Radio Iowa: As many as 15,000 Iowans who work in some 350 hotels and motels statewide are being issued employee safety devices, or ESDs, as part of a program designed to help keep them safe while on the job. The American Hotel and Lodging Association is supplying guides to the hand-held ESDs so each hotel can buy the type of device that’s the best fit for that property. Features range from a simple loud alarm to a GPS tracking system.
