Inhalation

May cause respiratory tract irritation.

Skin

May cause skin irritation. Low hazard for usual industrial handling.

Eyes

May cause mild eye irritation.

Exposure Controls/Personal Protection

Personal Protection

Wear appropriate protective eyeglasses or chemical safety goggles, gloves and adequate protective clothing to minimise skin exposure. Wash hands and face thoroughly after handling and before eating, drinking smoking or using toilet facilities.

Respirators

In dusty conditions, wear a dust mask or air-supplied breathing apparatus depending on levels of dust.

Exposure Effects

Chronic inhalation or ingestion may result in nonspecific neurological symptoms of headache, apathy, and weakness of legs, followed by psychosis, and finally appearing with neurological symptoms similar to those of Parkinson's disease. In its acute form, manganese poisoning has an effect characteristic of other heavy metals, leading to metal fume fever if dust or fume is inhaled in sufficient quantity.
