If a hazardous substance spills, what is the first step you should take?

When a hazardous substance spills, the first critical step is to read the Material Safety Data Sheet (MSDS), now commonly referred to as the Safety Data Sheet (SDS), for the substance involved. The SDS provides essential information about the chemical, including its properties, hazards, and recommended emergency procedures. By consulting the SDS, you gain insight into the necessary precautions, suitable personal protective equipment, and specific actions to take in the event of a spill.

This step is vital because the recommended procedures can vary significantly depending on the type of hazardous substance. For instance, some substances may require containment rather than dilution or might necessitate specialized handling techniques to mitigate risks. By referring to the SDS first, you can ensure you are following the correct protocols to manage the spill safely and effectively.
