Communication, documentation, and human performance
Communication, documentation, and human performance
This domain tests whether you can transfer information accurately and leave an auditable record. It includes three-way communication, phonetics, procedure use, turnover, and error-prevention tools.
Core rules
- Use three-way communication: the sender states the message, the receiver repeats it, and the sender confirms. For critical actions, add independent verification.
- Use standard terms and phonetics for letters and numbers. Avoid pronouns and ambiguous words such as it or that valve.
- Document contemporaneously, with time, tag number, position, and name. A log entry is evidence; do not reconstruct it later from memory.
- Apply self-check and peer-check: pause, touch the correct component, compare the tag to the procedure, and verify the expected response.
Worked example
The command is Close 1CV-123. The operator repeats Close 1CV-123, the sender confirms, and the operator verifies the tag and closes the valve. The operator reports that 1CV-123 is closed and logs the time. If the valve will not move or the tag does not match, stop and report; do not substitute a nearby valve.
Traps
Accepting OK as a repeat-back; using left or right without a reference; logging after the shift; and skipping the peer-check because the task is familiar.
