Other Protective Clothing or Equipment:  Normal laboratory gear. Hazard Component: Zinc Sulfide . The structure of Zincblende is simple and consists of the zinc metal-sulfur atom attached to each other via a polar covalent bond. No other chronic effects recorded. Medical Conditions Generally Aggravated by Exposure:  Pre-existing respiratory disorders. Chemical Safety. Hazardous Decomposition Products:  Zinc oxide, sulfur, oxides of sulfur, zinc hydride, and hydrogen sulfide. Avoid dust inhalation and direct skin contact. Structure. Take care not to raise dust. CAS Number: 1314-98-3 II. Zinc sulfide, ZnS, occurs in nature as the mineral sphalerite and may be prepared by treating solutions of zinc salts with hydrogen sulfide. Do not ingest. ZnSO3 or O3SZn. Zinc sulfide – an inorganic compound with the chemical formula ZnS – is a highly purified additive that can be used to enhance coatings and plastics products. NACRES NA.22 var addyc2662c6b3c8b00e91ec4c23d84c39930 = 'sales' + '@'; It consists largely of zinc sulfide in crystalline form but almost always contains variable iron. However, when heated, it evolves a fume of zinc oxide which when inhaled fresh can cause a disease known as “brass founders”, “ague” or “brass chills.”  Zinc oxide dust which is not freshly formed is virtually innocuous.

Do not store together with acids or oxidizing agents. Sphalerite ((Zn, Fe)S) is a mineral that is the chief ore of zinc. Zinc compounds have variable toxicity, but generally are of low toxicity. MDL number MFCD00011301. In luminescence: Sulfide-type phosphors, activators, fluxes. var prefix = 'ma' + 'il' + 'to'; Chronic Effects:  Inhalation:  May cause respiratory tract irritation with nasopharyngitis and laryngitis. Unusual Fire & Explosion Hazards: Zinc sulfide decomposes at temperatures greater than 400 o C in air and/or in oxidizing atmospheres. Formula: ZnS. PubChem CID. Wash thoroughly after handling and before eating or smoking and at the end of the work shift. It is obtained as a white or yellowish-white crystal. ZnS is not harmful to humans but is hazardous to the environment. Miners have also been known to refer to sphalerite as zinc blende, black-jack and ruby jack. Special Fire Fighting Procedures:  Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.
