Fieldlab focused on four different types of events:
• Type I – Indoor events with a passive audience
• Type II – Indoor events with an active audience
• Type III – Outdoor events with an active audience
• Type IV – Outdoor events with an audience that can move around freely (festivals)
This distinction has been introduced so that generic recommendations can be made for the different types of events, taking air quality and visitor dynamics into account. In the documents attached below, Fieldlab presents the data collected during their pilot events.
The maximum numbers as indicated in former versions of the roadmap should be revised with Fieldlab’s recommendations. The generic measures, including the 1.5 metre distance, can be substituted within the location by pre-event or access tests and other recommended measures.

Based on the data collected and the risk model, Fieldlab Events will demonstrate that with these measures, outdoor events do not present any additional risk of increasing the spread of the virus or hospitalisations. These measures are based on the building blocks as applied and described in the research approach entitled Pilots for ‘LowContact Events’ of Fieldlab Events.
As a basis, a risk model has been developed that answers the question of what the risk of COVID-19 contamination or hospitalisation is for visitors, in comparison with other situations in daily life. The risk model calculates the influence of various measures that can be taken.
Below are both of Fieldlab’s documents on recommendations regarding the reopening of events.
