Nickel Refinery Dust

Smelting/refining steps like roasting, smelting, crushing, and electrorefining; fugitive emissions and tracked dust around refineries [1][2].

Breathing workplace air; dust on skin or clothing; contaminated indoor dust or soil near facilities; downwind air during operations [1][3].

Known human carcinogen (lung, nasal); can irritate eyes/airways, worsen asthma, and trigger nickel allergy/dermatitis [1][2][3].

Nickel refinery and maintenance workers; contractors; people living close to smelters/refineries; those with asthma or nickel allergy [1][3].

At work: enclosure and local exhaust, wet methods, respirators as needed, wash/shower and change before going home, launder uniforms on-site. At home near facilities: keep dust out with HEPA filtration and wet cleaning, avoid bare-soil tracking, close windows on dusty days, follow local air advisories [3][4].
