Steam Quality Test

Steam Quality (Pure Steam) for Pharmaceutical use shall be ensured by-

1. Test for Level Non- Condensable Gases (Oxygen, Carbon di-oxide, Nitrogen, Ammonia, and some halogenated hydrocarbon gases etc).

Limit= Should not be more than 3.5 %.

2. Dryness Value Test or Moisture Level in Steam

0.90- For porous Loads
0.95- For Metal Loads

Excess moisture in steam will cause dumping of Loads. 
Less moisture cause raising of superheat value. 

Value for porous Load=
Value for Non-porous Load=
3. Super heat value of steam at expansion tube.
25 degree Celsius

NVPC

NVPC Online NVPC: Make= Beckman; Model= Met one 6015P; Capacity= 1CFM SOFTWARE= EnVigil Critical alarm: Critical alarms are those alarms when generated indicate excursion which may impact the product quality. Alarm generated in location where the NVPC probe is in close proximity to the product/ sterile container closure/ product contact path. Location for critical alarms includes grade A location - Filling station, Bunging station, Bunging Hopper station, Portable cart, IOS station, AGV station, Near lyophilizer door open, between lyophilizers (near Lyo) and Lyo LAF (rigid barrier transfer conveyor). Critical alarms include the following- 1.     Particle count excursion beyond the acceptance criteria at a particular location. 2.     Sensor Failure, Counter Flow Failure, ERROR or SKIPPED message. Ensure and verify the status of counter flow to meet the below set limit- Target Counter flow – 1.0 CFM. Minimum counter flow: ...

Audit and compliance

Audit readiness Reference https://www.fdanews.com/ext/resources/files/The_Food_And_Drug_Letter/2013/Inspection-Readiness-ExecSeries.pdf https://ispe.org/initiatives/regulatory-resources/gmp/audit-checklist# Before start of audit we need to review past audits and note indication of possible problem areas and items, if any ensure that were identified for corrective actions in a previous audit. If not aware about facility learn what products being produced and how it is organised with personal and function. To have systematic audit checklist to be prepared and alongwith notebook it needs to be utilised (notebook required to make detailed entries while audit and checklist is to guide auditor). Atleast three production batches to be selected For thorough analysis to include- a) Traceability of all components or materials used in that batch. b) Documentations of raw materials or components, inprocess and finished goods testing for subject product batches. c) Warehousing and distribution reco...
