Answer: (A)

Gases poisonous by inhalation are categorized as toxic inhalation hazards within the gas class. This division is dedicated to gases that can cause death or serious harm when inhaled, even if they aren’t flammable. Recognizing this helps you understand labeling and required protective measures—look for the Poison Inhalation Hazard indication and plan appropriate respiratory protection and ventilation. It’s distinct from other gas-related hazards, such as flammable gases, which fall under a different part of the gas class. So, the gases that are harmful or lethal to inhale are placed in the division that handles toxic inhalation hazards within the gas category.
