What are "Toxic Inhalation Hazards" (TIH)?

Toxic Inhalation Hazards (TIH) are defined as chemicals that can pose a significant risk to health when they are inhaled. This category of substances includes gases, vapors, or particulates that can lead to immediate health effects or long-term health risks. The focus on inhalation is critical because many harmful chemicals can affect respiratory systems, potentially leading to severe health outcomes quickly compared to other exposure routes such as skin contact or ingestion.

For example, substances like chlorine or ammonia fall into this category and can cause serious respiratory issues upon exposure. Awareness of TIHs is crucial in hazmat operations, as first responders must be prepared to identify and mitigate these hazards effectively to protect both their own safety and that of the public.
