■ Unless other proper procedures and control measures have been implemented, dust collection systems should be used in manufacturing and fabrication settings where appropriate and feasible.

■ Exhausted air containing SVFs should be filtered prior to recirculation into interior workspaces.

■ If ventilation systems are used to capture SVFs, they should be checked and maintained regularly.

1. Wear appropriate clothing.

■ Loose-fitting, long-sleeved, and long-legged clothing is recom­mended to prevent irritation. A head cover is also recommend­ed, especially when working with material overhead. Gloves are also recommended. Skin irritation cannot occur if there is no contact with the skin. Do not tape sleeves or pants at wrists or ankles.

■ Remove SVF dust from the work clothes before leaving work to reduce potential for skin irritation.
