Why Do We Need to Lock/Tag?

Nov. 11, 2020

According to OSHA (Occupational Health and Safety Administration), if the lockout/tagout is not implemented properly, approximately 3 million U.S. service equipment workers are at the greatest risk of injury. Locking/listing in the United States alone can prevent an estimated 120 facilities and 60,000 injuries from being injured each year. The safety padlock manufacturer shares this article with you.

According to OSHA regulations: "Every employer shall provide every employee with employment and a place of work. These jobs and places of work shall be protected from recognized hazards that can cause or may result in death or serious personal injury."

The valve locking/hanging out standard is a necessary clause because it can prevent physical hazards that may cause serious consequences due to the powerful power of certain machines. Complying with OSHA's "lockout/listing program" not only protects employers from illegal citations but more importantly, it protects employees from serious personal injury.

Who can perform the lock?

The standard allows each employer to flexibly formulate an energy control plan suitable for a specific workplace and the equipment used, maintained and maintained. The plan aims to cover three types of employees:

Authorized employees: Employees who lock or mark machines and equipment for repair or maintenance.

Affected employees: employees in areas where they are required to lock or mark machines or equipment for authorized personnel to perform repairs or maintenance on the machines or equipment.

Other employees: All employees in areas where energy control procedures are or may be used must accept instructions on energy control procedures. Employees need to be instructed to strictly prohibit removing locked or tag equipment and then try to restart, re-energize or operate the machine.

In addition to protecting employees, shutdown/listing standards can also help cut costs and increase productivity, reduce accidents, reduce and reduce indirect costs and costs caused by shutdown/listing injuries, and reduce equipment downtime.

The sequence of the process of locking or registering the system

  • Notify all affected employees that they will use lockout or lockout tagout and why. Authorized employees should understand the type and amount of energy used by the machine or equipment, and should understand its hazards.

  • If the machine is running, please turn it off according to the normal stopping procedure (press the stop button, turn on the toggle switch, etc.).

  • Operate switching valves or other energy isolation equipment to isolate the equipment from its energy source. The stored energy (such as springs, overhead mechanical components, rotating flywheels, hydraulic systems, and air, gas, steam or water pressure, etc.) must be dissipated or restrained by repositioning, blocking, venting, etc. .

  • Ensure that no people are exposed, and after checking whether the power connection has been disconnected, please operate buttons or other normal operation controls to ensure that the device will not work.

  • The device is now locked or marked.

Lockout/Listing Procedure

OSHA 1910.147(d) requires the control of hazardous energy in accordance with a six-step procedure

  • Prepare for shutdown

  • Shut down the device

  • Isolate all energy

  • Application of locks and tags

  • Release stored energy

  • Equipment isolation verification
