Please note that your check valves and other back-up stops need to be
checked regularly for functionality as even a little water in chlorine makes
it eat valves and metal quickly.  I oversaw a large loss in Nevada years ago
where the check valves had flat spots from erosion/corrosion/wear that made
them non-functional so that there was no way to stop the flow of chlorine
from the tanks and out through a pipe elbow that failed.  The leak was
eventually stopped by dismantling pipes and inserting a blind flange in
place of a gasket.  Messy, expensive and should have been unnecessary.  The
resulting evacuation of a town and hospital and loss of many pets and
gardens was not popular.  Typically the piping is more at risk than is the
tank itself.

Subject: [DCHAS-L] Chlorine Cylinder SOPs or Contingency Plan

Does anyone out there have a SOP or a Contingency Plan for responding to a
chlorine cylinder leak or rupture?  We have 1 ton cylinders that are used
for our water treatment systems.  

Thank you,
