Decontamination Procedures
The OSHA Bloodborne Pathogen Rule (29 CFR Part 1910.1030) requires the
decontamination of laboratory equipment prior to servicing or shipment:
• Decontaminate the instrument by performing the Auto-Clean cycle. This
cycle flushes all of the fluid pathways with reagents to purge any waste from
the fluid pathways. The Open Mode Sample Probe and the Closed Sample
Needle (CS Model) or Sample Loader Needle (SL Model) are automatically
rinsed after every cycle. The surfaces of the instrument should be wiped with
a nonabrasive detergent solution to remove any soiling, then wiped with a
tuberculocidal disinfectant, such as a 0.5% sodium hypochlorite solution.
To calculate the percent (%) sodium hypochlorite concentration desired see the
following formula:
A = Percent (%) of sodium hypochlorite solution desired
B = Percent (%) of sodium hypochlorite stock solution (as purchased)
X = Parts of water to be mixed with one part of the sodium hypochlorite stock
solution
Example:
If you need a 0.5% solution of sodium hypochlorite for a cleaning procedure, and
the label on the bottle of bleach states that it is 5.25% sodium hypochlorite, then:
Add 9.5 parts deionized water to 1 part bleach to obtain a 0.5% sodium
hypochlorite solution, or 9.5 mL of deionized water to 1.0 mL of bleach (5.25%
sodium hypochlorite) to obtain 10.5 mL of a 0.5% solution of sodium hypochlorite.
If the instrument is to be shipped, it must be decontaminated prior to shipment. This
is accomplished by pressing the
[PREPARE FOR SHIPPING]
key in the
SPECIAL
PROTOCOLS
menu. Instructions for this procedure are given in section
Preparation for Shipping or Extended Period of Non-Use.
