Safe cleanup starts with isolating the source and stopping the leak if possible, then securing the area to prevent ignition and exposure. Spill containment uses booms, absorbent pads, and temporary berms to keep oil from drains and waterways. Responders wear appropriate PPE and follow site emergency procedures. Recovered oil and contaminated absorbents are collected for disposal or treatment under applicable regulations. Soil or water impacted areas may require excavation, skimming, or specialist remediation. Documentation and reporting are often required for environmental compliance.
