ACM 150
Decontamination / Decommissioning Procedures
Purpose
To establish a safe procedure for decontamination and the eventual
decommissioning of the ACM 150 monitor at a customers' site.
Procedures
Wear appropriate Personal protective Equipment. Standard Nitrile gloves
are recommended.
1. Disconnect all gas sample lines from the fittings on the top of the ACM 150
monitor.
2. Allow the ACM 150 monitor to run in automatic sampling mode for 60 minutes
to purge any residual gases in the system. The automatic mode should include
the sample ports enabled during normal monitoring operation.
3. Shut off the CDA supply. The backup exhaust pump should automatically turn
on. Allow to run for 10 minutes.
4. Shut down the ACM 150 monitor by turning off the power at the power discon-
nect switch. Lockout and tagout the electrical supply at the facility connection.
5. Shut off the nitrogen supply. Verify that the pressure in both the CDA supply
and the nitrogen supply has been relieved. Disconnect both the CDA and nitro-
gen supply lines.
6. Remove and disconnect all electrical power and communications lines.
7. Remove and replace the sample filter located in the lower pump cabinet. The
panels of the lower cabinet are removable for access.
8. Inspect and clean the optics bench components, such as the sample cell, win-
dows and mirrors.
9. If moving the ACM 150 monitor, lock both the sliding optics bench drawer and
the pump assembly drawer by installing the appropriate sized screws through
the drawer plates and into the lock brackets.
10. Reinstall all outer panels removed during the cleaning procedure and close and
latch the outer doors.
11. If decommissioning, please recycle all applicable parts. These might include
the steel chassis, circuit boards, etc.
12. Please dispose the decontaminated unit according to all applicable local re-
quirements.
NOTE
The FTIR optics bench will absorb ambient moisture when not powered. Long
periods of storage will result in degraded performance of the optics bench and
may result in non-operation. Storage of an ACM 150 in high ambient humidity
environments is not recommended.
