Wash your hands thoroughly with soap and water, following the steps recommended by the World Health Organization.
Wipe your hands with a clean towel or air-dry. Avoid using shared towels, to prevent contamination.
Wear sterile gloves on both hands before starting the procedure.

Perform handwashing before and after examining each woman.

Make sure to always wear gloves before making contact with any secretions, body fluids, or blood.

Change gloves after completing each examination, to prevent cross-contamination.

Arrange the sterile or HLD instruments on the instrument tray.
During the examination, maintain a unidirectional flow of instruments and consumables:

Pick up sterile instruments from the instrument tray.
Examine the woman on the examination table.
Place the used instruments in a separate bowl or container with 0.5% chlorine solution.
Place the used cotton swabs and gloves in a separate bowl or waste disposal container.

Soak the used instruments and other items in 0.5% chlorine solution for 10 minutes. (It is important to remove the instruments from the chlorine solution after 10 minutes, to prevent corrosion and discolouration.)
Remove the instruments from the chlorine solution and wash them thoroughly under running tap water and then place them in detergent solution.
Clean the instruments gently by scrubbing them with a soft brush to remove any organic material, tissue, and blood. Particular care should be given to the curved inner edges, joints, and screws of self-retaining specula, where organic material may remain adherent along with the microorganisms trapped inside.
Rinse all instruments thoroughly with clean water to remove any detergent residues.
Sterilize the instruments by using high-pressure saturated steam (autoclaving), by using dry heat, or by soaking the instruments in chemicals such as 2–4% glutaraldehyde or 8% formaldehyde. If chemical sterilization is used, rinse all instruments with sterile water before use.
If performing HLD by boiling:

Submerge the cleaned instruments in water in a covered pot or sterilizer.
Heat the water to a rolling boil, and keep the instruments in boiling water for 20 minutes.
Do not add any instruments after the water starts boiling.

Soak the cleaned instruments in 0.1% chlorine solution or in 2% glutaraldehyde solution for 20 minutes.
Rinse the instruments thoroughly with sterile water before use.

Dispose of all items contaminated with blood and body fluids, including cotton balls, cotton swabs, and gauze, in properly marked leak-proof containers or plastic bags. Other waste materials generated from the cleaning of clinic premises and disinfection activities should also be discarded in the container or bag.
Send the leak-proof container or bag for incineration or appropriate disposal. (Arrange for daily collection of wastes from screening clinics.)
Decontaminate all objects (e.g. focusing lights) and surfaces (e.g. the examination table) that have come into contact with body fluids and secretions, by wiping them with 0.5% chlorine solution or 90% ethyl alcohol.
Immerse both gloved hands in 0.5% chlorine solution briefly, and remove the gloves by turning them inside out.
Decontaminate the used gloves by soaking them in 0.5% chlorine solution for 10 minutes.
