The South African Marine Safety Authority (SAMSA) specifies a set of requirements for life jackets
that must be met in order to receive the SAMSA approval. These requirements cover circumstances
that occur at sea, in extreme offshore environments, inland, and near to shore.
A life jacket rated at level 275 is essential for usage in waters with harsh circumstances because it
offers sufficient buoyancy to assist users who are also wearing additional garments or weights. It is
intended to maintain the wearer in the proper position, ensuring that their mouth and nose remain
above the surface of the water at all times.
Life jackets of the Level 150 variety are intended for use in a variety of maritime contexts, including
those in which the wearer is outfitted with multiple layers of clothing for use in severe
environments. When the wearer loses consciousness, the jacket should place them in a secure
posture automatically. At this level, there is the potential for a rapid rescue to take place in placid or
protected seas. The head of the wearer should be supported by the jacket, and an unconscious
person should be turned over onto their stomach.
Level 50 is for usage only by experienced swimmers in inland water and has restrictions on where it
can be utilized. This life jacket is perfect for activities such as water-skiing, jet skiing, yachting,
canoeing, and other similar water sports.
