Problem With Mustang Inflatable PFD's. The Coast Guard has become aware of certain Mustang Survival Inflatable PFDs with Hammar MA1 hydrostatic (HIT) inflation systems which may not inflate and require a new re-arm kit to properly inflate by manual or automatic activation. This safety alert identifies which products are affected. Certain inflatable PDFs may be subject to delayed or non-inflations. To determine if you are impacted please follow the instructions below. If you have a re-arm kit MA7214 or MA7218 you need only to check the lot number on the CO2 cylinder label.

SAFETY ALERT – Inflatable lifejackets equipped with Hammar Hydrostatic Inflator manufactured before 2006. This Safety Alert was recently distributed to shipping authorities and advertised in the trade press, boating magazines and digital media worldwide. The Hammar Hydrostatic Inflator is attached to the lifejacket with a sealing ring. In 2006, CM Hammar upgraded the sealing ring with new state of the art raw materials, to eliminate potential defects and increase long term durability. A small number of sealing rings manufactured before 2006 have suffered premature material degradation, most likely after being exposed to extreme environmental conditions.

CM Hammar, of Göteborg, Sweden announced that fake copies of their Hydrostatic Release Unit, the Hammar H20, are being produced, posing a serious safety hazard. The copy is almost identical to the original product, with Hammar’s logo and address on the labels, however, the fake does not work. Hammar tested several of the copies. Not one of them worked properly according to SOLAS’ specification. The fake H20 will not release a life raft or an Epirb. Hammar stated that they see this as a very serious situation. There could be a number of ships at sea that are sailing with fake Hydrostatic Release Units. If any of these ships were to sink, there will be no life rafts or Epirbs to help to rescue the seafarers in danger.

The Hydrostatic Release Unit from Sweden is found life rafts and EPIRBs of all sizes and on all types of ships around the world. The new Hydrostatic Release Unit, with the same name as its predecessor H20, has been introduced. The H20 is designed for easier installation. It has a 3-step coupling device that eliminates the risk of incorrect installation. The Weak Linkä of Hammar is now integrated into a new black thimble. This gives smaller tolerances in the Weak Linkä system (breaking strength 2,2 +/- 0,4 kN) as well as a stronger lower thimble construction. For the end user, the new design will be noticed in first place by the clear and easy-to-understand installation.
