: I work in a shop which is 35 x 40 feet. I have built numerous cedar strip
: canoes etc. etc. I have started building hardwood strip hull & ribbed
: kayaks with treated canvas top, but I'm getting in trouble with WHMIS
: because of the dust. I have been doing this kind of work for over 25
: years.

: I believe in an open door policy which is an 8 x 10 garage door on each end
: of my shop. When I am ripping hardwood both doors are wide open to get rid
: of the dust. I have asked & asked but nobody can give me the parts per
: million before sawdust becomes explosive with the flow through ventilation
: that I have. Why is this not safe?

: Parts per million (what would it look like?) I have no idea, I would like
: some information because I cannot afford a dust extraction system.

: Thank you. Jake

I would imagine it would have to be pretty thick to explode that way, and would be unbreathable or visually unworkable. Best guess would be to call or visit your local fire department and ask those fellows there. I'm sure they would much rather stop a fire with info, than their hard work, sweat and blood. Hope that helps!
