Clinical Flashcards
Agency for developing precaution protocols for employees, in compliance with blood-borne pathogen standard
OSHA
Agency recommends infection control protocol and researches how diseases are transmitted
CDC
Sharps, blood, saliva
Biohazard
Agent: Corrosive to metal, strong odor
Chlorine based compound
Kills MOST pathogenic microbes, not spores. Broad spectrum.
Disinfection
Agent: can discolor surfaces yellow
Iodophors
Agent: may leave a film or residue on surfaces
Phenols
Agent: not corrosive, lower kill spectrum
Quaternary Compounds
Agent: should not be used as surface disinfectant. Toxic effects from fumes. Corrosive.
Glutaraldehydes
Kills ALL pathogenic microbes including spores
