Whether you’re doing the job yourself or giving advice to others, it’s critical that Flood Recovery work is completed thoroughly and correctly. A professionally executed plan will;
It is strongly advised that technicians have completed training and/or are familiar with the IICRC S500:2021 Standard for Professional Water Damage Restoration.
BEWARE OF FLOODWATER!
Floodwater should never be treated as normal rain water. It is critically important to take extra precautions when cleaning up flood affected properties, to ensure that you don’t come into contact with contaminated water. When large volumes of water flood through an inhabited town, the water kills animals, collects rubbish and backs up sewer lines. The water that constitutes “flood water” commonly contains bio-hazards that can quickly make humans and animals very ill.
Flood Water is defined by three categories. Before embarking on a job the category of flood water must be know to ensure an applicable plan is created and executed.
Category 1 – water originating from a clean, sanitary source such as broken water supply pipe.
Category 2 – flood water containing significant contamination such as a washing machine leak.
Category 3 – water which contains pathogens and toxic substances including chemicals.
This includes sewage back-ups and flood water from storms, etc. Note that where flood water is left unattended or comes in contact with organics or chemicals, etc the category may elevate to the next level.
A well created and executed plan by a qualified professional will include as a minimum;
Biosan II, Thymox and Percide achieve their primary role of destroying pathogens with amazing efficiency (see respective product information sheets). Whilst they share a large overlap in application, each biocide has unique characteristics which enable the restoration technician to achieve reliable results, every time with enviable efficiency.
Flood disaster projects frequently require an initial wash down to remove organic loading, surface soiling and bulk mould growth. These wash downs require solutions with the muscle to remove gross soiling and a biocide for the protection of technicians from dangerous pathogens and to suppress pathogen count and mould growth.
See Mould Removal section in our Restoration Handbook for treatment of mould growth.
A complete kill of bacteria, viruses and mould is required for successful flood restoration and mould remediation. Thymox, Biosan II and Percide fulfil this function to perfection. Each has been tested to internationally recognised disinfectant micro-laboratory testing procedures under dirty conditions.
In most applications any of these products can be used, however a few points of note are;
Mould growth and organic soiling creates unsightly and stubborn staining. Percide has inherent ability to oxidise and remove the toughest of mould and organic staining. Percide can be further boosted with Percide Boost which dramatically enhances it’s destaining action. It is ideal for stain removal following an initial wash down.
Percide has several excellent benefits for this role;
See also the Actichem Odour Control / Elimotech section in our Restoration Handbook.
The key to odour neutralisation is to remove the odour source. The action of the Biosan II and Percide would normally achieve this during the flood restoration process. However, further odour control is often required to absorb air-borne and trapped mal-odour molecules and to provide a fresh replacement scent.
A note on surface types.
Thymox, Biosan, Percide, Deozyme and Deosan are safe for use on most water cleanable surfaces when used as directed. However please note the following points;
