UV Surface Disinfection

Non-clinical disinfection is no less than a 1-Log or 90% or X10-fold microbial reduction, however, in the infection prevention and control arena, we recommend destroying pathogens to a disinfection level of no less than 3-Log or 99.9% or x1,000 fold reduction in most settings (depending on environment, microbe and application one is targeting).

Sterilization is a 6-Log reduction is a 99.9999% or x 1,000,000-fold reduction in microbes. All of PP-L Biosafety’s devices are capable of delivering a significantly superior microbial sterilization level than even this, 1 parts per million level.

Now let’s take today’s big concern – Coronavirus. Studies have shown that COVID-19 is primarily spread through respiratory droplets, some of which can settle on surfaces and spread to people after being touched or handled. On surfaces such as cardboard, the virus can survive for up to 24 hours, and it can survive for 72 hours on metal and plastics. This hazard can be eliminated and controlled with our germicidal UV-C devices.

Whether on goods, packaging, returned goods, tools, surgical/medical instruments and indeed, any surfaces, such as furnishings – germicidal UV disinfection will minimize the risk from ALL PATHOGEN infections, Covid-19 included, because surfaces can be quickly disinfected or sterilised using UV-C systems, which can be applied directly to individual surfaces and to all exposed surfaces within unoccupied environments.

Also known as UV-C, GUV or UVGI, short wavelength ultraviolet light disinfects, indeed, sterilizes all known pathogens and studies show it is “highly effective” against COVID-19 and all common pathogens, whether on organic or inorganic surfaces.

UV Surface Disinfection

Our UV-C surface disinfection will destroy all bacteria and viruses on surfaces including:

UV-C Surface Disinfection – high risk environments

Surface disinfection can be an effective step for pre-cleaning and/or post-cleaning of items and environments to reduce the risk of viral transmission through handling items or packaging. Pre-cleaning or post-cleaning with UV-C surface disinfection can be particularly beneficial for high risk environments such as:

For environments which are regularly unoccupied between uses, whole-room UV-C surface disinfection systems can provide fast and effective intervention between visitors or occupants.

Residue and chemical-free germicidal UV-C light ensures the highest level of hygiene standards. Our team of chartered engineers, scientists and medics specify and safely deploy some of the world’s most potent UV-C devices to destroy harmful microbes and reduce COVID-19 infection risk. Our team will advise minimum exposure times for surfaces, accounting for the beam angle, shine coverage/shadowing reduction, relative distance, humidity, temperature and any other relevant environmental factors.

We are here to advise you through the whole process of disinfection using UV-C integrated into your operations from risk assessment, modelling, design, supply and installation.

Disinfection Cabinets & Manufacturing Process-Lines

Our bespoke UV-C disinfection/sterilisation cabinets can be made to suit any instruments, equipment, organic or inorganic product, returned goods whether in a static environment or through a process line or conveyor.

The principle is the same as those UV-C cabinets that sterilise medical instruments against deadly microbes such as MRSA, C-Diff and the hospital “superbugs”. These systems can be created to the size and scale to suit your specific requirements, using powerful UV-C direct emitter units for rapid disinfection or sterilisation. These systems are specified built-in fail-safes to protect from accidental human exposure to mitigate such potential risks e.g. electronic timer, trip-switch, movement sensors, noise sensors and electrical interlock.

Our surface disinfection systems are widely used in food processing – vegetables, fruit, diary and meat to prevent pathogenic harm to the workforce or to the food-chain and consumer health.

We have also designed solutions that are proven that extend the shelf-life of perishable goods by deactivating bacteria and spores on the produce surfaces in a non-chemical, inert and sustainable way with no damage to product or risk to consumers.
