What is considered a fire hazard when storing steel wool?

Storing steel wool poses a fire hazard due to its highly flammable nature, especially when it comes into contact with substances or objects that can ignite a fire. Among the options provided, batteries are particularly relevant in this context because they can create sparks or generate heat, especially if there's a short circuit or if the terminals of the battery accidentally come into contact with conductive materials like steel wool.

When steel wool is stored improperly near batteries, such as in a disorganized manner where the wool can touch the battery terminals, a spark can ignite the wool, leading to a fire. Batteries can also leak or be damaged, which can further increase risks if stored improperly with conductive materials like steel wool.

Keeping a safe distance between batteries and any flammable materials, including steel wool, is crucial to prevent accidents and ensure a safe storage environment. This understanding emphasizes the importance of recognizing potential hazards when handling and storing materials that can easily ignite or exacerbate fire risks.
