|Solvent canisters may only be filled up to that height! There must still be a little bit air in the canister!|
The air buffer is essential!
Wow! But safety is first! And if substance is spilled from an overfilled canister this may be even more expensive...
My waste is only a very little bit. This will still fit.
... And my waste then will also fit.
The last two times it was me who took away the full canister. I would not dream to become the lackey of the others.
I found the canister still beeing overfilled. Therefore it does not matter if it is now a little bit more overfilled with my waste.
Why should I take care about the filling height!
