Larry McLouth raises a significant issue about testing. Safety eyewashes and showers need to be activated periodically and extensively checked annually. Poor drainage arrangements can cause people to either dry lab the activations or do the activations in a perfunctory manner that does not catch flow balance and pattern problems for eyewashes because the testers don't want to clean up the mess. Drainage arrangements need to be designed in. That may mean the drain stub of an eyewash ends at the height of a carboy on a cart instead of three- or six-inches above the floor where environmental requirements, etc. preclude using a floor drain. There are shower curtain and garbage can test kits (with carts) for safety showers. Water is heavy so arrangements need to be made, hopefully in advance, to safely handle the collected test water before someone is injured. Even eyewash activations, if they last long enough for the tester to see the eyewash flow pattern, leave a lot of water to be carried off somewhere.
