There are different hazardous energy sources for every industry. Each energy source needs to be lockout properly during maintenance or repairs to avoid workplace accidents. As the industry evolves, the need to maintain workplace safety has also changed. To date, the common types of lockout and tagout devices include padlocks, valve lockouts, breaker lockouts, plug lockouts, lock boxes, hasps, safety tags, and danger tags.
As technology advances every day, new lockout and tagout devices may be developed to accommodate the LOTO needs of various industrial workplaces.
