What material is important to assess before cleaning up a hazardous spill?

Assessing the spilled material is essential before cleaning up a hazardous spill because understanding the characteristics of the substance involved directly informs how responders should handle the situation safely and effectively. Knowledge of the chemical's properties, such as toxicity, flammability, corrosiveness, and reactivity, is critical for determining the appropriate containment, cleanup methods, and personal protective equipment needed.

For example, if the spilled material is a highly toxic chemical, responders must take precautions to avoid exposure, while spills of flammable liquids might require specific techniques to manage ignition sources. Furthermore, different materials may have particular disposal requirements after cleanup, making it crucial to identify what has been spilled.

Recognizing the correct spilled material also aids in assessing potential risks to human health and the environment, which is a primary concern during hazmat incidents.
