CET Safety and Health Protocols 3 — Questions and Answers
Question 1: Which ventilation requirement is most critical when using carbon monoxide (CO) as a secondary euthanasia method?
- Heating and cooling the room to 68–72°F
- Maintaining CO concentration below OSHA's permissible exposure limit of 50 ppm in the work area (Correct answer)
- Using ultraviolet lights to neutralize CO
- Ensuring CO levels exceed 6% in the chamber only
Correct answer: Maintaining CO concentration below OSHA's permissible exposure limit of 50 ppm in the work area
OSHA's PEL for CO is 50 ppm as an 8-hour TWA; ventilation systems must prevent worker exposure from exceeding this limit.
Question 2: The Safety Data Sheet (SDS) for sodium pentobarbital must be accessible to euthanasia staff:
- Only upon written request submitted 24 hours in advance
- At all times during each work shift (Correct answer)
- Once per year during annual training
- Only when a spill occurs
Correct answer: At all times during each work shift
OSHA's HazCom Standard requires that SDS documents be readily accessible to employees during their work shifts.
Question 3: Compassion fatigue in euthanasia technicians is best addressed through which organizational safety measure?
- Increasing the number of animals euthanized per shift to minimize repeated exposure
- Providing regular access to mental health resources, peer support, and rotation of duties (Correct answer)
- Restricting technicians from discussing euthanasia procedures
- Eliminating documentation requirements to reduce administrative burden
Correct answer: Providing regular access to mental health resources, peer support, and rotation of duties
Structured mental health support, peer programs, and duty rotation are evidence-based strategies to mitigate compassion fatigue in animal care workers.
Question 4: Which of the following represents the correct order for donning (putting on) PPE before a euthanasia procedure?
- Gloves → gown → mask/respirator → eye protection
- Gown → mask/respirator → eye protection → gloves (Correct answer)
- Eye protection → gloves → gown → mask/respirator
- Mask/respirator → gloves → gown → eye protection
Correct answer: Gown → mask/respirator → eye protection → gloves
The correct donning sequence is gown first, then respiratory protection, then eye/face protection, and finally gloves to maintain barrier integrity.
Question 5: A euthanasia technician notices a crack in a CO chamber seal. The correct response is to:
- Continue use at reduced capacity until the next scheduled maintenance
- Immediately take the chamber out of service and tag it until repaired (Correct answer)
- Seal the crack with duct tape as a temporary fix
- Increase room ventilation and continue normal operations
Correct answer: Immediately take the chamber out of service and tag it until repaired
Any breach in a CO chamber compromises worker safety and must result in immediate removal from service until properly repaired.
Question 6: Under the DEA's regulations, how long must records of Schedule II controlled substance usage (including euthanasia agents) be retained?
- 1 year
- 2 years (Correct answer)
- 5 years
- Permanently
Correct answer: 2 years
DEA regulations require that Schedule II controlled substance records be maintained for a minimum of 2 years and be available for inspection.
Question 7: When zoonotic disease exposure is suspected after a euthanasia procedure, which agency provides guidance on post-exposure prophylaxis protocols?
- USDA Animal and Plant Health Inspection Service (APHIS)
- Centers for Disease Control and Prevention (CDC) (Correct answer)
- Environmental Protection Agency (EPA)
- Drug Enforcement Administration (DEA)
Correct answer: Centers for Disease Control and Prevention (CDC)
The CDC provides guidelines on post-exposure prophylaxis for zoonotic diseases such as rabies, which is directly relevant to animal euthanasia work.
