History and Evolution of Life Buoys
Lifebuoys have been used for centuries to save lives at sea. The term “life buoy” primarily appeared in 1783. However, the concept of a ring-shaped flotation device dates back further. Leonardo da Vinci first sketched a safety wheel concept, which is similar to today’s lifebyou ring.
While early versions were simple flotation devices made of cork or wood, they laid the foundation for modern safety equipment. By the late 18th century, ships commonly carried life buoys as a basic rescue tool. Over time, their design improved with stronger materials and better buoyancy.
As maritime travel increased, so did the need for more effective life-saving equipment. By the 20th century, life buoys were standardized with bright colours for visibility and lightweight designs for easy handling. The addition of grab lines around the ring made it easier for a person in distress to hold on.
Today’s life buoys are far more advanced. Many are made of durable, weather-resistant materials like polyethylene foam. Some are equipped with reflective tape and high-visibility colors to make them easy to spot in low light.
Others contain built-in emergency lights, whistles, or GPS beacons to help rescuers locate people faster. On large ships, automatic release mechanisms help life buoys deploy instantly when needed. These advancements have made lifebuoys more effective and accessible.
Types and Designs of Life Buoys
Lifebuoys come in various types and designs, each tailored to specific environments and purposes.

Some life buoys are designed for specific industries, such as offshore oil rigs or naval vessels. These specialized designs may consist of features like increased durability, integrated lights, or locator beacons to meet the unique safety requirements of their operational environments.
Importance of Life Buoys in Human Health
Lifebuoys are vital in safeguarding human safety in aquatic environments. Their presence is crucial in various settings, like pools, beaches, and ships, serving as a frontline defense against drowning which is a significant global health concern.
Drowning ranks as the third leading cause of unintentional injury death worldwide, accounting for 7% of all injury-related fatalities. The World Health Organization estimates that approximately 236,000 people die from drowning annually. This alarming statistic underscores the necessity of preventive measures, such as the availability and proper use of lifebuoys, to mitigate the risk of drowning incidents.
Other than drowning, life buoys also play a crucial role in reducing injuries and illnesses associated with water exposure. For instance, wearing a life jacket can provide thermal protection against hypothermia, a dangerous drop in body temperature due to prolonged exposure to cold water.
The importance of lifebuoys is particularly pronounced in regions with high rates of water-related accidents. Over 90% of drowning deaths occur in low- and middle-income countries, with children under the age of five at the highest risk.
Implementing safety measures, such as the widespread availability of lifebuoys, is essential in these areas to enhance water safety and protect vulnerable populations.
Lifebuoy Brand Safety and Regulations
Lifebuoys are crucial for maritime safety, and their design and maintenance are governed by international regulations. The International Maritime Organization (IMO) sets these standards through the International Convention for the Safety of Life at Sea (SOLAS). Maritime customers value these strict standards.
According to SOLAS, life buoys must adhere to specific design criteria to ensure effectiveness:
- Dimensions: Each life buoy, measured in units, should have an outer diameter no greater than 800 mm and an inner diameter of at least 400 mm.
- Materials: They must be constructed from inherently buoyant materials, avoiding reliance on materials like cork shavings or any air compartments that require inflation. Advanced models may come with integrated batteries.
- Lifelines: At least one lifebuoy on each side of a ship must be equipped with a buoyant lifeline. The length of this line should be at least twice the height from which it is stowed above the waterline in the lightest seagoing condition or 30 meters, whichever is greater.
