2. Cage washers Clean animal caging Dedicated space
Connect “dirty” and “Clean” areas of cage storage
Programmable cycles
180 final rinse

3. Cage washers Use high temps and harsh chemicals
Safety features – inside door release, door closure latches, windows in the doors
Note any malfunctions – notify supervisor
Tunnel washers – small equipment
Rack washers – large equipment
Cabinet washers – small eqipment

4. Cagewashing Equipment
automatic
cabinet
washing, rinsing drying cycles
rack
entire rack can be moved into washer
dirty side to clean side
tunnel washers
has conveyor belt to move items through washer
must visually inspect after cleaning

5. Tunnel washer

6. Other cage washing system
Pressure washers
Misters and foggers – spray disinfectant as a fine mist.
Foamers – connected to the room hose

7. Automatic waterers eliminate work of water bottles
water pressure appropriate for species
treated, filtered water
Chlorine UV RO
Filtered to reduce particulates – can clog system

8. Watering systems Lixits MUST be checked regularly
young animals or newly received animals may have to be given water bottles until they adjust to the lixits
not drinking will cause not eating
Clogged lixit can flood solid bottom caging

9. Feeding and Watering Accessories

10. Change stations or Laminar Flow cabinets
Used for cage changing
Use High-efficiency particulate air (HEPA) filter
Blown from back, around cabinet, into front grate
Not to be used with hazardous agents, anesthetic agents, or caustic chemicals

11. Cage dumping station Used to empty dirty bedding into
Reduces dust and allergens
Pulls particles away from technician

12. Fume Hoods Protects user from chemical fumes
Draws fumes away and out of the buildding
Only for chemical fumes not biohazard

13. Biological Safety Cabinet
Designed for work with infectious diseases
HEPA filters and Pre-filters
Class 1 – used to enclose equipment

14. BSCs Class 2 – recirculates filtered air, several different types
Class 3 – “glove boxes”- airtight – personnel do not come into contact with infectious agents

15. Autoclaves Used to sterilize equipment – aseptic surgical procedures
Decontaiminate
Time and temp determined by material
Never autoclave flammable liquids or radioactive materials
Variety of sizes

16. Vacuums
Must have HEPA filters
Wet and dry
Clean hoods

17. Tissue digesters Large pressure cookers
Combination of caustic chemicals, water, and heat
Breaks down tissues

18. incinerators Large ovens that burn tissues Kills infectious agents
Outside or needs chimney
Ash disposed of in trash

19. Measuring Devices body weights and/or food
accuracy- refers to the degree that the weight measured is the actual weight.
Top-loading balances are most common

20. Other types triple beam double pan platform scales
“tare” zero weight (eliminates weight of restrainer)

21. clean scales after use prevent disease transmission
keep scale in good condition
