==Health Hazards of Wood Dust ==
==Health Hazards of Wood Dust ==
Exposure to wood dust has long been associated with a variety of adverse health effects, including dermatitis, allergic respiratory effects, mucosal and nonallergic respiratory effects, and cancer. Contact with the irritant compounds in wood sap can cause dermatitis and other allergic reactions. The respiratory effects of wood dust exposure include asthma, hypersensitivity pneumonitis, and chronic bronchitis.

==Particle Monitoring ==
The most hazardous dust particles are too small to be seen. To determine the effectiveness of the collection system, we will use a relatively inexpensive laser particle counter, such as: http://www.dylosproducts.com/dcproairqumo.html

This will help us fine tune the collection system and tell us when there is insufficient flow due to duct blockage or dirty filters.

==Goals==
Achieve better air quality inside the shop than outside.
1000 CFM for each machine in operation.
4000 FPM air flow in horizontal ducting.
Meet OSHA limits for wood dust (not that we have to - just because it is a good idea).
