Exposure assessment and storage capacity
ASP written lesson, 10 min read. ASP Domain 1: Mathematical Calculations
AI-drafted from the cited rules and fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.
What you'll learn
- Compute an 8-hour equivalent exposure from sampling periods
- Calculate a mixture Em and compare it to unity
- Size secondary containment using the 10% or largest-container rule
- Identify which containers may be left out of the containment calculation
- Avoid the common divisor and comparison errors in all three
What this lesson covers
This lesson shows how to turn sampling data into an 8-hour exposure, test a chemical mixture against unity, and size secondary containment for container storage. These are the three calculations the exam reuses most and the ones that go wrong on the job when a divisor or a comparison is misread.
