MSA is issuing this User Safety Notice to inform you of action required for a single production lot of Four Gas Calibration Cylinders (58L). The manufacturer of the cylinders has informed MSA that the torque used to secure the valve to MSA Four Gas Calibration Cylinders in lot 239511 may have been below specification for some cylinders in the lot.

When disconnecting the calibration cylinder from an accessory, such as the Galaxy® GX2 Automated Test System (GX2), there is potential that the cylinder will unthread from the valve. If this happens, the pressure in the cylinder can cause the cylinder to become a projectile.

MSA has not received any reports of injuries associated with this condition. However, we are requesting that you perform the actions outlined in this notice.

The composition and quality of the calibration gas in the cylinders is unaffected by this condition.
 

Potentially affected cylinders were sold as part number 10045035. In Brazil, potentially affected 10045035 cylinders were also sold as part of calibration kit part numbers 10195003, 10197496, 10214653 and 219445.

Identifying Potentially Affected Product
Review the cylinder labels for the part number and lot number (See Figure 1 in attached user notice). Alternately, if the cylinder is installed in a GX2 with RFID capability, you can use the test system interface to view the part number and lot number (See Figure 2 in attached user notice). Do not loosen a cylinder installed in a GX2 in an attempt to read the label.

Your cylinder is impacted if the lot number is 239511 AND cylinder part number is 10045035.

Addressing Potentially Affected MSA Four Gas Calibration Cylinders (58L)
We recognize that this is an inconvenience and in an effort to minimize any disruption, we pledge to take any replacement actions as expeditiously as possible.

If you are in possession of MSA Four Gas Calibration Cylinders (58L) that meet the criteria for affected product above, follow the instructions below to remove the cylinder from service and dispose of them per local regulations. MSA will replace your cylinders free of charge.

To receive replacement cylinders, please complete the enclosed MSA Four Gas Calibration Cylinder (58L) Replacement Order Form and e-mail it to MSA Customer Service at the appropriate e-mail address below. Please note that you must provide a photo of the label showing the cylinder number, part number and lot number for each replacement cylinder that you request.

Removing Cylinders from Service
SHOULD YOU HAVE ANY QUESTIONS OR REQUIRE SUPPORT FOR THESE OPTIONS PLEASE CONTACT MSA CUSTOMER SERVICE AT THE CONTACT INFORMATION BELOW.

1. If the cylinder is NOT installed in a GX2:
   a. If the cylinder is attached to an MSA fixed flow regulator, use the regulator to vent the cylinder to zero pressure. Vent the cylinder contents in a well-ventilated area outdoors as per the Safety Data Sheet – attached to the User Safety Notice. Do not remove the regulator until the cylinder is vented to zero pressure. Once the cylinder is vented to zero pressure, remove the regulator from the cylinder and dispose of the cylinder in accordance with local regulations.
   b. If the cylinder is not attached to an MSA regulator, attach an MSA fixed flow regulator and follow the instructions in figure 1a in attached user notice. If you do not have an MSA fixed flow regulator, contact MSA customer service to request one. While awaiting delivery of the MSA fixed flow regulator, put controls in place to ensure that the cylinder is not used.
   c. If the cylinder is attached to an MSA demand flow regulator for pumped instruments such as the Altair 5X, vent the cylinder using an MSA Altair Pump Probe (Part Number 10152669). Vent the cylinder contents in a well-ventilated area outdoors as per the Safety Data Sheet – attached to the User Safety Notice. If you do not have an MSA Altair Pump Probe, contact MSA Customer Service. While awaiting delivery of the MSA Altair Pump Probe, put controls in place to ensure that the cylinder is not used.
   i. Prepare the pump probe per the steps in Figure 4 in attached User Safety Notice.
   ii. Connect the pump probe to the demand flow regulator with 1/8 inch inner diameter tubing.
   iii. Turn on the pump probe (green light indicator will be on).
   iv. Once the cylinder is empty, the pump probe will beep and the light indicator will turn solid red. Remove the regulator from the cylinder and dispose of the cylinder in accordance with local regulations.
   
   
2. If the cylinder is installed in a GX2, follow the instructions below.
   a. Vent the cylinder while it is in the GX2 using an MSA Altair Pump Probe (Part Number 10152669). Vent the cylinder contents in a well-ventilated area outdoors as per the Safety Data Sheet – attached to the User Safety Notice. If you do not have an MSA Altair Pump Probe, contact MSA Customer Service. While awaiting delivery of the MSA Altair Pump Probe, put controls in place to ensure that the cylinder is not removed from the GX2.
   i. If the GX2 is mounted to a wall, follow the steps in Figure 3 in attached user notice to remove it from the wall. Multiple people are required during this effort to support the GX2 while it is removed from the wall.
   ii. Remove the cylinder holder with the affected cylinder from the cylinder bank per the steps in Figure 4 in attached User Safety Notice.
   iii. Prepare the pump probe per the steps in Figure 5 in attached User Safety Notice.
   iv. Connect the pump probe to the cylinder holder gas out port (see Figure 6 in attached User Safety Notice).
   v. Turn on the pump probe (green light indicator will be on).
   vi. Once the cylinder is empty, the pump probe will beep and the light indicator will turn solid red. Remove the cylinder from the cylinder holder and dispose of the cylinder in accordance with local regulations.
