It must be ascertained that the hose assembly:\n(1) Has no loose covers, kinks, bulges, soft spots, and no gouges, cuts, or slashes that penetrate any hose reinforcement;\n(2) Has no external and, to the extent internal inspection is possible with both ends of the hose open, no internal deterioration; and\n(3) Does not burst, bulge, leak, or abnormally distort under static liquid pressure at least as great as the recommended working pressure.","path":["Title 46—Shipping","CHAPTER I—COAST GUARD, DEPARTMENT OF HOMELAND SECURITY","SUBCHAPTER O—CERTAIN BULK DANGEROUS CARGOES","PART 153—SHIPS CARRYING BULK LIQUID, LIQUEFIED GAS, OR COMPRESSED GAS HAZARDOUS MATERIALS","Subpart C—Operations"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-46.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:22Z","sha256":"2886b5fd3b54abc3123e84b496e1ccda01d56f2d435b166a918be7753603b27f","source_id":"us-cfr","stale":true,"prev":"us/46-cfr-153.936","next":"us/46-cfr-153.953"},"notice":"GroundRules: Original legal text.
