affective cleaning reducing exposure testing training facilities and equipment
what should cleaning records contain
type of cleaning
when cleaning was performed
who performed the cleaning
type of cleaning material used
what factors should be considered when selecting a decontamination method
microorganisms involved
level of decontamination required
