In Reply to: Question: How safe is fiberglass in ported speakers? posted by brewthunda on September 19, 2001 at 11:18:46:
that inhalation of fiber glass fibers is not a significant health risk unless you inhale large portions on a routine basis (ie you mfg the stuff or you are an insulation worker) OR you inhale quantities of very small respirable fibers. Fiber glass fibers (unlike some others) are shaped like a glass rod and break cleanly which reduces the damage when breathed into the lung. They are also more soluble in the lung that other mineral fibers.Best practice exposure guidelines allow 5 milligrams of inhalable fibers per cubic meter of air breathed on average over an 8 hour workday for a forty hour workweek over the course of a working lifetime. Thats quite a few fibers! I seriously doubt you would have any exposure concern from the relatively minor disturbance of air movement through a port. So the good news is that you should'nt have to don a respirator during those heavy bass passages!
Bet you never thought you see a toxicologist on the asylum! Happy building.
