What is a potential hazard of using a descaler to clean dropping pans?

1. Respiratory irritation

2. Burns from chemicals

3. Environmental contamination

4. Biological exposure

The correct answer is: Burns from chemicals

Using a descaler to clean dropping pans can pose a risk of burns from chemicals. Descalers typically contain strong acids or bases designed to break down mineral deposits and scale. When these substances come into contact with skin, they can cause chemical burns, resulting in irritation, redness, or more severe injuries, depending on the concentration and exposure duration. While respiratory irritation, environmental contamination, and biological exposure can also be associated risks in laboratory settings, the most direct and immediate hazard when handling descalers would be the chemical burns from skin contact or splashes. Proper personal protective equipment (PPE) such as gloves, goggles, and protective clothing is essential when utilizing such hazardous cleaning agents to mitigate these risks.
