Emergency! S03E07 - The Promotion

Roy passes the Engineer's exam, but since accepting the promotion would mean leaving the paramedics–and John, he talks over his decision with Drs. Brackett and Early. The firefighters handle a fog-caused multi-vehicle accident on the San Diego Freeway, resulting in numerous deaths and injuries, including one man with a heart murmur, whom Dixie and Dr. Early help in treating. The paramedics attempt to assist an attempted suicide (by taking six aspirin tablets) but are sent to a vacant lot instead; when they find the right location, they end up in the middle of a domestic dispute. John and a security guard are injured in a fire and Roy has to rescue both of them.
