Fumigation of the Operation theatre shall be done in the following circumstances:
Newly constructed / repair activity undertaken recently in that area
In any other circumstances where need to fumigation is felt e.g. after surgery on infectious cases or major body spills like faecal matter.
Routinely: once a month depending on the nature of civil infrastructure, no of surgical case load and movement of staff and equipment.
In all circumstances proper cleaning, carbolization and spraying should be carried out. For effective fumigation, humidity of the area to be fumigated shall be very high
Before fumigation:
Remove any contamination with 1% chlorine solution and any other article that is likely to be damaged by fumigation
Clean OT properly by washing the room (floor and walls) with soap and water.
Then fumigate
Method of fumigation
Step 1: Preparation
Clean the area (windows, doors floor, walls, surgery table and all washable equipments)thoroughly by with soap and water
Close windows and ventilators tightly. If any openings found seal it with cellophane tape or other material to avoid the leak of fume.
Switch off all lights, A/C and other electrical & electronic items.
Calculate the room size (surgical theatre only) in cubic feet (LxBxH) and calculate the required amount of formaldehyde as given in step 3.
Step 2: Precaution
Adequate care must be taken by wearing cap, mask, foot cover, spectacle etc.,
Formaldehyde is irritant to eye & nose; and it has also been recognized as a potential carcinogen.
So the personnel undertaking the fumigation must be provided with the personal protective equipment (PPE).
Paste a warning notice on the front door indicating fumigation is in progress.
Step 3: Fumigation
Electric Boiler Fumigation Method (Recommended): For Each 1000 cubic feet, 500 ml of formaldehyde (40% solution) added in 1000 ml of distilled water (if not available use tap water) in an electric boiler. Switch on the boiler, leave the room and seal the door. After 45 minutes (variable depending to volume present in the boils apparatus/its heating proficiency) switch off the boiler without entering in to the room (Switch off the main electrical supply from outside).
After the initiation of formaldehyde vapor, immediately leave the room and seal it for at least 12 to 24 hours.
Step 4: Neutralization
Before neutralization, formaldehyde fumigation system should be taken out from the surgical theatre. Then the toxicity of formaldehyde vapor should be neutralized with ammonia solution.
Place a cotton ball and pour 300 ml of 10% ammonia (for each 500 ml of formaldehyde used) on the floor of surgical theatre, at least 4 hours before the “Sterility Test”.
Formaldehyde gas reacts with ammonia gas and produce Hexamine (synonym Hexamethylene tetramine) which is a harmless substance.
Switch on the A/C, at least 2 hours before (09 a.m.) the “Sterility Test”.
