OSHA letters of interpretation released in 2025 aim to ensure consistent and transparent application of federal workplace safety and health standards across the United States. In total, seven interpretation letters were issued during the year, offering clarity to employers on how specific OSHA regulations should be applied in real-world situations.

These letters serve as an important compliance resource, helping employers better understand their responsibilities under workplace safety laws.

Focus on Permit-Required Confined Spaces

The first letter issued in 2025 addresses permit-required confined spaces. This guidance clarifies employer obligations when workers are exposed to confined environments that present serious safety and health risks.

Clear interpretation in this area is critical, as confined space hazards remain a leading cause of serious workplace injuries and fatalities.

Additional Topics Covered in the OSHA Letters of Interpretation

The remaining letters address a range of technical and operational safety issues, including:

• Training requirements for powered industrial truck operators
• Use of software solutions for OSHA recordkeeping compliance
• Engineering controls for exposure to benzene and 1,3 butadiene
• Stairway angle and tread depth requirements

These topics reflect common areas where employers often seek clarification to maintain compliance with OSHA standards.

OSHA’s Approach to Employer Guidance

According to Deputy Labour Secretary Keith Sonderling, the interpretation letters demonstrate OSHA’s commitment to listening to employer feedback and providing decisive regulatory guidance. He stated that the opinion letter programme has already proven effective across industries, from construction to engineering.

This approach supports the broader goal of educating employers and enabling them to protect workers through informed safety practices.

Ongoing Access to Interpretation Letters

Selected OSHA letters of interpretation, or excerpts from them, are published in the monthly OSHA Up to Date newsletter. This allows employers and safety professionals to stay informed about evolving interpretations without navigating complex regulatory language.

Regular review of these updates helps organisations adapt their safety programmes and maintain compliance with federal standards.

Why These Letters Matter for Employers

Understanding OSHA letters of interpretation is essential for employers seeking to apply safety regulations correctly. These documents reduce uncertainty, support consistent enforcement and help organisations implement practical safety solutions aligned with regulatory expectations.

Employers who stay informed can better manage risk, avoid violations and create safer working environments.

Workplace Safety Resources and Compliance Support

In addition to regulatory guidance, organisations such as OSHAssociation.org provide valuable resources focused on occupational safety and health education. Access to trusted safety information helps employers align their workplace policies with regulatory expectations and promote a strong culture of compliance and prevention.
