Cell-O-Fill

"The perils of epoxy are pretty well known and documented" - Yes.  A good starting point is the MSDS.

Don't forget about the hazards of wood dust some of which can be a carcinogen. Now when we start cutting our expensive marine ply with that waterproof glue, who knows how the hazards add up.

Wear yor dust masks.

An MSDS is useless, unless you have a clue about the chemicals, their affects, the amounts necessary to be harmful, etc. This doesn't mean don't read it, but it does mean some research is probably in order before getting scared.

I know what you are saying Paul. I worked in Medical Device Sales industry for 40 years and am aware that manufactuerers cover their butts on documentation and some of it is blurry and useless. I will say this tho. I started with a good supply of cell-o-fill (sp) and then switched to mostly Colloical Silica (sp) for convenience because if I I needed it it was available locally. Mistake.

I didn't put respirator on for first 9 months of 18 month build. Mistake.

Had I read and believed the MSDS documentation and taken it seriously I would not have done that.

Be careful boys.

An MSDS is useless if you don't read it.

Moving air in the direction you're not breathing is the easiest way to handle dust. This simply means a hooded fan or blower, to cause a negative air flow at the work area. Before dust extraction, I used a 20" box fan with a 18" plastic corrugated hose duct taped to it. The hose was placed next to the work and the fan sucked off the dust as I sanded. It is a pain in the butt to have to move the hose around as you progress with the work, but it will deposit the dust elsewhere, which is a whole 'nother issue.

 

 

A simple dust extraction hose, sucking off dust, near the work.

 

 

Same hose with a hood.

 

 

Get mean and hook up something that can move some air.

 

 

Don't be afraid to make a HOOD, if you need to. A particulate filter and sucking off air, is the easy way.
