Equipment Service - Chemicals and Materials
Always wear personal protection equipment to prevent inhalation, digestion and absorption of any substance through the skin, eyes, nose or mouth.
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 Material Safety Data Sheets (MSDS) for these materials). Carbon is the conductive material used to pass power and signals to the slip ring platters.
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.
1.2 Personal Protection Equipment (PPE)
-
Safety Glasses
-
Neoprene or Nitrite Gloves
1.3 Recommended Cleaning Procedure
|
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.

1.4 Clean-up and Personal Hygiene
After servicing slip ring component and the area, wash your hands thoroughly with soap and water. Dispose of gloves and rags properly.
Place all materials that contain brush debris (such as the HEPA vacuum cleaner filter, paper toweling, gloves, and old brush assemblies) in a sealed plastic bag and return to the GE Recycling Center:

1.5 Hazardous Materials and Waste
GE Field Personnel are provided EHS training upon employment and must complete annual training there after which defines how to manage hazardous materials while servicing GE equipment. Refer to EHS101 - GE course number GEHC-CM2356T-EN. See training material excerpts below:
-
Hazardous waste generated while servicing equipment at a customer’s site belongs to the customer and must be disposed of by the customer.
-
FE’s are not permitted to ship any chemical waste material!
-
When in doubt about the waste categorization or disposal methods contact your Field EHS Specialist or GE Healthcare Renewable Resource Center.
-
Some repairable or recyclable parts may contain hazardous materials such as nickel cadmium or lithium batteries, mercury switches, etc.
-
GE personnel can contact their EHS Zone Lead representative for help if required regarding all questions related to Material Safety Data Sheets (MSDS), Environmental Health & Safety (EHS), and Personal Protective Equipment (PPE) programs.
2 Oils (Tube, Tank and Hydraulic)
Oil resistant gloves should be worn when working with oil or performing clean-up of it. Dispose of chemicals, rags and materials in accordance with hospital and local government environmental and safety requirements.
3 Lead
Wear gloves and wash hands after handling lead. The CT detector has a trace amount of Chromium (Cr) in its construction. CT detectors can be returned to GEMS for proper disposal. There is also a small amount of lead in the collimator.
4 Heat Sources
The X-Ray tube casing, plumbing and radiator can become hot enough to cause minor burns, if not allowed to cool sufficiently. Please allow sufficient time for this equipment to cool adequately before performing any service.
5 Adhesives, Cleaners, and Paints
All adhesive and cleaning compound brand names referred to within the service procedures may have equivalent products available locally. Paints are specific to GE products and are not available locally.
Some chemicals, cleaners and adhesives brands such as Loctite, RTV, Scrubbing Bubbles (Dow), etc., or their equivalent are available through the GE Healthcare spare parts (FRU) ordering/management system. These are to be used exclusively on GE Healthcare products or products serviced by GE Healthcare. The distribution of these chemicals to any person not employed by GE Healthcare or not under contract with GE Healthcare is strictly prohibited. The use of these products for any other purpose other than those specific uses defined in the service documentation is strictly prohibited. For assistance with Environmental Health & Safety (EHS) issues contact your Zone Lead representative.
