“Enhancing Electrical Safety: Updates on NFPA 70E and Safety News”


The National Fire Protection Association (NFPA) plays a vital role in saving lives and reducing loss caused by fire and electrical hazards. They have developed almost 300 standards and codes to minimize risks. One such standard is NFPA 70E, which focuses on electrical safety in the workplace. It covers protection against hazards like shock, arc flash, and electrocution. NFPA 70E is dependent on NFPA 70 and NFPA 70B, which address electrical codes and equipment maintenance respectively. The standard emphasizes the use of the Hierarchy of Hazards to control exposure. It also requires a thorough risk assessment and evaluation of electrical equipment for shock and arc flash risks. Additionally, NFPA 70E provides detailed requirements for preventing, responding to, and protecting workers from arc flashes. Another significant aspect covered by NFPA 70E is lockout/tagout procedures, which use physical locks and tags to prevent employees from servicing live machines. Understanding and implementing NFPA 70E is crucial for electrical contractors, engineers, and other professionals to ensure worker safety and prevent accidents and injuries.

Protecting Workers from Electrical Hazards: The Importance of NFPA 70E

In their mission to save lives and reduce loss, the National Fire Protection Association (NFPA) has developed nearly 300 standards and codes to eliminate risks and minimize the harm caused by fire, electrical, or related hazards. Among them, NFPA 70E stands out as a crucial standard titled the “Standard for Electrical Safety in the Workplace.” This code establishes requirements that protect workers from electrical hazards such as shock, electrocution, arc flash, and more. Let’s take a closer look at why NFPA 70E is essential for workplace safety.

The Dependence on NFPA 70 and NFPA 70B

NFPA 70E is dependent on two other important codes: NFPA 70, also known as the National Electrical Code, and NFPA 70B, Recommended Practice for Electrical Equipment Maintenance. While these codes provide general guidelines and maintenance practices, it is NFPA 70E that goes into detail regarding safe work practices, making it a critical resource for electrical safety in the workplace.

The Hierarchy of Hazards

NFPA 70E stresses the importance of controlling hazard exposure in the workplace. One effective strategy recommended by the code is to utilize the Hierarchy of Hazards. The first and most effective control strategy is eliminating the hazard completely from the area. However, this may not always be possible. The next best option is substitution, which involves replacing a high voltage machine with a less hazardous one. Engineering controls, such as machine guards and design features that isolate workers from hazards, are the next level of control. The last two types of controls recognized, administrative controls (training, work procedures, etc.) and personal protective equipment (PPE), are the least effective but still play a role in minimizing hazards.

Risk Assessment and Facility Evaluation

Prior to beginning work, NFPA 70E requires a risk assessment and evaluation of the facility for electrical hazards. During the risk assessment, it is important to tour the facility and identify any electrical or safety issues that need to be addressed. For each hazard identified, potential exposure controls should be evaluated and implemented based on their effectiveness. Furthermore, any electrical equipment that poses a danger to workers must be assessed for shock risk and arc flash risk to ensure proper preparation for emergencies.

Preventing and Responding to Arc Flashes

Arc flashes, which are a type of electrical explosion, are considered one of the most dangerous occupational hazards. NFPA 70E provides extensive requirements for preventing, responding to, and protecting workers from arc flashes. This includes calculations for shock boundaries, specifying required personal protective equipment (PPE), and providing a guide for determining the Hazard/Risk Category. These measures are crucial in preventing death, burns, concussions, permanent hearing damage, and other serious injuries caused by arc flashes.

The Importance of Lockout/Tagout

Another key component covered by NFPA 70E is the lockout/tagout (LOTO) procedure. LOTO relies on visual cues, such as physical locks and tags, to prevent employees from performing maintenance or servicing energized machines. In this system, individuals working on a machine must disconnect all energy sources and ensure that stored energy is released. A lock or tag is then affixed to the equipment, indicating that it is being worked on and cannot be powered up. An effective LOTO program includes written procedures for electrical systems, documented training for employees, the appropriate equipment, and necessary PPE.

Crucial for Electrical Industry Professionals

Understanding NFPA 70E is vital for electrical contractors, electricians, engineers, and other industry professionals. Given the inherent dangers of working with electricity, this standard plays a critical role in protecting workers from shocks, burns, and other injuries while on the job.


With its comprehensive guidelines on electrical safety in the workplace, NFPA 70E is an indispensable standard that safeguards workers from electrical hazards. By following its requirements, implementing appropriate control measures, and prioritizing safety, employers can create a secure working environment for their employees.

Summary: “Enhancing Electrical Safety: Updates on NFPA 70E and Safety News”

The National Fire Protection Association (NFPA) has developed numerous standards and codes to enhance safety and prevent losses caused by fire and electrical hazards. One of these is NFPA 70E, titled the Standard for Electrical Safety in the Workplace, which focuses on protecting workers from electrical dangers such as shock, electrocution, and arc flash. The code emphasizes the importance of controlling hazard exposure and utilizing the Hierarchy of Hazards, which includes eliminating hazards, substitution, engineering controls, administrative controls, and personal protective equipment. NFPA 70E also requires risk assessments and evaluations of electrical equipment to ensure worker safety. Additionally, it provides extensive guidelines for preventing arc flashes and implementing effective lockout/tagout procedures. Electrical professionals must be familiar with NFPA 70E to safeguard workers from electrical accidents.
