Which type of dwellings is exempt from the sauna heater warning notice requirements?

One- and two-family dwellings are exempt from sauna heater warning notice requirements due to the unique nature of the residential environment they provide. In a residential setting, the occupants are typically more familiar with the use and maintenance of sauna equipment since they are personally invested in the space. This familiarity often reduces the need for formal warning notices that may be necessary in larger, more complex buildings where multiple tenants or users might not have the same level of knowledge about operating and maintaining such equipment safely. Smaller dwellings tend to have a more intimate and controlled setting, allowing for a greater understanding of safety among residents.

In contrast, high-rise buildings, commercial properties, and apartment complexes often house a larger and more diverse population, which increases the importance of formal safety notices. These types of dwellings might have numerous users who are not as accustomed to the equipment, thus necessitating the need for clear warnings to prevent misuse and ensure safety. Consequently, the exemption specifically applies to one- and two-family dwellings, reflecting their unique characteristics and lower risk factors associated with sauna heater usage.
