Line Clearance What is it and How to Perform One

If you work in a regulated industry, then line clearance is something that you are probably familiar with. It’s an important procedure to avoid cross-contamination, product mislabeling, or other costly errors. But what is line clearance, exactly? And more importantly, how do you perform line clearance in your manufacturing process? 

This article will discuss what line clearance is and how to safely clear the line for the next process. We will also provide some tips for avoiding cross-contamination and product mislabeling. Stay safe and productive by using line clearance procedures in your manufacturing process!


What is Line Clearance?

Line clearance is a systematic process in manufacturing that ensures equipment and work areas are free of products, materials, and documents from a previous process. Line clearance is also important in preparing for the next scheduled process. This procedure is common in manufacturing and regulated industries such as food and beverage, medical devices, and pharmaceuticals. 


How to Perform Line Clearance

A typical line clearance procedure can be broken down into three key parts:

  1. Clearing: the physical removal of all previous products, materials, and documents that are unnecessary for the current or next process.
  2. Cleaning: the drying and disinfection of all surfaces and equipment. The level of cleaning will depend on the product being manufactured and the regulatory requirements for that product. It will also depend on whether the line clearance took place between batches of the same product or during a complete product changeover.
  3. Checking and Verification: a final check to ensure that all surfaces are dry and free of contaminants. This step can also include recalibrating scales or checking the temperature of the work area. Checking and verification are typically done by the line supervisor or quality control department. These relevant people are notified to inspect the line thoroughly. The next scheduled process can only begin once the supervisor or quality manager gives the green light.


To effectively execute line clearance, operators often use line clearance checklists to ensure that all materials from the previous process have been removed and that the line is completely empty before starting the next process.


Why is Line Clearance Important for Manufacturers

Line clearance is an essential process for maintaining the efficiency, quality, and safety of the manufacturing line. At the same time, it also serves as a requirement of ‘Good Manufacturing Practices (GMP)’ within various industries.

The US Food and Drug Administration’s ‘Code of Federal Regulations Title 21‘ states, “Written procedures shall be established and followed for production and process control designed to assure that the drug products have the identity, strength, quality, and purity they purport or are represented to possess.” These procedures shall include the following:

  1. Assignment of responsibility for equipment cleaning and maintenance.
  2. Cleaning, sanitizing, and maintenance schedules.
  3. A detailed description of the methods, materials, and equipment used in cleaning and maintenance operations. It also includes the methods of disassembling and reassembling equipment to ensure proper maintenance and cleaning.
  4. Identification and removal of previous batch materials, products, and documents.
  5. Prevention of contamination for clean equipment prior to use.
  6. A thorough inspection of equipment for cleanliness prior to use.
  7. Record keeping for maintenance, cleaning, sanitizing, and inspection.


Manufacturers that fail to perform and document line of clearance procedures will be subject to regulatory action and hefty fines.
