What is the purpose of Lockout/Tagout (LOTO) procedures?

• A. To prevent unexpected energy release during maintenance or repair work
• B. To control access to work areas
• C. To manage inventory of tools
• D. To permit use of personal devices during work

Answer: (A)

Lockout/Tagout procedures are about keeping workers safe by making sure machines can’t start up or release stored energy while they’re being serviced. When equipment is being repaired or maintained, energy from sources like electricity, hydraulics, pneumatics, steam, or even gravity can suddenly surge or release stored energy, which can cause serious injuries. LOTO uses physical locks to keep energy sources isolated and tagged warnings to prevent re-energizing until the work is finished and it’s confirmed the area is safe. This approach reduces the risk of electrocution, crushing injuries, or unexpected machine movements during maintenance. It isn’t primarily about controlling access to areas, managing tool inventories, or permitting personal devices, which are separate safety or policy concerns.
