This policy is in effect even though it has not gone through the policy review process.
All laboratory equipment which may potentially be contaminated by hazardous, radiological, or biological materials must be safely and properly prepared for service or repair by University Facilities Operations, or by commercial service vendors.
The University at Buffalo will make every effort to safely and properly prepare laboratory equipment which may be potentially contaminated by hazardous, radiological, or geological materials, for service or repair by University Facilities Operations or by commercial service vendors. Adherence to these procedures is necessary to ensure that service employees are not needlessly exposed to potentially dangerous materials and that no materials are inappropriately released to the environment.
This procedure applies to all potentially contaminated equipment located within any laboratory where radiological, hazardous chemical, or biologically hazardous materials are used, created, or stored. This may include, but is not limited to, fume hoods, autoclaves, centrifuges, refrigerators, freezers, and incubators (hereafter equipment).
This procedure applies to equipment located within both campus facilities and off-campus facilities.
University at Buffalo Facilities.
Any laboratory equipment used for research or storage of research materials, including but not limited to fume hoods, autoclaves, centrifuges, refrigerators, freezers, incubators, etc.
Hazardous, radiological, or biological materials.
Safe or Safety
Having no exposure to potentially dangerous concentrations of materials.
Commercial service/repair vendors or contractors.
Complete the Checklist for “OK to Service” Certification of Equipment Containing Hazardous Chemicals and Biological Agents and the Checklist for “OK to Service” and Unrestricted Release of Equipment Used with Radioisotopes forms.
In general, before servicing, all hazardous chemical, radiological, or bio-hazardous materials must be removed from equipment and stored or disposed of in accordance with established procedures. However, materials may remain within equipment if there will be no direct contact with the materials in the course of servicing the equipment. For example, materials may remain within a refrigerator or freezer while it is being serviced as long as service providers need not work inside the refrigerator, the materials are isolated inside the refrigerator to prevent contact, and there is no dripping or leakage from the interior. This presumes that there is no need to tip or invert the equipment.
In general, all hazardous chemicals, radiological, or bio-hazardous materials must be removed from equipment surfaces (both internal and external) before the equipment is serviced. However, as outlined in Material Removal above, it may be appropriate to only partially decontaminate the equipment in consideration of the nature of the service to be performed, and which surfaces workers are expected to come in contact with.
It is strongly recommended that service workers and lab personnel discuss the proposed service in advance to mutually determine the required level of decontamination.
Decontamination will be performed as outlined herein.
Radioactive contamination will be removed by standard radiological decontamination methods. The maximum level of residual radioactivity will be determined by EHS policy or by Chapter I, Part 16 of the State Sanitary Code, whichever is more limiting. Surveys will be performed to demonstrate that the decontamination limit has been achieved. These surveys will be documented, and records will be available for inspection by EHS or by the Department of Health. All waste generated in the course of decontamination will be disposed of as radioactive waste. After decontamination, radioactive labels and stickers will be removed, defaced, or temporarily covered.
Chemical residues will be removed, neutralized, or otherwise rendered non-hazardous using an appropriate method determined by the chemical and physical characteristics of the contaminant(s), and the physical nature of the equipment. Hazard labels will be removed, defaced, or temporarily covered as appropriate. The decontamination method will be documented, and records will be available for inspection by EHS. Any incidental wastes will be disposed of properly.
Bio-hazardous contaminants will be removed or rendered non-pathological. Typically, this will be accomplished using a bleach solution, other chemical means, and or by steam sterilization. Hazard labels will be removed, defaced, or temporarily covered as appropriate. The decontamination method will be documented, and records will be available for inspection by EHS. Any incidental wastes will be disposed of properly.
If decontamination cannot be achieved, it may be appropriate to cover contaminated surfaces with impermeable materials, such as polyethylene sheet. If this is done, any contamination, which has been temporarily covered over, must be clearly labeled and explained to service personnel. The covered material will be disposed of as appropriate for the contaminant hazard.
Once materials removal and decontamination have been completed, the principal investigator (or other authorized individual as designated in writing), will affix a copy of the Equipment “OK to Service" Certification form to the equipment. All sections of the form shall be completed with the relevant information or “NA” as appropriate. A copy of the form will be retained, and will be available for inspection by EHS.
Some equipment within laboratories has essentially no potential for contamination. This includes computers and office equipment, audio-visual equipment, cameras, optical equipment, food storage refrigerators, etc. No decontamination of this equipment is required and the “No Potential for Contamination” box will be checked on the release form. In addition to this check off, the name and date section should be completed, however, the other sections may be left blank.
Once the equipment release/certification form has been affixed to the equipment it may be serviced. University Facilities Operations will not service any equipment, which has not been tagged. Laboratory personnel should be readily available to answer questions, and should explain any special considerations to service personnel.
All special or unusual problems will be referred to EHS for resolution. Any deviation from the requirements of this procedure must be approved in writing by EHS.
