One of the bottles containing Isopentyl Acetate was labeled as "Avoid Problems - Ask." Picture 38 - UPR CIVIL ENGINEERING- At the Lab CI 018 EPA Inspectors observed numerous expired chemicals (since < 1986), discarded, contaminated, various unused chemical reagents, deteriorated and stored for a long time in shelves without physical protection each other from incompatibility characteristics. Picture 39 - UPR CIVIL ENGINEERING - At the Lab CI 018 all these chemical reagents were not in use, expired and discarded a long time ago from various laboratory research and were stored in this area and never declared as "solid waste material," or notified to the OPASO for final disposition. Picture 40 - UPR CIVIL ENGINEERING - At the Lab CI 018 there was no hazardous waste determination being performed on abandoned, expired, not in use, discarded hazardous chemical waste inventory before its final disposal nor have been managed under the Laboratory Management Plan.
