Safety and ComplianceSC-5EnglishSafety and Compliance Manual806690 Revision 7 – April 2020EnglishSafetyWARNING!Failure to follow operating instructions could result in personal injury or damage to equipment.RECOGNIZE SAFETY INFORMATIONDANGER WARNING CAUTIONAmerican National Standards Institute (ANSI) guidelines are used for safety signal words and symbols. The signal word DANGER or WARNING is used with a safety symbol. DANGER identifies the most serious hazards.• DANGER and WARNING safety labels are located on your machine near specific hazards.• DANGER safety messages precede related instructions in the manual that will result in serious injury or death if not followed correctly.• WARNING safety messages precede related instructions in this manual that may result in injury or death if not followed correctly.• CAUTION safety messages precede related instructions in this manual that may result in minor injury or damage to equipment if not followed correctly.INSPECT EQUIPMENT BEFORE USINGAll cutting equipment must be inspected as required to make sure it is in safe operating condition. When found to be incapable of reliable and safe operation, the equipment must be repaired by qualified personnel prior to its next use or withdrawn from service.The symbols shown in this section are used to identify potential hazards. When you see a safety symbol in this manual or on your machine, understand the potential for personal injury, and follow the related instructions to avoid the hazard.FOLLOW SAFETY INSTRUCTIONSCarefully read all safety messages in this manual and safety labels on your machine.• Keep the safety labels on your machine in good condition. Replace missing or damaged labels immediately.• Learn how to operate the machine and how to use the controls properly. Do not let anyone operate it without instruction.• Keep your machine in proper working condition. Unauthorized modifications to the machine may affect safety and machine service life.
SC-6Safety and ComplianceEnglishSafetyRESPONSIBILITY FOR SAFETYThe person or entity responsible for the safety of the workplace must:• Make sure that operators and their supervisors are trained in the safe use of their equipment, the safe use of the process, and emergency procedures.• Make sure that all hazards and safety precautions identified herein are communicated to and understood by workers before the start of work.• Designate approved cutting areas and establish procedures for safe cutting.• Be responsible for authorizing cutting operations in areas not specifically designed or approved for such processes.• Make sure that only approved equipment, such as torches and personal protective equipment, are used.• Select contractors who provide trained and qualified personnel, and who have awareness of the risks involved, to do cutting.• Tell contractors about flammable materials or hazardous conditions that are specific to the site, or hazardous conditions that they may not be aware of.• Make sure that the quality and quantity of air for ventilation is such that personnel exposures to hazardous contaminants are below the allowable limits.• Make sure that ventilation in confined spaces is sufficient to allow adequate oxygen for life support, to prevent accumulation of asphixiants or flammable explosive mixtures, to prevent oxygen-enriched atmospheres, and to keep airborne contaminants in breathing atmospheres below allowable limits.A PLASMA ARC CAN DAMAGE FROZEN PIPESFrozen pipes may be damaged or can burst if you attempt to thaw them with a plasma torch.STATIC ELECTRICITY CAN DAMAGE PRINTED CIRCUIT BOARDSUse proper precautions when handling printed circuit boards:• Store printed circuit boards in anti-static containers.• Wear a grounded wrist strap when handling printed circuit boards.GROUNDING SAFETYWork leadAttach the work lead securely to the workpiece or the cutting table with good metal-to-metal contact. Do not connect it to the piece that will fall away when the cut is complete.Cutting tableConnect the cutting table to an earth ground, in accordance with appropriate national and local electrical regulations.Input power• Make sure to connect the power cord ground wire to the ground in the disconnect box.• If installation of the plasma system involves connecting the power cord to the power supply, make sure to connect the power cord ground wire properly.• Place the power cord’s ground wire on the stud first, then place any other ground wires on top of the power cord ground. Tighten the retaining nut.• Tighten all electrical connections to avoid excessive heating.ELECTRICAL HAZARDS• Only trained and authorized personnel may open this equipment.• If the equipment is permanently connected, turn it off, and lock out/tag out power before the enclosure is opened.• If power is supplied to the equipment with a cord, unplug the unit before the enclosure is opened.• Lockable disconnects or lockable plug covers must be provided by others.• Wait 5 minutes after removal of power before entering the enclosure to allow stored energy to discharge.• If the equipment must have power when the enclosure is open for servicing, arc flash explosion hazards may exist. Follow all local requirements (NFPA 70E in the USA) for safe work practices and for personal protective equipment when servicing energized equipment.• Prior to operating the equipment after moving, opening, or servicing, make sure to close the enclosure and make sure that there is proper earth ground continuity to the enclosure.• Always follow these instructions for disconnecting power before inspecting or changing torch consumable parts.
