"The Office of Emergency Response (OER) is Rhode Island's first line of defense in protecting public health, safety, and welfare in an environmental emergency. Like police officers and firefighters, DEM's emergency responders are prepared to handle a great variety of incidents. These incidents may range from a spill of a few gallons to a petroleum tanker rollover, an abandoned drum to bioterror weaponry, and many other possible threats to environmental and public wellbeing. Highly trained first responders are on-call 24 hours a day and 7 days a week. They are tasked with responding to and remediating incidents posing imminent dangers."
