1.1 To lay down a procedure for Operation of pass boxes. Equipment identification No QPBM xxxxxx
2.0 SCOPE
2.1 This SOP covers the procedure for operation of Pass boxes and is applicable in microbiology lab.
3.0 RESPONSIBILITY
3.1 Microbiologist
4.0 ACCOUNTABILITY
4.1 Head – Quality Control
5.0 PROCEDURE
5.1 Switch “ON” the power.
5.2 Put ON the toggle switch located in the control box
5.3 RED and GREEN Indicator lamps glow in the control box.
