What type of hazards does NFPA 70E address?

The correct choice focuses on electrical hazards, which are specifically addressed by NFPA 70E. This standard is critical for ensuring the safety of individuals who work on or near electrical equipment. It provides guidelines and practices to mitigate risks associated with electrical exposure, such as arc flash and shock, which can occur in various electrical work environments.

NFPA 70E outlines requirements for safety-related work practices, proper use of personal protective equipment (PPE), and detailed procedures for working on energized electrical components. By doing so, it helps prevent accidents and injuries that could arise from the inherent dangers of working with electricity, ensuring that workers can perform their tasks safely and effectively.

The other options, while also important areas of safety, do not fall under the purview of NFPA 70E. Chemical storage hazards, biological hazards, and mechanical hazards are governed by different standards and regulations that focus specifically on those risks.
