EHS tests showers and eyewashes every six months in laboratory areas to certify that water pressure and flow rate are within acceptable parameters.
In addition, departments are required to flush safety showers and eyewashes every two weeks to ensure that there is a flushing fluid supply at the head of the device and to clear the supply line of any sediment build-up that could prevent fluid from being delivered and to minimize microbial contamination due to sitting water. Routine flushing must be recorded on the Inspection Tag attached to the equipment.
