ACM 150
Chemical safety
Located within the sample gas cell are two windows made of a potentially toxic
material called ZnSe (zinc Selenide). An MSDS for ZnSe is included in Appendix B.
Special attention to the MSDS should be given and appropriate precautions taken by
the user when performing maintenance on the gas cell
The majority of the time the ACM 150 monitor is operating, it is sampling ambient
air without toxics. In the event of a toxic gas release at one of the sample points for
the monitor, small amounts of toxic gas and/or residue may be trapped inside the
sample tubing, filters and pumps inside the monitor. During normal operation these
trapped gases will be purged through the monitor and pose little risk as they are
diluted before being sent out the exhaust.
However, during maintenance procedures that involve disassembly of these
components, care is advised to make sure that if the monitor has experienced a
toxic gas release, appropriate protective equipment is used to ensure user safety. It
is also the responsibility of the user to dispose of all contaminated parts and service
items such as filters and wipes per local rules and procedures. Refer to section 9 for
further details.
Process compatibility
All components are compatible with the materials in the ACM 150 monitor. All
sample-wetted materials are PFA, PTFE, PVC, acrylic, stainless steel, anodized
aluminum or glass. The normal operating pressure of the sample-wetted components
is a vacuum, however most of these materials are designed to withstand a maximum
pressure of 80 psi at room temperature.
Some of the flexible lines contain high pressures. The burst pressure of the internal
flexible tubing as originally supplied is dependant on its sizes:
• 1/4" (heavy wall) has a burst pressure of 270 psig at 70°F
• 3/8" (heavy wall) has a burst pressure of 230 psig at 70°F
• 1/2" (heavy wall) has a burst pressure of 155 psig at 70°F
To protect against rupture from an abnormal pressure condition, a pressure relief
valve is provided. Do not remove or modify this pressure relief valve.
CAUTION
Failure to operate the ACM 150 monitor within the pressure and temperature
limits specified can cause leaks. Only operate the ACM 150 monitor within the
pressure and temperature limits specified.
