Which symbol is specifically used to denote infectious materials?

The biohazard symbol is specifically designed to indicate the presence of infectious materials. This symbol consists of three interlocking circles and is universally recognized in laboratories, hospitals, and other settings where hazardous biological substances are handled. Its primary purpose is to alert individuals to the potential dangers of biological agents that can pose health risks, such as bacteria, viruses, and other pathogens that may cause infections.

By using the biohazard symbol, healthcare facilities ensure that staff and others are aware of the need for precautions and protective measures when dealing with waste or materials that may be contaminated with infectious agents. This symbol plays a crucial role in promoting safety and preventing the spread of infectious diseases in various environments where health and safety are a priority.
