What material must the sauna room warning notice be constructed from?

The sauna room warning notice must be constructed from approved material as specified in the North Carolina Mechanical Code. This requirement ensures that the signage is durable, weather-resistant, and effective in conveying important safety information in the specific environment of a sauna, where conditions can be hot and humid.

Using approved materials means that the signage will not only remain legible and intact over time but will also adhere to safety regulations established by the code. This can include materials that are non-combustible or resistant to moisture, contributing to both safety and longevity in a sauna setting.

While options like plastic, wood, or metal might be considered for signage, they may not all meet the required standards that "approved material" encompasses. Therefore, the focus on using approved materials ensures compliance with broader safety standards and promotes user awareness of the potential hazards associated with sauna use.
