Re: Things you only do ONCE!
 

Quoted for truth. I had to go to the ER last season when the piece I was drilling got caught in the bit.

I did this one and now whenever I use a chop saw I check, we were dumb and didn't place the saw in a good place so when I went to cut a metal tube the power cord fell and went into the saw causing quite the fireworks and scare.::ouch::

233. Get into the top 8 at an event without a scouting list.

234. Test angle-correction gyro code for the first time while tethered.

235. Not make a pre-match checklist.

I understand completely.

Put any kind of butt on the PD Board!

I think he meant NUT.

Re: Things you only do ONCE!
 

That is true. BTW, let me say, that was before my first safety lesson. Thankfully I didn't hurt myself, but now I drill with a vise or a clamp. Also, I typically use a drill press because even though it has a stronger motor, it seems safer because the bit is less likely to move and cut a finger off.

So back onto the topic:
don't touch both terminals of the battery, especially if it is raining and you just came in, wet!
Don't touch spinning motors. Those BAGs may seem tiny but they pack some force and some speed for their size. Even worse, don't touch those old-and-trusty CIMs!
Don't touch a robot if it is on and enabled. You don't know when something can go awry and the next thing you know is the robot is pushing full-force towards you, likely to hurt you! Always disable and/or shut down the bot before doing things.

224. Make a thread about Things you only do once! ;)

I meant nut. The phone screen is little and my fingertips are not.

So here's another one: Let anyone (student or mentor) use a tool or machine for which they have not received training and signed-off safety certification.

Re: Things you only do ONCE!
 

There's safety certifications for screw drivers? :P

And not checking an output voltage with a multimeter before connecting the expressive radio.

227.
Run an electronics board assuming everything is okay even though it has sat for 9-10 months.

228.Not knowing to check that the regulator was not properly adjusted. And learning from a loud high pitched noise that something was wrong.
Luckily there is no noticeable damage.

Re: Things you only do ONCE!
 

Yes. On our team it's called General Shop Safety.

Re: Things you only do ONCE!
 

Exactly. Even a screwdriver needs a "not a prybar" primer. General shop safety certification comprises hand tools.

Team alumni from CSU were helping us find a leak in the ball. Instructions were to:
1. Fill ball partially with air
2. Put in sink full of water
3. Use bubbles to isolate leak

What they did:
1. Fill ball fully with water
2. Put in empty sink
3. Laugh
4. Not find leak
