Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, what assessment her Department has made of the potential merits of companies' covid-19 risk assessments including provision of covid-19 fogging equipment.

COVID-19 risk assessments fall under the Health and Safety Executive (HSE) remit. As each workplace is different, it is for an employer to identify, as part of their risk assessment, how to control COVID-19 transmission. Guidance has been produced by HSE that gives advice and information to employers on how to do such an assessment and manage the risk from COVID-19 in a proportionate manner.

Frequent surface cleaning is one of several control measures that can be implemented to manage the transmission risk. Fog, mist, vapour or UV (ultraviolet) treatments may be suitable options to help control the spread of coronavirus and disinfecting a larger space or room when people are not present. Any use of these treatments for these purposes should form part of your COVID-19 risk assessment. Users must be competent and properly trained. HSE provides guidance on its website as to when using these systems may be appropriate. Airborne disinfection does not remove the need for surface cleaning and surfaces that are dirty can reduce the effectiveness of disinfectant applied by airborne dispersion.

HSE and public health bodies in England, Wales and Scotland have agreed joint advice for dutyholders considering using walk-through spraying or misting disinfecting systems to reduce transmission of coronavirus (COVID-19). Spraying people with disinfectants in this way is not recommended under any circumstances (including in a tunnel, cabinet, or chamber).
