What is a critical step that must be taken before starting a hazardous waste operation?

Conducting a thorough site assessment is essential before commencing any hazardous waste operation because it allows for the identification of potential hazards present at the site. This assessment includes evaluating the physical, chemical, and environmental characteristics of the site, which is crucial for planning the operation safely and effectively. Understanding site conditions helps in the development of risk management strategies and informs the appropriate personal protective equipment (PPE) and emergency response procedures that need to be in place.

While obtaining necessary permits, training personnel, and establishing a waste disposal plan are also important components of hazardous waste operations, they are contingent upon the insights gained from a comprehensive site assessment. Without this foundational understanding, implementing any operation could overlook critical safety measures and lead to inadequate preparation for hazards that might be present.
