Should responders consider multiple hazards regardless of labeling or placarding of substances?

Responders should always consider multiple hazards, regardless of the labeling or placarding of substances, because labels and placards may not provide a complete picture of the potential risks associated with a material. While these indicators offer important information, they cannot capture all possible hazards, especially in situations where materials may interact with each other or when additional hazards are present, such as environmental factors or hidden dangers.

For example, a substance might be correctly labeled as a flammable liquid, but that label alone does not account for potential toxicity or corrosiveness. Responders may encounter scenarios where substances are misidentified or where new hazards are presented due to the specific conditions of the incident. Therefore, considering multiple hazards ensures that responders can adequately assess the situation, protect themselves, and respond effectively.

This approach aligns with best practices in hazmat response, emphasizing the need for a comprehensive situational awareness that goes beyond the visible indicators provided on labels and placards.
