Tributyl Phosphate (TBP) - Safety
Open Data Verified Data
rat oral LD50: 3.0g/kg. It has a strong stimulating effect on the skin and respiratory tract, and has a systemic toxic effect. It has mild inhibitory effect on cholinesterase in human blood and plasma. In case of high heat, open flame or contact with oxidant, there is a risk of combustion. Decomposition by heat produces highly toxic phosphorus oxide flue gas. Store in a cool, ventilated warehouse. Keep away from fire and heat source. Keep the container sealed. Should be stored separately from the oxidant, acid, alkali.
