prepared with guidance and direction from the API Security Committee, to

Facility Security Plan (FSP). This standard specifies the requirements for
preparing an FSP as well as a discussion of the typical elements included in
an FSP.
This standard is intended to be flexible and adaptable to the needs of the
user. It is noted that the content of an FSP can vary depending on
circumstances such as facility size, location, and operations. This
methodology is one approach for preparing an FSP at petroleum and
petrochemical facilities. There are other security plan formats available for
the industry. It is the responsibility of the user to choose the format and
content of the FSP that best meets the needs of a specific facility. The format
and content of some FSPs should be dictated by government regulations for
covered facilities. This standard is not intended to supersede the
requirements of any regulated facility but may be used as a reference
