This post may have been exhausted previously in this forum but I haven't been able to find the info to address my concerns, as yet. My concern is wood dust and the how this affects my spouse. My shop occupies one of three car bays and is walled off from the other two. I have a door to our back yard and a garage door. I will admit that my shop is not always clean and tidy. This past year my wife has developed a chronic cough and though we suspect environmental allergies I am beginning to suspect wood dust as the culprit. My question for the forum members is what you all may be doing in your shops both for your own safety and the safety of exposing your spouses or other family members to shop dust. Do you freely go in and out of your shops into your homes? The best examples I can think of is to use the bathroom or to have a lunch break. I would assume that most of us attempt to knock off the dust we see, but most likely it is impossible to completely eliminate it. I do wear an apron. I have a ceiling mounted dust filter and I also use a Laguna mobile dust collector that gets attached to the various machines in my shop. For my own personal protection I have an air filter mounted in my face shield and I also have a floor box fan, which when the weather is warmer I turn it on and open a door to help to eliminate wood dust. I have also recently placed a dust particle counter in the shop, which I occasionally turn on when I am working. When the weather does not permit the doors to be open it indicates poor air quality, but a few hours after I leave the shop the air quality goes back to excellent range. During warm weather I open doors and run a fan, which allows good air quality. I apologize if my questions are self evident to you, but I don't have the sensitivity to the wood dust that my wife may have and if I am violating a basic tenet of shop safety I wood like to correct it.
