Engineering Documentation We Love Paperwork!
Introduction Technical Information Systems Engineering Operational Guidelines Logs and Records Tagouts
Technical Information Sources Naval Ships’ Technical Manual (NSTM) Provides general interest information to entire fleet (electrical safety precautions, shipboard firefighting, damage control) Ship Information Book (SIB) Specific ship information generated by the shipyard who built the ship (schematics, equipment information, data)
Technical Information Sources Equipment Technical Manuals Specific information and instructions for individual equipment Written by manufacturer Blueprints and drawings Microfiche & paper form Used for piping systems, wiring diagrams, & drydocking plans
Engineering Op Guidelines (Conventional) Engineering Operational Procedure (EOP) Instructions and guidelines for completing all normal evolutions (ex: plant startup) Engineering Operational Casualty Control (EOCC) Instructions and guidelines for combating all casualty conditions (ex: steam line rupture)
Engineering Operational Guidelines (Nuclear) Reactor Plant Manual (RPM) Provides all instructions and guidelines for normal evolutions and casualty conditions for the reactor plant Steam & Electric Plant Manual (S&EPM) Same as RPM but for engineering plant (electric plant and propulsion plant)

Tagouts Purpose: Aid in ensuring safety of personnel and equipment Danger Used when safety of personnel and/or equipment would be jeopardized Prohibits operation of equipment to which the tag is attached Mechanical or Electrical systems
Danger Tag
Tagouts Caution Convey amplifying information or special instructions to ensure safe operation of system or component
Caution Tag
Writing Tagouts One person identifies scope of work and writes tags to isolate work boundaries Second person independently verifies the scope of work and ensures the tags adequately isolate the work boundaries
“Hanging Tags” An officer verifies the tags and authorizes hanging the tags -> One person places valves, breakers, etc, in correct position and hangs tags Second person independently verifies that the tags are hung in the correct places and that the valves, breakers, etc, are in the correct positions Once work is complete and the system is restored, an officer authorizes the removal of the tags
