X-Ray Tube Hoist

Whenever the x-ray tube is removed or installed, a tube hoist must be used. When the tube hoist is
used, one (1) person can perform a x-ray tube change.
2.3.2.4

Front and Rear Cover Dollies

The front and rear covers have been designed to safely removed by one (1) person, using the cover
dollies supplied with your system. These cover dollies must always be used, because the weight of
these covers could cause injury. Both the installation manual and system manual describe how to
assemble and use these devices.
2.4

Chemicals and Materials

Always wear personal protection equipment to prevent inhalation, digestion and absorption of any
substance through the skin, eyes, nose or mouth.
2.4.1

Slip-Ring Brush Dust and Debris

Avoid inhalation and digestion of slip-ring brush dust. The slip-ring brushes are made of carbon
(refer to the MSDS for these materials). Carbon is the conductive material used to pass power and
signals to the slip-ring platters. As the slip-ring brushes wear, fine particles of carbon are released.
This dust may become an inhalation hazard for individuals with respiratory aliments or diseases. It
is recommended that a respirator be worn during service.
2.4.1.1

Cleaning Equipment

Use a HEPA (High Efficiency Particulate Air) vacuum cleaner to remove residual brush debris. Do
not use a standard vacuum cleaner, because it cannot filter out all of the debris and will exhaust it
back into the air. If a HEPA vacuum cleaner is not available, use alcohol soaked paper toweling to
wipe surfaces clean. This method must be followed up by vacuuming with a HEPA vacuum, when
available.
2.4.1.2

Personal Protection Equipment (PPE)

• Safety Glasses
• Neoprene or Nitrite Gloves
• Respirator (Recommended)
2.4.1.3

Recommended Cleaning Procedure

DANGER TAG AND LOCKOUT SYSTEM POWER BEFORE WORKING AROUND OR
PERFORMING ANY SLIP-RING MAINTENANCE.
To clean the slip-rings, proceed as follows: Remove all existing brush debris from the brush blocks,
brackets, and surrounding areas, using a HEPA (High Efficiency Particulate) vacuum cleaner. Use
the HEPA vacuum cleaner to remove all brush debris that may have been deposited on the gantry
base and floor during servicing. Never use rags or cloths on the slip-ring and brushes.
CAUTION When cleaning the slip-ring and brush area, do not touch the slip-ring or the brushes with
your bare fingers. Skin oil can damage the rings and brushes.
