What Is Lockout Tagout?

People have always had a way of making hazardous energy work for them. Electrical, mechanical, hydraulic, pneumatic, chemical, or other energy sources can be hazardous to workers. During the maintenance or repair of the machinery, if it unexpected startup or release of stored energy, may result in serious injury or even death to workers.

To stop these from happening, energy isolation devices have been invented. It is a mechanical device that physically prevents the transmission or release of energy. These devices are usually valves, breakers, and switches.

Because these devices are dangerous, they are often locked up, using locks and tags as the second line of defense to protect workers’ lives. These locks and tags are also known as Lockout/Tagout (LOTO) and are mostly padlocks.

What kind of Lockout/Tagout is qualified?

As a Lockout/Tagout, it must do the following:

  1. Only employees authorized by the administrator are allowed to open the Lockout/Tagout
  2. It must be de-energized, this is to eliminate the risk of accidental release of dangerous energy, or lock failure due to power failure

Lockout/Tagout Recommendations

1. Passive electronic lock

Vanma Smart Lock is an electronic lock that does not require a power source. The smart key powers it, so it won’t fail due to power failure.

2. Authorization function

Vanma lockout/Tagout is an electronic lock that has authorization functions. The administrator grants permissions for specific employee keys in the system. And it can be precise to a specific date and time.

For energy isolation devices that require maintenance, the employee can schedule the maintenance date and submit a request to the administrator. He will issue permissions for the keys based on the requested schedule. In this way, the key will only be effective on the day of maintenance, preventing employees from unlocking the energy isolation device without permission.

3. Fingerprint key

Vanma Lockout/Tagout can opt fingerprint key. Workers are required to undergo fingerprint verification before unlocking. This prevents other employees from stealing the keys and opening energy isolation devices.

4. Lock or unlock records

Although the administrator can make authorization, the records are also important. Through the unlocking record, the administrator can know when the employee is locking or unlocking, which can also be used as evidence for tracing the responsibility.

Mechanical lock: Master Lock

The master lock has a full range of Lockout/Tagout, with different Lockout/Tagout types for cable and electrical, not just padlock. And you can choose different colors for the lockout to distinguish them visually. But the mechanical locks have some risks, such as employees copy keys, and unlocking the energy isolation device without permission. This does not serve as protection.
