Disinfection of heat-sensitive material by low-temperature steam and formaldehyde.
Steam under subatmospheric pressure at temperatures below 90 degrees C. rapidly killed nonsporing organisms after air had been removed by a high-vacuum pump. Most bacterial spores were killed but small proportions of the populations were very resistant. The destruction of spores was not logarithmic. The addition of formaldehyde vapour to the steam greatly increased its sterilizing power, with d...
متن کاملDisinfection of Cystoscopes by Subatmospheric Steam and Steam and Formaldehyde at 80 ° C
The various methods of disinfection at present used for endoscopic instruments include immersion in an antiseptic solution (Miller et al., 1960), pasteurization in water (Francis, 1959), exposure to formalin vapour in a cabinet, and exposure to ethylene oxide. Though certain endoscopes are able to withstand autoclaving, this method cannot be used for all parts of the endoscope or for children's...
متن کاملExperiments on terminal disinfection by formaldehyde vapor in the case of smallpox.
The usually recommended terminal disinfection by formaldehyde vapor is unable to completely inactivate vaccinia viruses embedded in scabs. In view of our results, we recommend doubling the concentration of formaldehyde (10 g of formaldehyde per m3 of space) and prolonging the time of exposure to 24 h for terminal disinfection in the case of smallpox. Subsequent disinfection by scrubbing assumes...
متن کاملFormaldehyde-releasers: relationship to formaldehyde contact allergy. Contact allergy to formaldehyde and inventory of formaldehyde-releasers.
This is one of series of review articles on formaldehyde and formaldehyde-releasers (others: formaldehyde in cosmetics, in clothes and in metalworking fluids and miscellaneous). Thirty-five chemicals were identified as being formaldehyde-releasers. Although a further seven are listed in the literature as formaldehyde-releasers, data are inadequate to consider them as such beyond doubt. Several ...
متن کاملDisinfection of hatching eggs by formaldehyde fumigation – a review Desinfektion von Bruteiern durch Begasung mit Formaldehyd – eine Übersicht
Microbial contamination of hatching eggs is a main concern of poultry producers as it causes poor hatchability and chick performance. It is evident that high standards of hygiene must be practised in hatcheries in order to minimise the soiling of eggs but, further disinfection of eggs is also necessary to limit bacterial numbers. Methods used include the application of disinfectants by wiping, ...
