Individuals involved in operations which utilize, at any one time, more than 100 millicuries of tritium in a non-contained form, other than metallic foil, shall have a bioassay performed within one week following a single operation, and at weekly intervals for continuing operations.
Tritium shall not be used in such a manner as to cause any individual to receive a radiation exposure such that urinary excretion rates exceed 28 microcuries of tritium per liter when averaged over a calendar quarter.
If the average concentration of tritium in urine for an individual during a calendar quarter is less than 10 microcuries per liter, urinalysis may be performed on that individual at monthly intervals for the following calendar quarter and may continue at monthly intervals so long as the average concentration in a calendar quarter remains below 10 microcuries per liter.
The urine specimen should be collected on the same day of the week, whenever practical.
Scheduling of routine bioassays is the responsibility of the individual radiation worker.
Operations which utilize 100 millicuries or more of tritium in a non-contained form, other than metallic foil, shall be performed in either a closed system or in a certified working fume hood. Operations in biosafety cabinets or on benchtops are prohibited.
Persons with more than 10% of the applicable limit for internal exposure of tritium will be counseled by a Radiation Safety staff member.
The Principle Investigator and Radiation Safety will evaluate the probable causes of the exposure and changes in procedures, work habits, or equipment will be recommended as appropriate.
A written summary of the investigation results, including potential corrective actions, should be provided to the Radiation Protection Committee.
may include using a chemical fume hood or snorkel, containing chemicals and other materials in the appropriate containers, eyewashes and safety showers, or increasing the ventilation in a particular area to minimize an exposure to a hazardous substance. Making sure that all equipment in your laboratory are properly maintained and inspected on a regular basis is an integral part of engineering controls. If you have any issues with the equipment in the laboratory, please contact Facilities Department via phone at (404)413-0700 to submit a service request.
include altering the way in which a procedure is done, monitored, and/or restricted. Examples of an administrative control is to limit the exposure time of a worker, creating written standards operating procedures (SOPs), enforcing rules about daily housekeeping, and performing regular equipment maintenance. Be sure to adhere to all of the rules and regulations established by your department/Principle Investigator, Georgia State University, and the local, state, and federal agencies.It is the responsibilities of all laboratory staff and Principle Investigators to establish administrative controls within their laboratory space. When setting these parameters and procedures, please be sure to follow safety guidelines set by federal, state, and local entities.
should only be considered as a supplemental control when engineering controls are not adequate. It should be used to increase the level of safety protection from chemical, biological, and physical hazards to protect you from harm should an accident occur. PPE should also be on hand for use during emergency response and cleanup procedures. PPE includes items such as gloves, safety glasses, protective shoes, earplugs or muffs, hard hats, lab coats, aprons, and respirators and masks.There are many different brands and a variety of materials that protect against different hazards of varying degrees. Make sure to check the packaging of your PPE to determine if that is the right type of glove, eyewear, lab coat, etc. to protect you against the hazard(s) you are exposed to.
Accidents that take place in the laboratory and involves any hazardous materials should be immediately reported to GSU Police and Research and Environmental Safety. Our office is prepared to assist with hazardous materials clean up. Any incidents involving fire and injury must be reported immediately to local authorities (911 or GSU Police at (404)413-3333).
