As most on here will have read, and I know Chris will confirm, I recently took in two re-homes that were part of a collection whose owner had pass away. The flame is very aggressive, striking at anything that moves past her line of sight. This is heightened at feeding time. So did some research into the matter and found that rubber washing up glove may well be the answer. Snakes apparently hate the taste of rubber. Recommended handling time is 1hr - 2hrs per week, this should desensitize the snake and hopefully deter it from biting. Well worth a try!
