I use this wheel to remove paint, rust and mill scale. It works great but wears out quickly and is a little expensive at $5 ea.

The results. It could have been much worse.

I did cosmetic surgery on two of my fingers with a flap wheel in a 4.5 in grinder like that

I had to remove the guard because the wheel wouldn't fit with it on. It's a 4 1/2" grinder and the package said it was a 4 1/2" disc but it rubbed the guard.

I guess I'm just nuts, but the first thing I did was remove the safety guard. I'm not braggin', just saying that safety guards do tend to get in the way. And, as LD said, "Spinny things can be dangerous".
I've also said that my former union reps would be proud of me, because in working with metal, I've started using safety glasses, as well as hearing protection, and a mask. Oh, and I also use gloves. And while I'm working, I'm as nervous as a "long-tailed cat in a room full of rocking chairs".

I always leave the guard ON my grinder, and not just for safety reasons.

Whenever I'm grinding, the sparks fly everywhere and I need to constantly adjust the guard placement to prevent the sparks from flying directly at me and messing up my clothes or schmutzing up my welding mask.

I always wear a welding mask with clear glass when I'm grinding, but the glass gets wrecked pretty fast if the sparks come directly at me.

A few rules will make grinding or welding a bit safer.

* No SYNTHETIC clothes (they melt - cotton is a much safer bet)
* No LOOSE clothes (they can get caught in the wheel)
* Clean up the balled up newspaper and greasy paper towels from under your workstation (I've set this stuff on fire on more than one occasion...)
* No loose jewelry or stuff hanging off - lanyards, drawstrings, etc.
* Wear heavy gloves, even if you just need the grinder for a second
* Don't grind things that can become dislodged and flung off (BRAKE/SHIFTER CABLES) (find that wire cutter instead!) Grinder+brake cable=horror movie weed whacker

I've broken every one of these rules, but I'm getting better. ;) No serious accidents yet.

hearing protection

Almost forgot about this one! I have so many earplugs in the garage with grinding detritus embedded in them, I could fill a coke can. Might need to invest in some proper ear defenders instead of contaminating my work area with used earplugs.

I can't underscore the need for eye protection at all times for all things spinny enuf.
Two trips to the emergency room to get small pieces of metal removed from the eyes would tend to make a person learn this...
Not I, make it 3 trips
Now my eyes are always protected -- and I still have 15/20 vision.
Who says *** doesn't look out for ya?

I guess I forgot to add the safety message, which was not to wear loose clothing while working with the grinder. I've been having some problems with this forum when I access it with Google Chrome.

I used to use earplugs, but then I came across some earmuffs for $3 and I absolutely love them. I can quickly pop them on and off again as often as I need. That doesn't work so well with earplugs, which get dirty very quickly, especially when you're handling them with dirty hands. Earplugs also take longer because you have to roll them, get them in straight, and wait a moment for them to expand.

The only thing they don't do is keep sparks out of my ears when I'm welding, because I can't wear them under my hood. That's when I wish my welders cap covered my ears!

To this day I dont know how I survived my grinder prang.
8" biggie, grinding out aluminium welds on a truck body.
Clothing - T shirt, lumberjack flannal shirt, sweat shirt, thick woolen jumper, boiler suit, leather biking jacket, leather apron.
Yes, it does get cold in winter in the UK.
The angle grinder had no guard, it caught and threw back at me hitting me in the chest.
It drew a thin red line from mid chest over the stomach (flatter in those days) and cut through every item of clothing.
I looked down in horror expecting to see my guts spewing out on the floor but they weren't.
I believe my heart beat exceeded 2000bpm that day.
I would like to believe I've learnt my lesson with power equipment but probably havn't.

Ouch.
In my volunteer ambulance days we had a callout to something similar. In his case the grinder had split his breastbone.
Could have got the heart etc. He was lucky. A quick trip to local hospital then air ambulance and he survived.

You just can't be too careful.
