Food Irradiation

Contributed by
Stanford University Radiation Safety Officer, Lance Phillips

Recently you may have seen some news reports on the irradiation of food products. According to the Center for Disease Control (CDC), food irradiation is a promising new food safety technology that can eliminate disease-causing germs from foods. Ionizing radiation can kill bacteria and parasites that would otherwise cause illnesses from the food or lead to rapid food spoilage. Food irradiation is currently used in France, the Netherlands, Portugal, Israel, Thailand, Russia, China and South Africa. Irradiation of medical devices is currently used in this country to sterilize them prior to surgery or implantation. The irradiation effects on the food have been studied extensively. These studies show that when irradiation is used as approved:

  • disease-causing germs are reduced or eliminated
  • the food does not become radioactive
  • dangerous substances do not appear in the foods
  • the nutritional value of the food is essentially unchanged

For more information on food irradiation you may wish to examine the CDC website, or view the news reports prepared by Kansas State University on their website (link currently unavailable), or review the information provided on Iowa State University's website

Fire Alarm and Sprinkler Testing in University Buildings

Contributed by
Fire Protection Services Supervisor, Arleen Muscie

Do you ever wonder why you see Fire Protection Technicians in your building several times a year? Could it be that we enjoy Stanford faculty, staff and students so much, that we desire to visit on a regular basis? Well, although that may be true, the main reason is to provide the Preventive Maintenance (PM) testing of Fire Alarms, Fire Sprinklers, and Fire Extinguisher Equipment.

After several years of providing service to the Campus we have worked out an arrangement that satisfies our customers as well as allows us the flexibility to complete our preventive maintenance work. Fire Alarm technicians test audible alarms (horns and strobe devices) starting 6:30 a.m. Monday thru Friday and complete the test prior to 7:30 a.m. After 7:30 a.m. the remaining fire alarm devices are tested conducting a silent test. All buildings that have preventive maintenance testing have signage provided to the Building Managers for their own internal distribution.

Our Housing Customers have agreed to a 10:00 a.m. start time for audible testing.
This timeframe provides an opportunity to work within the building without disturbing the students as they prepare for a busy day. There are two audible tests for Housing buildings. One of the tests is conducted during the Annual Evacuation Drill regularly scheduled during the first week of October to coincide with Fire Prevention Week. The second audible test is conducted during the routinely scheduled Preventive Maintenance in the spring months of the year.

The fire sprinkler testing is primarily a silent test within the interior of the building. There is an audible horn on the outside of the building that coincides with the water flow test.

We are pleased to have worked out arrangements suitable for our customers' varying needs with minimal interruption to their residential, class, and work schedules. Please review our Fire Protection Services web page or call Arlene Musci at 723-9754 if you need additional information about our services.


Air District Urges Prudent Use of Wood Burning Fireplaces

Contributed by
Environmental Specialist, Heather Perry

The Bay Area Air Quality Management District (BAAQMD) is urging the public to help reduce nighttime air pollution by cutting back the use of wood burning fireplaces. Wood smoke is a significant source of carbon monoxide, nitrogen dioxide, volatile organic compounds and inhalable particulate matter. These are all pollutants regulated by state and federal regulations because of their known adverse health effects.

BAAQMD issues an advisory when unhealthy air predictions are made for a given evening. BAAQMD issues these "Don't Light Tonight" warnings via email. If you would like to receive these advisories, you can register to receive them at THE 2002 SPARE THE AIR PROGRAM REGISTRATION.
For more information on the harmful effects of wood smoke, read the WOODBURNING HANDBOOK.

If you have questions, you may contact Heather Perry at extension 3-1308.

Laboratory Chemical Waste Cleanout Guidelines and Request Form

Contributed by
Radioactive Waste Technician, LeAnne Amoroso

The Chemical Waste Management Team has developed and placed on our web pages newly revised guidelines and a web interactive request form for Laboratory Chemical Waste Cleanouts. This was developed to clarify the procedures of this service and make it easier for campus researchers to keep their laboratories in compliance and their workplaces safer. The guidelines should prove helpful to laboratories in need of disposing of a large number of chemicals at one time. The request for a lab clean out will eliminate filling out a large number of hazardous waste tags. The request form only requires a general description of the chemicals, eliminating the need to write every chemical name down. Sending the form electronically will assure the form gets to the right place and the labs with get a much faster reply.

If you have any questions about this service, please contact LeAnne Amoroso by email or phone at 5-1408.

New E-MSDS Service at Stanford University

Contributed by
Industrial Hygienist, Yong Kim

Starting February 2003, Stanford University has introduced a new electronic Material Safety Data Sheet service. This change in MSDS service delivers additional e-MSDS retrieval functionality for campus users which were previously unavailable:

  • Advanced MSDS search and sort functionality;

    The MSDS search tool allows you to list and sort MSDSs by chemical name, manufacturer, CAS Number, and/or product ingredient.

  • Availability of numerous MSDS collections;

    Totaling 780,000 MSDSs, both generic and manufacturer-specific MSDSs are available to search. For details on specific collections available, see the MSDS Sources page.

  • Ability to email MSDSs to campus colleagues;

    As users view an MSDS online, you are given the option of emailing the selected MSDS to other Stanford University personnel.

In addition to added functionality, this shift in MSDS services provides a much-appreciated cost-savings to the University research community. To read all about the new features and user tips, see the Help Topics page. For any further questions, please feel free to contact EH&S- Hazardous Materials Management Program at x5-1472.

E-mail us with your questions, thoughts and suggestions or if you would like to be added to our mailing list.
