When working with electrical enclosures, safety should always be a top priority. And unfortunately, electrical accidents can result in property damage, severe injuries, and even fatalities. Luckily, Permanent Electrical Safety Devices (PESDs) have significantly enhanced electrical safety in industries worldwide. So keep reading because this blog post will discuss how PESDs can improve electrical safety and productivity.

What are Permanent Electrical Safety Devices (PESDs)?

PESDs are permanently mounted devices capable of validating energy presence using voltage indicators. These devices help ensure all electrical systems are safe for maintenance and repair work, as required by NFPA 70E/CSAZ462. PESDs are designed to improve safety and productivity in the workplace by minimizing the risk of electrical accidents.

  1. How do PESDs improve electrical safety and productivity?

    PESDs enhance compliance with NFPA 70E Article 120.5, which requires an absence of a voltage tester to verify an electrically safe work condition. To comply with this standard, maintenance professionals perform lockout/tagout (LOTO) procedures, yet unfortunately, these are lengthy, complex, and can pose arc flash and shock hazards. For this reason, LOTO is one of OSHA's most cited violations each year. PESDs make compliance more accessible and safer, and help reduce the margin of human error,

By allowing maintenance personnel to verify energy presence and absence of voltage more quickly and efficiently, PESDs can significantly reduce the time it takes to perform LOTO procedures, saving companies time and money and improving overall productivity.
