The Emergency Services Department (ESD) coordinates all professional emergency resources on the playa 24 hours a day, including requests to outside agencies via the state-of-the-art emergency dispatch center. ESD responsibilities cover all responses in the field to reports of fire, medical, or psychiatric emergencies. ESD's highly-trained professionals volunteer long hours to ensure the safety and well being of Black Rock City. ESD and LEAL (Law Enforcement Agency Liaison) together provide the primary interface between all outside health and safety agencies and the Burning Man Project, both on the playa and year-round.
