| Hazards Identification | Back to Contents | 【Inhalation】
May be fatal if inhaled. May cause respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown blood. This product contains nitrite which may cause methemoglobinemia. Can produce delayed pulmonary edema. | 【Skin】
May be fatal if absorbed through the skin. The toxicological properties of this material have not been fully investigated. Substance is readily absorbed through the skin. | 【Eyes】
May cause eye irritation and possible damage. | 【Ingestion】
May be fatal if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown colored blood. May form methemoglobin which in sufficient concentration causes cyanosis. | 【Hazards】
Containers may explode when heated. | 【EC Risk Phrase】
