Final answer:
In the Emergency Response Guidebook, materials with a toxic inhalation hazard are indicated in bold print. This is crucial for emergency responders and aligns with regulations by the United States Department of Transportation and EPA.
Step-by-step explanation:
In the blue and yellow sections of the Emergency Response Guidebook (ERG), materials with a toxic inhalation hazard (TIH) are indicated by being written in bold print. This helps to quickly and effectively identify such hazardous materials during an emergency situation. The National Fire Protection Agency (NFPA) 704 Hazard Identification System complements this by providing additional safety information about these substances, including flammability, reactivity, and other potential hazards.
Knowledge of how to properly identify these hazards through the ERG and NFPA system is critical for emergency responders and professionals who are involved in the handling and transport of hazardous materials. Both the United States Department of Transportation hazardous materials regulations and EPA's hazardous waste regulations apply to these materials, underscoring their significance in maintaining public health and safety.
