The U.S. Department of Labor’s Mine Safety and Health Administration introduced a new compliance assistance resource to address one of the most commonly cited violations in the metal and nonmetal mining industry: improperly guarded machinery.
“Guarding Machinery at Metal & Nonmetal Mines” is a sequel to a compliance guide for guarding conveyor belts published in 2010. In that year, guarding-related violations peaked at 10,877 and accounted for one of every seven violationscited.
“The purpose of this new guide designed to improve mine safety is threefold: to improve the mining industry’s understanding of good guarding principles; ensure the construction, installation and maintenance of high-quality, effective guards; and improve compliance, inspection and enforcement consistency,” said Assistant Secretary of Labor for Mine Safety and Health Joseph A. Main.
According to Parts 56/57.14107 of 30 Code of Federal Regulations, moving machine parts must be guarded to protect individuals 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. Guards are not required when the exposed moving parts are at least 7 ft. away from walking or working surfaces.
Injuries related to equipment guarding typically occur because guards are missing, inadequately sized or positioned, and also may be due to miners handling ordropping heavy, unwieldy and other poorly designed, constructed or maintained guards. For example, in some cases, lacerations or other injuries may occur due to a guard’s construction.
The new guide provides examples of good guarding practice and compliance information relating to all types of mining equipment, including drive and power transmission components; crushers and screens; rotating, packaging and palletizing equipment; power tools and auxiliary equipment.
