Introduction
The SKC Hydrogen Cyanide (HCN) Passive Sampler, specifi ed in OSHA Method
1015, provides accurate sampling of hydrogen cyanide from 0.44 to 20 ppm for
either 15-minute or 8-hour samples. The uptake rate for the HCN Passive Sampler
is 28.4 ml/min. The sampler design allows the user to load 600 mg of soda lime
sorbent (supplied in a vial) into the sampler housing in the fi eld immediately before
sampling and transfer the sorbent from sampler to vial in the fi eld immediately
aft er sampling as specifi ed in the method. Samples are desorbed with water and
