【Ingestion】

Harmful if swallowed. May cause methemoglobinemia, cyanosis, convulsions, and death. Causes digestive tract irritation. Ingestion may cause weakness, muscular incoordination, fine tremors, loss of reflexes, convulsions and possible death    from circulatory collapse. Ingestion may cause a decrease in blood pressure, rapid pulse and visual disturbances.

【Hazards】

These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite           combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
