While fumed silica is not classified as a carcinogen, it is an due to its fine particle size. Prolonged or high-level exposure can irritate the respiratory system and eyes. Consequently, safety protocols typically require the use of protective masks and ventilation when handling the dry powder in industrial settings.

) produced through . In this high-temperature process, silicon tetrachloride is vaporized in an oxygen-hydrogen flame, creating microscopic droplets of molten silica. These droplets fuse into branched, chain-like structures called "secondary particles," which then agglomerate into the light, fluffy white powder found in industrial sacks.
