"Steel structures may moan and creak, but they should never pop or bang. If you hear steel making sounds like someone is hitting it with a hammer, you should probably get out from underneath it."

"We used to go into the swamp, roll down the car windows, and play the baby gator sound from the stereo to get them all to come out of the water and towards the car. We were dumbasses, but it gets boring out in the swamps."

"Also, any rotating equipment, like motors or engines, should never change speed unexpectedly. It may change load, sounding like it's working harder, but change in speed without a change in load means something is going wrong, like the motor is seizing. That's a 'take 10 steps back' moment. The real scary moments happen when you hear a motor experience an unexpected increase in load, accompanied by a decrease in speed, indicating it is significantly overloaded. That's a 'run away' moment because something in the system is about to let go, and will take you with it."

"I was on Mt. Rainier and witnessed an avalanche. That wumps sound right at the start was something I had never heard before and couldn't understand, like the mountain had become a drum, so I froze. Then I watched far more snow than I ever realized could slide at once just drift away like it was nothing, and that was the loudest sound I've ever heard. It's hard to put into words, I think. It's like the sound of concrete falling into more concrete, but louder than a jet. It was unreal.

I only had to hear that once to learn what it meant and remember it forever. If I had just been on a slightly different hike that day, there would have been nothing I could do to save myself. I don't know if anyone was hurt. This was the summer of 2008."

"As a new paramedic, infants/babies always scared me, especially if they're crying. Then I had a couple kids of my own and hooooooly shit, a quiet, sick kid is way more worrisome."

"It means they all became acutely aware of your presence and intention. All 60,000 of them."

"The point is to keep blood going to the brain just long enough to get your loved one to a medical professional.ย  And if you don't care about your door being smashed in or whatever it takes to get to you, remove that step from the above text."
