Safety padlocks and lockout tagout (LOTO) are safety measures used in workplaces to ensure that hazardous energy sources are isolated and locked out during maintenance, repair, and servicing activities. Safety padlocks are designed to prevent unauthorized access to locked-out equipment and machinery while lockout tagout procedures involve the use of tags and locks to identify and isolate energy sources. LOTO is a critical safety procedure in industries such as manufacturing, construction, and engineering, where workers are at risk of coming into contact with live electrical, mechanical, or pneumatic energy sources.

Safety lock usage principles include ensuring that all hazardous energy sources are properly identified, and that appropriate lockout procedures are in place before beginning maintenance, repair, or servicing activities. The padlocks and locks used in lockout tagout should be durable and tamper-proof, and only authorized personnel should have access to the keys. Before removing a lock that has been placed on a machine or equipment, workers should ensure that all energy sources have been safely isolated and that it is safe to perform the necessary work. Finally, regular training and assessment should be conducted to ensure that workers understand and comply with lockout tagout procedures to prevent accidents and injuries in the workplace.
