Rescue clubs and ambulance foundations most often serve communities with volunteers to respond to emergencies with ambulances and other rescue resources. Most foundations and clubs request volunteers to acquire at least the Emergency Medical Responder level of training. Most EMR level units use pickup trucks with elevated caps to respond to emergencies. These vehicles usually are marked with the association name and seal along with lighting and sirens. Units at this level act as the first arriving responders, and must do much to stabilize the scene for other units, such as Advanced Life Support (ALS), to arrive. EMR units often transport patients to medical treatment facilities especially for basic level patients and when ALS units are unavailable. EMRs coordinate with firefighters, police, and other medical professionals in emergency situations.
