The typical work environment of an EMT includes some risks, such as responding to car accidents on a busy highway or providing care to people in the aftermath of a natural disaster. High-stress situations can also put an EMT in perilous situations. An EMT, for example, may have to deal with someone who has a history of violence. EMTs may also come into contact with environmental or chemical toxins and various communicable diseases. EMT training includes a safety component that teaches you how to take the necessary precautions to keep yourself, your coworkers, and the people you're caring for safe.
