US Coast Guard: Immersion Suit Maintenance and Inspections

U.S. Coast Guard (USCG) inspectors frequently find immersion suit defects caused by adhesivef ailures between the main zipper and the suit body. These failures, illustrated in the images, compromise watertight integrity and pose serious survival risks from water ingress. Contributing factors to the defects include improper maintenance (e.g., the use of non-approved petroleum based lubricants or scented powders), improper storage, and neglecting to conduct periodic pressure testing. Seam and closure deterioration may not always be detectable during routine visual inspections. Adhering to USCG regulations, manufacturer instructions, International Maritime Organization (IMO) regulations and guidance, and performing regular inspections and testing are essential to ensuring immersion suit reliability.
