Clean up Upon inspection, it was discovered that the dirty patches on the vertical and horizontal surfaces were not moulded, but was due to the frequent overspray and misting of beer in the room, which then spread and rested on surfaces around the area and solidified. The technicians first removed all contents from the rooms and then used a portable extraction machine to pressure clean all horizontal and vertical surfaces. The water was then extracted. Using Aeris cleaning chemicals, the walls were microfibre-wiped to ensure all contaminants were removed. Lastly, the refrigerator coils were given a good clean with a special Aeris coil cleaning chemical.

Clean up The bins were moved out of the way, and the kitty litter initially put down to absorb some of the oil was collected and disposed of off-site. the technicians first poured a specialised degreasing cleaning solution to help break down the oil when scrubbed. After the concrete was scrubbed of oil, using the truck-mounted pressure cleaning extraction machine, the technicians applied further cleaning solutions with a pressure spray. Once done, the oil was pressure hosed towards an extraction wand that extracted the resulting liquid. This was repeated few times until the area was satisfactorily cleaned.

Process • Set up a pedestrian exclusion zone for the safety of the public and the workers • Covered outside furniture with plastic sheets to prevent cross-contamination from faecal matter being removed from above • Used Plastic sheeting to cover ground, to prevent further contamination to the pavement • Technicians used cleaning chemicals to soak faecal matter, once moist and softened, it was physically removed with microfibre cloths • Pressure cleaned metal trusses and surfaces with low psi • Removed liquid waste with a portable extractor • Antimicrobial treatment to the immediate area

Works Completed First stage Cleaning Installed Abatement HEPA air filtration units during the work process to “scrub” the air of harmful particles. All surfaces were given an initial clean with a T-bar, micro-fibre and mop to all surfaces to reduce the risk of infection to workers. Second Stage Cleaning Scrubbing and wiping with microfibre cloths all surfaces including walls, ceilings, floors, windows, tables, doors, frames, benches, glass pane toilets, etc. with antimicrobial treatment. Wipe down with dry clean microfibre cloth Third Stage Cleaning Third stage clean – Pressure clean/ scrub and treat walls, floors, toilets, shower/bathroom Immediately wipe dry wet surfaces Front Hallway/Corridor surfaces make safe clean and treat, concerns of staff for any cross-contamination Treatment clean, mop and dry floors

Sewage Gas Removal Afterwards, NLR helped oversee the deconstruction and removal of components of the gas trap and interceptor system. This involved decontamination cleaning rinse to the disassembled units before removal off-site. The technicians also used a pressure truck mount system to pressure clean any decontaminated areas due to spills. Environmental assessment Lastly, after a period of HEPA air scrubbing, to ensure the area was safe for further works, New Life Restoration used a photoionized detector and gas analyser, to determine the air quality of the area.

Cleaning Procedure Removed grease solids from the affected area Primary degreaser application to affected walls and concrete Set up negative pressure for ventilation of fumes from the area Truck mount pressure clean/extraction and to all affected areas Wipe/scrub down all affected areas Disposal of waste/grease trap oil debris off-site Clean down and degrease tools/equipment off-site Interested in Our Grease Trap Overflow Clean Up Service?

Flu Decontamination As part of the delivery of high-quality cleaning service to the school in this scenario, NLR had implemented the use of ATP bioluminescence testing to monitor standards of cleaning. In accordance with Guidelines for Cleaning Methodologies, Applications and Equipment 2014, key cleaning principles were followed including – but not limited to – adequately trained cleaning staff, wearing suitable PPE, use of laundered, hygienic cleaning equipment such as re-usable microfibre cloths and mops, HEPA filter vacuum cleaners and appropriate TGA approved detergent/disinfectant cleaning solution in required concentrations. In order to scientifically measure the cleanliness of surfaces ATP testing was conducted before and after the cleaning process. ATP (adenosine triphosphate) is present in all living cells and can be used as an indicator of biological contamination on surfaces.
