Sterilization of the biological safety cabinet. 1974

S W Newsom, and B M Walsingham

Test strips comprising B subtilis spores or M phlei cells dried on aluminium foil (some serum-coated) were used to test sterilizing processes currently advised for safety cabinets. Exposure to formalin from a bowl, boiling excess formalin with the fan running, and ultraviolet radiation were all found to be unreliable, as was glutaraldehyde. Vaporization of 2 ml of formalin per 0.028 m(3) followed by exposure for 18 hours at ambient temperatures was 100% successful, and the depolymerization of paraformaldehyde tablets with a hair drier was a simple, very effective alternative method.

UI	MeSH Term	Description	Entries
D007753	Laboratories	Facilities equipped to carry out investigative procedures.	Laboratory
D009161	Mycobacterium	A genus of gram-positive, aerobic bacteria. Most species are free-living in soil and water, but the major habitat for some is the diseased tissue of warm-blooded hosts.	Mycobacteria
D010242	Paraldehyde	A hypnotic and sedative with anticonvulsant effects. However, because of the hazards associated with its administration, its tendency to react with plastic, and the risks associated with its deterioration, it has largely been superseded by other agents. It is still occasionally used to control status epilepticus resistant to conventional treatment. (From Martindale, The Extra Pharmacopoeia, 30th ed, p608-9)
D011482	Protective Devices	Devices designed to provide protection against injury.	Safety Devices,Device, Protective,Device, Safety,Devices, Protective,Devices, Safety,Protective Device,Safety Device
D004202	Disinfectants	Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed)	Biocide,Disinfectant,Biocides
D004864	Equipment and Supplies	Expendable and nonexpendable equipment, supplies, apparatus, and instruments that are used in diagnostic, surgical, therapeutic, scientific, and experimental procedures.

D005557	Formaldehyde	A highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p717)	Formalin,Formol,Methanal,Oxomethane
D005976	Glutaral	One of the protein CROSS-LINKING REAGENTS that is used as a disinfectant for sterilization of heat-sensitive equipment and as a laboratory reagent, especially as a fixative.
