Once at medical facility, stay there until relatives of injured person have been contacted. If you see or hear a rattlesnake . . In the history of California State University, University of California, community colleges, and private institutions, there has never been a recorded case of snakebite in the field. Hardly anybody dies from snakebite. Sit down and relax. . .
Most snakes are non-poisonous.
Leave the snake alone. If possible, cool bite area with water, but do not freeze, to slow circulation. Do not attempt any first aid. If with a companion, send them for help, sit quietly. If alone, walk slowly to transportation and take yourself to a hospital.
