What are the uses of lockout

    The purpose of a “Lockout/Tagout” procedure is to protect employees from machines and
    equipment capable of causing injury due to unexpected energization, release of stored
    energy or the start-up of equipment while an employee is performing maintenance or
    servicing equipment. To inform Contractors of their responsibility when performing
    lockout/tagout activities at NSU to ensure all employees potentially affected by energization
    of building systems are properly protected and the EH&S office notified.


NSU ensures all its employees; faculty, students, visitors and property are protected by
complying with the OSHA Standard, 29 CFR 1910.147 – Control of Hazardous Energy
Sources (Lockout/Tagout).
NSU maintains a Lockout/Tagout program for its maintenance employees, where standard
locks and tags are used to control the start-up of equipment that is being serviced or
maintained by employees.
Controlling hazardous energy may involve disconnecting motors, de-energizing electrical
circuits or discharging capacitors.
Hazardous energy found at NSU may be of the following types:


Contractors and employees must follow the requirements for Lockout/Tagout as outlined
1) The Contractor is responsible for implementing and maintaining his/her own
Lockout/Tagout program in accordance with OSHA regulations.
2) The Contractor shall submit a copy of their Lockout/Tagout policy to the EH&S office

3) The Contractor is to ensure all employees are trained in Lockout/Tagout procedures in
accordance with OSHA regulations prior to performing the work.
4) The Contractor will not perform any work on electrical circuits, machinery or lines
carrying hazardous liquids or gases under pressure until appropriate protective
measures have been instituted by the Contractor.
5) If the Contractor is required to lock out University equipment, the Contractor will
notify the EH&S officer. Under no circumstances will a Contractor lock out NSU
equipment without permission.
6) The Contractor is prohibited from disengaging any warning devices or alarms without

lockout devices, shift changes or staff changes.

out and/or tagged out during the course of the project. The log shall contain details of
which equipment was worked on, the date the work was performed, and the name of

ensure it meets OSHA standards, and all locks are removed at the end of the job with
