What is required before opening a fire pump controller to measure voltage and amps?

Before opening a fire pump controller to measure voltage and amps, it is essential to have training in NFPA 70E, which focuses on electrical safety in the workplace, specifically relating to arc flash hazards. This training includes understanding the potential risks associated with working on or near energized equipment and the proper procedures to mitigate those risks.

Wearing the appropriate personal protective equipment (PPE) is a critical aspect of safely performing tasks involving electrical systems to protect against electrical shock, arc flash, and other potential hazards. NFPA 70E outlines the required PPE based on the assessed level of risk involved in the task at hand. This ensures that individuals who are performing such measurements are prepared to protect themselves adequately against any electrical incidents.

While other options present valuable components of safety in an electrical environment, none encapsulate the specific focus on the risks associated with arc flash and the necessity of proper PPE as thoroughly as NFPA 70E training does. This specialized training is crucial for safely working with fire pump controllers and other high-voltage equipment.
