Indoor air pollution of all types is considered one of the most important health hazards of our time. The dramatic rise in the incidence of Asthma is said to be evidence of this. Ceramic arts, crafts, production and lab testing can generate significant dust if it is not managed properly. Ceramic educational programs can come under scrutiny because of dust concerns. Here are suggestions to reduce your exposure and make your workplace safe.
Success? Gauge your progress by turning out the lights and shining a strong flashlight across the room. Or by how many times your air quality monitor triggers.

It is high-level exposure to this kind of dust for many years without adequate protection that causes silicosis. The levels of dust in a typical well-maintained and clean pottery studio come nowhere close to this.
This material storage area employs a rack to keep pails off the floor so the area can be hosed down easily. The materials in each pail are sealed in plastic bags or the pail is covered with a lid.
An example of a custom-made dust collection hood in our repackaging and lab recipe mixing area. The slots along the front suck particles into the duct directly away from the operator's face. Suction comes from a centrifugal exhaust fan downstream where the pipe exits the building, it is driven by a 3/4hp motor (these fans are best at sucking, not blowing, so they need to be located at the exit). About 40 feet of 8-inch heating pipe connects from the hood to a fitting that expands to 12 inches going into the fan. The sliding damper above the hood enables stopping all airflow (to prevent heat loss during cold days). Notice it is located above the scale and heat sealer where most dust is generated during weighing and packaging.
This designation is an international standard for a general purpose respirator to filter out respirable quartz particles (which cause silicosis). Use one of these when working in a area where ventilation is insufficient to remove all of the dust. Use it also in circumstances where there is temporary generation of large quantities of dust. Do not wear this as a substitute for keeping floors and working areas clean.
