NONCHEMICAL methods used to reduce contamination in animals drinking water
Reverse osmosis and UV radiation
How are fume hoods different from biological safety cabinets?
Workstation that protects the user from chemical fumes. It does not protect the animal from any pathogens that might be in the room air. Are only used for chemical fumes and NOT for biohazardous or infectious agents.

What are biological safety cabinets used for?
Animal facilities that use infects agents must have BSC’s to protect personnel from exposure to harmful microorganisms.
How do BSC’s work?
A fan in the cabinet draws air in from the room into the opening and thru the ducts which have HEPA filters, and is then exhausted outside.
Describe class I BSC’s
Used for equipment that generate dust or aerosols like changing small animal cages. They draw in UNFILTERED room air. This means they protect the user but not the animal within the cabinet.
Describe Class II BSC’s
Draws air from the room and HEPA filters it, circulates and is HEPA filtered again before it is exhausted. Protects animal inside from contaminants in room air? This class has different types of cabinets depending on the percentage of air that is recirculated and exhausted.
Describe Class III BSC’s
Aka glove boxes. Airtight cabinets that are used with high risk biological agents. Personnel do not come into contact with materials inside the cabinet because long heavy rubber gloves are attached to the gas tight ports.
