Which of the following is a chemical hazard?

A chemical hazard refers to substances that can cause harm through chemical reactions or by being toxic in some way when ingested, inhaled, or come into contact with the skin. Cleaning agents are a clear example of chemical hazards, as they often contain strong chemicals that can pose serious health risks, such as burns, respiratory problems, or other reactions if not handled properly.

Understanding the nature of chemical hazards is important in settings where food is prepared, handled, or served, as safety protocols must include proper storage, labeling, and usage of such substances to prevent accidents and ensure public health.

Bacteria, parasites, and glass do not qualify as chemical hazards. Bacteria and parasites are biological hazards, as they are living organisms that can cause foodborne illnesses. Glass is a physical hazard, as it poses a risk of injury from cuts or choking rather than chemical exposure.
