The cleaning validation of equipments is a regulatory requirement to ensure that the procedure to remove residues of the product and the cleaning agent to a level of acceptance, ensuring no cross contamination. The analytical methodology chose to monitor the occurrence of cross-contamination was the determination of total organic carbon (TOC) as it is a non-specific technique allowing to quantify the residues before and after the cleaning procedure. For the execution of the validation it was selected the worst case regarding contaminant. The Hib vaccine was chosen as the worst case because it has greater adherence to stainless steel 316L, with a lower percentage of recovery when compared to vaccine meningitis A and C, being respectively 93.0% and 98.4% for the extraction time of 30 seconds and 67.8% and 72.6% for the extraction time of 10 seconds. The considered acceptable product residue in the rinsing water was 0.0007 mg/mL of polysaccharide (0.48 mg/mL of TOC) and in swab it was 0.006 mg/mL of polysaccharide (3.49 mg/mL of TOC). Samples took for determination of residual product has been analyzed and corrected by the recovery factor for this waste water samples by rinsing which is 98.5% and for samples in swab that is 98.4%. The acceptable residue for the cleaning agent (NaOH) was 3.512 mg/mL which provides a pH of 9.94, but there is no evidence that the concentration of residual NaOH does not chemically interfere in contact with the vaccine. Thus, the criterion used was the same as for water for injection, according to USP, that is between pH 5 and 7. Samples took for the determination of residual cleaning agent were not corrected by the recovery factor because the criterion used is much more critical than that calculated. All the analysis results were within the acceptable parameters allowing to conclude that the cleaning procedure for 316L stainless steel tank was effective, removing the waste to acceptable levels, thus, preventing from cross-contamination
