Rescue services meet the SOLAS Convention, the IMO standards, has watertight, natural insulation and buoyancy function Since lifejacket lights and equipped with whistles, not wear a lifejacket. It underwear fused, outside the protection of the entire body except the face, apply to all ships navigation. oil platforms and other marine engineering operations. The product type approval and testing by the China Classification Society. 0 -2 ° C temperature insulating properties thesis in calm water flow lasted six hours, not more than 2 ° C lower temperature. Buoyancy than 142N, immersed in the water 24 hours after the loss is less than 5% of its buoyancy. A new refrigeration insulation weighing 5 ± 1 Introduction rescue service. Have the buoyancy. - soaking the insulation is no need to wear a life jacket insulation services. Using quality fabrics chloroprene rubber (NEOPRENE), waterproof, insulating, high temperature resistance, flame retardance, oil resistance and the strength of multi-storey complex, non-toxic, non-irritating odor, not the sea air, water, fresh water, and the impact of the use of oil and fungi. 2. The insulation type insulation rescue service has passed the quality test equipment rescue ship classification societies -- Wuhan strict testing center Georgia test (the test center for gifted and has been CCS, EC, and other major classification societies recognized BV) full compliance with the International Maritime Organization (IMO) : ILS equipment rules (LSA) and the International Rescue Equipment Test MSC.81 (70), CCS has been made, the EC certificate. 1 properties, waterproofing in water for about one hour later : thesis, the water level is less than 200g of clothes (only 20-40 g); evaluates the body from where it all into the water and jumped into the high water. the water level is less than 500g (about 140-160 g). 2, buoyant performance : 5 seconds thesis can be turned over to face upward in the gesture, the Ministry of mouth emerges from the water 120 mm, After soaking in water for 24 hours, its buoyancy loss is less than 5%. 3, the thermal insulation characteristics : evaluates the static water soaked 0 -2 ° C for six hours lower temperature less than 2 ° C (0.6 ° C lower only), hands, enough skin temperature no less than 10 ° C (18 ° C in the minimum temperature above).
