"This Guide is intended for working interpreters, interpreting students and educators, and those who employ or purchase the services of interpreters. Occupational health education is essential for professionals in training, to avoid early attrition from practice. "Sign language interpreting" is considered to include interpretation between American Sign Language (ASL) and English, other spoken languages and corresponding sign languages, and between sign languages (e.g., Deaf Interpreters). Some of the occupational health issues may also apply equally to Communication Access Realtime Translation (CART) reporters, oral interpreters, and intervenors. The reader is encouraged to make as much use as possible of the information provided here". -- Introduction.
