For me things are quite simple. I have a hobby. If I have to read hundreds of pages of legal rules about how to label things, how to store
things, how to use things, and so on, then I have no fun anymore and then I will quit. I use common sense and have taken the following measures:
- fire fighting equipment in the lab (sand, CO2-extinguisher, running water, a blanket). This set can handle many different kinds of fire.
- storage: acids together, oxidizers together, separate from other stuff, corrosive stuff like acyl chlorides together. Bulk amounts of flammables
(liter bottles) are not stored in the lab, but in our garage, which is not in the house. Other chemicals grouped according to some list, so that I can
find them quickly again by looking up the list.
- experimenting: use microscale, test tubes instead of jars. This saves money and produces less waste.
- waste: solvents I evaporate in air, outside. Because I work on a microscale, I seldomly evaporate more than a few ml. Heavy metal waste I collect
and bring to a municipal processing facility. Same for toxic less volatile organics. Rest of waste goes down the drain with lots of water.
- I try to keep my lab clean. No dust on workbenches and floor. Only few open shelves, nearly all my stuff is in a more or less dust-free storage.
With this kind of common sense I can keep my hobby safe and I am doing this already for 30 years or so and never had a bad accident. The worst things
I had were broken glass, little burns on the hand (less than half a square cm) or small cuts from sharp items, while I have been experimenting quite
intensely, at high frequency.
I respect all the effort some members over here put in getting info about all rules, but that is not my thing. If I happened to have a company, making
a profit of my lab, then of course it would be different, but now I just am interested in the science and use common sense and caution when it comes
to safety, clean working and causing as little as possible environmental strain. If authorities really would pursue me and force me to adhere strictly
to all kinds of regulations like REACH, then I will quit and find another science hobby (e.g. electronics, mathematics).
The few chemicals which are not allowed anymore because of the explosives precursors law I do not buy anymore, nor do I have them in stock in bigger
quantities. I can make K/NaClO3 myself by electrolysis, the same for K/NaClO4 from legal NH4ClO4, the same for HNO3 by distillation and I can
concentrate 12% H2O2 to well above 20% without too much trouble. That is enough for me. I work in small scale, so no need for a liter or a kilo of
these chemicals. 50 ml of self-distilled HNO3 or 100 grams of home made KClO3 (from KCl) goes a long way in my lab. The only difficult thing is
CH3NO2, this is not easily made at home. It be so. |
