Safety Summary
STANDARD NAVY SYNTAX
Since this manual will form the technical basis of many subsequent instructions or directives,
it utilizes the standard Navy syntax as pertains to permissive, advisory, and mandatory
language. This is done to facilitate the use of the information provided herein as a reference
for issuing Fleet Directives. The concept of word usage and intended meaning that has been
adhered to in preparing this manual is as follows:
“Shall” has been used only when application of a procedure is mandatory.
“Should” has been used only when application of a procedure is recommended.
“May” and “need not” have been used only when application of a procedure is discretionary.
“Will” has been used only to indicate futurity; never to indicate any degree of requirement for
application of a procedure.
The usage of other words has been checked against other standard nautical and naval termi-
nology references.
