ALAT Occupational Health and Safety Questions and Answers 1 — Questions and Answers
Question 1: An ALAT is tasked with cleaning up a small spill of a hazardous chemical in the procedure room. According to standard safety protocols, what is the MOST important initial step?
- Wipe up the spill immediately with paper towels.
- Notify the facility manager by email.
- Consult the Safety Data Sheet (SDS) for the chemical. (Correct answer)
- Evacuate the room and close the door.
Correct answer: Consult the Safety Data Sheet (SDS) for the chemical.
Consulting the Safety Data Sheet (SDS) is the most critical first step. The SDS provides specific information about the chemical's hazards, required personal protective equipment (PPE), and proper spill cleanup procedures, ensuring the technician can respond safely and effectively.
Question 2: Which of the following is considered a primary ergonomic hazard for an Assistant Laboratory Animal Technician?
- Exposure to animal dander and allergens.
- A needlestick injury from an injection.
- Receiving a bite from an agitated animal.
- Repetitive lifting and moving of heavy cage racks. (Correct answer)
Correct answer: Repetitive lifting and moving of heavy cage racks.
Ergonomics deals with the study of people's efficiency in their working environment. Repetitive lifting, pushing heavy cage racks, and awkward postures are major ergonomic risk factors that can lead to musculoskeletal disorders (MSDs) in animal care staff.
Question 3: A zoonotic disease is a disease that is:
- only found in animals housed within a zoo.
- transmitted from animals to humans. (Correct answer)
- fatal to all animal species it infects.
- caused by poor sanitation in the facility.
Correct answer: transmitted from animals to humans.
Zoonotic diseases are defined as infectious diseases that can be naturally transmitted between animals and humans. Laboratory animal technicians must be aware of potential zoonoses for the species they work with to protect their own health.
Question 4: When working with rodents in open-top caging or during cage changing procedures, what type of Personal Protective Equipment (PPE) is specifically recommended to minimize exposure to allergens?
- A standard surgical mask
- A fluid-resistant gown
- An N95 respirator or PAPR (Correct answer)
- Safety glasses with side shields
Correct answer: An N95 respirator or PAPR
An N95 respirator or a Powered Air-Purifying Respirator (PAPR) is designed to filter out airborne particles, including the animal dander and proteins in urine that are major sources of allergens. A standard surgical mask does not provide adequate protection against inhaling these small allergen particles.
Question 5: An ALAT is administering an injection to a rabbit and accidentally sustains a needlestick injury. What is the correct immediate action to take?
- Finish the procedure before seeking treatment.
- Immediately apply a pressure bandage to the wound.
- Wash the wound thoroughly with soap and water. (Correct answer)
- Report the injury only if it appears infected later.
Correct answer: Wash the wound thoroughly with soap and water.
The first and most important step after a sharps injury is to immediately and thoroughly wash the wound with soap and water for several minutes to help remove any potential contaminants. After washing, the injury must be reported to a supervisor to ensure proper follow-up medical care and documentation.
Question 6: According to safe sharps handling practices in a laboratory animal facility, what is the proper procedure for disposing of a used needle and syringe?
- Recap the needle using two hands before placing it in the trash.
- Place the uncapped needle and syringe directly into a designated sharps container. (Correct answer)
- Bend or break the needle to prevent reuse before disposal.
- Leave the syringe on the counter for a designated person to collect later.
Correct answer: Place the uncapped needle and syringe directly into a designated sharps container.
To prevent accidental needlesticks, used needles should never be recapped (unless using a one-handed scoop technique is required by the procedure), bent, or broken. They should be immediately placed into a designated, puncture-proof sharps container after use.
