Improper use of electrical equipment
may result in injury or property damage
Use of electrical equipment and
installations shall conform to good safety practice and applicable laws and
regulations

safety requirements, contact EH&S
Do Not Use
2-wire ungrounded electrical
devices. Departments must purchase only 3-wire grounded equipment. (Exceptions:
"Double insulated" electrical devices and equipment operated under 50 volts.)
Electrical extension cords
or cube taps as substitute for permanent wiring. Never run extension cords
under doors, through windows or holes in walls. Never attach cords to walls
or ceilings. Every device must be plugged directly into a receptacle. (Exceptions:
Heavy duty extension cords may be used for experimental setups, or for portable
tools/appliances used on a transient basis and frequently moved.) The use
of a "Fused UL Rated" multi-outlet strip is permissible as long as it is plugged
directly into a wall outlet.
Worn or damaged electrical
cords, plugs, switches, receptacles, or cracked plastic casings. Electrical
cords must be free of cracks, splices, frayed areas, loose connections, or
other damage.
2-pole to 3-pole adapters,
cube taps, 2-wire ungrounded extensions cords or similar devices. Electrical
devices fabricated for experimental purposes must meet all construction and
grounding requirements of the State of Oregon. Extension cords and similar
devices must be UL listed.
Connections to campus power
sources other than at existing outlets using conventional plug-in connection.
Any hard-wired or special connections must be made or approved by Facilities
Service.
In An Electrical
Emergency:
Dial 911 for emergency aid - Ambulance, Fire Department or Police.
Electrical Operations - Safety Rules
Wear protectivesafety equipment (such
as gloves, hard hats, respirators) as required by OSU policy and supervisors.
Use non-metallic ladders and measuring tapes near
energized circuits and for all electrical work.
Dispose broken glass from burned out lamps of
in trash containers.
Send used fluorescent tubes to EH&S for proper
disposal.
Before starting work on an engine, motor, line shaft,
or other power transmission equipment, a padlocked lock-out device is required to make sure equipment cannot be set in
motion; if it not reasonably possible to use a lock-out device, a "Do
Not Start" tag is to be used .
Each electrician working on equipment which requires
use of a lock-out device will use a personal padlock for which he/she alone has a key. Duplicate
or master keys in the possession of others is prohibited.
A lock-out padlock will be removed only by the
electrician who applied it.
Work being done in manholes or on overhead equipment must be safeguarded by using proper signs and guards around openings
or under work area.
An observer shall be stationed on the surface
when any manhole is entered, regardless of the voltage involved.
Confined spaces (manholes and certain tanks, tunnels,
manholes, etc) can only be entered under the confined
space program.
Specific supvisor review and approval is needed for
work on live lines over 277 volts.
Training is required prior to work with live line tools.
Supervisor approval of work plans is required for high
voltage electrical switching.
Use approved testing equipment when opening primary
and secondary switches to be sure that the system is de-energized. To perform
this job, use approved electrical gloves and with grounding straps. Wear appropriate
eye protection.
Before starting work on a de-energized high voltage
circuit, place warning signs or tags on the control switches where the operation
of such switches would create a hazard.
For work on energized high voltage equipment, at least
two employees are required.
The following protective equipment is mandatory for
employees who perform high voltage switching operations in confined areas
which could produce sparks:
Approved safety hat for electrical work.
Approved switching helmet and eye protection.
Approved electrical gloves and cover gloves.
Knee length flameproof coat.
Safety equipment used for work on high voltage equipment
will be specifically approved by electricians. No substitutions for approved
equipment is permitted.
Inspect each tool or piece of equipment used as safety
devices for high voltage work. Only use equipment in good condition.
