are "building materials" short for construction dust? what are we even
taking about here? the most olfactory offensive substances i've encountered
we're compost methane - which has been fairly sever at times.
things we could do:
1) clean bleach all trash/compost bins/buckets
2) sweep & mop all construction areas after work is done for the day.
3) cover all building materials with tarps/cloth
4) set up/install fans/ventilation
5) make sure fans are on prior to events
