The purpose of this document is to explain the contents and operation of the Safety Management element of MOD’s Acquisition Safety and Environmental Management System (ASEMS). This element is known as the Project-Oriented Safety Management System (POSMS). The other element of ASEMS is the Project-Oriented Environmental Management System (POEMS) which has a separate, although closely related, manual.

The first link in the list of documents below is the POSMS Manual, which includes all Core Procedures (SMP01 - SMP13), Support Procedures (SSP01 - SSP03), and Assurance and Audit Procedures (AAP01 - AAP04). The rest of the links are the individual documents that form the POSMS Manual, included here for ease of navigation.
