The primary danger associated with aluminum-clad polyethylene panels in construction lies in the fact that they can liquefy and ignite when exposed to heat. These panels typically consist of a thin layer of aluminum on the outside, which can be misleading in terms of their fire resistance. While aluminum is a metal that can withstand some heat, the polyethylene material within can easily become combustible and melt when subjected to flame or high temperatures.

This liquefaction process can lead to significant hazards during a fire situation. As the polyethylene softens and melts, it can drip and create additional sources of fuel for the fire, potentially spreading the flames and complicating firefighting efforts. This characteristic is critical for firefighters to understand, as it implicates the potential for rapid fire spread and increases the overall risk to both life and property during a fire incident.

In contrast, the other options highlight elements that, although related to the panels, do not encapsulate the primary hazard effectively. For instance, being resistant to high temperatures suggests a level of safety that is misleading in this context. Similarly, while harmful gases can be produced from burning materials, the more immediate concern in the case of aluminum-clad polyethylene panels is their propensity to ignite and release burning polyethylene. The non-combustibility
