Permanent electrical safety devices (PESDs) listed to UL 61010: Safety Requirements for Electrical Equipment For Measurement, Control, and Laboratory Use can play a vital role in this process by providing a means to verify the absence of voltage without direct exposure to electrical hazards, thereby supporting compliance with NFPA 70E’s approach to electrical safety.

Specifically, when used with an adequately rated portable test instrument, test point PESDs help in the verification process of the absence of voltage, complementing step seven of the LOTO process by allowing for safer and more efficient verification before and after work is performed. This enhances compliance with NFPA 70E by integrating technology that makes the verification process less invasive and reduces the risk of exposure to electrical hazards.

Compliance with NFPA 70E language: ‘point of work’

PESDs comply with NFPA 70E-2024 language and its emphasis on the “point of work” by providing strategically designed solutions that enhance safety directly at the work site. Their proper placement, compliance with safety standards, role in LOTO procedures and facilitation of safe voltage testing embody the principles of electrical safety at the point of work, ensuring a safer environment for electrical maintenance and repair activities.

Here’s how PESDs align with the “point of work” concept as articulated in NFPA 70E-2024:

• Proper placement and accessibility: PESDs should be installed in locations that are both practical and precise, ensuring that they are readily accessible at the point where electrical work is conducted. This placement is pivotal for maximizing their effectiveness in promoting electrical safety and aligns with the “point of work” concept by mitigating risks directly where the electrical work occurs.
• Compliance with NFPA 70E requirements: PESDs and other test point devices are recognized as compliant with the safety standards set by NFPA 70E. They provide a safe and efficient method for verifying the absence of voltage, which is a crucial step in establishing an electrically safe work condition. Their design and application are in harmony with the NFPA 70E’s emphasis on verifying an electrically safe work condition at each point of work, underscoring their role in adherence to updated safety protocols.
• Enhanced safety during LOTO procedures: Incorporating visible PESDs such as voltage presence indicators and absence of voltage test points can significantly reduce risks during LOTO procedures. By enabling effective and reliable verification of voltage status within an electrical panel or system, PESDs serve as an additional layer of protection, ensuring that workers can make informed decisions about the safety of their work environment. This is particularly relevant to the “point of work,” where ensuring the absence of hazardous energy is paramount.
• Facilitating safe and accurate absence of voltage testing: The NFPA 70E revisions validate the use of impedance-protected test points, a feature of many PESDs, for absence of voltage testing. This functionality is critical for safely establishing an electrically safe work condition, directly supporting the “point of work” philosophy by enabling precise testing at the location of the electrical work.

As industries continue to evolve and electrical systems become more complex, the need for comprehensive safety standards that address the realities of modern electrical work is paramount. The NFPA 70E 2024 updates, with their focus on “point of work” safety, PESDs and enhanced LOTO procedures, represent a significant step forward in meeting this need. By adhering to these standards and embracing the technologies and practices they advocate, employers and safety professionals can ensure that their electrical safety programs are not just compliant, but truly effective in protecting workers from harm.

Rethinking risk with the hierarchy of controls

One of the cornerstones to any electrical safety program is the approach to the hierarchy of controls. Traditionally, this hierarchy has guided employers and safety professionals to prioritize elimination and substitution over administrative controls and personal protective equipment (PPE).

PESDs are an essential part of the engineering controls within the hierarchy of controls in industrial safety. The hierarchy of controls is a system used in occupational health and safety to minimize or eliminate exposure to hazards. It is represented as a pyramid with the most effective methods of control at the top and the least effective at the bottom. Here’s where PESDs fit in:

1. Elimination: Physically removing the hazard and is the most effective control method. While PESDs don’t eliminate electrical hazards, they significantly minimize the need for interaction with live circuits, indirectly contributing to elimination.
2. Substitution: Substituting hazardous situations with less hazardous ones can be partly achieved by using PESDs, as they can replace more hazardous voltage testing methods that require direct interaction with live circuits.
3. Engineering controls: This is where PESDs are directly applicable. They are designed to isolate workers from electrical hazards by providing a way to verify the presence or absence of voltage without exposing workers to live electrical components. For example, PESDs allow verification from outside a closed electrical panel, reducing the risk of arc flash and shock.
4. Administrative controls: These involve changing the way people work and include safety training and procedure modifications. While PESDs themselves are not administrative controls, they are often incorporated into safety procedures, thus supporting these controls.
5. Personal protective equipment (PPE): This is the last line of defense and the least effective control method. PESDs can reduce the need for PPE by minimizing exposure to hazards, although PPE may still be required during certain operations for additional safety.

By integrating PESDs into electrical safety protocols organizations can significantly enhance their safety measures, align with best practices and comply with standards such as NFPA 70E. These devices are a proactive measure that aligns with the philosophy of designing safety into work practices and the working environment.

Integrating enhanced electrical safety program measures

The integration of PESDs into an electrical safety program represents a significant shift toward safer and more reliable electrical maintenance practices. By providing a means to verify the absence of voltage without exposing workers to live components, PESDs align perfectly with the NFPA’s increased emphasis on “point of work” safety. This approach not only enhances compliance but also significantly bolsters the overall safety and productivity of electrical maintenance operations.
