Red Seal Insulator (Heat and Frost) Practice Exam

What should be done to insulation that has been exposed to water damage?

1. It should be removed and replaced

2. It should be dried out and reused

3. It should be treated with chemicals

4. It should be painted to protect it

The correct answer is: It should be removed and replaced

Insulation that has been exposed to water damage often becomes a breeding ground for mold and bacteria, compromising its effectiveness and potentially creating health hazards. The best course of action in this situation is to remove and replace the damaged insulation. This approach ensures that any contaminants, such as mold spores, are effectively dealt with. Even if the insulation is dried out, it may still retain moisture, leading to deterioration or reduced insulating properties. Chemical treatments or painting may not offer a permanent solution and could mask underlying issues rather than resolving them. Therefore, removal and replacement provide a clean slate, ensuring the integrity and performance of the insulation system.
