Safety & Sanitation TM 3 The Game Plan… O Review of Safety and Sanitation Hazards O Attack of the Germs! - Activity O Group Discussion O Exit Slip: Formative Assessment Questions Safety & Sanitation TM 4 Formative Assessment O Complete an Exit Slip O Evaluate the relationship between proper sanitation of clinical facilities and potential hazards to the medical staff. O Describe three steps that you can take to ensure your own safety when working with animals during class. Safety & Sanitation TM 5 Safety With Animals O What are some potential hazards a person may encounter when working with animals? Safety & Sanitation TM 6 Four Hazards in Veterinary Medicine O Chemical Hazards: - Ingestion or handling of hazardous medication or materials O Physical Hazards: - Bodily injuries from working with animals and medical equipment O Biological Hazards: - Contracted from handling medical wastes O Zoonotic Hazards: - Disease that are spread from animals to humans through viruses, bacteria, parasites, fungus Safety & Sanitation TM 7 Chemical Hazards O Chemical Hazards: - Ingestion or handling of hazardous medication or materials Drugs/Medication Cleaning agents Insecticides Anesthetic gases Many hazardous chemicals are routinely used in veterinary hospitals. Safety & Sanitation TM 8 Chemical Hazards O These chemicals can cause damage to the skin and eyes and to the lungs if they are inhaled. O Some chemicals may also cause abortion and/or fetal abnormalities if absorbed into the bloodstream. O Never use a substance for anything other than its intended use!!!! Safety & Sanitation TM 9 Physical Hazards O Physical Hazards: - Bodily injuries from working with animals and medical equipment Animal injuries – bites, kicking, scratches Back injuries – improperly lifting heavy objects or animals Falls on wet floors Exposure to x-rays Safety & Sanitation TM 10 Physical Hazards O Physical injuries from animals are the most common. O Physical hazards are especially dangerous when working with farm animals due to their size. O Cats needle-like teeth and sharp claws harbor bacteria that can cause serious illness in humans. Safety & Sanitation TM 11 Physical Hazards O To prevent injury proper clothing and footwear should always be worn when working with animals. O Learning animal behavior and the correct handling and restraint techniques can help prevent injuries. Safety & Sanitation TM 12 Biological hazards O Biological Hazards: - Contracted from handling medical wastes Living tissue and organisms Blood Urine Live vaccines Medical waste that has had contact with living tissue (urine soaked blankets, bandage material, etc.) Needles and scalpels “Sharps” Safety & Sanitation TM 13 Biological Hazards O The danger of biohazards is that they can spread disease from one animal to another or from animals to humans. O Medical wastes must be disposed of properly! O Gloves and protective clothing should be worn when handling biohazards. Safety & Sanitation TM 14 Zoonotic hazards • Zoonotic Hazards: - Disease that are spread from animals to humans through viruses, bacteria, parasites, fungus Viruses Rabies Sleeping Sickness (Encephalitis) Parasites Mange Toxoplasmosis Bacteria Cat Scratch Fever Salmonellosis Anthrax Tuberculosis Fungus Ringworm Safety & Sanitation TM 15 Zoonotic Hazards O There are several ways to prevent the spread of these diseases including: • Vaccination of animals and humans • Proper waste disposal • Isolating infected animals • Proper handling of infected animals • Proper sanitation of hospital • Hand washing • Wearing protective clothing Safety & Sanitation TM 16 Activity O Is it possible to come in contact with these hazards in vet science class? O How easily can you contract a harmful substance (such as medical waste or disease) from a surface or animal? O Do we usually clean effectively or quickly? Safety & Sanitation TM 17 Discussion O What protective measures can we take as a class to ensure the safety of ourselves and your classmates? Safety & Sanitation TM 18 Rules When Working With Animals 1. Always wear protective clothing and equipment, when necessary. (Gloves, Long Pants, boots, Mask) 2. Always wash clothing & equipment after use. 3. Wash hands & body between each patient. 4. Keep hands away from eyes and face. 5. Do not consume food or drink where contamination may occur. 6. Remove contaminated equipment. Coats, coveralls, etc. 7. Always label medications and chemicals properly. 8. Be trained properly on handling techniques. 9. Always keep first aid kit handy. 10. Be aware of surroundings. 19 Exit Slip O Describe the relationship between proper sanitation of clinical facilities and potential hazards to the medical staff. O Describe three steps that you can take to ensure your own safety when working with animals during class? Safety & Sanitation TM 20 Types of Sanitation O Cleaning –physically removing all visible signs of dirt and organic matter such as feces, blood, hair, etc. O Disinfecting –destroying most microorganisms on nonliving things by physical or chemical means. O Sterilizing – destroying all microorganisms and viruses on an object using chemicals and/or heat. O Antiseptics – solutions that destroy microorganisms or inhibit their growth on living tissue.
