What is the main goal for a lockout/tagout program?

The main goal of a lockout/tagout program is to protect workers from the unexpected release of hazardous energy while servicing equipment. By isolating and securing energy sources before work starts, LOTO prevents machines from starting up or discharging stored energy: a leading cause of serious maintenance injuries.

Ensure Power is Not Restored

When someone is working in or around heavily machinery that could cause them harm, it is not enough to simply shut it off. A machine that is turned off can easily be turned back on by someone who doesn’t realize that there is someone working on it. In addition, if there is a power surge of some type, it could cause the machine to energize and cause serious danger for the employee.

When the LOTO program is followed, it is physically impossible to restore the power to the machine or to have a surge deliver power to it. This allows the workers to complete the tasks that they are responsible for without having to worry about the risk of a machine turning on while they are there.

Preventing Accidents

Since only the person or people working on or around the machinery will have the ability to remove the lockout device from the power source, there is no way that this can happen unintentionally. This strategy was developed because it provides assurances that the person performing the work physically can’t still be in a hazardous area when they restore the power.

Proven Effective

OSHA first began mandating lockout/tagout practices in 1989 under regulation CFR 1910.147. They estimate that hundreds of fatalities each year could have been prevented prior to this point of employers had made similar programs mandatory.

Since this regulation was put in place, many lives have been saved and even more accidents prevented. While a LOTO program can result in a job taking additional time, the improved safety shows that it is well worth the effort.
