Which statement about inhalant agents used for euthanasia is true?

The statement highlighting that animals must be protected from contact with the liquid anesthetic is true because inhalant euthanasia agents can have serious health implications if animals come into contact with them in their liquid form. Liquid anesthetics can be irritating or harmful to the skin, eyes, and mucous membranes of animals. Therefore, it is essential to ensure that animals do not have exposure to any liquid anesthetic to prevent adverse effects and to ensure the humane treatment of the animals during the euthanasia process.

This safety measure aligns with best practices in veterinary medicine and animal research to minimize distress and potential harm. Protecting animals from direct contact with these agents is a critical component of ethical care and handling in research and clinical settings, reflecting a commitment to both animal welfare and safety standards.
