masa cuti ramai orang suka pergi pantai..walaupun seronok, kadang-kadang ada bahayanya juga.
baru-baru ni ada kawan yang terkena serangan
obor-obor. jadi nak share sikit info tentang obor-obor
atau jellyfish ni(dari wikipedia)
Ubur-ubur (juga dikenali sebagai ampai-ampai) merupakan haiwan yang tergolong dalam filum cnidaria, termasuk dalam kelas biologi skifozoa. Ia juga digunakan bagi merujuk kepada kelas biologi yang berkait dengan medusa (hidrozoa) dan ampai-ampai kotak (box jellyfish) (Cubozoa). Hampir kesemua ampai-ampai tinggal di laut dan walaupun mereka kekurangan struktur, organ mereka mempunyai ciri-ciri tisu khas
ini pula tentang bahayanya
The three goals of first aid for uncomplicated jellyfish stings involve preventing injury to rescuers, deactivating the nematocysts, and removing tentacles attached to the patient. Rescuers should wear barrier clothing, such as panty hose, wet suits or full-body sting-proof suits. Deactivating the nematocysts, or stinging cells, prevents further injection of venom.
Vinegar (3 to 10% aqueous acetic acid) is a common remedy to help with box jellyfish stings,[34][35] but not the stings of the Portuguese Man o' War (which is not a true jellyfish, but a colony).[34] For stings on or around the eyes, a towel dampened with vinegar is used to dab around the eyes, with care taken to avoid the eyeballs. Salt water is also used if vinegar is unavailable.[34][36] Fresh water is not used if the sting occurrs in salt water, as changes in tonicity[37] can release additional venom. Rubbing wounds, or using alcohol, spirits, ammonia, or urine have strongly negative effects as these also encourage the release of venom.[38]
Clearing the area of jelly, tentacles, and wetness further reduces nematocyst firing.[38] Shaving the affected skin with a knife edge, safety razor, or credit card can remove remaining nematocysts.[39]
Beyond initial first aid, antihistamines such as diphenhydramine (Benadryl) can control skin irritation (pruritus).[39] For removal of venom in the skin, a paste of baking soda and water can be applied with a cloth covering on the sting.[citation needed] In some cases it is necessary to reapply paste every 15–20 minutes. Ice or fresh water is not be applied to the sting, as this may help the nematocysts to continue releasing their toxin.[40][41]
In 2010 at a New Hampshire beach, pieces of a single dead lion's mane jellyfish stung between 125 and 150 people

tahukah anda? kata petua-petua lama, jika terkena sengat obor-obor atau sebarang binatang laut, dan luka kecil terpijak batu karang dsb, kencing di tempat terkena sengat/luka tersebut sebagai langkah first aid. betul atau tak? entah, tapi zaman muda dulu pernah gak buat, kasik lega sebelum rawatan selanjutnya.
