1. Assess the scene
The first step is to understand the source, affected area, property type, and any materials that may have absorbed contamination.
2. Control the work area
Access may need to be limited while affected materials are evaluated and cleanup is performed.
3. Remove or remediate affected materials
Some materials can be cleaned. Others may require removal when contamination has penetrated porous or inaccessible areas.
4. Address remaining contamination and odor
Odor treatment should follow source remediation rather than substitute for it.
5. Review the treated area
The final step is to confirm that the planned scope has been completed and explain any remaining property-repair needs that fall outside cleanup.
Important: If there is immediate danger, an active crime scene, or a medical emergency, call 911. When law enforcement is involved, cleanup should begin only after the scene has been released.
