Be Safe or Die


Electrical Safety at the PSFC

Experimental power at the Plasma Science and Fusion Center is brought into NW20 and NW21 at 13.8 kV. Most of the labs are supplied with house power at 120, 208, and 480 V AC. Many experiments operate at very high DC or pulsed voltages, or high currents. Having a good working knowledge of electrical safety is of prime importance to all experimental personnel at the PSFC. Electrical safety training is provided by Assistant Safety Officer Bill Byford (BYFORD@PSFC.MIT.EDU) who is a licensed master electrician.

AC Power

All work done on in house supplied electrical AC systems must be done by a licensed electrician or electricians helper supervised by a licensed electrician.

Qualification for Live Electrical Work

Those doing live electrical work at greater than 50 v must be qualified to do so. Electrical training is offered by Bill Byford several times per year.

Lockout/Tagout

The heart of the program is the lockout tagout procedure. All high energy systems which could release that energy to the worker must be locked and tagged out before work ensues. The lockout/tagout program is administered by Bill Byford and Jim Irby.

Personnel Requirements for Live Electrical Work

Whenever possible, working on live electrical systems is to be avoided. When it is not possible to avoid, guidelines are provided for the minimum number of people who must be present, what approvals must be obtained, and what controls should be used for the available voltage or stored energy in the system.
