Causes burns.
Risk of serious damage to eyes.
The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion. Ingestion of low-molecular organic acid solutions may produce spontaneous hemorrhaging, production of blood clots, gastrointestinal damage and narrowing of the esophagus and stomach entry.
The material can produce chemical burns to the eye following direct contact. Vapors or mists may be extremely irritating. If applied to the eyes, this material causes severe eye damage. Solutions of low-molecular weight organic acids cause pain and injuryto the eyes. The material may be irritating to the eye, with prolonged contact causing inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.
Skin contact with the material may damage the health of the individual; systemic effects may result following absorption. The material can produce chemical burns following direct contactwith the skin. Toxic effects may result from skin absorption. The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin.
If inhaled, this material can irritate the throat andlungs of some persons. Inhalation hazard is increased at higher temperatures. The material may produce respiratory tract irritation, and result in damage to the lung including reduced lung function.
Principal routes of exposure are by accidental skin and eye contact and by inhalation of vapors especially at higher temperatures. No human exposure data available. For this reason health effects described are based on experience with chemically related materials. As with any chemical product, contact with unprotected bare skin; inhalation of vapor, mist or dust in work place atmosphere; or ingestion in any form, should be avoided by observing good occupational work practice.
