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

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.

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.

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.

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.
