Water, Steam and Air Sources 1600 South Jackson Street Seattle, Washington 98144 Phone 206‐323‐3540 Fax 206‐323‐3543 SETTING THE STANDARD IN SEAFOOD SAFETY WATER, STEAM AND AIR SOURCES Technical Bulletin SOP-09 Processors are required by regulation to ensure the safety of water and air sources used for food processing. All utilities to and within the production and storage areas shall be designed, constructed, maintained and monitored to effectively control the risk of product contamination. All water used for the preparation of product, or for equipment or plant cleaning shall be supplied in sufficient quantity, and be potable or pose no risk of contamination. The microbiological and chemical quality of water, steam, ice, air, compressed air or other gases that do not constitute an ingredient but come in direct contact with food or packaging shall be regularly monitored at a frequency based on risk assessment that ensures their safe and suitable use in food manufacturing. Water: Municipal water supplies are subject to local requirements for sanitary and potable conditions. The water supplied by municipalities is required to be potable, i.e. safe for direct consumption. Utilities are required to test their water supplies against chemical and microbiological criteria to ensure potability. Test results from the utility companies are generally available upon request. It is advisable to obtain these results periodically as a verification procedure. Utilities are also required to provide public notice to their customers when water is not of required potability. In addition to the utility company requirements, food manufacturers in the United States are required to comply with Good Manufacturing Procedures (GMPs in 21 CFR 110) and Sanitation Standard Operating Procedures (SSOPs in 21 CFR 123) that provide additional assurance of quality and safety of water, ice, and steam. The testing regimen, advisory systems, and regulatory requirements should all be considered when analyzing the risk of public safety arising from the manufacturer’s use of the water supply. Regulatory requirements also apply to private water sources. These prerequisites would appear to minimize the risk for compliant water sources used at a manufacturing facility for domestic, processing, steam, and ice making purposes. Manufacturers of products that will be distributed internationally should also ascribe to the Codex Code of Practice General Principles of Food Hygiene that states: An adequate supply of potable water with appropriate facilities for its storage, distribution and temperature control, should be available whenever necessary to ensure the safety and suitability of food. Potable water should be as specified in the latest edition of WHO Guidelines for Drinking Water Quality, or water of a higher standard. Non-potable water (for use in, for example, fire control, steam production, refrigeration and other similar purposes where it would not contaminate food), shall have a separate system. Non-potable water systems shall be identified and shall not connect with, or allow reflux into, potable water systems. Revision Date: 6-10-08 Supersedes: Technical Bulletin SOP-09, 4-16-08 www.spa‐food.org 1 Cont. Water, Steam and Air Sources Steam: When steam comes in direct contact with food or direct food contact packaging, it is important to ensure that all constituents of the steam are safe and suitable for such use. In addition to a potable water source, chemicals used for boiler treatment should be specifically authorized for use for direct food contact application when applicable. For example steam used headspace injection to create vacuum in canned products. Authorization may be in the form of: • Documentation verifying the chemicals have a USDA ID number of G-6, which would be a food contact approved chemical. • Compliance with US regulation 21 CFR 173.310 - Boiler water additives. • Other evidence of the safety and legality of the chemicals used for boiler treatment. Processors should also have a Sanitation Standard Operating Procedure (SSOP) in place that verifies appropriate application of the approved treatment chemical. Air: Food manufacturers that are regulated by the US Food and Drug Administration must comply with GMPs, including those in 21 CFR 110.40(g) as follows: (g) Compressed air or other gases mechanically introduced into food or used to clean food-contact surfaces or equipment shall be treated in such a way that food is not contaminated with unlawful indirect food additives. SSOPs in 21 CFR 123 provide additional requirements that would ensure the safety of the air supply used by: (5) Protection of food, food packaging material, and food contact surfaces from adulteration with lubricants, fuel, pesticides, cleaning compounds, sanitizing agents, condensate, and other chemical, physical, and biological contaminants; Regulations in 21 CFR 123 include requirements for monitoring and documenting SSOPs. Given the numerous regulatory requirements for the control of water, steam, ice, and air in a food processing facility, there would be no significant risk to product safety or quality for compliant companies. Companies should use GMP and SSOP monitoring records, product spec sheets (for boiler chemicals), and utility records (for public sources) as affirmative evidence of compliance. 2 .

Preface to the Second Edition The international research regarding the thermophysical properties of water and steam has been coordinated by the International Association for the Properties of Water and Steam (IAPWS). IAPWS is responsible for the international standards for thermophysical properties. These standards and recommendations are given in the form of releases, guidelines, and advisory notes. One of the most important standards in this sense is the formulation for the thermodynamic properties of water and steam for industrial use. In 1997, IAPWS adopted the “IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam” for industrial use, called IAPWS-IF97 for short. The formulation IAPWS-IF97 replaced the previous industrial formulation IFC-67 published in 1967.

    Manual Epilepsy Warning Some people may experience photosensitive epileptic seizures or a loss of consciousness when viewing certain visual stimuli, such as flashing lights or patterns, in everyday life. Such individuals are at risk of experiencing seizures while watching television or playing video games. This can happen even to individuals with no history of related health conditions or signs of epilepsy. The following symptoms are characteristic of photosensitive seizures: blurred vision, eye or facial twitching, trembling arms or legs, disorientation, confusion or momentary loss of balance. During a photosensitive seizure, loss of consciousness and convulsions may cause serious accidents, as these symptoms are often accompanied by a fall. If you notice any of the above symptoms, stop playing immediately. It is strongly recommended that parents supervise their children while playing video games, as children and adolescents are often more prone to photosensitive seizures than adults. If any such symptoms occur, STOP PLAYING IMMEDIATELY AND SEEK MEDICAL ADVICE. Parents and guardians should keep children in sight and ask them if they have ever experienced one or more of the above symptoms.

  • A Partial Glossary of Spanish Geological Terms Exclusive of Most Cognates
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY A Partial Glossary of Spanish Geological Terms Exclusive of Most Cognates by Keith R. Long Open-File Report 91-0579 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government. 1991 Preface In recent years, almost all countries in Latin America have adopted democratic political systems and liberal economic policies. The resulting favorable investment climate has spurred a new wave of North American investment in Latin American mineral resources and has improved cooperation between geoscience organizations on both continents. The U.S. Geological Survey (USGS) has responded to the new situation through cooperative mineral resource investigations with a number of countries in Latin America. These activities are now being coordinated by the USGS's Center for Inter-American Mineral Resource Investigations (CIMRI), recently established in Tucson, Arizona. In the course of CIMRI's work, we have found a need for a compilation of Spanish geological and mining terminology that goes beyond the few Spanish-English geological dictionaries available. Even geologists who are fluent in Spanish often encounter local terminology oijerga that is unfamiliar. These terms, which have grown out of five centuries of mining tradition in Latin America, and frequently draw on native languages, usually cannot be found in standard dictionaries. There are, of course, many geological terms which can be recognized even by geologists who speak little or no Spanish.

  • Improve Your Boiler's Combustion Efficiency
    ADVANCED MANUFACTURING OFFICE Energy Tips: STEAM Steam Tip Sheet #4 Improve Your Boiler’s Combustion Efficiency Suggested Actions Boilers often operate at excess air Combustion Efficiency levels higher than the optimum. Periodically monitor flue gas Operating your boiler with an optimum amount of excess air will minimize heat composition and tune your boilers loss up the stack and improve combustion efficiency. Combustion efficiency to maintain excess air at optimum is a measure of how effectively the heat content of a fuel is transferred into levels. usable heat. The stack temperature and flue gas oxygen (or carbon dioxide) concentrations are primary indicators of combustion efficiency. Consider online monitoring of flue gas oxygen level to quickly identify Given complete mixing, a precise or stoichiometric amount of air is required energy loss trends that can provide to completely react with a given quantity of fuel. In practice, combustion early warning of control failures conditions are never ideal, and additional or “excess” air must be supplied to and allow data to drive your completely burn the fuel. decision making. The correct amount of excess air is determined from analyzing flue gas oxygen or carbon dioxide concentrations. Inadequate excess air results in unburned combustibles (fuel, soot, smoke, and carbon monoxide), while too much results in heat lost due to the increased flue gas flow—thus lowering the overall boiler fuel-to-steam efficiency. The table relates stack readings to boiler performance.
