What to do IF bitten (and that's a big if),
1. Slowly move away from anyone with an extractor or snake bite kit.
2. Situational Awareness, if you can get to a medical facility, then proceed with all due haste.
3. If you can't take heart that few snake bites need medical attention, problem is you're unlikely to know if you need medical attention immediately after a bite, hence get to a medical facility if possible.
4. If it takes a long time to get to a medical facility then by the time you get there you'll know if you need anti-venom, so don't panic if nothing seems to be happening, there probably wasn't any venom injected. When you get to a medical facility have them clean the wound for possible infections.
5. The following website is the only site that I've seen that offers good advise besides get to a hospital. It's well stated and I'll not restate if as they've done an excellent job.

Lastly, I talked to many ER doctors and they generally state that mostly they don't need to treat snake bits, beyond possible infections, as few have venom injected.
