                      EPA Risk Management Program 
                           Executive Summary 
1.   Accidental Release Prevention and Emergency Response Polices 
Heinz Frozen Food Company s (HFFC) manufacturing sites comply with applicable federal, state 
and local regulations.  As with all HFFC manufacturing locations, this food processing facility has 
a formal worker safety program.  All employees are informed of hazards in the workplace.  
Employees who work with potentially hazardous substances receive proper training in the 
handling of those substances.  This facility has procedures in place to safely remove employees 
from areas in the unlikely event that a hazardous substance release were to occur, and to put in 
place emergency notification and response procedures. 
2.   Facility and Regulated Substances 
This Heinz Frozen Food Company food processing facility is located at 1301 S.W. Oberlin Road, 
Massillon, Ohio.  Frozen prepared foods are produced at this location.  Food ingredients are 
received, blended, mixed, cooked, assembled, frozen and packaged.  The regulated substance at 
this facility, anhydrous ammonia, is used in a closed-loop refrigeration system for product cooling 
and freezing. 
3.   Worst-Case and Alternate-Case Release Scenarios 
The worst-case scenario consists of the release of ammonia from the largest vessel over a period 
of ten minutes.  The maximum quantity of ammonia in the vessel is limited to 80-percent of the 
total volume of 32,500 pounds via written administrative controls, resulting in a release of 
approximately 26,000 pounds of ammonia.  There are off-site impacts under this worst-case 
The alternate-case scenario consists of the release of ammonia vapor from a safety relief valve due 
to an overpressure cond 
ition in a vessel located in the facility s machine room.  The relief valve is 
designed to vent ammonia to the atmosphere when its pressure rating is exceeded, preventing 
potential damage to other components in the refrigeration system.  The scenario results in a 75 
pound ammonia release over a period of 6 minutes.  There are no off-site impacts under the 
alternate-case scenario. 
4.   General Accidental Release Prevention Program and Ammonia Specific Prevention 
All Heinz Frozen Food Company manufacturing locations comply with the OSHA Process Safety 
Management for Highly Hazardous Chemicals (PSM) standard relative to anhydrous ammonia.  
Therefore, this facility has programs to ensure proper operation and maintenance of the ammonia   
refrigeration system.  Further, refrigeration system operators have been trained and are 
knowledgeable in the safe operation of the refrigeration system. 
The ammonia refrigeration system at this facility has been designed and constructed using good 
ering practices and to conform to industry standards.  The system includes ammonia 
detection devices, an emergency shutdown switch located outside the main mechanical room, 
high- and low-level switches in pressure vessels, and safety relief valves to avert serious system 
overpressure.  Periodic maintenance on the refrigeration system is ensured via the use of a 
computerized maintenance management system.  Annual physical system audits are performed by 
an external refrigeration contractor to ensure system integrity.  
5.   Five Year Accident History 
During the past five years this facility has had no releases that resulted in deaths, injuries, or 
significant property damage on site or known offsite deaths, injuries, evacuations, sheltering in 
place, property damage, or environmental damage. 
6.   Emergency Response Program 
This food processing facility has procedures in place to respond to the release of a hazardous 
substance.  Employees are trainded to evacuate their respective areas 
in accordance with OSHA 
1910.38(a).  Coordination with the local fire department and LEPC is initiated during an 
emergency situation.
