Doing anything interesting at work today?

I would like to see how you test a fireproof, waterproof door. It sounds fun.

Allow me to illustrate:

I started a new job on 12/20. I worked (and I use that term loosely) for ~3.5 days, then everyone in my group took the week of the 27th off, then the company was closed until 1/10. So I actually start next week.

Installing emergency lighting equipment and a siren on a Chevy Tahoe.  Another county EMS whackadoodle idea.  We'll see how it works.

Cutting carpet insulation for a 1952 MGTD.

Ordered tires for a customer's Honda CM90

Booked the Pinto swapped Cortina into the exhaust shop next week.

I've posted the quarter-sized test rig we designed before.  When I get home I'll write something up.

It is two different tests though. 

I bet I can make it into one test. At least once.

Like I said, these are two different tests.  The fire tests have different temps for different time ranges (which makes sense, the longer a fire burns the hotter it gets.)  If I remember correctly, for the 90 minute test they crank the oven to 1800F and then run it for 90 minutes.  There's some fine print, but basically you can't have any live flame visible from the non-fire side.  You test for the most extreme case and you are awarded a certificate for all the lower ones as well.  After the 90 minutes they get blasted with a fire hose to see if the door remains in its frame.
Flood proofing is a similar thing, different ratings have different head pressures, doors get rated at the amount of leak per unit of time (hour, I think.)  Despite being small we are one of the better flood companies out there, some of our systems are rated at 100% flood proof which I think is an industry first.

The metal doors get enough heat transfer that they glow a dull red on the "cold" side.  This is why we failed, the door got hot enough that it ignited a seal.  We are semi confused about this as we haven't had that happen previously.

Generally I love testing, its one of my favorite things to be involved with.  Not that fun when it doesn't go right though.

My little test fixture:

Oh, cool.

I think we need another picture of what's drawn on that door :)

I'll see if I can dig one up

Fun fact, permanent marker doesn't burn off.  The Bee's Knees was still on the inside after a couple of burns.

Here's the hinge shown above after the first test.

I also started one on the 20th. But, since the company was able to be down for the holidays, us maint. folks got to work.

I envy people that actually do things for a living.  That's pretty cool!

Today was my turn for surgery. Spayed a 55 lb Labrador, 27 minutes "skin to skin" (incision to closed). I've done a big dog spay in less than 20 minutes, but it's actually quite a challenging procedure and an hour isn't unusual. 

That's quick, although nowhere close to the speed of a shelter vet, but I double ligate everything and do an extra layer when closing. My complication rate is nearly zero. 

That's pretty badass.

I've worked on similarly water-tight, fire proof (resistant) doors as well.

I do not always work on those but I have a berkeleying cool job.

I got to learn more about product led sales and hypergrowth today- and I've just stepped into the director of sales role for our company after being a BDM. 
exciting stuff, and I don't mind change- but man, if we really grow as projected it's going to be quite a ride the next few years.

That's where my mind went when he said worlds first! 
Was gonna make a joke about it, but wasn't sure it was going to come across as funny, so I erred on the side of caution!
