LOCKOUT PROCEDURE
• Applicable to Strasbaugh Polishing, Lapping, Grinding, and Cutting Machines
• Conforms to ANSI Z244.1-1982
Purpose
This procedure establishes the minimum requirements for lockout of energy sources that
could cause injury to personnel. All maintenance personnel, operators, and machine owner
employees shall comply with the procedure.
Responsibility
The responsibility for seeing that this procedure is followed is binding upon all machine
maintenance personnel. All machine maintenance personnel shall be instructed in the
safety significance of the lockout procedure by the information contained herein and
instruction provided by the machine owner designated safety personnel. Each new or
transferred affected operator or maintenance person shall be instructed accordingly in the
purpose and use of the lockout procedure.
Preparation for Lockout
Maintenance personnel authorized to perform lockout shall be certain as to which switch,
valve or other energy isolating devices apply to the equipment being locked out. More than
one energy source (electrical, mechanical, or others) may be involved. Employees shall
clarify the identification of questionable sources with their supervisors. Before lockout
commences, job authorization should be obtained.
Sequence of Lockout Procedure
1. Notify all affected employees that a lockout is required and the reason therefore.
2. If the equipment is operating, shut it down by the normal stopping procedure (depress
stop button, open toggle switch, etc.).
3. For each energy source, operate the switch, valve, or other energy isolating device so
that the energy source(s) (electrical, mechanical, hydraulic, etc.) is disconnected or
isolated from the equipment.
Stored energy, such as that in capacitors, springs, elevated machine members,
rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.,
must also be dissipated or restrained by methods such as grounding, repositioning,
blocking, bleeding-down, etc.
4. Lockout the energy isolating devices with an assigned individual lock.
5. After ensuring that no personnel are exposed and as a check on having disconnected
the energy sources, operate the push button or other normal operating controls to
make certain the equipment will not operate.
CAUTION: Return operating controls to neutral position after the test.
6. The equipment is now locked out.
