                         PERFORMANCE FOOD GROUP 
                         RISK MANAGEMENT PROGRAM 
                                                    EXECUTIVE SUMMARY 
1.  General accidental release and prevention policy of Performance Food Group. 
In this frozen food distribution center we utilize anhydrous ammonia as a refrigerant.  Anhydrous 
ammonia is considered hazardous by the Environmental Protection Agency. The same properties 
that make ammonia a valuable refrigerant also makes it necessary to observe certain safety 
precautions during it's use to prevent human exposure, reduce the threat to our workers personal 
health, the surrounding community and the environment.  It is our policy to adhere to all 
applicable federal and state regulations.  Safety depends directly on our proper handling of 
ammonia combined with the safety devices that are incorporated in our facility and the safe 
handling procedures that our personnel are trained in. 
2.  Stationary source and regulated su 
bstance handled. 
Performance Food Group, 4041 N.E. 54th Avenue, Gainesville, Florida is responsible for the 
storage and distribution of various frozen food products.  There are approximately 75 employees 
at this facility which includes hourly and salary personnel.  This distribution facility receives and 
prepares shipment of frozen food via tractor trailers approximately 20 hours a day, seven days a 
Performance Food Group is located in an industrial park approximately 3 miles north east of the 
city of Gainesville, Florida.  In addition to our distribution facility the industrial park also houses 
other manufacturing or business facilities.   
The potentially hazardous chemical used at the Performance Food Group facility is 
ANHYDROUS AMMONIA.  The dominant characteristic of ammonia vapor is it's pungent, 
distinct odor.  Persons exposed to ammonia will not voluntarily stay in areas of even small 
concentrations, although these levels would not result in any health risks.  
Risks f 
rom accidental exposure to ammonia in a vapor state are irritations to the eyes, nose and 
throat. The extent of irritation depends on the exposure amount and length of time exposed.    
Ammonia is classified non-flammable by the Department of Transportation.  Ammonia will burn, 
but only in a very narrow, high concentration level when accompanied with a constant ignition 
The normal operating level of ammonia that is used/stored at the Performance Food Group facility 
is 12,000  pounds. Anhydrous ammonia is used as the chemical in the refrigeration process. The 
possible hazards that could lead to an accidental release include, but are not limited to, equipment 
failure, damage to piping, damage to equipment, human error, etc.  
3. Worst case release scenario and alternate release scenarios including administrative and 
engineering controls to limit/ prevent the release. 
Worst case scenario depicts continuous source leak from the High Pressure Receiver (HPR) 
located inside the 
machine room.  This vessels normal operating level is 4,145 pounds of liquid 
ammonia,  approximately 50% of it's total capacity. Although it's maximum capacity is 8,290 
pounds, this exceeds company policy  and engineering controls of only allowing an 80% level in 
the vessel at any time.  
    Worst case release scenario criteria for Performance Food Group facility: 
    Ammonia Quantity:                  4,145 pounds 
    Rate of Release:                   415 lbs / min. (10 min. release) 
    LOC (Level of Concern):            200 ppm  (EPA ERPG-2)   
    Physical State:                    Gas and/or Liquid 
          Type of Area:                     Urban 
    Wind Speed:                        1.5 m/sec 
    Distance to Endpoint                    2.2 miles 
Alternate release scenario is represented by the release of ammonia vapor from a safety relief 
valve (SRV) due to an over-pressurization condition on a vertical vessel located within the facility 
machine room.  SRV wou 
ld be performing exactly as it is designed to do during an over- 
pressurization condition. 
    Alternate case release scenario criteria for Performance Food Group facility: 
    Ammonia Quantity:                  103 pounds 
    Rate of Release:                         23 pounds/min. (6 min. release) 
    Wind Speed:                        3.0 m/sec. 
    Distance to Endpoint:                   211 yards 
    The following administrative and engineering controls are in place at the 
Performance Food Group to limit the release possibilities, or distance of release for the 
reported scenarios. 
    *  Electronic ammonia detection in machine room and distribution areas.  Alarms tie in to 
the maintenance system control computer.  Computer system activates a local audible alarm 
indicating an abnormal operating status.  (Future upgrade will incorporate computer equipment 
alarms into a commercially operated alarm company.) 
    *  Periodic Maintenance Program is esta 
blished within the maintenance department to 
ensure the refrigeration system and it's components are kept in optimum operating status. 
    *  Emergency shut down procedures are in place and periodic training is held to activate 
the shut down system during an actual emergency. 
    *  High and low level switches are configured to all pressure vessels which shut down 
compressor operation during an abnormal level condition. 
    *  Safety Relief Valves are configured to all pressure vessels, condensers and compressor 
oil separators to eliminate over pressurization conditions in those associated pieces of equipment. 
4.  Five-year accident history. 
The Performance Food Group distribution facility has zero accidental releases to report. The 
ammonia refrigeration system was installed during the first half of 1998. 
5.   Emergency Response Program 
The purpose of the Performance Food Group Emergency Action Plan is to: 
    1.   Minimize exposure to our employees and the surrounding co 
mmunity in the event of a 
    hazardous material release or spill. 
    2.  Assure the safe emergency evacuation of the plant in the instance that it is required. 
    3.  Provide for prompt medical attention to any employees who become seriously injured 
    or ill at work. 
    4.  Manage an emergency response system and coordinate response of the internal and 
    external resources required to provide efficient and effective response to any type of 
    emergency that may occur at our facility. 
This EAP currently meets requirements as set forth in OSHA 29 CFR 1910.38, Employee 
Emergency Plans and Fire Prevention Plans.  We coordinated this plan with a Gainesville Fire 
Department representative during their visit to the plant
