Personal Protective Equipment (PPE) Reprocessing Tests

The COVID-19 outbreak has caused a lack of PPE (Personal Protective Equipment); As a result, there are few options left in hospitals and healthcare facilities, one of these options; reusing equipment that will never be reused.

EUROLABhas prepared a testing plan to assist innovators trying to validate reprocessing solutions:

Disinfection / Sterilization

Respirators or masks undergo a disinfection or sterilization process to remove the virus and other potential contaminants:

• Evaporated hydrogen peroxide (VHP)  Masks are subjected to a specific cycle in a VHP sterilizer (VPRO 1 VPRO 60)
• Heat  dry-heat disinfection (70 ° -100 ° C)
• UV light at a certain intensity and time to ultraviolet light exposure (254-260nm)
• Chemical  spray disinfectants (soaking or wiping that could damage the liquid, etc.)
• Radiation  exposure to gamma radiation

Functionality Filtering / Breathability Test

Following the disinfection / sterilization reprocessing cycle, it is necessary to reassess the functional properties of the filter media:

• Respirators:  NaCl, DOP, valve leak and inhalation / exhalation tests
• Surgical Masks:  Synthetic Blood, BFE, PFE, breathability, Flammability

Biosafety Test

Following the disinfection / sterilization reprocessing cycle, it is necessary to reassess biosafety for the user:

• cytotoxicity  MEM Elution or Agar Plating
• Toxicological Risk Assessment

- or -

• cytotoxicity  MEM or Agar Overlay
• Irritation  In vivo contact dermatitis
• Sensitivity  In vivo hypersensitivity

EUROLAB, with its highly expert team and internationally accredited laboratories, Personal Protective Equipment (PPE) Reprocessing Tests It performs all test, analysis, measurement, evaluation and report generation services completely and reliably.
