A petty officer must become a technical specialist in his/her rating. Technical duties which an Engineman must learn to perform efficiently include:

1. Operating internal combustion engines and auxiliary engineroom machinery.

2. Maintaining internal combustion engines and related accessories and equipment.

3. Performing overhaul and repair work on internal combustion engines, using established procedures for disassembly, replacement, and reassembly.

4. Conducting routine tests and inspections of all engineroom machinery.

5. Operating and making repairs to auxiliary boilers and to refrigeration, air conditioning, and distilling systems.

6. Using lathes and other machine shop equipment.

7. Using measuring instruments needed in engine overhaul, such as micrometers, feeler gages, and inside and outside calipers.

8. Reading accurately such instruments as thermometers, pressure gages, and pressure indicators.

Probably you can already do many of these jobs. Others you will have to learn from additional practical experience and through study.

Although you will be learning many new jobs as an EN1, and especially as a ENC, you will be con-cerned principally with directing and observing the work of personnel assigned to you. You will be responsible for their performance and their training in all of the jobs required of an Engineman.

In addition to the duties already mentioned, you will compile necessary data for the preparation of engineering reports and records. It will be your duty to make frequent tours of assigned spaces, and to inspect equipment for proper operation. You will check the auxiliary watch for performance of duty in accordance with standing orders. You will be responsible for the use of the correct operating procedure for all equipment under your jurisdiction. You will be accountable for daily routine inspections, tests, and reports on all equipment that require daily maintenance and testing.

You may be held responsible to the division officer for the proper setting and standing of all watches during your duty period. You may be required to post the daily watch list in the engineroom and may be responsible for instruct-ing and training watchstanders in their duties.

You will instruct lower rated personnel in the correct procedures to be used for casualties involving the engineroom. It will be your responsibility to see that personnel under your supervision learn about the capabilities and limitations of the equipment with which they work, and the procedures to follow should casualties occur.

Safety is a responsibility of all Navy personnel.

As an EN1 or ENC, you will instruct your personnel in shipboard safety precautions, par-ticularly those that are applicable to your division, and will ensure that copies of these precautions are posted in conspicuous places. Most impor-tantly, you will watch for careless methods of workthe frequent source of accidents. You will be expected to set a good example for following safety practices. The example you will set will have a great influence on your people and other personnel. You will watch for and report all unsafe conditions.

To successfully perform your duties, you should know the duties performed in other divi-sions, and how the various shops can help you get a job done. While it is true that many maintenance and repair jobs occurring in your own division can be properly handled from start to finish without the aid of any outside rating, other jobs may be more extensive and may require special skills or equipment not available within your division. Although you and the personnel under your supervision may be able to do the bulk of the work, certain portions of a job may require the skill of an Electricians Mate, a Machinists Mate, a Machinery Repairman, a Hull Maintenance Technician, or people in other ratings. Therefore, you must know what equipment is used by other ratings in the engineering department, and what kind of work can be done with that equipment. Familiarize yourself with the work performed and equipment used in other divisions by observing them at work and by talking to leading petty officers in other ratings. There is no excuse for using unskilled personnel and un-satisfactory procedures when the skill of other ratings and the equipment they use are already available.
