In a reversal of position and form to what was previously reported by ASW (link), on 30 May the FAA decided that it would provide specially enhanced weather radios to "selected" control towers. These radios broadcast only alert messages for local severe weather. In the same news release there's an admission to "having had several unfortunate environmental incidents at some of our air traffic facilities". This is an oblique reference to controllers being forced to remain seated during a 25 April carbon monoxide (CO) poisoning event at the New York terminal radar approach control (TRACON) facility and one seven days later that caused an evacuation of air traffic controllers from Washington's Dulles Airport tower. The Dulles incident came just two months after a botched roofing project and a badly delayed and ineffective cleanup effort at Jacksonville TRACON resulted in employees having to breathe toxic odors. Five controllers are still out and being treated by the Mayo Clinic. U.S. Senator Charles Schumer blasted the FAA for ignoring the need for CO detectors in air traffic control towers, so now they're to be installed also ("we will be purchasing and deploying over 60 portable air quality meters capable of detecting volatile organic compounds and four types of gases"). In the NY incident controllers were required to direct air traffic while struggling to remain awake for up to four hours. They were later treated for CO poisoning but the case was dismissed as a "once off". In both CO cases, the poisonous gas was inadvertently allowed into the work-spaces by works in progress, and no alarms were present to alert the workers that they were inhaling toxic fumes. According to the National Air Traffic Controllers Association, none of the 29 TRACON or 314 FAA facilities have central carbon monoxide alarm systems to sound alerts. Sen Schumer sent a letter to the Senate Commerce Committee requesting that a provision requiring the FAA to install carbon monoxide alarms in all FAA Air Traffic Control facilities be inserted in this year's FAA reauthorization bill.
