Common Safety Lockout Questions

What is lockout / tagout?

LOTO is the physical restraint of all hazardous energy sources that supply power to a piece of equipment, machinery or system. LOTO also includes applying a warning tag on the physical restraint device. This documents the authorized LOTO personnel and the date. LOTO operations must be done on all equipment, machinery or system shut downs before authorized personnel can perform repairs or service.

Most equipment and machinery has an energy isolation device. These devices are usually put into the off position to shut down the hazardous energy source. Physical restraints (Lock Out Devices) can be put onto the energy isolation device and secured with padlocks. Examples of Lock Out Devices include: ball valve and gate valve lock outs, circuit breaker lockouts, plug and wall switch lock outs and pneumatic lock outs. The total shutdown and restraint of all hazardous energy sources including the safe release of stored hazardous energy (e.g. capacitors and pressure in a line) must be accounted for.

What is the OSHA standard for Lockout/Tagout?

The OSHA standard for The Control of Hazardous Energy (Lockout/Tagout), Title 29 Code of Federal Regulations (CFR) Part 1910.147, addresses the practices and procedures necessary to disable machinery or equipment, thereby preventing the release of hazardous energy while employees perform servicing and maintenance activities.

When does Lockout/Tagout apply?

Lockout/Tagout applies whenever the employee performs service or maintenance on equipment/machinery that requires the employee to remove or bypass a guard or safety device or requires the employee to place any part of his/her body at the point of operation of the equipment/machinery.

What is hazardous energy?

Energy sources including electrical, mechanical, hydraulic, pneumatic, chemical, thermal or other sources in machines and equipment can be hazardous to workers. During the servicing and maintenance of machines and equipment, the unexpected startup or release of stored energy could cause injury to employees.

What is group lockout?

When two or more employees or subcontractors are working on different parts of a larger overall system, each employee or subcontractor applies their own padlock to a group lockout device. The locked out system cannot be activated until all workers have signed off on their portion of the project and removed their padlock from the safety lockout device.


Shipping Questions

How soon will my order ship?

We try to stock as many items as we can, however, many of the products that are keyed alike or master keyed require custom manufacturing and will have a lead time before shipping, especially items that are being custom matched to an existing key number.
