Quick Answer
Exposure to saltwater can cause dehydration, electrolyte imbalance, and skin irritation due to the high salt concentration. Prolonged exposure can lead to saltwater poisoning, which can be fatal if not treated promptly. Exposure can also increase the risk of shark and other marine animal attacks.
Saltwater Exposure Risks and Treatment
When exposed to saltwater, it’s essential to rinse the affected area with fresh water as soon as possible to prevent skin irritation and electrolyte imbalances. If you’re unable to access fresh water, use a mixture of 1:1 ratio of water to urine to help neutralize the salt. Apply a topical antibiotic ointment to prevent infection.
Prevention and Emergency Preparedness
To prevent saltwater exposure in life raft situations, wear protective clothing such as long-sleeved shirts and pants, and apply a waterproof sunscreen to prevent skin irritation. If you’re caught in a storm or rough seas, secure any loose items on the life raft to prevent them from becoming projectiles. In emergency situations, use a desalination device or a solar still to obtain fresh water, and consume only the minimum amount of saltwater necessary to stay hydrated.
Signaling for Rescue
If you’re stranded at sea, signal for rescue by creating a smoke signal during the day and using a flare or mirror at night. Use a life raft’s built-in signaling devices, such as a radio or EPIRB (Emergency Position Indicating Radio Beacon), to send a distress signal to nearby vessels. Wear a brightly colored or reflective vest to increase visibility from a distance.
