Thank you for sharing this. I agree that luck should not be part of a
safety program, but I am glad that it was this time.
This reminded me of a former graduate student ( about 20 years ago) who
went to work for a company that manufactured silane products. A few years
into his job, he unintentionally blew up half of the plant in which he was
working. He later committed suicide; I1ve always wondered if the accident
played a psychological role. There are secondary effects from chemical
accidents that are often never mentioned.
I am glad that you are OK. Things could have been much worse.
Thank you for sharing this. Sometimes when things go wrong with people who
are committed to safety, it reminds us that accidents can happen even
under the most careful of circumstances.
Be well.
