What is the primary purpose of the Pre-survey Outline Booklet (PSOB)?

The primary purpose of the Pre-survey Outline Booklet (PSOB) is to serve as a foundation for initial certification and recertification of diver life support systems. This booklet outlines the essential requirements and standards that must be met for systems to ensure safety and operational effectiveness in diving operations. It provides a comprehensive approach to evaluating the DLSS, including system design, operational procedures, and maintenance practices that are critical for achieving certification.

The PSOB is utilized by certifying bodies to assess whether the systems meet the necessary criteria and to help ensure that divers are using well-maintained and compliant equipment. By providing a structured outline, the PSOB facilitates the consistency and integrity of the certification process, thus promoting safe diving practices and supporting the overall safety of divers.

While it may have relevance to maintenance technicians and documentation for compliance, those aspects are secondary to its primary role in the certification process. The PSOB is not explicitly a training manual for divers, though it may indirectly support their training by ensuring that the standards of the life support systems are up to par.
