"粉尘危害" can be translated into English as "dust hazard" or "hazard from dust".
"Dust hazard" is a concise and commonly used expression in occupational health and safety contexts to refer to the potential risks or dangers associated with dust exposure.
"Hazard from dust" provides a slightly more descriptive version, emphasizing the source of the hazard (i.e., dust).
Both translations are accurate and can be used depending on the specific context and desired level of detail.
