Standard Operating Procedure (SOP): Operation of Laboratory Autoclave

Purpose:
The purpose of this Standard Operating Procedure (SOP) is to provide detailed instructions for the safe and effective operation of a laboratory autoclave. This SOP ensures proper sterilization of laboratory equipment, media, and waste to maintain aseptic conditions.

Scope:
This SOP applies to all personnel involved in operating and maintaining the laboratory autoclave in a laboratory or testing environment.

Responsibility:
Laboratory personnel: Responsible for operating the laboratory autoclave as per this SOP.
Laboratory Manager: Responsible for ensuring the availability and maintenance of the laboratory autoclave.
Quality Assurance (QA): Responsible for reviewing and approving this SOP.

Procedure:
4.1. Equipment and Materials:
Laboratory autoclave
Autoclave-compatible items (e.g., equipment, media, waste)
Autoclave bags or containers
Autoclave tape or indicator strips
Personal Protective Equipment (PPE) – lab coat, gloves, safety glasses
4.2. Pre-Operational Preparations:
4.2.1. Ensure that the laboratory autoclave is clean, free from debris, and in proper working condition.
4.2.2. Familiarize yourself with the specific operating instructions and technical specifications provided by the manufacturer for the laboratory autoclave being used.
4.2.3. Check the availability and condition of autoclave-compatible items to be sterilized.
4.2.4. Ensure the availability of suitable autoclave bags or containers, as well as autoclave tape or indicator strips.
4.2.5. Wear appropriate PPE, including a lab coat, gloves, and safety glasses.
4.3. Safety Precautions:
4.3.1. Follow all laboratory safety protocols and guidelines while operating the laboratory autoclave.
4.3.2. Avoid overloading the autoclave beyond its capacity to ensure proper sterilization.
4.3.3. Ensure that the autoclave is placed on a stable surface and properly connected to a reliable power source.
4.3.4. Do not open the autoclave door during operation or while it is under pressure.
4.3.5. Familiarize yourself with the emergency stop or release mechanisms of the autoclave.
4.4. Operation:
4.4.1. Prepare the items to be sterilized, ensuring they are suitable for autoclaving and placed in autoclave bags or containers.
4.4.2. Ensure the autoclave bags or containers are properly sealed, leaving space for steam expansion during the sterilization process.
4.4.3. Place autoclave tape or indicator strips on the outside of the bags or containers to visually indicate successful sterilization.
4.4.4. Load the prepared items into the autoclave, arranging them to allow proper steam circulation and preventing any contact between bags or containers.
4.4.5. Close the autoclave door securely and ensure it is locked in place.
4.4.6. Set the desired sterilization parameters, such as temperature, pressure, and sterilization time, based on the requirements of the items being autoclaved.
4.4.7. Start the autoclave according to the manufacturer’s instructions, and allow it to reach the set temperature and pressure gradually.
4.4.8. Maintain the sterilization conditions (temperature and pressure) for the specified duration.
4.4.9. Once the sterilization process is complete, allow the autoclave to depressurize naturally or follow the manufacturer’s instructions for rapid depressurization, if applicable.
4.4.10. After depressurization, wait for the autoclave to cool down before opening the door.
4.4.11. Carefully open the autoclave door, ensuring there is no residual pressure inside.
4.4.12. Use caution when handling sterilized items as they may be hot. Allow them to cool down before removing them from the autoclave.
4.4.13. Inspect the autoclaved items for any signs of damage or inadequate sterilization. Discard any items that show signs of contamination or are damaged.
4.4.14. Record the sterilization details in a logbook, including the date, time, temperature, pressure, sterilization cycle, items sterilized, and any observations or notes.
4.5. Post-Operational Procedures:
4.5.1. Clean the autoclave chamber, racks, and trays using suitable cleaning agents and following the manufacturer’s instructions.
4.5.2. Empty and dispose of any autoclave waste properly, following laboratory waste management protocols.
4.5.3. Regularly inspect and maintain the autoclave, including cleaning filters, checking gaskets, and scheduling periodic maintenance as recommended by the manufacturer.

Records:
5.1. Maintain a record of each sterilization cycle conducted in the autoclave, including the date, start and stop times, temperature, pressure, items sterilized, and any observations or notes.
