Maryland indoor moisture briefing Evidence note 25
Mold Planning After a Flood
Flood cleanup begins with safe entry and contaminated-water awareness, not cosmetic surface work.
Short answer
Start with evidence you can name
Flood cleanup can involve structural, electrical, chemical, sewage, slip, and exposure hazards in addition to mold. CDC and EPA disaster guidance puts safe entry, personal protection, water-damaged material removal, drying, and documentation ahead of cosmetic cleanup.
Safety boundary: If there is contaminated water, structural damage, an electrical hazard, unsafe access, suspected HVAC contamination, or a health concern, stop and use the appropriate qualified help. For this topic, first note people with asthma, lung disease, immune suppression, or other health concerns who should avoid cleanup.
