Dunny chemicals

As I said i'll let you know how i get on.

I was thinking of vacuum packing in .5kg lots and hope that will help it last.

Having been involved with the handling of this and other similar chemicals, I take safety seriously. I urge you to read the MSDS on any chemical you may use.

Here is one copy http://rrworthogs.tripod.com/archives/percarbonate.pdf

In partcuar note....
Storage and Handling
• Store in a dry location away from heat and out of direct sunlight in containers fitted with a
safety valve or vent. Storage temperature: <104°F (40°C).
• Store in an area away from acids, bases, metals, metal salts, reducing agents, organic
materials or flammable substances.
• Never return unused product to the storage container.
• Rotate inventories - first in, first out.

I would urge you to store only a small quantity in a suitable container within the RV.

Good advice

Sounds like it's going to do a pretty good job on the pot!

Once the Sodium Percarbonate hits the water it starts to dissolve and produces hydrogen peroxide, which is a very strong oxidant. It then converts to oxygen and water. The oxygen is used to decompose waste matter, and helps remove the smells up into the stink pipe. The residual component is ONLY water. Using too much will create too much oxygen, and the reaction will mostly cause the smell to become too prominent. Oxygen only reacts to waste, not urine which is sterile to start with.
This is a great product for the Black water tank provided you use it in suitable measure, i.e. approx one teaspoon per person per day of 30% (300g/litre) active ingredient.

Thankyou for the chemistry lesson Jon!
Now maybe you can help me with another tricky one?
Going through my goodies I've had hoarded away for many years as I move abode I came across an old fashioned light that many years ago was used on pushbikes among other uses. (mines etc)
From memory it had a powder in the base & an acid dripped into it to create a reaction that produced light.
Can you enlighten me/us re the chemicals used?

[Jon and Kay]

Sorry Bruce, I only look that old. Can you let Centrelink know...I'd appreciate a pension
I would have thought that acid onto a fuel source would have been too difficult to dispense without blowing your head off.
There were Mercury Lamps...but...

I was once employed to find out why the neighbour of a swimming pool owner had his neighbour's 500kg sand filter on his lawn. Taught me that the unexpected can happen if you ignore the power of a chemical improperly dispensed.

Carbide (spelling)

[Jon and Kay]

Yes, Bernie you're probably right, still used Today. But no acid, just water.
