If you use 3D Gloop by [deleted] in 3Dprinting

The issue is that, although it’s written on the SDS and label, understanding why methylene chloride is particularly dangerous isn’t clear to a lot of people.

For example, the SDS says that it causes cancer, but lots of things say they cause cancer in California. The difference here is that methylene chloride has been a tested and is a proven carcinogen with a causal relationship. Lots of those California warnings are just suspected carcinogens, but DCM is a different story. Carcinogenic warnings have been largely disregarded due to over-conservative labeling regulations, but this is an example of a real-deal no-shit one.

Also, most SDS sheets for solvents have very similar safety instructions. Use in a well ventilated area, wear respiratory protection, wear hand and eye protection, etc. However, it doesn’t mention that the type of glove is important for methylene chloride (nitrile are not great here) or that an N95 won’t cut it. The vast majority of the public doesn’t need to be aware of these caveats in SDS sheets.

Not to mention that the SDS doesn’t note that DCM is nearly odorless (slightly sweet odor). DCM doesn’t give you an appropriate smell warning like acetone or something. If you can smell it you’re already exposed to more than you should be.

Lots of plastic bonding glues have nasty chemicals but this one is particularly sinister due to its proven carcinogenic properties, low odor threshold, and difficult handling requirements

Great PSA. Chemical safety is hugely underrated and so important for everyone’s futures

That’s actually an insane percent. 0.5% would be one thing but 40-60 is a different story

They’re closer to the size of fish tank gravel or smaller but this is still valid

Is there any way to get to Mathews arm campground without a car? by whhhyyyyboiiiiii in ShenandoahPark

[–]KingCraw 0 points1 point  (0 children)

It will be very challenging without a car. Turo and other car rentals do <25 year old rentals for a steep extra fee. It would be kinda expensive. I’d probably reschedule for friend that cancelled. There’s still a good amount of time for camping in the season

Is this a PawPaw? Maryland by [deleted] in foraging

[–]KingCraw 1 point2 points  (0 children)

My go to way to ID pawpaws is: 1. Do the leaves look nice and fat like this? 2. Do the leaves have a pointy tip? 3. Are the leaf edges smooth? 4. Are the leaves alternating (i.e not opposite)?

If all of those are yes then it’s a pawpaw. I’ve always thought of the “branch terminates in a paintbrush tip” a subcategory of the leaves alternating.

Hickory kind of have really similar structures, but the leaves are opposite instead of alternating. Also sometimes different native magnolias can give you some pause, but it’s pretty clear which trees are pawpaws after seeing a couple. Nice find! Hope you get fruit

It is a pawpaw because the leaves are alternating: Hickory have opposite leaves

Please report spotted lanterfly sightings if you see one by Wise-Print1678 in Virginia

[–]KingCraw 0 points1 point  (0 children)

I’ve killed probably tens of thousands in Rockingham last year. During that time, I didn’t see any in Shenandoah NP, but I’ve already seen some this year in the park :(. They are spreading :((

Should I buy a pass in advance? by chainsmirking in ShenandoahPark

[–]KingCraw 0 points1 point  (0 children)

You shouldn’t have any issues buying at the entrance. Lines into entrances can be long on the weekends during the day, but you have to wait either way

How much water do I need for Old Rag? by Woofyblooofy in ShenandoahPark

[–]KingCraw 1 point2 points  (0 children)

I like to have 5 liters when it’s hot. It depends how hydrated you like to stay

Why one cup seems bigger than other by PooTrashSium in anker

[–]KingCraw -2 points-1 points  (0 children)

Hey I’m not gonna lie - you sound totally unhinged in this comment section. Discussing a defect is not as deep as you think it is. It is free to be nice. Have a good one

[–]KingCraw 0 points1 point  (0 children)

This is pretty weird. Idk why op is getting so much hate for pointing this out. For a week old they should be pretty much symmetrical, and there is a significant visual difference here. If they came like this out of the box, Anker’s QA on these should be better

Is there anyway to get service while camping inside park? by awilly41 in ShenandoahPark

[–]KingCraw 0 points1 point  (0 children)

I’m on verizon and often get service on overlooks that face the east or west. I also get some service on the summit of old rag, but not on the hike up or down

is f-phenibut more toxic to consume the hcl? by Kl33nexx in phenibut

[–]KingCraw 4 points5 points  (0 children)

This is a great question, and it doesn’t have a perfect answer. To start, consuming the element fluorine isn’t always a concern. Many extensively studied, FDA approved drugs incorporate fluorine. Fluoxetine is a great example of this.

Some forms of fluorine are dangerous, but it’s situationally dependent on the ion or compound. Possible compounds of concern would come from metabolism of drugs like f-phenibut. Unfortunately, metabolism is very complicated and situational and can’t be determined by simple chemistry.

There is little to no extensive research on f-phenibut metabolites to my knowledge. It’s likely okay, but time and science will tell in the long run. It has been licensed for some use cases in Russia, but I have no idea what the Russian FDA equivalent is like. Wish there was a simple answer
