When should Lockout/Tagout be used to protect workers?

• A. Before servicing equipment where unexpected energization could occur
• B. After starting equipment
• C. Only during maintenance on weekends
• D. Only for non-electrical tasks

Answer: (A)

Lockout/Tagout is used to keep workers safe by preventing equipment from energizing or releasing stored energy during maintenance or service. You apply the lock or tag to the energy source before you start any work that could be endangered by the machine starting up or by stored energy being released. This protection is necessary for all kinds of energy—electrical, hydraulic, pneumatic, mechanical—any time there’s a risk of unexpected energization. It’s about preventing harm by ensuring the equipment stays off while work is being done, not after it has already started.
