What should a responder do if a chemical is highlighted in green on a HAZMAT reference?

When a chemical is highlighted in green on a HAZMAT reference, it indicates that there are specific inhalation hazards associated with that substance. Therefore, the appropriate action for a responder is to check for inhalation hazards and the necessary protective actions to take when dealing with the chemical. This is critical because inhalation of toxic substances can lead to serious health risks or even fatalities, making it essential for responders to understand how to protect themselves and others from inhalation exposure.

Properly assessing inhalation hazards informs responders of the necessary personal protective equipment (PPE) required and any recommended decontamination procedures. It also helps in planning evacuation routes or shelter-in-place actions if there is a risk of exposure to breathable toxic vapors.

Other options, while relevant to a HAZMAT situation, do not directly address the immediate concern of inhalation risks associated with a green-highlighted chemical. Storage procedures, fire risks, and environmental impacts are all important factors, but they are secondary to the immediate need for understanding inhalation hazards when encountering potentially dangerous chemicals.
