Hazmat could be there simply because someone accidentally mixed bleach with ammonia (like what happened at Union Market last year) or something else. They're just the crew that has the appropriate protective gear and experience to go in and deal with it and make sure the building is safe for people to go back into.

If it wasn't on the news and didn't break out into social media, chances are it wasn't anything significant.

Nope. Chemistry is too woke or something. /s

Not knowing what's in what makes it hard to avoid accidents unless you take time to read the MSDS, which I wager most people won't do.

Most people don’t even know what an MSDS is

Technically it’s just “SDS” now since the Globally Harmonized System of hazcom (GHS) went into effect in 2016.

Funny, I started in my field in 2016 and I’ve rarely heard it called SDS

Imagine you pay an education development contractor a gazillion dollars in 2014 to put together your new employee safety training videos. Budget doesn't allow the next update until 2024. MSDS it is.

IIRC, it standardized the format of MSDS/SDSs, placarding, all that stuff. A lot of folks in my industry still refer to it as MSDS too. Semantics really.

I think they just call it sds these days. Not sure why.

United States: GHS compliant labels and SDSs are required for many applications including laboratory chemicals, commercial cleaning agents, and other workplace cases regulated by previous US Occupational Health and Safety Administration (OSHA) standards. First widespread implementation set by OSHA was on March 26, 2012, requiring manufacturers to adopt the standard by June 1, 2015 and product distributors to adopt the standard by December 1, 2015. Workers had to be trained by December 1, 2013. In the US, GHS labels are not required on most hazardous consumer grade products (ex. laundry detergent) however some manufacturers which also sell the same product in Canada or Europe include GHS compliant warnings on these products too.

It's MicroSoft Disk System! Duh! I used it all the time back in the day to play Doom and Commander Keen.

I mean if I run a restaurant I'm either only allowing products with bleach or only products with ammonia, but never both! It's just too risky.

I learned a lot in high school chemistry, but the ammonia+bleach thing was covered exactly 0 times.

I remember learning about it in 7th grade. It wasn't in chemistry class, it was because we all read A Child Called It. It was a memoir from someone who experienced horrific child abuse. One of the things his mom did was mix ammonia and bleach and make him clean the bathroom, breathing in the toxic fumes.

Your 7th grade class was reading A Child Called It?

Wow

(When I was in 7th it was either Johnny Tremain or A Separate Peace)

Trying to make kids appreciate their lives more? Learning empathy? I do remember that 9/11 happened at the beginning of my 7th grade year. I don't know if that affected the curriculum at all. Take it up with my English teacher I suppose.

Same here! Also… my chemistry course was 100% text book based and we never once touched any lab equipment. (Varina High 2006ish)

I was lucky. My teacher loved using fire in class and was well known in my tiny rural school for having the coolest demonstrations.

That’s awesome!!! I had looked forward to chemistry (and biology, etc) since elementary school and boy was I severely disappointed for all four years 🤣

At John Rolfe Middle school in the 80’s, we had a cool science teacher that did a lot of science experiments. She explained the proper way to mix alkaline and acid. We also got to break fruit that had been frozen in liquid nitrogen.

That’s awesome! My freshman year I had Ms. Shirey for Biology and that was the best class I’ve ever had.

She was interested, knowledgeable, engaging, and reasonable; something I craved as a kid and still look for today in mentors.

You think these kids are cleaning? /s

Edit: I assume the reason they don't tell children how to make deadly gasses is so that they don't make those deadly gasses in school.

Nope, Chemistry teachers are too busy re-teaching kids basic math, literacy, and human decency.

We mix soap with our bleach at work. Not much though.

I mean, making mustard gas in the shop is a bit of a big deal.

Edit: ok fine, not mustard gas. Whatevs

fusion260 t1_je9yij7 wrote

It is, if that's what it was, but it wasn't. Bleach and ammonia make chloramine gas, not mustard gas; the latter requires additional components that I won't list here.

Chloramine gas is still dangerous until it's dealt with and the space is fully ventilated, but not to the power and severity and immediate danger that mustard gas has.

That said, again, as a PSA to everyone: do not mix bleach with anything else other than water.
