Found this : Any snake measuring over 13 or 14 feet should probably be worked with a partner. *Someone that has large snake experience would be an obvious benefit, but even someone with no experience watching your back is safer than working alone. *You should always mention to your “spotter” a few things. *If a snake actually wraps you up in an attempt to constrict you, it is always best to unwrap the snake starting from the tail. *Trying to pull coils off in its mid section or trying to push coils to the side in an attempt to pry off the head would likely be futile. *It is a good idea to keep a spray bottle of alcohol such as vodka handy. *Sometimes simply spraying an alcoholic substance in the snake’s mouth will cause them to release their bite. *As with any medical emergency, the victim’s airway and breathing status should always be the first priority. **Stopping the snake from constricting a person’s chest, neck or head is much more important than stopping a bite to an arm or leg. *Dialing 911 is of course a good idea, but you have to remember that A. seconds count if someone is being constricted and B. keeping large snakes is a specialized area of expertise. *Paramedics aren’t trained in removing 19-foot retics from people. *It is your responsibility to know what to do, and have your back up know what to do too. *
