solas approved inflatable life jacket

275N SOLAS lifejacket/lifevest with advanced technology according to ISO 12402-2 (CE-Sign). The special model for working at height locations: The most durable lifejacket/lifevest offers in combination with fall protection and distress transmitter matched, a tested and certified PSA system.

The belt guide at the covers bottom, the reinforced, split back belt, the highly stable click buckle with integrated adjustment - these are the features of this work vest. They are crucial to ensure that the lifejacket/lifevest can be safely adapted to a fall protection system. Both elements of the personal protective equipment complement one another and function reliably as a combined system. Especially in locations such as offshore wind farms or at rescue from heights the compact form of the lifejacket is important to ensure the necessary freedom of movement. 

All fall arrest attachment points are fast and safe reachable. An integrated PLB is visible through an inspection window from the outside and is placed by the 3D buoancy chamber in an emergency at the highest possible point in order to allow optimal radiation performance. The coated outer fabric of the protection cover is highly tear and abrasion resistant, making it suitable for hard labor. 


  • cover: 
    Through the SECUMAR-window the function check is now easier than ever. Through a window in the cover it is always seen from outside at a glance whether the inflator and the EPIRB are in ready to use condition. The donning and doffing is particularly easy by the patented click front-fitting. Around the vest as a jacket and close the front-fitting as with the seat belt. Even with gloves this fitting is easy to use. 
    By additional belt guides the lifejacket can be connected to a fall arrest and thereby don and doff together. 
  • buoyancy chamber: 
    With the new patented 3D buoyancy chamber design an exceptional turning effect is achieved even with heavy clothing. In addition, the float in the inflated state is characterized by a very high level of comfort. By the three-dimensional design, the visibility of the wearer in the water increased significantly and allows the installation of a dedicated light at the highest point of the buoyancy chamber and approximately 20 cm higher than traditional life jackets. Also, the PLB gets a significantly improved range in this position 
  • inflator: 
    1st Chamber: A red-green indicator for all four necessary conditions: SECUMAR Pill Box inserted, CO2 cartridge full, CO2 cartridge installed properly and locked trigger. 
    2nd Chamber: A red-green indicator for all necessary conditions: CO2 cartridge full, CO2 cartridge installed properly and locked trigger. 
  • configuration: 
    A soft neckfleece ensures a comfortable fit in the neck. It is removable, washable and replaceable at any time. 
    The service tag on the waist belt shows you at a glance when your lifejacket should be serviced again in SECUMAR service.

Lifejackets need a service too

Where the safety of peoples’ lives is concerned, regular inspection of the equipment concerned is absolutely essential. This also applies to lifejackets. Natural aging process can influence the properties of the material and also the functioning of the automatic inflator system is not immune to possible damage (among other things operational errors). In other words: the life of a lifejacket must be limited. The corresponding time frame has been set at 10 years, a decision borne authoritatively by the members of the German Association for Sea Rescue Equipment (FSR), and which complies with the law of safety and product liability.

A prerequisite for this lifetime is an inspection of the lifejacket by an authorized servicing station or the manufacturer at least every two years.

Safety as a visible sign

Regular inspection is documented by the FSR-Service-Sticker, which, similarly to a car’s MOT sticker, signalizes the month and year of the next service due.


The regular system check by the expert comprises testing the buoyancy chamber for air leaks as well as a scrutinizing check of the fully automatic inflation system. Moreover, within the framework of this SERVICE we can offer:

  • Repair
    Removal of any defects discovered in the course of the inspection as well as replacement of the complete protective cover or buoyancy chamber.
  • Conversion / Optional extras
    Converting from manual release to automatic inflation, adding a spray hood, installation of an emergency light and further signalling accessories.

Receipt of the new FSR-Service-Sticker confirms, so to speak, the correct functioning of the rescue equipment and always reminds you of the Date of the next inspection, the sticker being clearly visible from the outside.
