While areas in the Southeast U.S. experience the aftermath of Hurricane Irma, the Centers for Disease Control and Prevention has shared a number of resources, including how to prevent carbon monoxide poisoning – one of the main causes of death after a hurricane. “Always use generators, pressure washers, and any gasoline-powered engines outdoors, at least 20 feet from doors, windows, and vents,” CDC says. In addition, the agency has shared other tips for being safe after a hurricane, including being careful near damaged buildings and staying away from power lines and dangerous materials. Irma made landfall Sunday in southwestern Florida, and millions of residents in the state remain without power.
