Operation Theater Fumigation
Fumigation Procedure by Urban Pest Control Ltd.
Formaldehyde vapor is an extremely effective biocidal agent. It acts as an alkylating agent, inactivating micro-organisms by reacting with carboxyl, amino, hydroxyl and sulphydral groups of proteins as well as amino groups of nucleic acid bases. Fumigation is effective at above the temperature of 20ºC and relative humidity of 65%.
Formalin is commercially available as 40% solution of formaldehyde in water. When formalin is heated formaldehyde vapor is generated. Formaldehyde is a Schedule 1 chemical under the COSHH (Control of Substances Hazardous to Health) Regulations and has a Maximum Exposure Limit (MEL) of 2 ppm. But, concentrations encountered during fumigation is many hundred times higher than this, so fumigation procedure must be carried out only by trained personnel under strictly defined conditions. All workers using formaldehyde must be aware of safe handling procedures.
Under certain conditions formaldehyde can react with hydrochloric acid and chlorine containing disinfectants such as hypochlorites to form chlormethyl ether, a potent lung carcinogen. So hydrochloric acid and chlorine-containing disinfectants must be removed from the room before fumigation.
Step a: Preparation
Step b: Precaution
Step c: Fumigation
Step d: Neutralization
Surgical Theater Volume = L×B×H = 20 × 15 × 10 = 3000 cubic feet
Note: Make it into nearest 1000, if the volume is in fractions
Formaldehyde required for fumigation = 500 ml for 1000 cubic feet
= So, 1500 ml of formaldehyde required (to be diluted in 3000 ml of distilled water)
Ammonia required for neutralization = 300 ml of 10% ammonia for 500 ml of formaldehyde
= So 900 ml of 10% ammonia required
