OSHA Citation & Interpretation Viewer

Highlight regulatory citations on any webpage and view official letters of interpretation directly on osha.gov. OSHA Citation & Interpretation Viewer is a utility extension designed for EHS professionals, safety managers, and compliance officers. It reduces the need for manual cross-referencing by rendering regulatory text and interpretation letters directly within your active browser tab. Features * Embedded Interpretations on osha.gov: Detects matches between standard paragraphs on official OSHA pages and a bundled index of Letters of Interpretation. Click the envelope icon next to a paragraph to read the corresponding guidance in a sidebar. * Citation Identification: Scans text nodes on loaded webpages for standard CFR patterns (e.g., "29 CFR 1910.134"). Detected citations are styled as active links; clicking them fetches and displays the relevant regulation text in a sidebar. * CORS-Compliant Fetching: Uses a background service worker to query the eCFR.gov API and load regulation text on demand. Benefits * Minimize Tab Switching: View referenced standards and official interpretations without navigating away from your active page. * Streamlined Document Scanning: Instantly identify regulatory cross-references in dense technical text.
