Carbon monoxide monitors will be installed in all Baltimore schools

From The Baltimore Sun: The Baltimore city school system will place carbon monoxide detectors in all of its approximately 200 schools after two potentially deadly exposures occurred at the same school. The first 35 battery-powered detectors, which wholesale for $15 each, will be installed within a week at schools that have the same type of oven equipment identified as the source exposure at Dickey Hill Elementary/Middle School. A district spokeswoman says the incidents at the school show how the problems that stem from aging buildings and equipment.
