 Titrating Oil - Collaborative Biodiesel Tutorial
The way this particular titration is written, every 1 ml titration result (ie the acid number) will tell us to add an extra 1 gram of lye for each liter of oil/ffa you're using to make biodiesel to compensate for the side reaction caused by the FFA.
A blank titration neutralises any acids that the isopropyl contained, so you're starting with a 'blank' slate and your real titation only reads the free fatty acids instead of the acids in the isopropyl.
If the isopropyl only needed 5 or 10 drops of lye/water solution to neutralize the acids, don't worry abut repeating this test for the next few titrations- it's not very acidic.

 UpToDate Isopropyl alcohol intoxication
Isopropyl alcohol (isopropanol, 2-propanol, propan-2-ol) is commonly used as a disinfectant, antifreeze, and solvent, and typically comprises 70 percent of "rubbing alcohol." People ingest isopropyl alcohol to become intoxicated (ie, ethanol substitute) or to harm themselves.
Fatality from isolated isopropyl alcohol toxicity is rare, but can result from injury due to inebriant effects, such as untreated coma with airway compromise, or rarely, cardiovascular depression and shock following massive ingestion.
Isopropyl alcohol is a sedative-hypnotic agent whose toxicity closely resembles that of ethanol, with which it shares strong structural similarity.
