Scrutinising UV
At the time of writing, towards the end of February, the UK government has just announced its ‘cautious but irreversible’ four-step plan for easing Covid restrictions. 21 June is the target – but the earliest – date that the UK plans to remove legal requirements on social contact and re-open all sectors of the economy. The pandemic will have lasting effects,
with one of those being how we think about disease transmission and the need to protect the vulnerable. We may think twice about travelling to the office when ill, for example, or we may sanitise our hands more regularly while out and about. UV disinfection has been talked about throughout the pandemic as a tool for preventing the spread of covid-19, particularly for use in crowded places with frequently-touched surfaces, such as airports. However, with UV devices being sold without much regulation, there are countless issues regarding the safety and effectiveness of such instruments. UV wands in particular, which users can wave briefly over a surface without delivering a sufficient light dose, are ‘no better than toys’, according to Robert Yeo, director at Pro-Lite Technology. In the feature on page 10, Andy Extance discusses how testing techniques can help producers and users ensure UV-based virus-fighting equipment really works.
