The bladder for this lifejacket positions both inflation mechanisms on one side to comfortably accommodate the sMRT PLB on the other. This, combined with the ergonomic Fusion 3D cover, results in a balanced and symmetrical profile to improve overall constant-wear comfort - leaving your workforce unhindered to move, work and perform.

Inspection zips have also been incorporated to each side of the lifejacket - allowing the sMRT PLB to be turned on/off and the inflation mechanisms to be checked without entirely opening the lifejacket. This allows personnel to take ownership of inspecting their inflation mechanisms before donning the lifejacket, to ensure the unit is action ready.

What is the difference between a lifejacket and a buoyancy aid?

Although both are called personal flotation devices (PFDs) they are quite different. A lifejacket is designed to support the wearer in the water and will rotate them into a face up position - even when unconscious. Lifejackets offer more buoyancy, which helps to increase the distance between the waterline and the airway. Buoyancy aids are not designed to fully support the wearer in the water face up, but to provide buoyancy to help support the wearer in the water and reduce fatigue. Lifejackets are designed for swimmers and non-swimmers alike whilst buoyancy aids should only be worn by competent swimmers.

Do I need to service my lifejacket?

As a lifejacket manufacturer we would always recommend an annual service, however depending on your operation and the approval authority you are governed by it may also be a legal requirement.

Safety of Life At Sea (SOLAS) – If you are operating under SOLAS, professional lifejacket servicing is a legal requirement and must be performed annually.
ISO – The MCA state that the owner should follow the manufactures guidelines for servicing, in this case this means performing a professional service annually.

What standard components of an inflatable lifejacket have expiry dates?

Automatic capsule – Located on automatic lifejackets. 3 years from manufacture. Replace component as per the date shown or if it has been fired
Hydrostatic capsule – Located on automatic lifejackets. 5 years from manufacture. Replace component as per the date shown or if it has been fired
Surface light – 5 years from manufacture. Replace component as per the date shown or if it has been activated for an extended period of time
Cylinder – No expiry date, only change once used or if there is sign of damage or corrosion. Ensure there is no corrosion on the thread or main body of the cylinder.

Will my lifejacket automatically inflate when I fall in the water?

This is dependent on your lifejacket. Some lifejackets are designed to be manually activated only. Always make sure you know what type you’re wearing and if it is suitable for the activity. All inflatable gas lifejackets will come with a manual override, make sure you know where this is and that it is accessible.
