Animal trials with respirable dust gave some indication of inhalational toxicity, the effects of which were reversible at low concentrations. To alleviate the associated risk, some manufactures supply bismuth vanadate pigments in a free-flowing, low-dusting form, making them inaccessible to the lungs. The safety of these pigments is reinforced by their high density, which causes any airborne dust generated to settle very quickly. Even so, the usual precautions and industrial hygiene rules necessary for handling chemicals must be observed.
