Hall A Specific Hazards

There are several Hall A-specific hazards which you will see in your required walk- through. These include: the electron HRS Power Supplies, the hadron HRS Power Supplies, the magnetic field in the first quadrupole and the first dipole of the spectrometers when the power is on (flashing red lights indicate when power is on); the target area; the target chamber vacuum windows; the Hall A cyrogenic target system; the beam dump; the steps going up to beam line; the HRS detector hut vacuum window; the drift chamber windows; possibly damaged equipment; high power-low voltage or high-voltage electronic equipment; the high-voltage feed to PMTs; and slip, trip, and fall hazards. Additional hazards may be present for specific experiments. The specific experiment's safety assessment document must contain these details. Detailed rules specifying who is authorized to work on what equipment within the hall are listed in Chapter , ``Personnel Allowed to Operate Hall A Equipment."
