CHAPTER 1

PROGRAMS, REPORTS, AND RECORDS

As you advance in the GS rating, you undoubtedlywill find that much more of your time is spent in thetraining and administration of subordinates. This is asit should be, for knowledge must be passed from seniorto junior. The most knowledgeable persons must be incharge. As a GS supervisor, you should not allowyourself to constantly be dragged into a maintenanceposition. If you do, your effectiveness as a leader willsuffer. Weak leadership usually results in disharmonyand, consequently, a poorly run, ineffective division orwork center. This chapter addresses some of your

administrative responsibilities as a First Class or ChiefGas turbine Systems Technician.

Administer ing and t raining subordinates on

programs, reports, and records are never-endingresponsibilities. Every day, whether you realize it ornot, you administer people and programs and trainjunior personnel. You cannot have too much of either.(Although you can have too much paper work in yourtraining and administration programs making themu n m a n a g e a b l e . ) M u c h o f y o u r t r a i n i n g a n dadministration is of an informal nature. A good leaderuses good skills routinely and instinctively. However,formal programs in some areas of training do requiremore than instinct. Specific directives issued by

superiors must be followed to conform to specificstandards. Administration and training, whether formalor informal, are important responsibilities. They needto be taken seriously by all senior Gas turbine SystemsTechnicians.

TAG-OUT PROGRAM

An effective tag-out program is necessary because

of the complexity of modem ships. Tag-out is alsonecessary to avoid the cost, delay, and hazards to

personnel that could result from the improper operationof equipment. The purpose of the equipment tag-out

program is to provide a procedure that preventsimproper operat ion of components , equipment ,systems, or a portion of a system isolated or in anabnormal condition. This procedure also should be usedwhen other safety devices, such as blank flanges, areinstalled for testing, maintenance, or casualty isolation.

The use of DANGER or CAUTION tags is not asubstitute for other safety measures, such as lockingvalves, pulling fuses, or racking-out circuit breakers.Tags attached to valves, switches, or other componentsshould indicate restrictions on operation of systems orequipment, or restrictions necessary to avoid damage tosafety devices. Never use danger or caution tags foridentification purposes!

All procedures in the program are mandatorystandardized tag-out procedures used by all ships andrepair activities. The program also provides a procedurefor use when an instrument is unreliable or not in anormal operating condition. It is similar to the tag-outprocedure except that labels instead of tags are used toindicate instrument status. The tag-out program mustbe enforced during normal operations as well as duringconstruction, testing, repair, or maintenance. Strictenforcement of tag-out procedures is required by bothyou and any repair activity that may be working on yourequipment.

REVIEW AND MONITOR PROGRAMPROCEDURES

As stated in the previous paragraphs, strictadherence to tag-out program procedures is paramount.A brief description of the tag-out program was providedin the Gas Turbine Systems Technician (Electrical)3/Gas Turbine Systems Technician (Mechanical) 3,volume 1. You should already know the programprocedures as they pertain to the role of the maintenanceperson. Now as you move toward a more supervisoryrole, you will be required to have a much larger depthof knowledge. The one-sided program perception is inthe past. You must now understand the program’s innerworkings to maintain a safe environment. A moredetailed description of the required tag-out programprocedures is provided in Standard Organization andRegulations of the U. S. Navy, OPNAVINST 3120.32series.

REVIEW AND MONITOR PROGRAMEFFECTIVENESS

There are a couple of ways to review and monitorthe tag-out program’s effectiveness. The first of which

1-1

is pretty obvious. Were there any personnel injuries ordamaged equipment because of violations to the tag-outprogram? This first method sounds good, but it is notalways accurate. The second method (required) reallydoes not take that much time if performed consistently.Use of the second method also will ensure that personnelinjuries and equipment damage do not occur. Whatmethod are we referring to? It is the audit portion of theprogram.

As a maintenance person you probably were notconcerned with the audit portion of the program. Thatis, unless there was a discrepancy found on anequipment tag-out that you were responsible for. Butnow as a GS supervisor your responsibilities havechanged. You will probably be in charge of a workcenter, and as you continue to progress you willprobably qualify as an EOOW/EDO. Eventually youwill be required to know all aspects of the program.Now take a look at how tag-out audits should beconducted.

All tag-out logs (records) must be kept in thespace(s) designated by your ship’s ins t ruct ion.Normally, these records for the engineering departmentwill be kept in the central control station (CCS).Supervisory watch standers (EOOWs/EDOs) mustreview these records as part of the watch-relievingprocess.

Checks and audits of all tag-outs must be conductedevery two weeks. However, these requirements may besuperseded by your type commander (TYCOM) or evenyour own ship’s instruction. Remember, just as withPMS, audit frequency can only be increased, notdecreased.

1. All outstanding tags listed on the Tag-out RecordSheet must be checked as correctly installed byvisual comparison of the information on the tag,the record sheet, and the item on which the tagis posted. when a valve or switch position isprescribed, a visual check that the item is in itsproper position is made unless an operation suchas removal of a cover, cap, or closure is required.No operation of a valve or switch is authorizedas part of a routine tag-out audit. In addition, aspot check of installed tags should be conductedto ensure that tags so checked are effective (thatis, covered by an active Tag-out Record Sheet).Report all discrepancies in the check of actualposition at once to the EOOW/EDO beforeproceeding any further with the tag audit. Thedate, time, discrepancies (including correctiveactions), and signature of the person conducting

2.

the check is logged on each Tag-out RecordSheet under the last tag listed.

When the actual position of a DANGER-taggedvalve is in question, the EOOW/EDO, with thespec i f i c pe rmi s s ion o f t he r e spons ib l edepartment head, if available, may authorizetwo people to independently check the positionof the specific valve(s).

NOTE

Checking the position of a valve is done only byattempting to turn the valve handwheel/operator asmall amount in the SHUT direction.

3.

4 .

This is an approved exception to the prohibitionon operation of DANGER-tagged equipment.This valve position check must be performedusing the applicable approved procedures forvalve lineup checks.

All outstanding Tag-out Record Sheets areaudited against the Index/Audit Record section.As part of the audit, each Tag-out Record Sheetis checked as previously specified. The date,discrepancies noted, and signature of the personconducting the audit are logged by a line entryin the Index/Audit Record section of the tag-outlog.

Checking the installation of instrument labelsand auditing the logs must be conducted in thesame manner as a tag-out audit.

To ensure that tag-out/label procedures are enforcedproperly, the cognizant department head (engineerofficer) frequently checks the tag-out log, notes errors,and brings them to the attention of those responsible.The completed Tag-out Record Sheets and InstrumentLogs are removed by the department head (engineerofficer) after the review.

Remember, a violation of any tag compromises theentire tag-out system and could in itself have seriousconsequences.

All loose tags that have been removed must bedestroyed.
