How is the federal government reacting to the December 2026 legislation change lowering workplace exposure standards for diesel particulate?

Key concern: federal legislation only directly covers workers under federal awards; states may have their own legislation and could ignore federal limits. This is the topic for the next WatsON Safety episode.
