What is a Life Jacket?
A life jacket is a wearable buoyancy device designed to keep a person's head above water in emergencies. Filled with materials like foam or inflatable air chambers, it complies with international safety standards (e.g., ISO 12402) and provides critical time for rescue by preventing drowning.
Key Functions of Life Jackets
1. Airway Protection: Keeps mouth and nose above water to prevent choking.
2. Energy Conservation: Reduces physical exhaustion and slows hypothermia.
3. Visibility Enhancement**: Bright colors and reflective strips improve detection by rescuers.
Science-Based Selection Tips
Buoyancy Levels:
- Adult (150N+): For open water environments
- Child-specific (50-100N): Matched strictly by weight
- Design Types:
- Inherent buoyancy (foam): Most reliable, no inflation needed
- Inflatable: Compact but requires regular maintenance
Common Misconceptions
✘ "Inflatable jackets are always better"
✔ Foam jackets remain functional even when punctured
Evidence from Research
IMO data indicates:
- Proper use reduces drowning risk by 85%
- 90% of drowning victims were without life jackets
A certified life jacket is your ultimate survival tool, not just equipment. Always:
- Wear it properly at all times
- Check fastener integrity
- Supervise children continuously
