Navigating OSHA’s Recent Changes to Arc Flash Standards:
What Electric Utilities Need to Know
Written by Ken Lulow
In November 2024, the Occupational Safety and Health Administration (OSHA) released updated guidance on arc flash safety. This update addresses persistent safety gaps and aims to protect workers in the electrical industry from arc flash hazards that can cause severe injuries or fatalities. This article explores the new guidance, its implications, and why these changes are critical for the safety of electrical workers.
What Does the New OSHA Guidance Say?
The new guidance highlights two primary causes of arc flash injuries and fatalities and provides actionable solutions:
Misinterpretation of "De-energized" Work:
De-energized work is not synonymous with Lockout/Tagout (LOTO) or Electrically Safe Work Condition (ESWC). OSHA clarifies that tasks presumed to be de-energized often do not meet these definitions and still require an energized work permit and arc-rated PPE.
The guidance emphasizes the importance of wearing appropriate PPE even during tasks believed to involve de-energized equipment, addressing what OSHA identifies as the second leading cause of arc flash injuries and fatalities in the U.S.
Hazards of Low Voltage Work:
The dangerous myth that low voltage (e.g., 120/208 or 277 volts) is inherently safe is debunked. OSHA stresses that energized work, regardless of voltage, typically requires an energized work permit and PPE as prescribed by NFPA 70E’s Table 150.3(C) or an incident energy study.
The guidance recognizes the hazards associated with low voltage work. “Even 120/208V can create arcs with more than enough energy to burn exposed skin, ignite flammable clothing and cause catastrophic or fatal injuries. Low voltage does NOT justify energized work and requires appropriate arc flash gear.”
Improper Use or Wear of Clothing:
Most arc flash burn injuries happen when an arc ignites flammable clothing and not from the arc itself. “Wearing meltable or flammable undergarments is dangerous and prohibited under 29 CFR 1910.269.”
Who Does the Guidance Apply To?
The updated guidance applies broadly to:
Commercial, Industrial, and Residential Electrical Workers: This includes electricians, line workers, and contractors working on or near energized electrical parts.
Operators and Maintenance Personnel: Those responsible for servicing or operating equipment with exposed energized components, as well as contractors or maintenance personnel working with or near batteries with exposed electrical components are also covered under these requirements.
When Was It Issued, and When Does It Take Effect?
OSHA announced the forthcoming guidance in September 2024 and formally released it in November 2024. The new standards are effective immediately, requiring swift action from employers and electrical professionals to close protective gaps and comply.
Why Did OSHA Update the Standards Now?
OSHA’s updated guidance stems from persistent arc flash injuries and fatalities, despite decades of existing safety standards and proven protective measures. Several factors influenced the timing of this update:
Collaboration with PES and Legislative Bodies: OSHA worked with the Partnership for Electrical Safety, as well as the U.S. House and Senate, to address gaps in compliance and awareness.
Stagnation in Safety Progress: After significant reductions in arc flash injuries following the adoption of NFPA 70E in 2000, the rate of arc flash injuries began to level off around 2010 and continues to report around half of the pre-2000 adoption of the NFPA 70E. This is due in part to many electrical workers and industry professionals who still continue to operate without the necessary PPE.
Increasing Exposure to Hazards: Government investments in infrastructure projects, such as power grid upgrades and electric vehicle charging stations, have increased demand for electrical work, often involving poorly maintained equipment.
NFPA 70B Elevation: The elevation of NFPA 70B from a recommended practice to a prescriptive standard has created a “catch-up” period where electrical workers face heightened exposure to arc flash hazards while upgrading equipment to meet the new requirements.
How Employers and Workers Can Comply
To align with OSHA’s updated guidance, employers and workers should:
Understand What Constitutes De-Energized Work:
Ensure tasks meet the full definitions of lockout/tagout (LOTO) or electrically safe working condition (ESWC). When in doubt, assume the need for PPE and an energized work permit.
Wear Appropriate PPE:
Use PPE compliant with NFPA 70E standards, including arc-rated clothing capable of withstanding identified incident energy levels.
Wear arc-rated clothing properly, shirts tucked in, sleeves rolled down, buttons clasped, and proper under garments.
Integrate Training and Documentation:
Provide comprehensive training on the updated standards, emphasizing the risks of low voltage and misclassified de-energized work.
Maintain detailed records of training, risk assessments, and PPE usage.
Leverage Digital Tools:
Utilize digital resources to track compliance, manage PPE inventories, and conduct risk assessments efficiently.
The Role of Arc-Rated Clothing Manufacturers in Supporting OSHA Arc Flash Compliance
Arc-rated clothing manufacturers like DragonWear and Tyndale play a pivotal role in helping organizations comply with the latest OSHA arc flash standards, ensuring worker safety and adherence to regulatory requirements. OSHA’s updated guidelines emphasize the importance of providing electrical workers with adequate protection against arc flash hazards, which can cause severe injuries or fatalities.
Companies like DragonWear and Tyndale are at the forefront of developing innovative, high-performance arc-rated clothing designed to meet or exceed these safety standards. Their expertise in fabric technology and garment design ensures that workers are equipped with durable, comfortable, and compliant protective gear. By providing products that address various risk categories, these manufacturers enable organizations to align their personal protective equipment (PPE) strategies with OSHA’s stringent requirements.
Moreover, these manufacturers often partner with organizations to provide education on arc flash hazards and proper PPE usage. Their commitment to safety extends beyond the clothing itself, offering resources, training, and consultation services to ensure employers understand and implement the best practices for arc flash protection.
In the face of evolving safety standards, DragonWear, Tyndale, and similar industry leaders continue to play an essential role in creating safer workplaces for electrical professionals, safeguarding lives, and enhancing compliance across the utility and industrial sectors.
Conclusion
OSHA’s November 2024 arc flash guidance addresses critical gaps in electrical safety and reflects a commitment to protecting workers from preventable injuries and fatalities. With immediate implementation required, employers and workers must act swiftly to adopt the new standards.
