I wasn't sure where to put this but am sure whaterver comes up in this thread will be good.

Last night I was writing down all the MSDS info for the chemicals I had and almost got scared, but was a good reminder.
I was actualy suprised that there wasn't much on the topic in this forum so this is why I am posting.

Safty is the number one priority when working with pyrotechnics. When dealing with any amount of any type of chemical a dust mask realy should be worn. If you dont wear one currently give a look through the Material Safty Data Sheets for the chemicals you come in contact with. If you value quality of life, I think your mind will be changing quickly.
this is the main ingrediant in the comp we all deal with the most,
of curse its only black powder,, but all those encounters will can add up.

Potassium Nitrate 7757-79-1 99 - 100% Yes

Chronic exposure to nitrites may cause anemia and adverse effects to kidney.
Aggravation of Pre-existing Conditions:
No information found.
try looking at something like barrium nitrate!

CHEMICALS: MSDS

This Isn't meant to scare people off but one can't deny the safty neccesary in every aspect of the hobby.
Where I am going with this is to discuss what kind of masks we should all be wearing where to get them how to use etc... as well as safty in general.

I got mine from a paint supplier. Its NIOSH aproved and has two filters.
It is made for paint so I figured it would be alright for what I am doing. Is this right is my question? I don't want no chemicals were they dont belong, like in my body. Some of my metal powders are as small as 2 micron, will these be filtered?

Everyone please stay green and I wish safe expirimentation to all.

I've been thinking about getting a new one as my current one is just a hight quality decorating mask. I really a proper (gas mask style) one with filters I can unscrew and replace. Does anyone know a good supplier for them? None of the DIY shops seem to stock them. I don't really want to get them off an expensive safety kit website.

Tris,

Try ScrewFix Direct or Machine Mart they have the type you are looking for and are reasonably priced. Good variety and some include full face shields and they stock the replacement canisters.

Try ebay. I just won a very good set with an extra 100 replaceable filters for a tad over $40. I believe the seller still has some more sets of the same mask and 100 filters for sale. respirator Hope that helps B)

pulled from a different thread,

a chemical rated/1 micron filtering respirator,

thanks burlhorse,
this is what I was trying to find out.

The paint supplier that I got my resprator from carried these so I went and picked some up, they were 5 dollers each!
This is a lot but is worth the price. Im glad I found this out before I got into some of the more toxic chemicals.

It turns out the filters I was using were charcoal filters with a little pad over it, kind of ironic. These are mainly for fumes, I might as well of just had my hand over my face.
