The Presto "CB" Fire Extinguisher contained chlorobromomethane or "Halon" and could only be used in well ventilated areas. While a very good fire supressor, chlorobromomethane could cause cardiac arrest if inhaled. The use of chlorobromomethane was banned by the EPA in 2003 because it depleted the ozone layer.
