What color label is typically used for flammable substances?

The color red is commonly associated with flammable substances in various safety systems and labeling standards. This color signals immediate attention and caution, indicating that the material can easily ignite and pose a fire risk. It helps in quickly identifying hazardous materials, which is essential in environments where safety is a priority, such as laboratories, warehouses, and manufacturing facilities.

The use of red for flammable substances is consistent in many regulatory frameworks, including OSHA (Occupational Safety and Health Administration) standards, which help enforce safety protocols to prevent accidents and injuries. In contrast, other colors like green typically indicate safety or first aid, blue often designates information or caution, and yellow may indicate caution or potential hazards that are not necessarily fire-related. Thus, the use of red for flammable substances is an established standard that aids in effectively communicating the dangers associated with these materials.
