Instructional Laboratory Safety Procedures

The following procedures are for use by authorized students, faculty and staff involved with laboratories maintained by the Electrical Engineering Department for instructional purposes.

The course instructor or laboratory supervisor has final responsibility for the safety of all students working in the laboratory under their supervision. The instructor has the obligation and authority to enforce all approved safety procedures in effect at the time.

Individuals operating any piece of equipment in any of the department teaching laboratories will adhere to all current safety and barrier requirements. Students and faculty are responsible for reading, understanding and following all safety procedures posted on the departmental web site, in the laboratories or on specific pieces of equipment that they use.

Teaching laboratories in the Electrical Engineering Department are normally closed and locked when not in use for scheduled labs. Students are not permitted unsupervised access to the lab facilities without permission.

The following procedures and practices only apply to Laboratory Facilities operated by the Electrical Engineering Department of Arkansas Tech University for Supervised Instruction associated with established laboratory courses, or to students enrolled in a laboratory course who have the permission of the instructor to work without supervision.
