Default use bulk formaldehyde as porta-potty chemical



the portable-chemical-toilet thing seems to have been originally based
on marked-up formaldehyde solutions as the deodorant.

I want to buy bulk formaldehyde and use that. How much is needed?

Bad idea!! Many campgrounds specifically ban the use of formaldehyde toilet
chemicals. Straight formaldehyde is dangerous to you as well. It used to
be used to "pickle" biology specimens. Problem is, the vapors can "pickle"
some of your sensitive parts too (like the lining of your nasal passages).

Don't use it. There's no reason to embalm your effluvia for future
generations. Formaldehyde stops aerobic and anaerobic decomposition in
septic disposal systems and bodies of water and is a health hazard.

True, but they do grow back, eventually*.

dissecting fixed specimens (without ventilation). Took him about 4
months to get his sense of smell back.

Read this article [Only registered users see links. ]
on the CARCINOGENICITY of formaldehyde.
"Formaldehyde (gas) is reasonably anticipated to be a human carcinogen
based on limited evidence of carcinogenicity in humans and sufficient
evidence of carcinogenicity in experimental animals (IARC 1982, 1987,
1995). Excess incidences of nasopharyngeal cancers were observed in
two of six cohort studies, three of four case-control studies, and in
meta-analyses. In addition, two of three case-control studies showed a
positive association between occupational exposure to formaldehyde and
squamous-cell carcinomas of the nasal cavities and paranasal sinuses."

Still it is used in medical schools and biological laboratories,
perhaps there is no better substitute of formalin for preserving
specimens,and in my country it is used as to fumigate poultry farms.
Do developed countries still use formaldehyde as fumigant?

Formaldehyde based toilet fluids are still available. They are often
coloured blue, which in the UK indicates poison and *danger*. The
manufacturers will have got the concentrations right. I *used to* use
them and treated the stuff with extreme care, and have now changed to Aqua
Kem Green because of the danger

DIY use of *dangerous* *poisons* is, as others have said, a *bad* idea.

OSHA TLV is only 0.75 ppm. It is a much maligned chemical ;(

Though I can't excuse Neons way of addressing Janet. Considering the source
I find Wills rebuke outrageously funny.

It may be overly maligned in some cases, but there is no doubt the hazards
are there.

Almost any MSD you pick up these days warns, in a CYA sort of way, of the
severe
consequence of being in the same world with all these horrible 'chemicals'.

I can't think of any modern microbicide which does not carry some of these
warnings.

In the old castles, they covered the poop with quicklime to keep the odor
(and possible
source of disease) down. Maybe the old technology is the safest.

I am reading this on uk.rec.caravanning.
Run my Thetford cassette loo on quicklime!
Fabulous thought!
What would you put in the flushing tank? ;-)
