Lockout/Tagout then TRY OUT.

Energy sources in machines and equipment can be extremely hazardous to workers. During the servicing and maintenance of machine and equipment, the unexpected start-up or release of stored energy can result in serious injury or death.

According to OSHA, failure to control hazardous energy accounts for nearly 10 percent of the serious accidents in many industries. Proper Lockout/Tagout (LOTO) practices and procedures safeguard workers from hazardous energy releases.Do Not Operate Equipment LockOut/Tagout

In the United States, the applicable OSHA standard is the Control of Hazardous Energy (Lockout/Tagout)29 CFR 1910.147
In Canada, the applicable CSA standard is the Control of Hazardous Energy – Lockout And Other Methods Z460-13.

At Belt Conveyor Guarding we feel equipment is not adequately Locked Out and Tagged Out until it has been TRIED OUT (LOTOTO).

 A worker must:

  1. Stop the equipment, disconnect power and lock the switch;
  2. Attach their identifying tag;
  3. After ensuring workers are clear, try to start the equipment to test if energy sources have been disconnected.

Following these steps ensures all energy sources are isolated before electrical or mechanical work is performed. The process protects workers from the dangers of uncontrolled, unplanned release of energy.

When should you LockOut/TagOut?

  • When removing or bypassing a guard or other safety device for maintenance, repair, cleaning or clearing jammed mechanisms.
  • When placing any part of one’s body where it could be injured by moving machinery parts or release of stored energy (hydraulic or pneumatic pressure, steam, spring, objects that could fall or pivot).
  • When placing any part of one’s body into electrical energy or hazardous substance danger zones.

It is imperative that machinery is properly locked out, tagged out and has been tried out BEFORE removing safety guards. All workers should be properly trained on compliant lockout procedures to ensure a close call doesn’t turn into a fatal encounter.

Your Stories:

A 33-year-old maintenance worker was attempting to restore power supply to a conveyor belt motor. The worker used a lockout system to power off the line; the worker was tasked with splicing the power wires to make the proper connections to the conveyor motor. When the worker attempted to splice the wire, the wire was in fact still live and the worker was electrocuted causing a fatal cardiac arrest.

During the investigation, it was determined the lockout system was affixed to the wrong circuit breaker.

We implore you to please follow the LockOut/TagOut &Try Out (LOTOTO) procedure. It could save you or a co-worker’s life.
