more work centers. These chief petty officers shall be referred to as "group supervisors." Group supervisors are responsible for the proper performance of the 3-M Systems functions within their respective work centers.
The senior enlisted person will be designated as the work center supervisor, responsible for the effective operation of the 3-M Systems within the work center. The work center supervisor will assign the maintenance personnel various PMS tasks.
Junior Dental Technicians are the maintenance personnel in the dental center and report to the work center supervisor. Their 3-M Systems duties include, but are not limited to, the following:
Perform assigned scheduled maintenance requirements using MRCs (Maintenance Requirement Cards), TGLs (Tag Guide Lists), and EGLs (Equipment Guide Lists) as indicated by the division's weekly schedule.
When performing PMS, maintenance personnel will notify the work center supervisor when :
Anything on an MRC is not fully understood, appears to be incorrect, or cannot be accomplished as written on the MRC.
Tools, materials, etc., prescribed by the MRC are not available.
Any doubt exists about capability, training, or experience to properly perform the MR (maintenance required).
Factors exist that would make performance of the MR unwise or dangerous.
Equipment deficiencies or casualties (casualties meaning down equipment not medical casualties) are discovered.
Maintenance personnel will inform the work center supervisor when planned maintenance requirements have been completed and sign the accountability log. The work center supervisor must be informed of any problems encountered under current schedules and/or MRCs.
The Work Center PMS Manual reflects the portion of the PMS Master File (maintained by 3-M Systems coordinator) that contains only the planned maintenance requirements applicable to a particular work center. It will be retained in the working area near the Weekly PMS Schedule. Maintenance personnel will be familiar with the following information contained in the Work Center PMS Manual:
List of Effective Pages (LOEP)
Maintenance Index Page (MIP)
Maintenance Requirement Cards (MRCs)
The LOEP, as shown in figure 12-1, provides a listing of the Maintenance Index Pages (MIPS) and system equipment not requiring PMS that is assigned to each work center. Note that the dental and medical departments fall under one work center as illustrated in figure 12-1.
MAINTENANCE INDEX PAGES Maintenance Index Pages (MIPs) are prepared and issued for each installed system/equipment for which PMS support has been established. MIPS are basic PMS reference documents. Each is an index of a complete set of Maintenance Requirement Cards (MRCs) applicable to a ship's system, subsystem, or equipment. Figure 12-2 illustrates an MIP for a Dental Delivery System (DDS). Note that this DDS has 4 different MRCs (identified by the box containing SYSCOM MRC Control No.).
MAINTENANCE REQUIREMENT CARDS Maintenance Requirement Cards (MRCs) provide detailed procedures for performing maintenance requirements and describes who, what, how, and with what resources a specific requirement will be accomplished. Personnel performing the maintenance should always follow any safety precautions noted on the MRC's and should become familiar with any chemicals used during the PMS including the correct use of any personal protective equipment required during the handling of chemicals or during the maintenance procedures. Figure 12-3 illustrates one of the four MRCs for the DDS. The OPNAVINST 4790.4 provides guidance and requirements for all of the blocks and codes listed on the MRC.
