According to the 1938 Building Code, Class 3 Construction is defined as?

Class 3 Construction, according to the 1938 Building Code, is defined as Non-Fireproof. This classification highlights that structures under this category do not possess the same level of fire resistance as fireproof buildings. In Non-Fireproof construction, materials used typically do not include fire-rated assemblies or resist significant fire exposure.

Understanding Class 3 Construction is particularly important because it informs firefighters about the potential hazards they may encounter during a response. Buildings that fall under this classification could involve greater risks during a fire because they may not adequately withstand high temperatures or fire spread. Firefighters need to be aware of these characteristics to make informed decisions about tactics, especially concerning ventilation and suppression strategies.

The other classifications, while relevant to the overall building code, do not accurately describe Class 3 construction. Fireproof structures are designed specifically to resist fire for extended periods, which is not applicable here. Wood frame buildings are typically associated with residential construction and can fall under different classifications based on their fire resistance features. Reinforced concrete does indicate a higher level of structural integrity and fire resistance, contrasting them with Non-Fireproof classifications.
