Decontamination
The Decontamination service safely removes hygiene risks such as rodent activity, spoiled food or chemical spills. Our trained technicians work with care to eliminate the threat without creating cross-contamination, restoring hygiene critical environments back to compliance.
What is Decontamination?
Decontamination involves the safe removal, containment and sanitising of areas affected by hygiene risks such as rodent activity, spoiled food, nesting materials, chemical spills or high-risk residues. Our trained hygiene technicians follow strict protocols to prevent cross-contamination and restore work environments back to safe, compliant conditions.
