Harbor Freight Tools that don't suck

I just presumed people spraying paint would wear a respirator and goggles. That's common sense.
I can't imagine painting without both, for anything longer than a few moments spraying downwind with a spraycan.

Question - since this is the HF thread: Is HF's respirator up to pro specs?

PhysAssist..Anything I ever post you are more than welcome to off-tangent and let me encourage it. That's where we learn stuff and things you say are worth hearing. Count us on the exact same wavelength. I wear a half face filter with pre-filters and chemical filters by 3M. No HF there. my goggles are again 3M and are also shatter proof because I'm a guy. I only paint outside and only HVLP. There isn't enough overspray to hit the paper.

There is new data from --I think 3M--that allows limited spraying of isocyanates outside on a calm day while using their dedicated filters. You can re-use those filters for maybe a week or two and then they have to be replaced. Maybe I'll try it--maybe. I posted the info and filter numbers somewhere else here but if need be I can find it.

Thanks for all of the above.

FWIW...for 45 + years I've had a fiberglass/polyester fabrication side business...can't count how many 55 gal. drums of acetone I've been through...Always tried to work with good ventilation...there are much worse (harmful) solvents out there than acetone...

Acetone is not considered either a VOC (volatile organic compound) or a HAP (hazardous air pollutant) like almost every other chemical solvent...

It it is great for removing grease or oil before applying a finish or welding etc...

While the EPA may have reclassified Acetone, it still fits the definition of VOC, even if it is no longer in the HAP one:

"Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air, a trait known as volatility. For example, formaldehyde, which evaporates from paint and releases from materials like quartz, has a boiling point of only ?9 ーC (? ーF).

VOCs are numerous, varied, and ubiquitous. They include both human-made and naturally occurring chemical compounds. Most scents or odors are of VOCs. VOCs play an important role in communication between plants,[1] and messages from plants to animals. Some VOCs are dangerous to human health or cause harm to the environment. Anthropogenic VOCs are regulated by law, especially indoors, where concentrations are the highest. Harmful VOCs typically are not acutely toxic, but have compounding long-term health effects. Because the concentrations are usually low and the symptoms slow to develop, research into VOCs and their effects is difficult."


...Anthropogenic sources
Anthropogenic sources emit about 142 teragrams of carbon per year in the form of VOCs.[15]

Specific components
Paints and coatings
A major source of man-made VOCs are coatings, especially paints and protective coatings. Solvents are required to spread a protective or decorative film. Approximately 12 billion litres of paints are produced annually. Typical solvents are aliphatic hydrocarbons, ethyl acetate, glycol ethers, and acetone.

I was not aware of any reclassification...but compared to most other chemical solvents acetone is rather benign...

So is pure ethyl alcohol -- and with NO toxic effect. Just a benign contact high. :drink:

And then there is MEK, great for de greasing but side effects!
I've always had acetone on hand so I rarely had a call for other solvents...I did/do use MEK 90 as a catylist

It's likely not recommended for first aid...but acetone is great for cauterizing minor wounds...

that's a local product in these parts...:D

A friend of my wife told us her husband was just diagnosed with a brain tumor and inoperable cancer, has 6 months to live.

His career was stripping military aircraft for repainting, mostly using MEK.
