Annex 3 - Cleaning Validation Guidelines
Cleaning validation is the process of establishing documented evidence which provides a high degree of assurance that a particular cleaning procedure will consistently produce results that meet pre-determined acceptance criteria.
A cleaning validation program should be commensurate with the complexity of the manufacturing process and the cleaning requirements. The program should also be based on the product's intended use and the results of any cleaning validation studies that have already been conducted.
The following are general principles that should be followed when developing and conducting a cleaning validation program:
1. A thorough understanding of the manufacturing process and the cleaning requirements should be established.
2. A risk assessment should be conducted to identify potential hazards and determine the appropriate level of cleaning validation.
3. Cleaning validation studies should be designed to assess the efficacy of the cleaning procedure under worst-case conditions.
4. Studies should be conducted using representative cleaning challenges (e.g., soils, residues, etc.) that are representative of those expected to be encountered in actual use.
5. Acceptance criteria should be established prior to conducting the study.
6. Studies should be conducted in accordance with GLP principles.
7. Results of the studies should be analyzed and interpreted using statistical methods.
8. A comprehensive report documenting the study results should be prepared.
The Cleaning Validation Guidelines provide specific guidance on the design, conduct, and analysis of cleaning validation studies. In addition, the Guidelines provide general information on the cleaning validation process, including risk assessment and cleaning validation program management.
What is the purpose of cleaning validation guidelines appendix 3?
Cleaning validation guidelines appendix 3 is a set of procedures and guidelines to be followed during the validation of cleaning processes. It provides a detailed description of how to validate a cleaning process, including rinse volumes and number of cleanings required. Additionally, it outlines the responsibilities of both the manufacturer and the customer during cleaning validation. By following these guidelines, manufacturers can ensure that their products meet the highest standards of quality and safety.
Who is responsible for ensuring compliance with cleaning validation guidelines appendix 3?
Compliance with cleaning validation guidelines is the responsibility of the manufacturers of products that require cleaning. This appendix provides guidance on how to validate the cleanliness of products that come into contact with food.
Cleaning validation is important because itensures that food products are not contaminated with harmful bacteria or chemicals. Manufacturers must establish and follow cleaning procedures that are effective in removing all possible contaminants from their products. These procedures must be validated to ensure that they are effective in removing all contaminants that could potentially be present.
There are three main types of cleaning validation: product contact cleaning, non-product contact cleaning, and environmental monitoring. Product contact cleaning involves the cleansing of all surfaces that come into direct contact with the food product. Non-product contact cleaning involves the cleansing of all surfaces that come into indirect contact with the food product. Environmental monitoring involves the testing of surfaces and areas for the presence of contaminants.

In order to ensure compliance with cleaning validation guidelines, manufacturers must establish and follow effective cleaning procedures. These procedures must be validated to ensure that they are effective in removing all contaminants that could potentially be present.
What products are subject to cleaning validation guidelines appendix 3?
Products that are subject to cleaning validation guidelines appendix 3 include but are not limited to: medical devices, pharmaceuticals, cosmetics, food contact surfaces, and sterilized surfaces. The guidelines outline requirements for cleaning validation, including specifying the cleaning method, defining when cleaning is necessary, demonstrating the efficacy of the cleaning method, and documenting the results.
What methods are used to validate cleaning procedures under appendix 3?
There are many methods used to validate cleaning procedures under appendix 3. The most commonly used validation method is the determination of maximum residue limits (MRLs). MRLs are the highest amount of residue that can be present on a food surface and still be considered safe. In order to determine an MRL, laboratory testing is conducted using a variety of food simulants. The results of these tests are then used to calculate an MRL.
Other methods used to validate cleaning procedures under appendix 3 include:
-Visual inspection -Aministrative review -Cleaning verification by analytical methods -Swabbing
Visual inspection is often the first step in validated cleaning procedures. It is a simple and quick way to identify potential problem areas. Administrative review is another common method used. This involves reviewing all cleaning procedures and documentation to ensure that they are adequate.
Cleaning verification by analytical methods is the most reliable way to validate cleaning procedures. This involves testing food surfaces after they have been cleaned to confirm that residues have been removed. Swabbing is a less common method, but it can be used to identify problem areas. Swabs are taken from food surfaces and then analyzed in a laboratory.
What are the acceptance criteria for cleaning under appendix 3?
The cleaning acceptance criteria for appendix 3 are:
1. All areas must be cleaned to a high standard 2. All areas must be free of dirt, dust and debris 3. All surfaces must be cleaned and disinfected 4. All areas must be free of bad odors 5. All areas must be free of clutter and well-organized 6. All areas must be safe and hazard-free
What are the consequences of failing to meet the requirements of appendix 3?
If the requirements of appendix 3 are not met, the consequences can be very serious. The most immediate consequence is that the project will not be able to proceed as planned. This can lead to significant delays and cost overruns, as well as jeopardizing the safety of the workers and the public. In addition, failing to meet the requirements of appendix 3 can also lead to legal liability. If there are accidents or injuries that occur as a result of the failure to meet the requirements, the company could be sued. In some cases, the company might even be criminally liable.
How often must cleaning validation be conducted under appendix 3?
Cleaning validation must be conducted at least annually, and more often if there are process changes that could affect the cleaning process.
What records must be kept for cleaning validation under appendix 3?
Appendices 3 and 4 to part 11 of 21 CFR detail the United States Food and Drug Administration's (FDA) specific requirements for what records must be kept during and after cleaning validation under cGMP.
The purpose of cleaning validation is to ensure that products do not become contaminated during manufacture. Good manufacturing practices (GMPs) require that manufacturers establish and follow written procedures to clean their facility and equipment and to validate the effectiveness of the cleaning procedures.
Validation of cleaning procedures is necessary to ensure that deposited soils are removed and do not interfere with subsequent product fabrication or adversely affect product quality. Validation demonstrates that the cleaning process can consistently clean to an acceptable level and is a prerequisite to process validation.
Areas of a facility that must be cleaned and for which cleaning validation must be conducted include, but are not limited to, the following:
- Production areas - Storage areas - Testing and quality control laboratories - Utilities (e.g., water, compressed air, vacuum, and gases) - Waste disposal areas
Cleaning validation should be conducted under actual production conditions.
Cleaning validation studies should include, but are not limited to, the following elements:
- Description of the product(s) to be manufactured - Description of the manufacturing process - Description of the cleaning process - Description of the test methods - Identification of critical surfaces -Establishment of acceptable limits - Number of cleaning validation runs - Analyses of samples from each surface to be cleaned
Samples should be collected from all critical surfaces prior to and after cleaning. Analyses of these samples should be conducted using methods that are sensitive enough to detect the soil at the levels established as acceptable.
Samples should be collected in a manner that will prevent contamination of the surfaces being sampled. Swabbing, sonication, or other methods may be used to collect samples from small surfaces. For larger surfaces, a wipe technique or other means may be used.
Cleaning validation should be conducted periodically to verify that the cleaning process is effective and that no significant changes have occurred that could affect the cleaning process. These periodic validation studies should be conducted at a frequency that is appropriate for the products being manufactured and the changes that have occurred in the manufacturing process.
The results of cleaning validation studies should be documented and should include, but are not limited to, the following information:
How should changes to cleaning procedures be handled under appendix 3?
Appendix 3 of thelinebreaks down the procedures for making changes to the cleaning staff schedule. The first step is to consult with the line manager, who will then determine if the change is feasible. If the change is approved, the next step is to submit a written request to the cleaning staff supervisor. The supervisor will then schedule a meeting with the cleaning staff to discuss the proposed change. If the cleaning staff agrees to the change, the supervisor will submit a revised cleaning schedule to the line manager. If the change is not approved, the cleaning staff supervisor will notify the line manager in writing.
Frequently Asked Questions
What is the who cleaning validation guideline?
The guideline is a set of recommendations to help ensure the quality, accuracy and validity of cleaning procedures used in pharmaceutical manufacturing.
What are the requirements for revalidation of cleaning procedures?
The requirements for revalidating cleaning procedures depend on the level of similarity between the cleaned product and the process that cleans it. For very similar products and processes, a validation study of the “worst case” may be considered acceptable. There should be a justified validation programme in place to ensure that the revalidation is accurate and does not introduce any unnecessary variability into the system.
Is there a need for revision of the who guidelines?
There is a need for revision of WHO guidelines as the current quality system does not always ensure the safe and effective use of medicines.
What is the APIC cleaning validation guideline?
The APIC cleaning validation guideline is a document that sets out the minimum requirements for validation of cleanliness procedures at active pharmaceutical ingredient (API) plants. It is intended to complement other guidance documents, such as the EMA's HBELs guidance.
What is cleaning validation and why is it important?
Cleaning validation is an evidence to verify that the procedures used to clean the product residue from equipment and components will consistently & significantly reduce the amount of active ingredient, Excipients and cleaning agent to a concentration within calculated acceptance criteria. Cleaning validation is particularly important when engineering and manufacturing processes involve the use of high concentrations or sensitive substances. In addition, cleaning validation can also be used as part of process development to ensure that formulated products meet specified purity and composition requirements.
