Ventilation guidance to protect employees
Posted on 9th December 2020
Since March this year critical ventilation has been supplied to coronavirus wards and field hospitals, including the Nightingale and Rainbow hospitals. This has helped to develop valuable advice on the positive effect of ventilation by improving indoor air quality and creating a healthy environment.
This has now been turned into practical advice on indoor ventilation and why it is important to reduce virus transmission.
How ventilation can help protect against coronavirus
The increased airflow provided by ventilation systems can help to reduce transmission of the virus indoors where it can present a greater risk because there is normally less airflow.
The government has just launched a new public information campaign to highlight how simple measures to ventilate indoor spaces can reduce the risk of coronavirus infection by over 70%. The World Health Organisation (WHO) has also acknowledged the role of ventilation to prevent the virus spreading indoors.
In small areas simply providing better airflow through open doors and windows might provide enough fresh air. However, there are many environments where this isn’t possible, especially during the winter months.
For domestic purposes bathroom and kitchen fans, single room heat recovery, whole house ventilation, and positive input ventilation might be suitable.
check any existing ventilation to make sure it is working as it should
minimal leakage plate counterflow and crossflow heat recovery systems can be used
do not use air recirculation or rotary heat recovery
use the highest setting available to expel air
ventilation system filters don’t typically capture particles as small as viruses and even HEPA filters might not be sufficient
all filters should be cleaned or replaced regularly
regular cleaning schedules for ductwork should be maintained.
MSE is always happy to work with heating, ventilation and air conditioning engineers to provide all the electrical requirements for installations.
