Any urethane product contains MDI and/or TDI and this includes foam used
in furniture or poly adhesive.

MDI and TDI are both full hazmat chemicals requiring self contained air
supply masks (an air bottle strapped on your back or equal) if are are
near the stuff.

You also need full hazmat suits.

Hmmm, I've never seen Norm in a hazmat suit when doing a glue up. Now, I
don't doubt the chemicals are hazardous in raw form and full concentration,
but what happens when they are cured? MSDS sheets are good for raw
chemicals, but they are of little or no value once the chemical has been
processed, combined, cured, dried, whatever.

Ever notice that once wood is fully oxidized in becomes fireproof?
