What is the procedure for fumigation of operation theater?
The procedure for the fumigation of an operating theater typically involves the following steps:
Preparation:
1. Close The OR: Ensure that the operating theater is closed and sealed off from the rest of the hospital to prevent the spread of fumigants.
2. Remove Equipment and Supplies: Remove all unnecessary equipment, supplies, and materials from the OR. This includes surgical instruments, drapes, gowns, and other items that may be affected by the fumigants.
3. Seal Doors and Windows: Seal all doors and windows tightly to create an airtight environment within the OR. Use masking tape or plastic sheeting to cover any gaps or cracks.
4. Place Fumigants: Place the required amount of fumigants, such as formaldehyde or hydrogen peroxide, in designated areas within the OR. Follow the manufacturer's instructions for proper placement and dosage.
Fumigation:
5. Initiate Fumigation: Start the fumigation process by activating the fumigant-releasing devices. Make sure to follow the manufacturer's guidelines for the specific fumigant being used.
6. Leave OR: Once the fumigation process has started, all personnel should evacuate the OR and remain outside until the fumigation is complete.
Aeration:
7. Wait Period: Allow the fumigants to work their effect for the recommended period, usually several hours. Refer to the manufacturer's instructions for the appropriate waiting time.
8. Turn Off Equipment: Turn off all equipment, including air handling systems, in the OR before entering after the waiting period.
9. Open Windows and Doors: Once the waiting period is over, open all windows and doors in the OR to allow for proper aeration.
10. Use Personal Protective Equipment: During aeration, wear appropriate personal protective equipment (PPE), such as masks and gloves, to protect against any remaining fumes.
11. Safety Checks: Conduct safety checks to ensure the OR is free of harmful levels of fumigants before allowing personnel to enter.
Cleanup:
12. Detoxification Procedure: If required, carry out a detoxification procedure as recommended by the fumigant manufacturer to neutralize any residual fumigants.
13. Thorough Cleaning: Thoroughly clean and disinfect the OR to remove any traces of fumigants and ensure it is safe for use. This includes cleaning surfaces, equipment, and the ventilation system.
14. Safety Testing: Conduct necessary safety tests to confirm the OR is safe for patient care.
15. Approval: Only allow re-entry into the OR once it has been deemed safe by the appropriate authorities or safety personnel.
It is crucial to strictly adhere to the recommended procedures and safety precautions provided by the fumigant manufacturer to ensure the effective fumigation and safety of the operating theater. Failure to follow proper protocols can pose health risks to personnel and patients.
