It rather depends on your local environmental laws.
The COSHH (Control of substances hazardous to health) data sheet (A legal
requirement in the uk), provided by RS Components, http://RSWWW.com, (No
that's not an error) says the following:
Accidental spillage - collect and reclaim ... dispose ..... licensed
waste. Flush area with plenty of water
<my comment> no warning about preventing above water entering drain.
Ecological information - not regarded as dangerous for the environment
Disposal - In accordance with local authority requirements.
I have a feeling, though I could be wrong, that it used to say something
like "small quantities can be disposed of via the drain if flushed (or was
it diluted) with copious quantities of water.
I think I would probably take that as "the sort of quantities hobbyists
are likely to be dealing with can be poured down the drain if plenty of
water is put down there too.
Unless of course anyone knows any difference......
