6.1       General Move/Transfer/Closure Preparations

When your laboratory is scheduled for a move, transfer, or closure, the following steps should be followed:

·         Notify the Environmental Health & Safety (EHS) as soon as you are aware of the move/closure.  (Extension 21781)

·         Conduct a complete chemical/glassware inventory and forward copy to EHS

·         Conduct a preliminary laboratory clean-out.

a)      Dispose of expired or deteriorated materials if safe to do so.  If not safe (e.g., peroxide formation), contact EHS for assistance.

b)      Track down the identity of any “unknowns”.

c)      Arrange for safe disposal of chemicals and radioactive materials via the on-line waste disposal system (See Chapter 10 for more information). 

d)      Dispose of biohazardous materials in red bags, by chemical decontamination or by autoclaving.

·         Be prepared:  Have spill clean-up material readily available.

·         Any hazardous materials that will be moved must be placed in secure secondary containment.

·         Arrange with the Animal Resource Center to move any animals.

·         Contact Materials Management for relocation of gas cylinders.

·         Arrange for transport of all radioactive materials by, or under the supervision of, the authorized user.

·         Make arrangements with vendors to delay shipments of orders, if necessary.

·         Clean and decontaminate laboratory hoods with appropriate detergent and/or disinfectant.

·         Do not block access to safety equipment or routes of escape from labs with moving boxes or equipment.

The lab must be empty when the move is complete.  EHS personnel will inspect the lab with the individual responsible for the laboratory to insure that the lab has been cleared.  If the lab has not been cleared properly, the Principal Investigator will be contacted for follow-up response.  The Laboratory Closure and Relocation Check List (See Appendix A) should be completed, signed by a faculty member and EHS representative and then posted on the door.


6.2       Equipment

·         Coordinate the decontamination of the Biological Safety Cabinet to be moved through EHS at least two weeks before the move.  Once moved, they will need to be re-certified before use.

·         Decontaminate all used equipment prior to packing or moving.

·         Chemical residues need to be removed from all work surfaces and equipment.  Lab bench tops must be cleared and cleaned with appropriate detergent or disinfectant depending on laboratory procedures.

·         Tag all equipment that is to be relocated, disposed of or salvaged with the completed “Laboratory Equipment Decontamination Form.”

·         The freezers may be moved with contents inside.  Once the freezer is put back in service, allow the contents to refreeze before checking for broken and spilled material.  Contact EHS for additional information on securely packing contents of freezers and refrigerators.

·         Wipe test all equipment if radioactive materials were used.  Include a diagram of the areas wiped.  Wipe tests should be initiated no later than the day prior to the move.   

 

6.3       Laboratory Equipment Decontamination Form

All equipment that is to be relocated, disposed of or salvaged must be tagged with the completed “Laboratory Equipment Decontamination Form” (See Appendix B).  This form will indicate to the individuals moving or receiving the equipment whether or not the equipment has been used with hazardous chemical, biological and/or radioactive materials.  If the equipment was used with these types of materials, decontamination procedures must be performed by the user prior to removal from or abandonment of the laboratory.  This will ensure that people coming in contact with the equipment do not get exposed. 

If the equipment is being salvaged or sent to inventory, remove all markings denoting its use with hazardous materials before tagging the equipment with the Laboratory Equipment Decontamination Form.  Note:  Inventory and FOAM will not accept any equipment without the Laboratory Equipment Decontamination Form attached.  For questions regarding radioactive decontamination, call 22279.  For questions regarding chemical and biological decontamination, call 21781.
