NOTE: The pickup points located on the floor in the above illustration are examples for
refrigerants which are heavier than air. Placement of pickup points should be determined
based on characteristics of the gas being monitored and ambient conditions of the sampling
area. (Air=28.9 g/mole, CO
2
=44.0 g/mole, NH
3
=17.0 g/mole, and halogens = 100+ g/mole.)
