Best Management Practices?



Hello. 
 
Can anyone recommend BMPs for minimizing potential mercury releases from the following components within potable water treatment systems?  (I have information on non-Hg alternatives, just looking for BMPs in cases where replacements are not able to be done right away.)
 
- float switches (in tanks, pumps, wells, etc.)
- tilt switches (not sure where)
- UV lamps (germicidal treatment)
 
Many thanks.
