Which method is recommended to block mechanical energy during lockout?

Blocking mechanical energy during lockout is accomplished through methods designed to prevent any unintentional release of energy that could cause harm. Utilizing die blocks, restraining pins, bars, or blocks under rams is essential because these tools provide a physical barrier that secures equipment in a safe position, ensuring it cannot move or operate unexpectedly. This method effectively immobilizes machinery and protects workers from the risks associated with mechanical energy release.

While using safety cones is helpful for marking off hazardous areas, they do not prevent machinery from moving; they only serve as indicators. Simply turning off power switches may not be sufficient on its own, as it doesn't address other sources of energy, such as stored mechanical energy. Having someone supervise might help increase safety awareness, but it does not eliminate the risk of accidental movement or operation of equipment. Therefore, employing die blocks and similar mechanisms is the most effective method for safely blocking mechanical energy during a lockout situation.
