Base on the QHSE of chemicals used in the oil and gas field,in order to prevent the oil and gas field from polluting,the toxicity of the chemicals testing on mice was studied.The acute oral toxicity of CPI-5 corrosion inhibitor on mouse was tested by a disposable dosage giving chemical after giving chemical 7-days and continuous observation on mousse carried out for the minimum lethal dose median lethal dose analysis of CPI-5 corrosion inhibitor.The result shows that the minimum lethal dose LD50 of CPI-5 corrosion inhibitor were about 14.9g/kg weight and 30.45g/kg weight,so CPI-5 corrosion inhibitor was defined as non-toxic or low toxicity,and it could be widely used in oil and gas field.Due to the non-tixic or low toxicity of the corrosion inhibitor in the oil and gas field,it was very important to operation environment and healthy of employees.
