2.4.7    Notifying the RSO in writing when time away from Cornell is expected to be six (6) weeks or more.  A substitute permit holder shall be named and agree in writing to accept the responsibility for the permit for the duration of the leave.  Approval of the arrangement will be made by the RSO.  A permit amendment is issued to reflect the change.  The substitute permit holder must hold a currently active permit. 

2.4.8    Notifying the RSO 30 days in advance and complying with proper procedures for termination of employment, termination of the permit, or termination of any experiment using radioactive materials.  Under the terms and conditions of the permit, the permit holder must transfer or dispose of all radioactive materials assigned under the permit.  Particular care should also be exercised to see that personnel monitoring devices (e.g., personnel badges) are returned to the RSO.  The permit holder shall request a final termination survey (see Special Procedure #8, Release Criteria for Facilities and Equipment Involved with the Use of Radioactive Materials).

2.4.9    Ensure that all users know how to access and have reasonable ability, within the main lab or space where radioactive materials or radiation sources are used, to access the online Radiation Safety Manual.  The online version is available at the following website: https://sp.ehs.cornell.edu/lab-research-safety/radiation/radiation-safety-manual/Pages/default.aspx

            The online version of the Radiation Safety Manual is the preferred method of accessing the manual in the lab.

            Alternatively, Permit Holders who choose to maintain a hard copy manual or local electronic copies will be responsible for ensuring the manual in their lab is current.

            The Permit Holder must maintain the most current printed copies of the Permit and Permit Application in the main lab for users to view.

2.5.7     Keeping the laboratory neat and clean.  The work area should be free from equipment and materials not required for the immediate procedure.  Keep or transport materials in such a manner as to prevent breakage or spillage (secondary containment), and to ensure adequate shielding.  Whenever practical, keep work surfaces covered with absorbent material with plastic backing, preferably in a stainless steel tray or pan, to limit and collect spillage in case of accident. 

2.5.8     Labeling and isolating radioactive waste and equipment, such as glassware, used in laboratories for radioactive materials.  Once used for radioactive substances, equipment shall not be used for other work, sent from the area to central cleaning facilities or repair shops until demonstrated to be free of contamination.

2.5.9     Requesting RSO supervision of any emergency repair of contaminated equipment in the laboratory by personnel from outside the lab or repair/service vendors.  At no time shall servicing personnel be permitted to work on equipment in radiation areas without the presence of a member of the laboratory staff to provide specific information. See Special Procedure #8.

2.5.10   Reporting accidental skin contamination, inhalation, ingestion, or injury involving radioactive materials or radiation sources to Cornell Police at 911.  Cornell Police will notify the EHS HazMat team.  (See Chapter 10, section 10.2.2.7)  All affected individuals shall carry out the recommendations of the emergency response personnel and/or RSO, as well as cooperate in any and all attempts to evaluate exposures. 

2.5.11   Carrying out decontamination procedures when necessary and taking the necessary steps to prevent the spread of contamination to other areas. 

2.5.12   Complying with requests from the RSO for internal exposure measurements and the submission of samples for radio-bioassay.  Requests for these tests will be made in the case of workers using significant quantities of unsealed radioactive materials or in case of potential accidental inhalation or ingestion. 

2.5.13   Promptly reporting any condition that may cause a violation of regulations or unnecessary exposure to radiation or to radioactive materials.  (See Chapter 11). 

2.5.14   Performing only authorized protocols using the authorized isotopes and limits, authorized rooms and abiding with all conditions listed in the permit.  Confer with the permit holder about an amendment to the permit if a change is necessary to accommodate needs (see Special Procedure #14, Permit Amendment and Process).
