Stump Grinder

The pink grinding wheels are Aluminum Oxide. Probably the same hazard.

The green wheels are silicon carbide.

Is that the same for the Pink wheels you use on chainsaws? Man, I am a dead man given how much bad stuff I have inhaled.

Yeah. Think back in your life and all the stuff you have been exposed to that is now deemed deadly.

Asbestos fibers, lead paint, MEK, DDT, you name it. We'll either die young or live really long, depending on if it eats us or preserves us. :confused3:

Aluminum is supposed to give you alzhiemers... What was my question?

I don't think that pink aluminum oxide is exactly good for you, but it's not in the same league with grinding tungsten carbide+exotic alloys on a silicon carbide wheel. I wouldn't worry too much about it - after all, you probably drive on the freeways in Southern California. The exhaust fumes alone...

Silicon carbide is pretty inert, but still toxic; aluminium oxide is pretty non-reactive, but I don't recommend inhaling anything besides pure air...

15/53 silicon carbide crushers had lung disease in one study. The federally mandated maximum exposure levels are 5miligrams/cubic meter of air (NIOSH/OSHA) for both of them, i.e. wear the facemask.

All the best,

I'm pretty sure lungs work best breathing air. Dust of any sort clogs things up. We would probably all do well to wear a respirator, dust mask, or at least a bandanna when we're grinding or even just mowing in dusty conditions. It's like the asthma PSA says: when you can't breathe, nothing else matters.

I remember my dad telling my how when my grandpa owned a construction company in the 60s he used to cut asbestos sheet with a skil saw.:laughing: (now you need a big team of guys in hazmat suits with HEPA filters cleaning the air to remove a little piece of that asbestos sheet)

Don't laugh. My father built our house out of cemesto panels. He used a circular saw to cut them all. There were lots of pieces left over and we made forts out of them when we were kids. Used to cut them all the time. God only knows what else we got into.

I was not laughing at the way we used to handle asbestos and other things we now know are very hazardous to our health. What I was laughing about was how things that used to be handled in a way we would never handle them now. For example when my father was in high school, the science teacher passed around a blob of mercury so people could see what a metal that was liquid at room temperature is like. They just were rolling around mercury on the bare skin of their hand, now to handle mercury people would be wearing gloves and respirators and not letting it touch their skin. People handled things like mercury and asbestos that way because they didnt know that they were dangerous, that is nothing to laugh at. All I was laughing about was how people react to things now compared to say 40 years ago. Another example is how kids used to sit on the floor in the back of a station wagon, when now people can get quite a large ticket just for not wearing a seat belt. People handling things in a dangerous way because they didnt know it was dangerous is something I would not laugh about. I am sorry you took my remark that way, I did not mean to offend anyone, but I can see how you took it that way and I understand exactly how you feel.

I'm sure MR didn't think you were laughing, but just using an expression.

When I was a kid, we panned for gold. Dad would take mercury and put it into the container with all the black sand and gold. The mercury would attach to the gold, and he then put it into a cast iron frying pan. Under heat, the mercury would evaporate, leaving the gold. He'd hold bread heels over the evaporating mercury to recapture it.

That would've been the early fifties. Factor in NO seatbelts, metal dashboards and non-collapsing steering columns, and it's a wonder any of us are alive today.

None of it is "funny ha-ha" now. "Funny strange" would apply to our collective ignorance.
