It is the policy of the CSP to comply with this procedure to the fullest extent.
Lockout / Tagout Procedure
4a
Process of preventing the flow of energy◦ Consists of installing a lock, block, or chain◦ Requires an Authorized Employee to
apply/remove lock
Lockout definition
2a
Process of placing a warning tag on the energy source◦ The tag acts as a warning◦ The tag must clearly state “Do not operate”◦ The tag can be used when the machine won’t
accept lock◦ The tag must be applied/removed by an
Authorized Employee
Tagout definition
2b
Authorized employee: A person who locks out or tags out machines
before the servicing or maintenance of equipment can proceed.
Affected employee: An employee who will do work on the equipment An employee who works in the area Cannot help authorized employees service
machinery Can be considered an authorized employee
Employee Role definition
1b
The energy sources can take several forms: ◦ Electrical◦ Mechanical◦ Pneumatic◦ Hydraulic◦ Chemical◦ Thermal◦ Water under pressure ◦ Gravity◦ Potential energy
Hazardous energy sources
3a
The following is a partial list of activities that require LOTO:◦ Constructing◦ Installing◦ Setting up◦ Adjusting◦ Inspecting◦ Modifying◦ Repairing◦ Cleaning equipment
Activities that Require LOTO
5a
Employee trainingo Employees must receive refreshing training
once a year Periodic inspectionso Management will conduct inspection of a lock-
out tag-out procedure in a random manner once a year
o If the audit reveals that an employee is not following the lockout/tagout procedures, the employee will be required to take the refresher training

Any other equipment for which maintenance activities represent a risk to the maintenance operator
The following steps apply to the
lockout/tagout procedure
1. Prepare for shutdown
2. Shutdown
3. Isolate equipment from energy source
4. Apply lockout or tagout device
5. Release of stored energy
6. Verify isolation
Lockout/ Tagout Procedure
6a
Step one: Know the type and magnitude of energy
source Know the hazards of the energy source Know the methods or means to control it
Step two: Turn off equipment using normal controls Use orderly shutdown
Prepare for shutdown
6b
Shutdown
Step three:
Isolate equipment
from energy sources
Secure lock to energy
isolating device
Isolate equipment
8a
Step four: Notify affected employees Attach lockout/tagout
devices Only authorized employee
can attach or remove lockout and tag-out devices
Devices must be durable Devices must identify
person who applied them
Apply devices
9b
Step five: Relieve stored energy Verify machine isolation from energy Relieve pressure in compressed air line Add interference elements if applicable
Release stored energy
10a
Verify isolationStep six: Verify that the machine is de-energized Verify that the machine is isolated Verify that stored energy has been released
Authorized employee must have his/her own device
Devices must be used to control energy only
Devices could be:◦ Locks◦ Tags◦ Chains◦ Wedges◦ Key blocks◦ Adapter pins
Self-locking fasteners
Lockout devices
