OSHA Issues New Arc Flash Safety Guidance

The Occupational Safety and Health Administration (OSHA) has released its first major update on arc flash safety in nearly two decades, addressing critical gaps in protection for workers exposed to arc flash hazards. This is a pivotal moment to reaffirm commitment to worker safety.

Why This Matters

Arc flash hazards are a severe safety risk for workers dealing with energized electrical equipment. Without proper PPE, injuries from molten metal, burns, and explosions can be life-threatening. OSHA’s new guidance is a major step forward in addressing these risks, ensuring workers are adequately protected.

Until this update, over 600,000 workers lacked the necessary PPE to shield themselves from arc flash hazards, even though industry standards like NFPA 70E have long emphasized the importance of flame-resistant and arc-rated (AR/FR) clothing.

Key Highlights of OSHA’s Guidance

OSHA’s updated guidelines aim to tackle two leading causes of arc flash injuries:

1. Improper Assumptions About Deenergization: Many tasks assumed to be deenergized don’t meet OSHA or NFPA 70E standards. OSHA stresses that deenergizing equipment without proper lockout/tagout (LOTO) procedures doesn’t eliminate arc flash or shock hazards. Workers still need AR/FR clothing and PPE for these tasks.

2. The Myth of Low-Voltage Safety: Contrary to popular belief, low-voltage systems (e.g., 120/208V, 277V) can sustain arc flashes. OSHA’s guidance underscores that all energized work over 50 volts requires proper PPE, including AR/FR clothing, to mitigate risks.

The guidance includes comprehensive resources for employers and workers, from detailed documents outlining best practices to quick reference materials for on-the-job use.

The Impact on Workers and Employers

The timing of this update is significant. As the U.S. accelerates its investment in electrification—expanding the grid, electric vehicle infrastructure, and renewable energy projects—more workers are being exposed to arc flash risks. Many of these workers are new to the field and may lack the training and experience needed to recognize and mitigate hazards.

By clarifying PPE requirements and emphasizing safety protocols, OSHA’s guidance aims to better prepare employers and protect employees.

What’s Next?

For workers and employers alike, adapting to these guidelines is essential. Properly assessing risks, equipping workers with AR/FR clothing, and adhering to lockout/tagout standards are non-negotiable steps to ensure safety.As a manufacturer of FR apparel and electrical PPE, we are committed to helping employers navigate these changes. Our gear is designed to meet OSHA and NFPA standards, offering the ultimate protection for workers facing arc flash hazards.

Let’s work together to create safer workplaces and protect the people who power our nation.
