Section 325.5299. Class D operations.

(1) Industrial radiography conducted under conditions not meeting the provisions and requirements of rules  294  to   298  shall  be classified as class D operations and shall not be operated longer than 30 days unless written authorization is granted by the department.

(2)  Written authorization may be granted by the department for class D operations longer than 30 days but not longer than 6 months when an undue and unnecessary hardship may result from the 30 day limitation. Written request by the licensee or registrant for this authorization is required and shall describe the hardship involved as well as provide written assurance of compliance with the requirements of these rules for class D operation.

(3)    Notwithstanding subrules (1) and (2) a person routinely engaged in providing industrial radiography services with mobile or portable sources of radiation at temporary job site locations may conduct such class D operations without time limitation subject to the following conditions:

(a)    The person shall hold an unexpired certificate of registration from the department or specific license from the department, the NRC or  an  agreement state.

(b)  The person shall give written notice to the department at least 2 working days before starting radiographic work at a job site. The notice shall include the radiographer's name; a description of each source of radiation; the nature, duration and scope of use; and the exact location of each job site. If for a specific case the 2 working-day period would impose an undue hardship on the person, upon application to the department, he may arrange for other notification to comply with the intent of this requirement.

(c)     These class D operations shall be limited  to  locations  and circumstances which cannot meet the provisions and requirements of permanent installation classification without undue and unnecessary hardship.

(d)   A copy of written operating and emergency procedures shall be filed with and approved by the department.

(e)   Upon reasonable notice from the department the person shall submit to the department or otherwise make available copies of specific   records pertaining   to  radiographic operations  and  personnel   conducting   these operations within this state.

(4)  A fence, rope or other suitable barrier shall be erected along the 5 mR/hr contour line during class D radiographic operations to exclude unauthorized persons from the radiation area.

(5)  The radiation area and high radiation area shall be posted with caution signs as specified in rules 224 to 231.

(6)      A personnel monitoring device such as  a   film  badge  dosimeter   or thermoluminescent dosimeter,  shall   be  permanently   assigned  to  each occupationally exposed individual. This monitoring shall be continuous during employment as a radiation worker.

(7)   Personnel exposure records shall be kept on permanent available file for examination by the department. A  copy  of  the  most   recent  record including current, quarterly, annual and lifetime cumulative totals for each monitored individual present at a temporary job site shall be available at the job site for examination by the department. A current supplemental daily dosimeter log shall also be available at the job site.

(8)   The inside of the driver's compartment of the transport vehicle used to transport class D radiographic exposure devices shall be conspicuously posted with emergency instructions including the procedure for notifying the Michigan Department of Public  Health,  the Michigan Department of State Police, and other emergency agencies in event of accident or fire and the procedure for minimizing exposure to persons in the event of an accident.

(9)    Written operating and emergency procedures shall be available at each class D radiographic operation.

[Note: The requirements of this rule that pertain  to  radiation   machine registration, licensing, or compliance are under the purview of the Michigan Department of Consumer & Industry Services.]

[Note: As a result of Executive Orders 1996-1 and 1996-2, the authority, powers, duties, functions, and responsibilities of the  radiation  machine registration, licensing, and  compliance  program   were  transferred  to the Michigan Department of Consumer & Industry Services. With respect to machine sources of ionizing radiation, any reference in these rules to the Michigan Department of Public Health should now reference the Michigan Department of Consumer & Industry Services.]
