Abstract

Lockout tagout assemblies, systems, and methods are disclosed. Exemplary lockout tagout assemblies include a base, an arm moveable with respect to the base, and a member extending at an angle from the arm. The member can engage with a circuit breaker in an off position to retain the circuit breaker in the off position.

First claim

What is claimed is:

1. A system comprising a lockout tagout assembly, the system comprising:
a housing;
an electrical panel at least partially encased by the housing, the electrical panel comprising one or more circuit breakers, wherein each of the one or more circuit breakers includes a lever to switch the circuit breaker from an off position to an on position; and
a lockout tagout assembly, wherein the lockout tagout assembly comprises:
a base, wherein the base comprises an opening;
an arm moveable with respect to the base, wherein the arm comprises a first end and an opposing second end, wherein the first end is received by the base through the opening, and wherein the arm is configured to translate along a direction of the arm from a first position to a second position; and
a member extending at an angle from the second end of the arm,
wherein when the arm is in the first position, the member is received by a portion of an electrical panel to engage a circuit breaker in an off position,
wherein when the arm is in the second position, the member is not engaged with the circuit breaker, and
wherein at least a portion of the arm is received within the base through the opening, and wherein a greater portion of the arm is received within the base through the opening when the arm is in the second position than when the arm is in the first position.

2. The system of claim 1 , further comprising a first magnet to retain the arm in the second position when the member is not engaged with the circuit breaker.

3. The system of claim 1 , further comprising a retaining device to retain the arm in the first position.

4. The system of claim 3 , wherein the retaining device comprises one or more of a wire and a pin.

5. The system of claim 1 , wherein the member is fixedly attached to the arm.

6. The system of claim 2 , further comprising a second magnet disposed in the base such that the second magnet only contacts the first magnet when in the second position, wherein the first magnet is disposed on the first end of the arm.

7. The system of claim 1 , comprising a plurality of arms received by the base.

8. The system of claim 7 , wherein each arm of the plurality of arms moves independently relative to the base.

9. The system of claim 7 , wherein a single retaining device retains two or more of the plurality of arms in the first position.

10. The system of claim 1 , wherein the angle is between about 30 degrees and about 150 degrees, between about 60 degrees and about 120 degrees, or is about 90 degrees.

11. The system of claim 1 , wherein the arm comprises polyoxymethylene.

12. The system of claim 1 , wherein the member comprises polyoxymethylene.

13. The system of claim 1 , wherein the member and the arm comprise a unitary structure.

14. The system of claim 1 , wherein the base is coupled to the housing.

15. The system of claim 1 , wherein the system forms part of a reactor system.
