Which of the following does not pose a risk according to OSHA standards?

The choice of accidentally discarded chemicals being identified as not posing a risk according to OSHA standards is correct. Proper procedures for hazardous waste disposal are essential for workplace safety, and accidents involving discarded chemicals can lead to exposure to harmful substances, spills, or environmental contamination. This highlights the importance of appropriate disposal methods and ensuring that all chemicals, even those that have been discarded, are managed according to safety protocols.

In contrast, safely stored corrosives and properly labeled chemicals are crucial practices outlined by OSHA to mitigate risks. Safe storage helps prevent accidents and exposure, while proper labeling ensures that workers are informed about the hazards and safe handling procedures of the chemicals they may encounter. The assertion that all chemicals have inherent risks aligns with OSHA's perspective that every chemical can pose some level of hazard; hence, proper training and management are critical to minimize these risks.
