Filling Isolator Glove and Pressure Check

The filling isolator glove and the differential on the site's gauge are the evidence the barrier is intact. The technician writes the as-found reading and compares it with the last one on the asset. Do not change a pressure cascade or a fill parameter. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. Inspect glove ports for holes, cracks and the correct installed glove
  2. Record the isolator differential at the gauge the site uses
  3. Confirm the transfer-port seals and the HEPA differential
  4. Do not change a pressure cascade or a fill parameter from this work order
  5. Take the isolator out of use if a glove fails

Why This PM Exists

The filling isolator glove and the differential on the site's gauge are the evidence the barrier is intact. The technician writes the as-found reading and compares it with the last one on the asset. Do not change a pressure cascade or a fill parameter. Anything past that line belongs to the site's own procedure, the OEM manual, or a permit. This is the inspection ChatterFix schedules. It is not itself permission to go further.

What Skipping It Looks Like

A pinhole glove stays on because the differential still reads and the fill is mid-lot. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not change a pressure cascade or a fill parameter.

Setting the interval

Weekly. A failed glove takes the isolator out of use. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.

Common Questions

How often should this PM run?
Weekly. Weekly. A failed glove takes the isolator out of use. An as-found reading outside the limit the site already published is a finding. It does not become a new setpoint on this work order.
How long does it take?
Budget about 1.0 hour for a technician working to the standard procedure. ChatterFix uses that estimate for capacity planning, then learns your plant's actual time from completed work orders.
What happens if we skip it?
A pinhole glove stays on because the differential still reads and the fill is mid-lot. The round still closes, the number never lands on the asset, and the next person inherits a guess. Do not change a pressure cascade or a fill parameter.
