Fume sizes
A common laboratory module has a width of approximately 10 ft. 6 in. but will vary in depth from 20–30 ft. The depth is based on the size necessary for the lab and the cost-effectiveness of the structural system. The 10 ft. 6 in. dimension is based on two rows of casework and equipment (each row 2 ft. 6 in. deep) on each wall, a 5 ft. aisle ...We would like to show you a description here but the site won’t allow us.NIOSH Respirator User Notice, May 2, 1997.

As shown in the chart above, the sizes of the fume particles that carry hexavalent chromium vary from 5/100 of a micron to 34 microns, and most are in the very small range (sub-micron to 2 microns). It is, therefore, necessary to use filter media in the collection system that can capture a full range of sizes, from sub-micron to large particulate. Heating oil fumes that are detectable by smell are not dangerous. However, odorless carbon monoxide fumes from a heater are dangerous. Detectable fumes do indicate a problem within the heating system that usually requires repair.
The particle size distribution of welding fumes has significance to the deposition in the respiratory tract and the level of toxicity. The size of arc welding fume particles ranges between 0.05 and 20 μm (Zimmer and Biswas 2001). Inhaled particles may deposit throughout the respiratory system or they may be exhaled.
