Identify the statement that is NOT TRUE about hazard of contents classification.

• A. The contents in most common occupancies are classified as ordinary.
• B. Ordinary hazard contents include areas where flammable liquids are handled, used, or stored under conditions involving possible release of flammable vapors.
• C. General requirements in the Life Safety Code are written for ordinary hazard contents classification.
• D. Low-hazard contents are classified as those of such low combustibility that no self-propagating fire can occur.

Answer: (B)

Hazard of contents classification is about how the materials inside a space influence fire growth and the protection needed. Ordinary hazard contents cover materials that burn at a moderate rate—think typical office supplies, paper, fabrics, and similar items found in many common occupancies. Areas where flammable liquids are handled, used, or stored with a possible release of vapors pose a much higher ignition and flame-spread risk, so they fall into a higher hazard category, not ordinary. That’s why describing ordinary hazard contents as including areas with flammable liquids and vapors isn’t correct.

Context helps: the Life Safety Code sets different protection levels based on hazard class, which affects sprinkler design, door and wall ratings, and other safeguards. Low-hazard contents are those with such low combustibility that a self-propagating fire cannot occur, which aligns with a minimal protection approach.
