Graystone Park Fire Department provides fire protection and prevention to Graystone Park Psychiatric Hospital. Graystone Park is a 550 bed 460,000-sq.-ft., 3-story facility with short and long-term patients. Graystone Park Fire Department is a full time department with 7 full time firefighters and 3 apparatus. The department responds to all calls within the facility's ground with mutual aid from Parsippany and Port Morris fire departments, as it borders both towns. Due to the small size of the department, it only provides limited mutual aid to nearby communities. In addition to responding to emergency calls, they also provide fire prevention to the facility.
