| [Handling] Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood. | |
| [Inhalation] Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema. Toxic if inhaled. May cause burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Inhalation may cause sore throat, shortness of breath, labored breathing, coughing, and pulmonary edema. | |
| [Skin] May be harmful if absorbed through the skin. Causes irritation with burning pain, scaling, itching and redness. May cause erythema and blistering. | |
| [Eyes] May cause conjunctivitis. Causes redness and pain. Causes eye irritation and burns. May cause permanent corneal opacification. | |
| [Ingestion] May be harmful if swallowed. May cause irritation of the digestive tract and possible burns. May cause nausea, vomiting, headache, cramps, chills and drowsiness. | |
