Lotomaster’s Caution Lockout Tags are made of flexible plastic which can be attached to all the lockout devices using a padlock or a cable tie. Tagout devices warn against hazardous conditions if the machine or equipment is energized. Additionally OSHA 1910.333(e) and (f) require that all disconnecting means show the magnitude and shall be legibly marked to indicate the purpose, unless located and arranged so the purpose is evident.
