Testing for radon in multi-tenant commercial and industrial properties presents unique challenges that make them more complicated than testing a single-family home or even other commercial properties. The sprawling design and complex ventilation systems found in large retail centers, factories, and industrial plants require extensive planning and coordination between testers, building managers, and tenants to ensure optimal testing conditions. As per AARST’s protocol for measuring radon in large buildings, testing should be done in areas of significant occupancy during all times of day, including waiting rooms/lobbies, offices, warehouses, and other regularly occupied spaces.
Some of the greatest challenges for testing in multi-tenant properties include the need to minimize operational disruptions, ensure HVAC and building systems are set to optimal conditions for testing, and coordinate with tenants and building managers. Furthermore, as different businesses occupy different areas within the building, it is important to gain access to all areas for testing. To address these challenges, it is crucial for testers to work closely with building managers to obtain floor plans, schedules, and access to all areas. Additionally, proper communication with tenants is essential to inform them of the testing and ensure their cooperation with testing protocols.
