Heard a stat about boiler pressure vessel failures that stopped me cold

I was reading the latest National Board report for last year, and one number really got me. It said over 60% of boiler incidents they looked into were linked to low water conditions. I always knew it was bad, but seeing it put that high was a shock. We had a scare on a job in Toledo about six months back where a low water cutoff was acting up, and this just drove it home. It made me go over all our checklists again, especially for startups after a weekend shutdown. I'm telling my crew now to treat the low water alarm like a fire alarm, no questions asked. Has anyone else had a close call that made them change how they run their water level checks?

Our shop foreman always says a boiler without water is just a bomb waiting to go off. That stat is terrifying but makes total sense.

Okay but like, isn't that a bit over the top? Modern boilers have so many safety cut-offs and low water trips. It's not like the old days. That stat probably counts ancient equipment that nobody maintains. If you follow the manual and do basic checks, the risk is super low.

Oh man, that reminds me of a story my uncle told me. He worked at this old paper mill back in the 80s and they had a boiler that would just randomly start screaming like it was dying. Turns out the low water cutoff was clogged with mineral deposits. They'd been ignoring the maintenance schedule for like a year because the manual said to check it every month. No one died but the whole plant had to shut down for three days while they flushed the system. So yeah, modern safety stuff is great but only if you actually maintain it.
