspection or test has been made and the date on which it was made. Certifications of hydrostatic testing shall be retained until the fire extinguisher is retested or permanently removed from service. Other certifications shall be retained for one year.

Table C-1 Hydrostatic Test Intervals for Fire Extinguishers

(g) Wearing seat belts. Seat belts shall be worn by the equipment operator except that when operating graders from a standing position, the grader operator shall wear safety lines and a harness in place of a seat belt. (h) Seat belts construction. Seat belts shall meet the requirements of SAE J386, "Operator Restraint Systems for Off-Road Work Machines", 1985; or SAE J1194, "Roll-Over Protective Structures (ROPS) For Wheeled Agricultural Tractors", 1983, as applicable, which are incorporated by reference. (i) Seat belt maintenance. Seat belts shall be maintained in functional condition, and replaced when necessary to assure proper performance. (j) Publications. Publications incorporated by reference in this section have been approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a). Copies are available from the Administrator for Metal and Nonmetal Mine Safety and Health, MSHA, 4015 Wilson Blvd., Arlington, Virginia 22203, and may be examined at any Metal and Nonmetal District Office. Copies may also be obtained from the Society of Automotive Engineers, 400 Commonwealth Drive, Warrendale, PA 15096. MSHA PPM - 56/57.14130 and 56/57.14131 Providing, Maintaining, and Wearing Seat Belts: In an effort to reduce the severity of powered haulage accidents, district managers shall carefully consider the gravity and negligence of citations and orders issued for the failure to provide, maintain, or wear seat belts. Gravity: The failure to provide, maintain, or wear seat belts is a serious safety hazard and under most circumstances should be a significant and substantial violation. Without mitigating circumstances, the gravity evaluation of reasonably likely or highly likely, and fatal would usually be justified. Negligence: The failure to provide seat belts as required by the regulations may be considered highly negligent and therefore be the basis for a 104(d) citation/order in the absence of mitigating circumstances. Failure to maintain seat belts in functional condition may be considered less negligent than the failure to provide seat belts. Some factors that could increase the degree of negligence are if the defect has been reported on a pre-shift examination, the defect is obvious, or the defect has existed for a long period of time. The examination of seat belts for defects is required by 30 CFR 56/57.14100. Negligence for failure to wear seat belts should be determined by the extent of the mine operator's efforts to enforce the seat belt requirement. Examples of such efforts may include: 1. Evidence that the equipment operators are instructed on the mandatory use of seat belts; 2. Regular observation by supervisors to determine whether seat belts are being worn; 3. Corrective action taken by supervisors when seat belts are not being worn; and 4. The development and implementation of a job safety analysis program to reinforce task training for equipment operators. If the mine operator does not make any effort to ensure that seat belts are worn, the negligence would be high and a 104(d) citation/order would be appropriate. If, however, the mine operator's conduct indicated an effort to have seat belts worn, the negligence would usually be less than high. Special Assessment: All citations/orders issued for failure to provide, maintain, or wear seat belts should be reviewed for special assessment. The types of violations that meet the requirements for special assessments are: 1. Violations cited as contributing to a serious injury or fatality; 2. Violations cited as an unwarrantable failure; 3. Violations cited as an imminent danger; or 4. Violations evaluated as having extraordinarily high gravity (highly likely and fatal).

10. 56.15 001 First-aid materials: Adequate first-aid materials, including stretchers and blankets, shall be provided at places convenient to all working areas. Water or neutralizing agents shall be available where corrosive chemicals or other harmful substances are stored, handled, or used. MSHA PPM - 56/57.15001 First Aid Materials. This standard requires that adequate first-aid materials, including stretchers and blankets, shall be provided at places convenient to all working areas, and that water or neutralizing agents shall be available where corrosive chemicals or other harmful substances are stored, handled or used. The purpose of this mandatory standard is to ensure that adequate first-aid materials, including eye wash solution, safety showers (not just "deluge" showers, but a constant warm water supply for long-term flushing) and other neutralizing agents are available to workers where corrosive chemicals or other harmful substances are stored, handled, or used. Neutralizing agents shall be readily available for first-aid treatment and cleanup of corrosive chemical spillage or leakage. Spill-control products are commercially available for all hazardous chemical substances. These products both absorb and neutralize hazardous chemicals, thereby reducing the hazard to workers while containing the spilled chemicals

11. 56.1 000 Notification of commencement of operations and closing of mines. PROCEDURES: The owner, operator, or person in charge of any metal and nonmetal mine shall notify the nearest Mine Safety and Health Administration and Metal and Nonmetal Mine Safety and Health District Office before starting operations, of the approximate or actual date mine operation will commence. The notification shall include the mine name, location, the company name, mailing address, person in charge, and whether operations will be continuous or intermittent. When any mine is closed, the person in charge shall notify the nearest district office as provided above and indicate whether the closure is temporary or permanent.

11. 56.12 025 Grounding circuit enclosures: All metal enclosing or encasing electrical circuits shall be grounded or provided with equivalent protection. This requirement does not apply to battery-operated equipment.

11. 56.18 002A Examination of working places. (a) A competent person designated by the operator shall examine each working place at least once each shift for conditions which may adversely affect safety or health. The operator shall promptly initiate appropriate action to correct such conditions. (b) A record that such examinations were conducted shall be kept by the operator for a period of one year, and shall be made available for review by the Secretary or his authorized representative. (c) In addition, conditions that may present an imminent danger which are noted by the person conducting the examination shall be brought to the immediate attention of the operator who shall withdraw all persons from the area affected (except persons referred to in section 104(c) of the Federal Mine Safety and Health Act of 1977) until the danger is abated. MSHA PPM - 56/57.18002 Examination of Working Place 30 CFR §§ 56/57.18002, Examination of working places, provide: 1. A competent person designated by the operator shall examine each working place at least once each shift for conditions, which may adversely affect safety or health. The operator shall promptly initiate appropriate action to correct such conditions. 2. A record that such examinations were conducted shall be kept by the operator for a period of one year, and shall be made available for review by the Secretary or his authorized representative. 3. In addition, conditions that may present an imminent danger which are noted by the person conducting the examination shall be brought to the immediate attention of the operator who shall withdraw all persons from the area affected (except persons referred to in section 104(c) of the Federal Mine Safety and Health Act of 1977) until the danger is abated. MSHA intends that the terms "competent person" and "working place," used in §§ 56/57.18002(a), be interpreted as defined in §§ 56/57.2, Definitions. A "competent person," according to §§ 56/57.2, is "a person having abilities and experience that fully qualify him to perform the duty to which he is assigned." This definition includes any person who, in the judgment of the operator, is fully qualified to perform the assigned task. MSHA does not require that a competent person be a mine foreman, mine superintendent, or other person associated with mine management. The phrase "working place" is defined in 30 CFR §§ 56/57.2 as: "any place in or about a mine where work is being performed." As used in the standard, the phrase applies to those locations at a mine site where persons work during a shift in the mining or milling processes. Standards 56/57.18002(b) require operators to keep records of working place examinations. These records must include: (1) the date the examination was made; (2) the examiner's name; and (3) the working places examined. MSHA intends to allow operators considerable flexibility in complying with this provision in order to minimize the paperwork burden. Records of examinations may be entered on computer data bases or documents already in use, such as production sheets, logs, charts, time cards, or other format that is more convenient for mine operators. In order to comply with the record retention portion of §§ 56/57.18002(b), operators must retain workplace examination records for the preceding 12 months. As an alternative to the 12-month retention period, an operator may discard these records after MSHA has completed its next regular inspection of the mine, if the operator also certifies that the examinations have been made for the preceding 12 months. Evidence that a previous shift examination was not conducted or that prompt corrective action was not taken will result in a citation for violation of §§ 56/57.18002(a) or (c). This evidence may include information, which demonstrates that safety or health hazards existed prior to the working shift in which they were found. Although the presence of hazards covered by other standards may indicate a failure to comply with this standard, MSHA does not intend to cite §§ 56/57.18002 automatically when the Agency finds an imminent danger or a violation of another standard.
