LOTOTO Basics
This three-part process is used when servicing or maintaining equipment and a danger zone may exist
What is LOTOTO?
These are potential energy sources
What is electrical, hydraulic, pneumatic, steam, thermal, chemical, gravity, vacuum, or mechanical energy?
The first verification/procedure step is to do this before shutting down equipment
What is inform all affected employees?
The BFG3 standard identifies this color as the LOTOTO lock.
What is red?
An employee who locks out or tags out equipment to perform servicing or maintenance is this type of employee
What is an authorized employee?
In LOTOTO, this action blocks the flow of energy from the power source so service can occur safely
What is lockout?
This energy source can remain in equipment because of elevated components or other stored potential
What is gravity?
After shutdown, this must be identified before energy sources are isolated.
What are all lockout points?
Each red lock must have one of these.
What is a personal tag?
An employee who operates or uses equipment while servicing is being performed under lockout/tagout is this type.
What is an affected employee?
This part of LOTOTO warns people nearby that equipment is being controlled and should not be operated
What is tagout?
Each time a lockout is performed, this BFG3 tag must be completed.
What is a PV1 card?
After applying locks and tags, this must be done before tryout
What is release all stored energy?
A tag alone is not considered a lockout device because it does not do this
What is prevent equipment start-up?
This type of lockout is used when several people must be involved in servicing or maintenance
What is group lockout?
This part of LOTOTO verifies that the energy source has actually been de-energized
What is tryout?
To perform tryout, attempt to restart the machine while leaving the controls in this position.
What is the off position?
Personal locks and tags shall indicate this about the employee applying them.
What is the employee's identity? Photo, name etc.
In group lockout, keys from the group locks are placed in this device.
What is the group lockbox?
LOTOTO may be required when an employee must place a body part into this area
What is the danger zone/the line of fire
Put these in the correct order: apply locks/tags; shut down; identify lockout points; inform affected employees
What is inform affected employees → shut down → identify lockout points → apply locks/tags?
Red LOTOTO locks MUST NOT be used for ordinary items such as these
What are toolboxes, lockers, bicycles, or other non-LOTOTO uses?
Each authorized employee does this after placing their personal lock and tag on the group lockbox
What is tryout?
