Failure to have accurate P&IDs could result in human error during operations and maintenance and employees not being able to identify or locate equipment in the event of an emergency resulting in exposure to anhydrous ammonia vapors and liquid. b. Machine Room - On or about July 13, 2022, the screw compressor (RC-6) pressure gauge was not shown on P&ID R2.2. Failure to have accurate P&IDs could result in human error during operations and maintenance and employees not being able to identify or locate equipment in the event of an emergency resulting in exposure to anhydrous ammonia vapors and liquid. c. Machine Room - On or about July 13, 2022, the High/Low Temp glycol chiller (GC-4) is labeled as HTLT-GC2 instead of (GC-4) in the field on P&ID R2.3. Failure to have accurate P&IDs could result in human error during operations and maintenance and employees not being able to find specific locations in the event of an emergency resulting in exposure to anhydrous ammonia vapors and liquid. d. Lower Machine Room - On or about July 13, 2022, the AFP glycol chiller (GC-2) is mislabeled as LTST1 in the field on P&ID R2.4. Failure to have accurate P&IDs could result in human error during operations and maintenance and employees not being able to find specific locations in the event of an emergency resulting in exposure to exposure to anhydrous ammonia vapors and liquid. e. Outside the AFP Cooler - On or about July 13, 2022, the AU-R and AU-L had pressure indicator gauges on them however it does not reflect these gauges near Hause HSB on P&ID 2.5, failure to have correct P&ID's could result in employees not being able to find specific locations in the event of an emergency resulting in exposure to anhydrous ammonia vapors and liquid. Abatement certification required within 10 days after abatement date. The certification shall include a statement that abatement is complete, date and method of abatement, and states employees and their representatives were informed of this abatement.
