When I teach Emergency Response courses at fixed facilities I encourage the facility to use their safety showers as their first stage (and often the only stage) of decontamination during an emergency response. For years, fixed facility personnel attended HAZMAT training with local fire departments where they were taught the traditional 4-6 stage decon line with all the dressings (e.g. baby pools, booms, plastic, etc.) But there is a VAST difference between a decon on a city street and at a fixed facility; but there should be some careful considerations when using a safety shower as a the first stage of decon.
