Certified Facility Manager (CFM) Practice Exam

Which of the following is characterized as a corrosive substance?

1. Soaps and detergents.

2. Acids and bases.

3. Ovens and microwaves.

4. Greases and oils.

The correct answer is: Acids and bases.

The classification of corrosive substances is critical in facility management, particularly when addressing safety protocols and proper handling procedures. Acids and bases are recognized as corrosive because they can cause damage to materials, including metals, plastics, and human tissue. This corrosive property arises from their chemical nature; acids typically release hydrogen ions (protons) in solution, while bases release hydroxide ions. This ability to react strongly with various materials can lead to degradation and serious safety hazards if not managed appropriately. In contrast, soaps and detergents often serve as cleaning agents without inherently damaging surfaces, and while they can have some mild corrosive effects on particular materials under specific conditions, they are generally not categorized as corrosive substances. Similarly, ovens and microwaves are appliances used for cooking and do not possess corrosive characteristics themselves. Lastly, greases and oils are primarily used for lubrication and do not exhibit corrosive properties; rather, they help prevent wear and tear on moving parts. Understanding these distinctions is crucial for effective facility management and ensuring the safety of both personnel and equipment.
