P391: Collect spillage.
P501: Dispose of contents/container to ... 		Although acute toxicity is Category 1 and bio-accumulation is low (BCF=260(Existing Chemical Safety Inspections Data, )), since there was no rapidly degrading (the decomposition by BOD: 0%(Existing Chemical Safety Inspections Data)), it was classified into Category 1.
