Outbreaks Where Food Workers Have Been Implicated in the Spread of Foodborne Disease. Part 11. Use of Antiseptics and Sanitizers in Community Settings and Issues of Hand Hygiene Compliance in Health Care and Food Industries

By: Dr. Ewen Todd

Hand washing with soap is a practice that has long been recognized as a major barrier to the spread of disease in food production, preparation, and service and in health care settings, including hospitals, child care centers, and elder care facilities. Many of these settings present multiple opportunities for spread of pathogens within at-risk populations, and extra vigilance must be applied. Unfortunately, hand hygiene is not always carried out effectively, and both enteric and respiratory diseases are easily spread in these environments. Where water is limited or frequent hand hygiene is required on a daily basis, such as for many patients in hospitals and astronauts in space travel, instant sanitizers or sanitary wipes are thought to be an effective way of preventing contamination and spread of organisms among coworkers and others. Most concerns regarding compliance are associated with the health care field, but the food industry also must be considered.

Industry Standards

By: Dr. Irving Ojalvo

A standard can be defined as a document issued by a recognized agency, and dealing with design and/or safety requirements relating to a specific product or type of activity. Such agencies include the U.S. Occupational Safety and Health Administration (051-IA) and the American National Standards Institute (ANSI). OSHA standards are generally legally binding for an employer, while ANSI standards are generally of an advisory nature. The term "industry standard," however, is ordinarily taken to have a broader meaning, including formal standards as just defined, and also including designs and procedures not required in formal standards, though prevailing in a specific industry, and which represent generally accepted custom and practice.

Analysis and Testing in Accident Reconstruction

By: Dr. Irving Ojalvo

Persons with no training in engineering are generally unaware of the nature of engineering analysis, and so tend to assume that testing, as a means of determining the causation of accidents, is a dominant tool of the engineer. In the following examples, we shall undertake to explain the nature of engineering analysis, and to show that it is more basic than testing because testing without analysis is meaningless. Further, while analysis is always necessary in accident reconstruction, testing is only sometimes necessary.

Anti-Scale Valves

By: Dr.-Ing. Dirk A. Lindenbeck

In various industries there are valve applications where the standard valves used do not function satisfactorily. When scale is formed on the moving elements of ball valves or gate valves the consequence is either blocking of the valve movement or damage to the valve seats and consequent leaking through the valves

An Introduction To Corrosion

By: Earl Pye, PhD, PE

Suppose that you lose your pen. As a result you cannot write because you do not have a writing instrument that functions. That simple device, your pen, has a miraculous effect on your ability to perform. It is in this connection that we want to discuss the science and technology of corrosion
