Approval Record
Stearns’ certification library links the I600 to Type I certificate 160.055/187/0 (archival PDF). That copy expired May 24, 2025. It documents the model and adult fit range, but does not prove current production approval. Confirm supplied inventory and applicable vessel requirements before issue.
Selection and Inspection
For shipyard use, review OSHA 1915.158 for PFD approval, marking and inspection requirements. A Type I design aims to turn most unconscious wearers face-up; fit and conditions still matter. The back opening is not a fall-arrest attachment. SOLAS-grade reflective trim does not establish SOLAS approval of the entire lifejacket.
Ordering an Existing Specification
Provide the item number, label information and required adult fit when matching vessel inventory. Check condition, closure operation and compatibility with other equipment before use. Availability must be confirmed separately from this description.

FAQ
Is the manufacturer certificate current?
The linked manufacturer-hosted copy is archival. Its expiration does not by itself determine whether a particular older vest remains serviceable; inspect the unit and verify its label and applicable requirements.
Does this vest include a harness?
No. A back opening does not supply or certify a fall-protection harness.
