Perlite the MOST DANGEROUS humidity tek can cause/aggravate lung disease and cause silicosis

Check out the MSDS data sheets on perlite if you think I am wrong.
http://www.perlite.co.nz/safety-pumice.htm
Here is a perlite Toxicology: Inhaling crystalline silica-containing dust can aggravate upper respiratory conditions such as asthma or emphysema. Long term exposure to mineral dust which contains crystalline silica can cause the lung disease silicosis.
A recent review by the International Agency for Research into Cancer of public literature on the carcinogenic risk of silica and silicates has concluded that there is limited evidence for the carcinogenicity of crystalline silica to humans'.
http://www.pennperlite.com/msds.html
Caution and Warning: Keep Out of Reach of Children. Do Not Take Internally. Dust created while pouring into paint may cause eye, nose, throat or upper respiratory irritation. Long term breathing of large amounts of mica or talc may cause lung disease. This product contains small amounts of naturally occurring Crystalline Silica that has been identified by the International Agency for Research on Cancer as a Carcinogen. Emergency Product Safety Information: 800-821-7352
This product may contain crystalline silica (less than 0. 1% - see section II). OSHA considers Perlite a nuisance dust and recommends a PEL of 5 mg/m3 TWA respirable dust. Inhalation over long periods of high amounts of any nuisance dust may overload lung clearance mechanism and make the lungs more vulnerable to respiratory disease.
http://www.norcalperlite.com/MSDS.htm
Inhaling over long periods of high amounts of any nuisance dust may overload lung clearance mechanism and make lungs more vulnerable to respiratory disease.
Medical conditions which may be aggravated: Pre-existing upper respiratory and lung disease such as, but not limited to bronchitis emphysema and asthma. Target Organs): Lungs Acute Health Effects: None known Primary Entry Route: Inhalation

Yeah screw perlite. It's not worth working with to me. For anyone who may not know, MSDS is a chemical safety system used by the professionals who work in labs for companies & universities..it's not to be taken lightly!!

In most areas walking outside would do more damage to your lungs than perlite.

i would like to add that when dealing with dry perlite it is always recommended to wear a mask. perlite is bad to inhale.
when wet it's 100% ok to deal with as long as your not stuffing it into your mouth.

um... thats not news.
Thats why teks say to pour water in the bag before opening to minimize dust. In fact I think the bags themselves recommend that.

Ehm, I've used perlite in things other than mycology..my statement is based on experience of perlite (as its own hazardous entity) alone. I don't use it for soil; I don't use it for anything...
And since I know that there are ways to avoid perlite in mycology, easily, working perlite is just not worth it (to me).

My only point here is, surely there are teks that provide humidity, without introducing into your home, a caustic substance.
As perlite dries on the top, FAE stirs it up, onto your fruits, into the room air, into your lungs.
EVERY TIME you FAN.

i use lavarock instead of perlite personally just because its messy and you can't reuse it. think green!

so, silicosis eh?
taken from wikipedia, which isnt exactly a source of accurate information...but w/e, it'll suffice.
"Inhaling finely divided crystalline silica dust in significant quantities can lead to silicosis or (much more rarely) cancer, as the dust becomes lodged in the lungs and continuously irritates them (silica does not dissolve over time). This effect can be an occupational hazard for people working with sandblasting equipment, products that contain powdered silica, and so on."
...if you develop silicosis from opening one or two bags and breathing the dust, chances are the world didnt need your bad genes in the gene pool anyway.
ill contest that the particles of perlite arent small enough to truly cause a horrible problem, at least not at the levels mushroom cultivators are breathing in it. MAYBE, just MAYBE if we worked in perlite factories for days on end, we might develop some problems.
lets just tone it down a bit capt. theres bigger health crusades to get involved in with mushroom cultivation than perlite.

I think this is a good thread for some noobs to come across. Some people don't wanna add to their chances of getting cancer or destroy their lungs any more than the natural environment already does. Others don't care. Either way it's good to know that each time you deal with perlite it's inevitable that you'll breath in shards of silica(con?)

if its dry..and you are not wearing a mask.
im sure its no worse then sitting in traffic. the title should be "reasons to be cautious when dealing with any silica product"

Just so you know Private Cubensis I'm in the medical field and I know for a fact that when the perlite is moist and there is no room for aerosols even when fanning you can't inhale the perlite dust particles.
In saying that. Everyone here already knows to wet the perlite before messing around with it. And if they don't they will find out soon enough before any potential damage is done to the lungs.
When the perlite is moist the percentage of aerosols is drastically reduced meaning that it would take multiple lifetimes to inhale enough of it to do long term damage.
Unless your link to your study says they were putting they're heads in bags full of perlite and inhaling til no tomorrow.
So could you not fill these rooms with rhetoric's.

Hey Futurewolf...Have you read my post on Captain Cubes other long thread he started? If not, go read my reply and see what you think!
-------------------- "In Vino Veritas" Mycology (from the Greek μύκης, meaning "fungus") is the study of fungi, their genetic and biochemical properties, their taxonomy, and their use to humans as a source for tinder, medicinals (e.g., penicillin), food (e.g., beer, wine, cheese, edible mushrooms) and entheogens, as well as their dangers, such as poisoning or infection.

Seems like if you already have read the MSDS sheets then you would just ignore the thread, having nothing to add except what everybody already knows.
Did everybody know the term silicosis? Cause this is the only thread of consequence that comes up, search the posts man!
I don't think RogerRabbit has ever commented on silicosis in 12,500+ posts!
