DCHAS members,

From what I could decipher, it seems like a possible delayed exotherm from a storage container (flask, bottle). What was the material, etc.? Cannot say at this point, and speculation would be moot.

It does seem that the cabinetry did perform effectively, which is always a good thing.

The vapors identified may not have been emulating from the point-of-incidence; hopefully a follow up will be forthcoming that we can all read and discuss.

Thanks for posting this, Dean.

The take-home message from them:


Overall, he said, the safety measures that were in place did what they were designed to do.

"The cabinet did its job," he said. "It's proof that those safety measures work."


I would like to seen their  after action investigation report.

Their engineering controls did appear to work.  But-

"An ounce of prevention is worth a pound of cure."

I wonder about their administrative controls in place =E2=80" especially their chemical storage and inventory program. 

I might speculate a chemical storage issue: incompatibility and/or chemical expiration issue. 

If this was the root cause, it would have been preventable.
