Monthly activation/flushing ensures the following:
- Eyewash and shower are functioning correctly,
- Contaminants and stagnant water are removed from the plumbing, and
- Units are accessible.
Laboratory personnel are required to flush eyewashes and safety showers in all active research spaces.
Flushing is not required while a laboratory space is inactive so long as the equipment is flushed prior to resuming active lab operations and then at least monthly while active. Please post a notice on the eyewash and safety shower if they are not being maintained due to lab inactivity.
Safety supply companies sell the 5-gallon bucket, curtain, and rod to make this task easier. Some labs just use a small tub to collect and dispose of flushed water. Since emergency equipment is often different in each lab building, the lab must use flushing apparatus that works for their particular system.
