Standard Terminology Relating to Underwater Search, Rescue, and Recovery Activities (Withdrawn 2020)
SCOPE
1.1 The purpose of this terminology is to establish uniformity in terminology used in the field of underwater search, rescue, and recovery.
1.2 The terminology is appropriate to those underwater search, rescue, or recovery activities that use self-contained or surface-supplied underwater breathing apparatuses to provide a breathing gas supply for the searcher(s).
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
The purpose of this terminology was to establish uniformity in terminology used in the field of underwater search, rescue, and recovery.
Formerly under the jurisdiction of Committee F32 on Search and Rescue, this terminology was withdrawn in January 2020 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
