When bitten by a snake, you should do these things first — Page 4

Do seek medical help immediately as the venom can cause severe damage to health or even death within a few hours.
Do NOT allow the victim to walk or move their limbs. Use a splint or sling to minimize all limb movement. Put the patient on a stretcher or bring transportation to the patient.
Do NOT incise or cut the bite or apply a high tourniquet. Cutting or incising the bite won’t help. High tourniquets are ineffective and can be fatal if released or result in the loss of a limb.
Do bandage firmly, splint, and immobilise to stop the spread of venom. To slow the spread of venom, major medical associations recommend placing a folded pad over the bite area. Then apply a firm bandage to wrap the entire limb, from bottom to top. It should not stop blood flow to the limb or congest the veins. Only remove the bandage in a medical facility, as the release of pressure will cause a rapid flow of venom through the bloodstream.
Do NOT wash the area of the bite or try to suck out the venom. It is extremely important to retain traces of venom for use with venom identification kits.
