Safety concerns related to using aluminum strips for flooring include potential slip hazards, especially in wet conditions, due to the smooth surface of aluminum. There's also a risk of electrocution if the aluminum comes into contact with electrical wiring or outlets. Additionally, aluminum can conduct heat and cold, making the floor uncomfortable underfoot in extreme temperatures. The material may also dent or scratch easily, posing a tripping hazard. Lastly, concerns about the long-term health effects of aluminum exposure, though not fully proven, should be considered.
