SKC 590-400 Hydrogen Cyanide Passive Sampler - Manual (Page 2)

Sampling
Remove sampler housing and vial of sorbent from
resealable aluminized pouch.
Write pertinent information, including
Sample ID#, on the lines provided on the
pouch label and the sampler housing.
Note: OSHA Method 1015 specifies that
the sample site temperature and uncorrected
atmospheric pressure be recorded.
Soda lime sorbent is very caustic. Wear gloves
when handling sampler and vial to avoid skin
contact with sorbent.
Perform this step immediately before sampling
or on the day of use. In a clean environment,
free of hydrogen cyanide and hydrogen sulfi de
(interferent), remove plug from vial adapter on
back of sampler housing (side without holes).
Remove cap from sorbent vial. Immediately
screw open end of vial counterclockwise into
the vial adapter until secure (see inset 3A). Rotate
entire assembly until sorbent is draining from
vial to sampler (Figure 3). Tap vial lightly before
unscrewing and removing it from the adapter.
Immediately replace plug on vial adapter. Store
sorbent vial and cap in aluminized pouch.
Record start time on the sampler label. Remove
cover from face of sampler housing (side with
holes) immediately before sampling. Store cover
for reuse.
The sampler begins sampling immediately when cover
is removed.
Clip sampler to a worker’s collar near the
breathing zone. The diff usion holes must face
outward. The front of the sampler must not be
covered by clothing or obstructed in any way
during the sampling period.
Do not cover sampler with clothing.
Aft er the desired sampling period, immediately
unclip sampler from worker’s clothing. Seal
sampler with cover immediately.
