Lets see... precautions to take:
(a) Wear a full 3/2 wetsuit that firmly covers all of your appendages.
(b) If cold sensitive, consider a hood. It could stop all your brains from leaking out and a funky piranha/mickey mouse hood could makes you a lot more visible to your DMs/buddies.
(c) Don't touch ANYTHING. That includes anemonies, coral, fishies, manta rays, mimic octopus and especially sharks. PG water is too warm for gloves but be cautious around descent ropes and the strange structures in Sabang wrecks or at the Tropicana.
(d) Remember jellyfish tentacles remain stinging even after being severed from the jelly. I suspect that was what got my face scarred during that dive. Not the ensuing acid attack from a jealous woman at the Point.
(e) Don't rest/sit/mediate on the sand. Without checking to see if there is someone else there first. My buddy saved me from a potential Steve Irwin incident when I was settling down to avoid currents and really pissed off a blue spotted ray snoozing on the seabed next to the Dona Marilyn wreck. Needless to say, look carefully before you lie down on it/her/him.
(f) If stung, seek immediate assistance. Coral cuts are very nasty esp fire coral.
A good DM will be able to advise if you should wash the wound with vinegar(for jellyfish) or pee pee (for stingray). Found a whole series of medical articles to read up for
diving-related injuries. There is a separate section of communicable diseases that may be contracted in Centrum in Sabang or White Beach.
