| Hazards Identification | Back to Contents | 【Inhalation】
May cause methemoglobinemia, cyanosis, convulsions, tachycardia, dyspnea, and death. May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown blood. Inhalation can cause systemic acidosis and methemoglobinemia. | 【Skin】
May cause skin irritation. | 【Eyes】
Causes eye irritation. | 【Ingestion】
Ingestion of large amounts may cause gastrointestinal irritation. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown colored blood. | 【Hazards】
MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO. | 【EC Risk Phrase】
