seems to suggest that the place to go isn't the laser cutter itself, but
the data sheets of the materials you're cutting in it, which the
supplier should provide. I looked up some acrylic sheet providers on the
Internet and they tended to list the contents and consequences of the
fumes released when the product is heated.

http://www.bofa.co.uk/whatIsLaserFume.asp has some good information, but
I don't know how helpful it is.

We should make it clear we don't lase PVC!

Now, lots of people seem to use laser cutters without extra filtering
systems and just vent to the outside world, but I think he'll be more
interested in regulations than in common practice...

It would be nice if we could vent to the roof rather than straight onto
a pavement! Space to dissipate and dilute is a great way to reduce
concentrations...
