Selenium and its compounds are awful toxic, but the trace selenium are capital nutrients the animal body. Stable in the air, usually absolute 5 baptize of condensate for the conical crystallization, accident of baptize in dry air. The appurtenances stored in a dry, cool, aerial warehouse. Away from fire, calefaction source. Abstain absolute sunlight, packing seal, should acerbic and oxidant,, the use of chemicals stored separately, abstain bond reservoir. Storage areas should be able with the adapted arising accession container. : sealing operation, accommodate acceptable bounded ventilation, to anticipate dust appear into the air in the branch or in the laboratory.
