1. Purpose

The purpose of this SOP is to outline the procedures for environmental cleaning of capsule manufacturing areas. This process ensures that the manufacturing environment remains free from contamination and complies with Good Manufacturing Practices (GMP). Environmental cleaning is essential for maintaining product quality and preventing cross-contamination between batches.

2. Scope

This SOP applies to all areas in the capsule manufacturing department, including the production floor, packaging areas, equipment storage areas, and other critical zones. It defines the steps for cleaning the surfaces, floors, equipment, and surrounding environments after each production cycle to meet cleanliness standards.

3. Responsibilities

4. Accountability

The Capsule Manufacturing Supervisor is responsible for overseeing the environmental cleaning process and ensuring that it is carried out according to this SOP. The QA Manager ensures that the process meets GMP standards and that the cleaning records are properly maintained.

5. Procedure

5.1 Preparation for Environmental Cleaning

Before starting the cleaning process, complete the following steps:

  1. Turn Off All Equipment
    1. Ensure that all capsule manufacturing equipment is turned off and disconnected from the power supply to avoid electrical hazards during cleaning.
    2. Confirm that no materials or capsules are left in the manufacturing area.
  2. Gather Cleaning Materials
    1. Collect all necessary cleaning agents, such as detergents, disinfectants, and water, along with PPE (Personal Protective Equipment) required for the cleaning staff.
    2. Ensure that all cleaning agents are compatible with the surfaces being cleaned and are effective in removing contaminants.
  3. Inspect the Area
    1. Inspect the manufacturing area for any visible contamination, residue, or debris. Pay close attention to areas where materials may have spilled or accumulated.
    2. Ensure that cleaning supplies are in good condition and ready for use.
  4. Prepare Cleaning Log
    1. Prepare the Cleaning Log (Annexure-1) to document the cleaning process, including operator details, areas cleaned, and cleaning times.

5.2 Environmental Cleaning Process

Follow these steps for environmental cleaning:

  1. Initial Rinse
    1. Rinse the area and equipment with warm water to remove any loose dust, powders, or residues from the surfaces.
    2. Ensure that all surfaces are thoroughly rinsed, including equipment, floors, and walls.
  2. Apply Cleaning Solution
    1. Apply an appropriate cleaning solution to all surfaces, including walls, floors, and equipment, and allow it to sit for the required time to break down any contaminants.
    2. Use soft brushes or sponges to scrub areas that may have built-up residues or sticky materials.
  3. Rinse with Clean Water
    1. After the cleaning solution has been applied and scrubbed, rinse the area thoroughly with clean water to remove all cleaning agents and debris.
    2. Ensure that the rinse water is effectively drained and does not cause pooling in the cleaning area.
  4. Disinfection (If Required)
    1. If needed, apply an appropriate disinfectant to the area and allow it to sit for the required time to eliminate microbial contamination.
    2. Follow the manufacturer’s instructions for proper use and dilution of the disinfectant.
  5. Final Rinse
    1. Perform a final rinse with clean water to remove any disinfectant residues and cleaning agents.
    2. Ensure that all surfaces are thoroughly rinsed and no cleaning agents remain in the manufacturing area.

5.3 Drying the Manufacturing Area

Once the cleaning process is complete, the area should be dried:

  1. Dry the Surfaces
    1. Wipe down all surfaces with clean, dry, lint-free cloths to remove any excess water.
    2. If necessary, allow the area to air dry to ensure that all surfaces are completely dry before reassembling or starting the next production batch.
    3. Use fans or air dryers to speed up the drying process in large or hard-to-reach areas.

5.4 Post-Cleaning Inspection

After cleaning and drying, perform the following checks:

  1. Inspect for Residual Contamination
    1. Inspect the area and equipment for any remaining cleaning agents, dust, or debris. If contamination is found, repeat the cleaning process.
  2. Check for Proper Drying
    1. Ensure that the surfaces are completely dry and free from any water or cleaning solution residues.
  3. Test for Equipment Functionality
    1. Ensure that all equipment is reassembled, if necessary, and fully functional before the next production cycle begins.

5.5 Documentation

Ensure that all actions are properly documented for traceability and compliance:

  1. Complete Cleaning Log
    1. Record all cleaning actions, including operator details, cleaning times, areas cleaned, and any deviations from the standard procedure in the Cleaning Log (Annexure-1).
  2. Post-Cleaning Inspection
    1. Document the results of the post-cleaning inspection in the Equipment Inspection Log (Annexure-2).
