Avoid performing experiments alone in a laboratory building. Arrange with individuals working in separate laboratories outside of working hours to cross check periodically. Alternatively, UNC Police can check on laboratory workers. Do not undertake experiments known to be hazardous when alone in a laboratory.

Under unusual conditions, special instructions may be necessary. The Principal Investigator must determine whether the work requires special safety precautions, such as having two persons in the same room during a particular operation.
