Dekra Diag'Air, new indoor air quality control solution from Dekra Industrial

The goal? Fight even more effectively against airborne transmission of SARS-CoV2 in poorly ventilated confined spaces.

A first test has been launched in real conditions in a restaurant in Arras since May 18, 2021. DEKRA Industrial is the first player in its sector to offer such a solution.

The CO2 rate: a key indicator for the fight against SARS-CoV2

According to the High Council of Public Health (HCSP), the concentration of carbon dioxide (CO2) is the first indicator of the air renewal rate: a concentration greater than 800 ppm in an enclosed space should automatically lead to a reduction the number of occupants and increased ventilation and ventilation.

The control of the operation of the heating, ventilation, air conditioning and refrigeration installations of public buildings is therefore a prerequisite for any sanitary protocol.^[2].

Based on these recommendations, DEKRA sets up the Diag'Air assessment, a three-step protocol intended for ERP:

• Assessment of practices in place in the establishment
• Drafting of a report with conclusions and recommendations aimed at minimizing the risk of transmission of SARS-COV-2
• Installation of one or more COZY AIR connected sensors with monitoring of the CO2 rate, temperature and humidity. Live reporting via an application with an alert system in the event of exceeding the recommended rates
• Intervention of DEKRA Industrial in the event of repeated alerts by examining the functioning of the ventilation systems and by implementing additional measures to combat the pollution observed.

A first test phase in a restaurant in ARRAS

Ahmed Mad has a catering establishment in Arras. Concerned about preserving the health of its customers and its team, its restaurant bar, BADABOOM, has been the subject of a test phase for the DEKRA Diag'Air assessment since May 18.

“It is above all a question of mobilizing to put an end to the virus and the current crisis! Air quality control is actually part of a set of solutions that we had already put in place since the end of the first deconfinement, such as distance from tables, the provision of hydroalcoholic gel or free masks. Thanks to this solution, we are able to provide additional protection to staff and users. "

The presence of connected sensors makes it possible to analyze the air quality in real time and act instantly against the factors of propagation of the virus since the integrated indicator lights provide readable and visible information on the CO2 concentration in the room.

The advantage is threefold:

• In the event of an abnormal concentration, the operator can act on the ventilation of the room or limit the attendance gauge,
• Customers are informed of the air quality at time T via the sensor LEDs
• Employees benefit from a simplified reading of their work environment.

In addition to the inventory report issued at the end of the assessment, DEKRA Diag'Air offers the possibility of engaging in a transparent dialogue with its stakeholders since the measurements taken by the sensor can be interfaced directly on a site. web user. In order to promote ERP engagement, DEKRA also provides them with signage dedicated to the general public.
