Quality Standards Comment

The standard European approach for disinfectant validation is divided up into three phases:

  • Phase 1: Basic Suspension Tests for fungicidal and bactericidal activity
  • Phase 2
    • Step 1: Suspension and surface tests to evaluate the activity of a disinfectant against a range of microorganisms under conditions which more closely simulate practical use.
    • Step 2: Surface test (= carrier test): surface samples are inoculated with a selection of microbial challenge organisms. A disinfectant is applied to the inoculated surfaces and exposed for a predetermined contact time.
  • Phase 3: Field Trial

Applicable standards for the antimicrobial activity

  • EN 1275: 2006: Chemical disinfectants and antiseptics - Quantitative suspension test for the evaluation of basic fungicidal or basic yeasticidal activity of chemical disinfectants and antiseptics - Test method and requirements (phase 1)
  • EN 1040: 2006 : Chemical disinfectants and antiseptics - Quantitative suspension test for the evaluation of bactericidal activity of chemical disinfectants and antiseptics – Test method and requirements (phase1)
  • EN 13727+A2: 2015: Chemical disinfectants and antiseptics - Quantitative suspension test for the evaluation of bactericidal activity in the medical area - Test method and requirements (phase 2, step 1)
  • EN 14561: 2006: Chemical disinfectants and antiseptics. Quantitative carrier test for the evaluation of bactericidal activity for instruments used in the medical area. Test method and requirements (phase 2, step 2)
  • EN 13624: 2013: Chemical disinfectants and antiseptics. Quantitative suspension test for the evaluation of fungicidal or yeasticidal activity in the medical area. Test method and requirements (phase 2, step 1)
  • EN14562: 2006: Chemical disinfectants and antiseptics. Quantitative carrier test for the evaluation of fungicidal or yeasticidal activity for instruments used in the medical area. Test method and requirements (phase 2, step 2)

Regulatory

The combined detergent / disinfectant for medical devices has a dual status: biocide (group I PT2) and medical device (Class IIb) and must comply with both regulations:

Instructions for use

Use disinfectants with care. Always read the label and product information before use. Preparation of cleaning and disinfection baths is done according to the IFU of the cleaning agent manufacturer. Water quality used for each step is as recommended per IFU (water hardness, pH, temperature).

For the selected product(s): the solution must be diluted at 0.5% to be ready for use: 25 ml = 1 stroke of dosing pump for 5 litres water (put the product in the water and not the other way around).

The solution should not be kept for more than 24h and renewed immediately if visibly contaminated: when it becomes blurred or with dirty things at the bottom of the bucket. The containers used for disinfection must be washed, rinsed and dried when the solution is changed.

Brushes, single-use cloth and other cleaning accessories are as recommended by the MD Manufacturer's IFU or equivalent brushes (usually soft nylon bristle brushes). Unless clearly specified in an MD IFU, metallic brushes are not used.

After disassembly according to the MD manufacturer IFU, if needed, steps are as follows:

  • The MD is completely immersed in the bath. Articulated MD are open to minimize obscured surface area. Bubbles trapped in cavities and channels are eliminated. MD remains immersed during cleaning. Cleaning operations are performed in a manner that limits production of aerosols or dispersion of potential contaminated chemicals or water.
  • Gross soil is removed. Accessible surfaces are cleaned with appropriate tools until visibly cleaned. MD's with articulations are moved (open and close at least 5 times). Channels are brushed. Brushing is always performed in the same direction from the less soiled to the most soiled end (at least 5 times). It must be checked that internal lumen and cavities are completely perfused and in contact with solution.
  • MD is rinsed after the contact time has elapsed (recommended contact time = 15 minutes, use a timer) with appropriate water quality: 10 s at least for all external surfaces and 10 s flush for each channel.
  • Dry the equipment with clean, lint-free cloth (to prevent dilution of the disinfectant of second bath)
  • Repeat the same steps in a second bath.
  • Visually inspect all equipment/devices once the cleaning process has been completed and prior to terminal disinfection/sterilization to ensure cleanliness and integrity of the equipment/device (e.g. cracks, defects, adhesive failures). Repeat the cleaning on any item that is not clean. Instruments with coagulation residues that cannot be removed even by intensive cleaning must be discarded, because their proper functioning and their required sterile condition can no longer be guaranteed.
  • Follow the manufacturer's guidelines for lubrication.
  • Do not reassemble equipment/device prior to disinfection/sterilization.

Precautions for Use

Always read the label and product information before use. Prepare use-solution according instructions. Pay attention to the quality of water needed.

Do not use for the skin disinfection.

Do not mix with other products.

If solutions are used for too long, there is a risk of corrosion due to contamination levels and to increased concentration of cleaning/disinfecting solution (because of evaporation), and the risk of insufficient disinfection due to accumulated contamination (loss of active agent/protein interference).

Hazardous product: Check the SDS (Safety Data Sheet) information supplied with the product as the information may differ according to the manufacturer!

Causes skin irritation and serious eye damage

Wear protective gloves/protective clothing/eye protection/face protection

In case of contact:

  • IF SWALLOWED: rinse mouth. Do NOT induce vomiting
  • IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing.
  • IF IN EYES: rinse cautiously with water for several minutes. If the victim wears contact lenses, remove them if possible. Keep rinsing

Storage

Check the instructions from the manufacture

  • Between 5 and 35ºC, in a dry and well ventilated place
