What information must be included in an asbestos warning sign?

The correct choice emphasizes the need for a clear and direct warning that communicates the significant dangers associated with asbestos exposure. A sign stating "DANGER: ASBESTOS" effectively alerts individuals to the serious risks posed by asbestos fibers, which can lead to severe health issues, including lung diseases and cancers.

This type of warning is essential because it ensures that everyone in the vicinity is immediately aware of the hazardous situation and can take appropriate precautions. The inclusion of "and associated hazards" helps to underline the potential dangers that may not be immediately visible, prompting individuals to treat the area with extreme caution.

Other choices may suggest various messages, but they do not carry the same level of urgency or specificity regarding the dangers of asbestos. For instance, mentioning safety precautions or protective gear may imply that the risks can be somewhat managed, which could downplay the urgency of the warning. Additionally, evacuation routes, while important in an emergency plan, are not the primary focus of an asbestos warning sign, which should prioritize immediate recognition of the health hazards presented by asbestos exposure.
