✔✔What are the 3 factors that should be considered when choosing an anti-microbial? -
✔✔type & extent of contamination, limitations, associated hazards
✔✔6 limitations of antimicrobial biocides -✔✔concentration, temperature, pH, dwell
time, application requirements, material compatability
✔✔What are 3 types of antimicrobial biocides? -✔✔sanitizers, disinfectants, sterilants

registration and labels for chemical
disinfectants. Fifra was passed in 1947 and
required all pesticides to be registered.
✔✔What is the concern of mixing bleach with ammonia? -✔✔bleach is very reactive &
will release toxic gases when mixed with ammonia
