ANSI regulations state that:
Drench hoses with single heads do NOT meet all the criteria of an eyewash station. Dual head drench hoses DO meet all the criteria of an eyewash station because they feature a stay-open ball valve that allows for hands free operation.
A drench hose, single or dual head, can NOT be substituted for a drench shower. It is considered a supplemental device only because it cannot supply the 15 minute full body drench required.
