Exposure, noise, containment and lifting math
CSP video lesson, 6:27. 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.
Work the CSP calculations: 8-hour TWA, mixture Em, noise dose and TWA, containment capacity, and the NIOSH recommended weight limit, each tied to its primary source formula.
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: compute an 8-hour TWA and a mixture Em, find a noise dose and convert it to a TWA, size containment for stored containers, and calculate a NIOSH recommended weight limit and a lifting index. Subpart Z gives two formulas for air contaminants. The 8-hour equivalent exposure is the sum of each concentration times its hours, divided by 8.
