Your job duties as a cleaning validation consultant revolve around helping pharmaceutical companies clean equipment and remove residue from surfaces after production runs for pharmaceutical products. Your responsibilities include inspecting equipment and assisting manufacturers to prevent cross-contamination. You provide advice on how to improve their purification process in a way that does not interfere with the chemical makeup of their medicines. You may help companies establish clean-in-place (CIP) or sterilization-in-place (SIP) procedures. You test these procedures and approve, alter, or enhance them based on your findings.
