During installations in Hall C, there is often a wide variety of work
in progress, some of it occurring above the floor level. Because of
the risk of falling objects, hard hat use is now required during
installation work. This requirement will apply whenever mechanized
equipment is in use (Cranes, JLG lifts, man lifts, fork lifts), or
when the entrances to the hall are marked with hard hat required
signs.
Hard hats will not be required when fully within the beamline tunnel,
the Spectrometer detector bunkers (HMS & SOS), and the GeP electronics
bunker. The Hall work coordinator may also grant exceptions for
specific work with sensitive equipment when there is no overhead work above
the work area.
