Help maintain workplace safety by using lockout tagout tags. Lockout Tagout (LOTO) safety tags are essential for wherever potential hazardous energy might occur around electrical, mechanical, hydraulic, chemical, thermal, or pneumatic machinery equipment is located. Help protect workers who routinely service machines by using a lockout tagout tag. National Marker Company provides LOTO solutions with lockout tags that come packaged in packs of 10, 25, 100, 150, or 150, with options available in either vinyl, synthetic paper or card stock. Masterman's provides additional LOTO safety with our selection of lockout devices, lockout kits and lockout stations.
