Emergency disinfections suit high-consequence turnovers: flood slime, tenancy handovers tied to contagion timelines, sewage intrusion—not everyday wipe-down cadence alone.

Three response pillars

• Quick response crews shorten cross-touch pathways while occupants stage elsewhere safely.
• Effective disinfection honours label dwell volumes and ACH before re-entry.
• Peace of mind follows documented checkpoints rather than improvised mixing of cleaners.

Hazards to avoid DIY

Unsupervised ammonia–chlorine combos, improvised misting rigs without MSDS buffers, ozone saturation without electronics clearance—defer to indemnified outfits publishing SOP breadth.
