Which color indicates a physical hazard in HMIS?

The correct answer is orange, which signifies a physical hazard in the Hazardous Materials Information System (HMIS). This color is used to alert individuals to the presence of materials that pose physical hazards, such as the potential for fire, explosion, or other dangerous reactions that can occur when handling or coming into contact with certain substances.

Using color coding like orange is crucial for quick identification and communication of hazards in environments where safety is a priority. The utilization of a standardized color system helps ensure that all employees and responders understand the nature of the risk involved without needing extensive training. This enhances safety protocols and contributes to an overall culture of safety awareness in workplaces handling hazardous materials.
