I’m concerned about some of the posts I’ve been seeing over on LE in the past few weeks. I’ve been hoping that “someone” would step in and correct some of the mis-information that is being spread, but evidently he doesn’t care enough to bother. Continue reading
From a post on LE:
We have lived in the same mid century (as in 1963) home for many years. My studio is not original to the house – but claimed from the overhang of the sorta second story when we enclosed the space. Two sides of the room are sliding glass doors. The opposite walls are sheet rock (my supplies) and a brick wall 2/3rds up to a window, where my workbench is located. The problem is (and I’m sure there are many more to come) is that the ceiling is is only about 7 feet. It makes for a very small space to box up all those fumes – even if I have both sets of doors open.
All the “experts” totally blew the answer to this one, mostly I think by not reading the post. Continue reading
Several people in the past couple of days have e-mailed and PM’d me with questions about their own situations where either their significant others or landlords have not allowed them to cut holes in walls or ceilings to allow ventilation. They still want to work safely and have asked me to help them resolve this issue. Continue reading
Many people, some of them fairly influential in the glass-working field, have publicly stated that it is difficult, if not impossible to work in a properly ventilated public studio. These same people have said that it is “OK” to open some windows and doors and use some box fans to move air around, but to also take frequent breaks. As this paper will show, this thinking is short sighted, and ultimately dangerous to the uninformed (especially new students).
This failure to take the initiative in presenting a united front for studio safety has led me to research one of the principle reasons glass-working studios MUST properly ventilate their work areas. That reason is NOx. The chief “bad actor” (as Stan Wolfersberger calls it) of the NOx family is NO2, nitrogen dioxide. Continue reading
By popular request, I’ve added a new page that gives the links to the three articles I’ve written on ventilation. This will make it easier to look up the basic ventilation principles and formulae.
It’s always nice to hear!
The guy was very impressed by your whole design of both the hood and your suggested way I should exhaust, bring in fresh air under bench, etc. as he said it is nice to see someone having a thorough understanding of ventilation needs… that he has never had anyone come into his shop with anything even close to a proper idea of how to ventilate a studio… that artists are the worst of the worst cause you can’t convince them otherwise either!
These questions/comments were gleaned from various forums:
Does it matter how far away the make up air is (as long as it is 10 feet away from the exhaust vent and furnace hot water heater etc.?) Or does it work better if I am on the same side as the open window and therefore closer, but not too close! Continue reading
