What color should the containers be when dealing with hazardous materials?

When dealing with hazardous materials, the color coding system is designed to promote safety by allowing for quick identification and understanding of various types of hazards. The correct answer, red, is traditionally associated with the storage and handling of flammable and combustible materials. Using red containers helps ensure that anyone handling or working near these materials can easily and quickly recognize the associated danger, which is critical in preventing accidents and ensuring appropriate safety protocols are followed.

In addition, red is often used universally in safety signage to alert individuals to hazards, making it an intuitive choice for hazardous materials containers. Therefore, using red containers aligns with both established safety practices and regulatory recommendations in managing hazardous substances.
