Deep Cleaning and Fogging Services
What is a deep clean?
Media attention throughout 2020, using the term deep cleaning in a variety of ways, has led to a degree of confusion about the term “deep clean”. A classic deep clean uses a variety of steps and materials, to effect both a thorough physical cleanliness of surfaces, with special attention to disinfection of high touch or “risk” surfaces, all with appropriate, professional grade cleaning chemicals and PPE.
The basic methods vary slightly between laboratory settings, medical environments, teaching settings and commercial environments. However, the overall steps remain the same.
Assessment, HEPA vacuum, clean/disinfect and test
Professional assessment of the reason that a deep clean is needed is a crucial first step. This allows the refinement of cleaning methods, appropriate chemical selection and application methods. Once the approaches and appropriate safety documentation is in place, a general HEPA vacuum step is used to safely remove potentially contaminated particulates. Physical cleaning of surfaces proceeds next, to allow a clean enough surface that disinfectants can be applied to – so that they are effective. The appropriate disinfectants, at the right concentrations, are applied, and left to the contact time required to do their work. Finally, a site specific testing process is conducted to verify the effectiveness of the cleaning.
Our staff are well trained and experienced in the appropriate requirements for your facility type and responsibly dispose of waste materials post deep clean.
Disinfection Fogging Services
Fogging of disinfectant solutions is a useful tool in decontamination methods. In general, it is not a substitute for physical cleaning or gaseous disinfection methods, rather, a very useful, cost effective method for solving specific pathogen contamination.
No matter how comprehensive the routine physical cleaning and disinfection regime is, it is extremely difficult to completely eliminate microbial cross contamination from hard-to-reach surfaces and air which may cause product/process spoilage, infection or safety issues. At times, micro-organisms can persist in facilities for years – despite regular routing, general cleaning.
In addition to physical cleaning methods, a facility can be fogged to provide whole room decontamination. This rapid method of disinfectant delivery also minimises the need to use ladders to disinfect elevated furniture and equipment.
Ultra-Low Volume (ULV) or Electrostatic (ES) foggers and can achieve high levels of airborne and surface decontamination - up to 6 log reductions in some cases; more commonly, 4 log reductions are achieved. Effective decontamination is possible for a wide range of bacteria, viruses, fungi and spores. Careful selection of the appropriate disinfectant is essential; Chlorine Dioxide, Hydrogen Peroxide or F10TM* are commonly selected. Often, the chemical used is determined by regulators or governmental standards.
Biosafety is able to assist you in choosing if fogging is the right method for your site and guide you to the correct, approved chemical for your site, then have our approved staff conduct the disinfection process.
