Why is Safety Important?Why is Safety Important?• Many potential hazards in
Veterinary Medicine–Anesthesia–Radiology–Zoonosis–Chemicals–Physical Hazards–Animals–Sharp objects –Heavy lifting
Specific Hazards in Clinical Specific Hazards in Clinical Pathology include:Pathology include:
•1. Physical Hazards•2. Electrical Hazards•3. Chemical Hazards•4. Biological Hazards
SafetySafety
• You need to make sure that:•The veterinarian is safe•The technicians/veterinary assistants are safe
•The owner is safe•The animal is safe•Everyone is kept safe
Physical Physical HazardsHazards
Physical DangersPhysical Dangers•Animal handling
– Animals are unpredictable– Anticipate bites and scratches
•Don’t put yourself in a position to be bitten.
– Use your safety equipment•Muzzles – for cats and dogs•Leashes – or towels to pick up•Gloves – for raptors & exotics•Bondage – cat bag or tape for feet
Muzzle!Muzzle!
Heavy LiftingHeavy Lifting
• Animal can be heavy!– Lift only up to 40 pounds alone– Lift only what you are capable of
lifting– Use the buddy lift often– Always lift with the power of
your legs, not your back– Back injury does not go away!!!
Electrical Electrical HazardsHazards
ElectricalElectrical• Could shock you or your patient
– Ground all equipment thoroughly– Disconnect electrical equipment
before repairs or replacement of bulbs and other items
– Check for exposed wires & have them fixed before use
– Keep cords away from birds, rabbits and young chewy critters
FireFire
• Can burn you and/or others– Know where to find blankets, fire
extinguishers & other equipment– Have a fire plan for escape– Find out what the policy is for
animals?– Use care with Bunsen burners,
open flames, dryers, autoclaves & other potential fire hazards
Potential Fire HazardsPotential Fire Hazards
Moving PartsMoving Parts• Use care when handling
equipment with moving parts– Centrifuge
•Never open it until it has fully stopped moving
•Use only if you have been trained•Must be balanced when running•Must be operated with the lid latched•Must be cleaned immediately if
anything is spilled or broken
Moving PartsMoving Parts•Dryer
– Never reach in until it has fully stopped
– Check the lint trap regularly
Chemical Chemical HazardsHazards
Chemical HazardsChemical Hazards
• Chemicals may cause burns– Careful when working with strong
acids & bases – wear protective gear– Careful not to splash chemicals– Wash off immediately any you do
get on your skin or in your eyes•Know where the eye station is
– Label all chemicals properly according to OSHA standards•OSHA = Occupational safety and
hazards association
ChemicalChemical• May be poisonous
– Toxic fumes •always use a fume hood
– Never put things in your mouth•Needle capping•Pipettes
• May be carcinogenic– Double gloving & special safety
equipment may be used
Biological Biological HazardsHazards
BiologicalBiological
•Zoonosis– Disease that is communicable from
animal to man– We can get it from animals and we
can pass it to other animals•Handle all specimens carefully•Gloves should be used if you have any
open wounds or cuts on hands•No eating or drinking in the work area
ZoonosisZoonosis• Toxoplasmosis
– Protozoan parasite causes damage to unborn fetus
• Other Parasites– VLM, CLM, Mites, Ringworm, etc.
• Rabies– Deadly disease of warm-blooded
mammals• Cat Scratch Fever
– bacterial, cat is not sick - anaerobic infection from bacteria under their nails
Other Hazardous Other Hazardous SubstancesSubstances
• DMSO– DIMETHYL SULFOXIDE
• Formaldehyde• MLV Vaccines
– Modified live vaccines• Euthanasia solution
MSDSMSDS• All potential hazardous chemical that
you come into contact with in your working environment will have an MSDS. (Material Safety Data Sheet)
• The MSDS will list information on that chemical including:
–Hazardous ingredient information–Physical/chemical characteristics–Fire/explosive data–Precautions–Control measures –and much more
MSDSMSDS
• Know where you clinic or hospital keeps their MSDS
• Kept in a binder in a place accessible to all - Pharmacy
• Know where to find information on the chemicals you work with
Waste ManagementWaste Management
• An ongoing problem in Vet. Med.• Any item used to diagnose, treat,
or vaccinate an animal becomes waste
• Each type of waste is disposed of in a specific fashion regulated by OSHA– Occupational Safety and Hazard Ass.
4 Categories of Waste4 Categories of Waste
• Medical Waste• Biohazardous Sharps• Biohazardous Non-Sharp• Hazardous
– We will not have contact with hazardous waste
Medical Solid WasteMedical Solid Waste• Items that do not contain bodily
secretions– Non bloody/dried blood gauze or
bandage material– Gloves, no blood or contaminants– Soiled cage newspapers– Feces, Urine
• May be disposed of with regular trash, then into a locked dumpster prior to pickup
Biohazardous WasteBiohazardous Waste
• Any lab waste that may pose a threat to health – Blood, tissue, cultures etc.– Blood soaked gauze– Bloody or infected bandages– Dead tissue/body parts
• If not sharp, disposed of in red biohazardous bags
Sharps WasteSharps Waste• Any item used in the Dx, Tx, or
Immunization that has a sharp edge that may puncture skin– Slides/coverslips– Needles and syringes– Glassware used in testing– Scalpel Blades
• Must be disposed of in a puncture proof, rigid “Sharps” container
Hazardous WasteHazardous Waste• Poses a significant threat to
human safety – chemotherapeutic agents– Pesticides– pharmaceutical products
• Each item should be disposed of using a specific rigid protocol.
• We don’t usually come in contact with these.
Sharp’s ContainersSharp’s Containers• Must be labeled with:
– Hospital name– Address– Phone number– Date circulated
•Do not fill higher than fill line or ¾ full
• May be kept for 6 months or ¾ full – then disposed properly
Biohazardous BagsBiohazardous Bags• Must be labeled with:
– Hospital name– Address– Phone number– Date circulated
• May be kept for 6 months or ¾ full – then disposed properly
• Both Bio Bags and Sharp’s must be sealed & sterilized when full
DisposalDisposal• Pay a licensed biomedical waste
pickup firm to process your waste– many clinics do this
• Hauler agreement and receipts must be kept
• Autoclave the waste yourself and put it into your locked dumpster for disposal
• Records of autoclave maintenance & quality control, as well as waste weight amounts must be kept
Use the Common Sense Use the Common Sense ApproachApproach
• Wash your hands often• Clean up spills immediately• Close cupboards and drawers
when not in use• All ways keep cages clean• Avoid lifting heavy objects• Avoid bites & scratches
Use the Common Sense Use the Common Sense ApproachApproach
• Use your safety devices• If unsure, ask• Be careful with cords and
electricity or open flame• Pass sharp instruments handle
first – scalpels, needles• Keep hair back, jewelry to a
minimum
Use the Common Sense Use the Common Sense ApproachApproach
•Dispose of biohazardous items correctly– Biohazardos bags– Sharps containers
• If injured inform an Instructor immediately!
•Use common sense!!!

Review QuestionsReview Questions
• Why do we need to know about safety in the field we choose to work in??
• Because we need to insure that we, and anyone around us is not injured due to our ignorance.
Review QuestionsReview Questions
• Name three hazards in the workplace and how to avoid them.
• Fire – No open flames– Inspect all cords – Ground properly
Review QuestionsReview Questions
• What is biohazardous waste and what do we do with it??
• Biohazardous waste is any lab waste that may pose a threat to our health – Disposed of in red biohazardous
bags or “sharps” containers
Review QuestionsReview Questions
• Explain what using “common sense” means, and give some examples of using it.
• Common sense means we think before we act.– Washing our hands often– Using safety equipment – Asking for help if needed
