WASHINGTON (AP) - Safety officials are warning about the risk of a potentially deadly release of chlorine gas unless the government requires equipment for transporting it.
A safety bulletin Thursday from the U.S. Chemical Safety and Hazard Investigation Board recommends that sites where rail cars unload chlorine have automatic shut-off valves and other devices that can stop the flow of gas in an emergency.
A board survey found that 30 percent of water treatment plants lack the most effective equipment to detect and stop chlorine leaks. That leaves the public vulnerable to large-scale releases.
