The most common topic request for Safety Week was dust and respirators. So here's a quick review of the dust and fumes that can make our lives miserable in the shop, and why we need respirators for pro-active protection. And below you will find a links to the exact respirator setup I like to use: the 3m 7500 Series. The link below is for large, but you can select a different size here: Small, Medium, Large. And don't forget the upgraded pink filters. Remember, if you want to use these and the vapor cartridges at the same time, you will need a special adapter. I picked mine up locally at a Dunn Edwards store.
