urticaria: formal term for hives erythema: formal term for redness high-efficiency particulate air masks (HEPA masks): masks designed to filter out small particles such as the Mycobacterium tuberculosis Spaulding Classification of Inanimate Objects: scale to categorize objects as critical, semicritical, or noncritical critical: items that penetrate or touch broken membranes heat sterilization: critical objects must undergo what type of cleaning semicritical: instruments that contact the mucous membranes but do not penetrate them high-level disinfectants: semicritical objects must undergo what type of cleaning noncritical: objects that do not come in contact with mucous membranes intermediate-level disinfectants: noncritical objects must undergo what type of cleaning lipophilic: viruses are enveloped by lipids; easier to kill hydrophilic: viruses are coated with a protein; harder to kill low-level disinfectants: detergents or cleaning agents spray, wipe, spray: application from bottled surface disinfectants procedure order

internal indicator strips: indicators placed inside the package/ cassette with instruments and indicator is visible from outside of packaging class 1: class of AMMI are external indicators in the form of tape or printed packaging that distinguish between a processed and an unprocessed item class 4: class of AMMI are multivariable indicators placed inside packaging and designed to react to two or more of the critical variables for sterilization class 5: class of AMMI are integrating indicators that measure all critical variables for sterilization and which are placed in the same type of packaging biological monitoring: use of bacterial spores or indicators to test the ability of the sterilization cycle to kill highly resistant microorganisms Geobacillus stearothermophilus and Bacillus subtilis: the 2 types of biological indicators (BIs) unit dose: packaging small amounts of material or supplies in individual packets for use on individual patients exposure control plan: step by step instructions regarding exposure incidents in each dental office ground fault circuit interrupter (GFI or GFCI): standards for electrical safety require that outlets near a sink incorporate a what ergonomics: area of science which assesses the human body and promotes the comfort and efficiency of a worker safety data sheet (SDS): a paper that lists the hazards of a certain material, precautions, and procedures regarding that material
