The term that describes a material that can cause a choking hazard is asphyxiating agent. This classification typically refers to substances that can interfere with the body's ability to take in air or that can block the airways. Asphyxiants can be gases or particulate matter, and they pose serious risks in various environments, particularly in construction or industrial settings where inhalation of harmful substances is a concern.

Combustible materials, while they can pose fire hazards and result in smoke inhalation, primarily present risks associated with fire rather than choking. Toxic substances are harmful when ingested or absorbed but do not specifically refer to choking hazards. Corrosive materials refer to substances that can damage living tissue or destroy materials upon contact, but they do not inherently cause choking. Understanding the specific hazards associated with these categories is crucial for effective health and safety management in construction and other industries.
