    #671607 - 06/10/02 12:17 PM (15 years, 5 months ago)

Ok.... so i found this stuff @ Westlakes called Oil-Dri. It says on the back that it is crystalline silica quartz... is this what I am looking for? Thx for the help.

yes, silica crystals will work. however, Calcium Sulfate (DrieRite - www.drierite.com) is superior - it works faster.

Well... as long as these will work, they are much better on my budget... Dri-Rite is fucking hella overpriced here where I live. They only sell the small sizes... with the little bag of Dri-Rite in the bucket. I'd have to buy like 6 of these @ 4.00 apeice to get a half-way decent amount of the stuff. So as long as these will work...

why ask a simple dessicant question in the adv cult?
-------
DrieRite is not very expensive. You can get it for ~1$/lb delivered...

Because nobody knows what dessicant is in the reg. Cultivation forum it appears. Maybe you could answer my question and let me know if the stuff I described will work...?

PEL - OSHA Permissable Exposure Limit. TLV - American Conference of
Governmental Industrial Hygienists (ACGIH) Threshold Limit Value. TWA - 8 hour
Weighted Average. STEL-Short Term Exposure Limit.




*** SECTION III, HAZARDS IDENTIFICATION ***


EMERGENCY OVERVIEW

This product is non-combustible, chemically inert mineral. This mineral sample
contains a small amount of naturally-occurring crystalline silica as quartz.
Prolonged overexposure to respirable crystalline silica may cause lung disease
(silicosis). IARC, in Monograph 68, has concluded that crystalline silica
inhaled in the form of quartz from occupational sources is carcinogenic to
humans (Group 1); however, carcinogenicity was not detected in all industrial
circumstances studied. Because applications and exposure data indicate that
exposure to respirable quartz in this product with normal use is well below the
OSHA Permissible Exposure Limit (PEL) and ACGIH Threshold Limit Value (TLV); and
because the company is not aware of any scientific or medical data available
indicating that exposure to dust from this product under conditions of normal
use will cause silicosis or cancer; adverse effects would not be expected from
normal use of this product.

HEALTH HAZARDS

INGESTION: No adverse effects expected with unused material.

INHALATION: Inhalation of excessive concentrations of dust may cause irritation
of mucous membranes and upper respiratory tract.

EYE: Contact may cause mechanical irritation and possible injury.

SKIN: No adverse effects expected.

SENSITIZATION: No adverse effects expected.

CHRONIC/CARCINOGENICITY: Inhalation of excessive concentration of any dust,
including this material, may lead to lung injury. This product contains
crystalline silica. Excessive inhalation of respirable crystalline silica may
cause silicosis, a progressive, disabling and fatal disease of the lung.
Symptoms may include cough, shortness of breath, wheezing and reduced pulmonary
function. The International Agency for Research on Cancer (IARC), in Monograph
68 has concluded that crystalline silica inhaled in the form of quartz or
cristobalite, from occupational sources is carcinogenic to humans (Group 1).
However, in making the overall evaluation, the Working Group noted that
carcinogenicity was not detected in all industrial circumstances studied.
Carcinogenicity may be dependent on inherent characteristics of the crystalline
silica or on external factors affecting its biological activity or distribution
of its polymorphs. The National Toxicology Program (NTP) classifies crystalline
silica as reasonably anticipated to be a carcinogen. Because applications and
exposure data indicate the exposure to respirable quartz in this product with
normal use is well below the OSHA Permissible Exposure Limit (PEL) and ACGIH
Threshold Limit Value (TLV); and because the company is not aware of any
scientific or medical data available indicating that exposure to dust from this
product under conditions of normal use will cause silicosis or cancer; adverse
effects would not be expected from normal use will cause silicosis or cancer;
adverse effects would not be expected from normal use of this product.

MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
None currently known.



*** SECTION IV, FIRST AID MEASURES ***


EYE: Immediately flush eyes with cool running water, lifting upper and lower
lids. If irritation persists or for foreign body in the eye, get immediate
medical attention.

SKIN: None needed for normal use.

INGESTION: If used material is ingested, get medical attention due to
possibility of chemical contamination. If large amount of unused material is
swallowed, get immediate medical attention.

INHALATION: Remove to fresh air.

It is an absorbant, not designed for dehumidification, as is damprid and drierite. It is not a good substitute, as was indicated by the first response to your post. It *can work, but not very well.
Drierite is not very expensive, and is fully reuseable. Same with DampRid.
