Hawaii Beach Emergency Reference

Emergency contacts and source-aware context — not a treatment manual

🚨 EMERGENCY: CALL 911

For drowning, cardiac arrest, unconscious victim, anaphylaxis, or any life-threatening situation

Coast Guard (offshore): (808) 535-3333

This page provides general context only and does not provide medical treatment instructions. Always seek lifeguard, emergency, or professional medical care.

Rip Current — The #1 Killer

🌊 Someone is caught in a rip current

DO NOT swim directly out to rescue them — rip currents kill rescuers. Call 911 first.
1

Call 911 and alert the nearest lifeguard by waving both arms

2

Throw a flotation device — boogie board, life ring, cooler, anything that floats

3

Shout instructions: "Don't fight it! Swim sideways to shore!"

If YOU are in a rip: Stay calm. Swim parallel to shore (north or south) until you escape the current's pull. Then swim back diagonally. If exhausted, float on your back and signal for help.

Jellyfish Stings

🦌 Box Jellyfish & Portuguese Man-O-War

NOTE sting guidance differs by species, beach, and source. Ask a lifeguard or local first-aid provider rather than relying on a travel website.
1

Get local help from a lifeguard, first-aid station, emergency responder, or healthcare provider.

2

Expect source differences: vinegar, saltwater/seawater, heat, and cold are discussed differently across references.

3

Treat severe symptoms as urgent: chest pain, breathing trouble, faintness, or face/throat swelling.

Call 911 for chest pain, shortness of breath, face/throat swelling, faintness, extreme pain, or loss of consciousness.

Sea Urchin (Wana) Punctures

🦚 Wana Spines in Foot or Hand

NOTE brittle spines, deep punctures, joints, and eyes are reasons to involve a healthcare provider.
1

Ask local help from a lifeguard, clinic, urgent care, or doctor.

2

Know what sources mention: warm water and vinegar appear in some Hawaii safety materials, but this site does not tell you to use them.

3

Watch for infection concerns: increasing redness, warmth, swelling, pus, fever, or worsening pain.

Spines near joints or in eyes require medical care.

Coral Cuts

🪸 Coral Laceration

DO NOT ignore coral cuts — they carry Vibrio bacteria and infect rapidly.
1

Scrub thoroughly with a brush and antiseptic soap under running fresh water for 5+ minutes

2

Remove coral fragments with sterilized tweezers — any remaining debris will cause infection

3

Apply antiseptic — hydrogen peroxide or povidone-iodine solution

4

Cover loosely — do not seal tightly; wounds need to drain

5

See a doctor if the wound is deep, shows red streaking, or if you develop fever

Heat Emergencies

Heat Exhaustion

Heavy sweating, weakness, cool/clammy skin, nausea, headache. Action: Move to shade, cool wet cloths, sip water slowly. Monitor — if they stop sweating or become confused, call 911.

Heat Stroke 🚨

High body temp, hot DRY skin, confusion, rapid pulse. Call 911 immediately. Cool aggressively with water, ice packs to neck/armpits/groin while waiting for EMS.

Drowning / Near-Drowning
Call 911 immediately for any near-drowning — even if the person seems fine. Secondary drowning can occur hours later.
1

Do NOT enter the water unless trained in water rescue. Throw a flotation device.

2

If victim is out of water and unresponsive — check breathing. Begin CPR if not breathing.

3

Do NOT perform the "Heimlich maneuver" for drowning — it delays CPR and is ineffective for water removal.

4

Keep victim warm — wet victims lose heat rapidly. Cover with towel or clothing.

5

Even if the victim recovers and seems okay — still go to the ER. Secondary drowning is real.
