Air contaminants and respirable silica
CSP video lesson, 6:44. CSP Domain 6: Occupational Health and Applied Science
Narrated with an AI-generated voice. The script is AI-drafted from the cited rules and fact-checked against them.
General industry air contaminant limits and the respirable crystalline silica standard: TWA and ceiling limits, the mixture formula, the 50 and 25 microgram limits, monitoring schedules and medical surveillance.
Included with every CSP pass, with captions, chapters and the full transcript. Every rule and number is cited on screen to its primary source.

What this lesson covers
In this lesson, you'll learn to: apply TWA, ceiling and mixture limits under 1910.1000, state the silica PEL and action level, set the monitoring schedule from exposure results, and explain silica medical surveillance and its deadlines. Table Z-1 limits come in two kinds. Look for the letter C. With a C, the ceiling may never be exceeded. If instantaneous monitoring isn't feasible, assess it as a 15-minute average.
