For bio-decontamination of trauma scenes, a comprehensive understanding of the principles of bio hazards and disinfection is essential.
As each job presents unique challenges, versatility and adaptability is key. The main focus is on on make-safe disinfection and final eradication of all pathogens. Other key areas to address are organic load removal/cleaning, odour control and stain removal.
It is strongly advised that technicians have completed training and/or are familiar with the IICRC S540 Standard for Trauma and Crime Scene Cleanup. This standard and the following guidelines assumes that all scenes have been released by law enforcement or regulatory agencies.
TGA listed (AUST L 332364), fifth generation quaternary ammonium compound based hospital grade disinfectant.
Biosan II has been specifically designed to overcome the challenges of bio-decontamination clean-ups including trauma, unattended death, sewage and flood waters. It is independently verified to effectively eradicate Bacteria, Viruses and Mould/Fungi.
• Dilute: 1:25 (50ml/1Lt)
TGA listed (AUST L 332284), potentiated hydrogen peroxide based hospital grade disinfectant, with a boosting option. (Testing is done without use of Percide Boost).
Percide has a ultra – high performance disinfectant/ bio-decontaminant with the advantage of blood, mould & organic stain removal. It is independently verified to effectively eradicate Bacteria, Viruses and Mould/Fungi.
• Ready to Use.
A powerful quad-bio enzyme blend which digests rank organics. Deozyme employs the innovative ElimoTech chemistry to permanently neutralise mal-odour molecules from bacteria, rotting organics and bio-contaminants.
• Dilute 1:16 (60ml/1Lt)
Equipment
The equipment required will vary from job to job. Below is a guide for some of the equipment you might need for decontamination of trauma scenes.
• Low Pressure Sprayer
• Cloths and Sponges
• Brush or Scourer Pad
• Wet vacuum
• PPE – On all jobs big and small, be sure to wear all the recommended personal protective equipment.
Ensure that you have read and understood the safety data sheet and technical information for all chemical products used, This includes a thorough understanding of directions for use and the limitations and capabilities of each product.
All methods and procedures should be according to the IICRC S540 Standard for Trauma and Crime Scene Cleanup. Including requirements for PPE, personnel safety, containment systems and documentation requirements.
Process
-
Initial Make Safe
- Apply the Biosan II solution to all affected areas. Ensure all areas and surfaces come into contact with the solution. Application is normally by means of a course spray.
- Allow a minimum of 10 minutes dwell time.
-
Wash Down
- Remove and clean away all the organic matter and debris, washing down with the Biosan II solution as you go.
-
Discolouration and Stain Removal
- Apply Percide to the affected area. Ensure all areas and surfaces come into contact with the solution. Application is best affected by means of spray, wet fog, mop or cloth.
- Agitate briefly, wherever possible, to promote contact and penetration into porous substrates. Thorough agitation will dramatically aid stain removal.
- Allow a minimum of 5-10 minutes dwell time for effective stain removal.
Rinse thoroughly with clean water. - Repeating this process may be required for heavily stained or mouldy conditions.
Note: For wet fogging application, add 20ml Percide Boost / Litre Percide.
-
Odour Neutralisation
- Apply the Deozyme solution to a workable area using a sprayer, sponge or scrubber machine. Do not allow solution to dry onto the surface.
- Agitate and allow 30 minutes dwell time. Keep moist with solution
- Rinse the surface thoroughly using clean water. A high pressure or wet extraction washing system, will provide effective results.
- Rinse thoroughly with clean water.
- A 1:100 (10ml/1lt) Deozyme solution can be left as residual on resilient surfaces for further odour removal and re-odourising activity.
Further Notes
-
Alternative product
Thymox can be used as an initial make safe and wash down solution. It is a TGA-listed Hospital Grade disinfectant with an exceptionally safe and surface-friendly profile.
-
Percide
Percide can be used for the entire wash down if desired. And is especially preferred if drug use or/and severe pathogen infection is encountered.
-
Substrate Compatibility Notes
Biosan II solution, Deozyme and Thymox are safe to use on all water cleanable surfaces.
Percide is mildly acidic and an oxidiser – it is safe to use on all resilient surfaces except it may discolour some acid sensitive surfaces such as concrete and natural stone. If used on fabrics and carpet, Percide must be diluted to 50% strength with water. Always pretest to check for surface chemical sensitivity
-
Product Hazard Profile Notes
Biosan II solution, Deozyme and Thymox are non-hazardous in use.
Percide is mildly acidic and an oxidiser – skin contact can cause irritation and eye contact can cause severe burns. Wear appropriate PPE including gloves and goggles. Refer to the sds for further information.
