The principle of "safety lockout"

All personnel into the equipment, close to the equipment maintenance operations must be dangerous parts to cut off the power supply equipment for safety lockout management, ensure the equipment in the closed state, to avoid the equipment by others wrong operation started, ensure the safety of operation personnel management principles.

The scope of "safety lockout"

1, the personnel to enter the power facilities within the space must be safety lockout;

2, electric power, electrical equipment maintenance must be safety lockout; 

3, power machinery, rotating equipment, transmission equipment maintenance must be safety lockout (including mill, crusher, blower, bucket, reamer, zipper machine, classifier, electric dust collector, hammer broken, plate feeding machine, belt conveyor, mining mobile devices, etc.); 


Energy isolation management requirements

The basic requirements

All isolation facilities for hazardous energy and materials shall be energy isolated, lockout and tagout and tested for isolation effect.

Each basic unit shall establish an energy isolation facility ledger, which shall specify the time and place for dismantling and adding personnel.

When the isolation point does not have the conditions for locking, the operator and the relevant person in charge of the territorial unit to agree and sign on the tag, can only hang the tag without locking.

Lock must tag

Safety locks must be and "dangerous!" Do not use the "operations"tag at the same time. The electrical operation shall follow the relevant national electrical operation rules.

Before commencing operations, it is the responsibility of both the territorial unit and the operator to ensure that isolation is in place and to implement lockout and tagout.

Lockout/Tagout Procedures: Who Can Cut Off a Lock

" Implementing these guidelines ensure that employees are safe and are up-to-date of what steps are being taken when these situations arise."

Who Can Cut Off a Lock and When

Imagine an EH&S manager who thinks he has good lockout/tagout procedures in place when the maintenance supervisor takes an unexpected leave of absence. The manager walks onto the floor and realizes one of the largest hydraulic presses isn’t running. Looking at the main electrical disconnect, he finds the unit has been locked out…by his maintenance manager. The department is already behind schedule and this press needs to be up & running now. What next? Does the manager remove the lock himself? Does he have no choice but to leave it until the employee returns? This article will explain the dos and don’ts when it comes to removing another employee’s lockout lock, who can cut off a lock, and how to handle this type of situation.

According to OSHA’s lockout/tagout regulation, 1910.147, “Each lockout or tagout device shall be removed from each energy-isolating device by the employee who applied the device.” The exception to this rule follows as, “When the authorized employee who applied the lockout or tagout device is not available to remove it, that device may be removed under the direction of the employer, provided that specific procedures and training for such removal have been developed, documented, and incorporated into the employer’s energy control program.”

In other words, under proper authorization of the employer, a supervisor may remove an employee’s lockout lock. This exception is only allowed under the circumstances that the employee who placed the lock is unavailable and it is absolutely necessary that the unit be returned to normal operation. When running into this situation, there are simple steps to be taken to ensure it is properly handled.

1The employer must verify that the authorized employee who originally placed the lockout device is nowhere in the facility.

2The employer must make all reasonable efforts to contact the authorized employee to inform them that their lockout device will be removed.

3The employer must inform the authorized employee that their lockout has been removed before they resume work at the facility.

4The employer or supervisor should ensure the machine is in working condition & capable of being turned back on, that all components and guarding are properly reinstalled from servicing, and no tools have been left in the area.

5 Provide a form to document what steps are being taken during the entire process, and to keep track of which responsibilities are being passed on to which employee.
