Predicting PID, O2 and LEL Readings:

PID formula for predicting is: vp x 1300 ÷ CF = ?

O2 formula for predicting is: vp x 1,300 = ? ÷ 50,000 = O2 drop (20.9% – O2 drop)

LEL formula for predicting is: (step #1) vp x 1300 = ? (step #2) CF x PLEL X 100 = ?

? ÷ ? = predicted LEL%

Which of the following is the correct predicted PID, O2 and LEL meter readings for this material?

VP = 15 mmHg, PID CF = 5, LEL CF = 2.1, PLEL = 2.2%
