SOP for Evaluation of Environmental Monitoring Results (Trend Analysis)


Standard operating procedure to evaluate the environmental monitoring results of different area by trend analysis.

1.0  Objective

       To  ensure the corrective action to be taken for the result exceeding alert & action level.

2.0  SCOPE

       This procedure is applicable to evaluate the environmental monitoring results of different area by trend analysis.

3.0  Responsibility

3.1  Doing      : Technical Assistant (Microbiologist)
3.2  Checking : Executive/Manager    

4.0  Accountability

       Head of the Department

5.0  Procedure

5.1  Distinguish  the results in three categories as follows.
       1. Normal level
       2. Alert level
       3. Action level
5.2  No action is required for results observed in normal level and below alert level category.
5.3  Consider the results, observed above normal level and below action level as alert level category.
5.3.1  On alert trend of results inform to Q.A and Production department.
5.4  Initiate the preventive action for any action level or critical results .
5.4.1  In action level results, a deviation report must be submitted to Production, Q.A and Quality control (Microbiological testing lab) and to be involved in deciding action to be taken.
5.5  Evaluate the results and decide that  up to what extent and how much identification is relevant based on comments from production. Identify all micro organisms found in the critical areas up to a level for  determining the origin of the same.
5.6  Send the trend analysis report to QA dept. for evaluation of trend.
5.7  Frequency of trend analysis
