Sealed Source Safety Manual

28 Sealed Source Safety Manual • When not actively being used for field measurements, portable nuclear gauges must be locked and returned to their storage/ transportation case. • When field operations are complete, portable nuclear gauges will be returned to their permanent storage locations as soon as possible. • While the source is in the operator’s possession, the operator will have a copy of ¤ ¤ Sealed Source Safety Manual ¤ ¤ instrument operating instructions ¤ ¤ current leak test certificate ¤ ¤ Inventory and Usage Log Maintenance Procedures • The operator will have received proper instruction on how to clean and maintain the gauge. • Perform routine cleaning and maintenance according to the manufacturer’s instructions and recommendations. • Maintenance or repairs that require source removal must be completed by a licensed service center. Emergency Procedures If the source fails to return to the shielded position (e.g., as a result of being damaged, source becoming trapped below the surface), or if any other emergency or unusual situation arises (e.g., the portable gauge is struck by a moving vehicle, is dropped, or is in a vehicle involved in an accident), • Immediately secure the area and keep people at least 15 feet away from the portable gauge until the situation is assessed and radiation levels are known. Perform first aid for any injured individuals and remove them from the area only when medically safe to do so. • If any heavy equipment is involved, detain the equipment and operator until it is determined there is no contamination present. • From a safe distance that minimizes personal radiation exposure, visually inspect the gauge to determine the extent of the damage to the source, source housing, and shielding. • Portable gauge users and other potentially contaminated individuals should not leave the scene until emergency assistance arrives. At the earliest opportunity after the situation is under control, contact EH&S at (515) 294-5359. After hours, contact the Note: Immediately contact EH&S in the event of an emergency.
