This question explores the Risk Identification and Assessment competency through the lens of Physical Hazards. A physical hazard is a condition of the property that increases the likelihood or severity of a loss. Knob-and-tube wiring is one of the most significant physical hazards in property insurance.

As part of the RIBO Level 1 Blueprint, a broker must understand why certain building features are "material facts." Knob-and-tube wiring (Option B) was designed for a time when electrical loads were very low (e.g., a few light bulbs). Modern electronics and appliances place a heavy "draw" on these old systems, causing them to overheat. Additionally, the insulation around these wires often becomes brittle and flakes off over 50+ years, leaving bare wires exposed inside wooden walls.

When a broker identifies such a risk, they must use Consulting and Advising to inform the client that most standard insurers will refuse the risk or require the wiring to be replaced within a specific timeframe (usually 30–60 days). Failing to disclose this wiring to the underwriter would be Misrepresentation under Statutory Condition 1, which would void the policy. The broker’s role is to help the client understand that the insurer is not being "difficult," but is protecting themselves against a statistically high probability of a total fire loss. Understanding these technical hazards allows the broker to classify the risk correctly and approach specialized markets if the standard markets decline, thereby demonstrating their value in the Risk Assessment process.
