30 CFR 77.309-1 - Control Stations; Location..pdf

Mine Safety and Health Administration regulations for thermal dryers and mechanical equipment in coal mines include requirements for explosion release vents, access to drying chambers, fire protection, location and installation, control stations, alarm devices, and fail-safe monitoring systems. Thermal dryers must be located at least 100 feet from underground mine openings and surface installations, and be protected by explosion release vents and fireproof structures. Control stations must be installed in a location with a wide field of visibility, and control panels must be located in a dry and dust-free area with minimal vibration. Alarm devices must be equipped to operate when safe dryer temperatures are exceeded, and fail-safe monitoring systems must safely shut down the system upon component failure. Mechanical equipment must be guarded to prevent injury, including gears, sprockets, chains, and conveyor pulleys. Stationary grinding machines must be equipped with peripheral hoods, adjustable tool rests, and safety washers, and grinding wheels must be operated within manufacturer specifications. Face shields or goggles must be worn when operating a grinding wheel. Regular inspections and maintenance are required to ensure compliance with these regulations.
