ISO Jackets

ISO - 12402, lifejackets are made to the ISO standard and therefore should all be made to the same standard or quality. That said there are some clear difference in types of jackets. There are also various types of manual and automatic jackets which are explained below.

Manual jackets
This type of jacket requires manual inflation by pulling down or sideways (depending on the jacket) to inflate. These are fine if the vessel you are working / sailing on, is particularly wet but it would not be our choice. The only time these are a good idea is when used on an aircraft. 


Auto Lifejackets
There are various types of auto systems. Some companies such as Lalizas have their own type of inflation system which does keep the cost down. Other makes, use one of these types:

United Molders - These are normally black cartridges that screw onto the bottom of the operating head on the lifejacket. These are sprung loaded and water activated. These have one of the longest replace by dates.

Halkey Roberts - These are small yellow salt capsules that sit in a clear bowl at the bottom of the ophead. These typically have 2 years for leisure and annual for commercial

Hammar - These work on water pressure and hydrostatic. These are great if you work on a particularly wet vessel. They only go off when the 30cm - 1m in the water. Spray does not set them off
