What label must be placed on containers of asbestos waste?

The label that must be placed on containers of asbestos waste is "Danger: Contains Asbestos." This label is mandated because asbestos is a known hazardous material that poses serious health risks, including lung cancer and asbestosis, when inhaled. Indicating "Danger" clearly communicates the seriousness of the hazard, which is essential for ensuring proper handling and disposal procedures.

Labels like "Warning: Contains Hazardous Material" or "Warning: Toxic Substance" may convey a general sense of caution, but they do not specifically identify asbestos, which has unique risks. Similarly, "Caution: Handle with Care" lacks the urgency needed for hazardous materials. Therefore, the correct label must be direct and explicit about the presence of asbestos to ensure that individuals handling these materials recognize the potential dangers involved.
