Carbon Monoxide Risks at Home

Contributed by Asst. Univ. Fire Marshal, Alison Pena

Carbon monoxide (CO) is an invisible, odorless, colorless gas created when fuels (such as gasoline, wood, coal, natural gas, propane, oil and methane) burn incompletely. In the home, heating and cooking equipment that burn fuel are possible sources of carbon monoxide. Vehicles or generators running in an attached garage can also produce dangerous levels of CO. However we can protect ourselves against CO poisoning by properly installing, using, venting and maintaining heating and cooking equipment. We can also install CO alarms inside our homes and practice caution when running vehicles and generators inside attached garages.

Mild effects of carbon monoxide exposure feel like the flu while severe effects include difficulty breathing and even death. This occurs as carbon monoxide replaces oxygen in the bloodstream, which eventually leads to suffocation. Just how sick people get from CO exposure varies, depending on the concentration and length of exposure. As with anything harmful that is inhaled the severity of harm depends on the dose. The same dose of CO can be received through a long exposure to a low concentration or a brief exposure to a high concentration. Given time, the body will get rid of CO, unlike substances like lead or arsenic.

Household carbon monoxide alarms are readily available and recommended by the National Fire Protection Association. The installation of a CO alarm inside your home will provide early warning of accumulating CO. Currently, CO alarms sound when the concentration of CO in the air corresponds to 10% level in the blood. Since this is at the very low end of CO poisoning, the alarm may sound before people feel particularly sick. If your CO alarm sounds, have everyone move to an area with fresh air and report the CO alarm to your local fire department. Be on the lookout for any symptoms of CO poisoning and get medical attention immediately if anyone shows signs of CO poisoning. For more information on carbon monoxide visit www.nfpa.org

Parking & Transportation Services Receive Clean Air Award

Contributed by Environmental Specialist, Heather Perry

Stanford's Parking & Transportation Services (P&TS) received a Clean Air Award from the American Lung Association (ALA) of the Bay Area. The Department of Environmental Health & Safety nominated P&TS for the award in the category of Outstanding Transportation Program, recognizing P&TS' "outstanding leadership in the design and implementation of clean air awareness programs in the workplace." P&TS' program is multi-faceted in its approach to environmental conservation and is aimed not only at improving air quality, but helping reduce traffic congestion, commute stress and daily parking hassles on campus by reducing the number of drive-alone commuters.

For further information on P&TS' extensive transportation demand management program, see their web site.

Emergency Preparedness Planning at Stanford University

Contributed by
Training and Communications Specialist, Susie Claxton

Our Stanford University Emergency Preparedness Planning effort is ongoing. Roni Wade, the campus Emergency Preparedness Planning Program Manager, has updated the Campus Emergency Plan and the Cabinet Emergency Planning Guidelines. These plans, along with the Department Emergency Planning Guidelines have been posted to our EH&S web pages. The Cabinet and Department Guidelines have been posted as MS Word documents as well so that emergency planning teams can download and customize these plans for their functional areas.

At an Emergency Preparedness meeting for Satellite Operations Centers (SOCs) held on April 17th, the SOCs were asked to revise their emergency plans by this summer. If you need help updating your plans, please feel free to contact EH&S to arrange an appointment

Surplus Chemicals Available Free to Campus Research Community

Contributed by Environmental Specialist, Heather Perry

As part of its overall Environmental Stewardship Program, EH&S has established a Chemical Redistribution Program for the campus research community. We have an inventory of unused, unopened surplus chemicals that are available free of charge. Laboratory personnel may simply review the online surplus chemical inventory to see if any of our surplus materials could be utilized in their research. EH&S will deliver the chemicals to the laboratories of interested researchers.

This program gives researchers a unique opportunity to have a direct and positive influence on the environment by reusing materials that would otherwise be disposed of at a significant cost to the environment and the University's budget.

If you have further questions about the Surplus Chemical Redistribution Program or would like to participate, you may contact Heather Perry at 3-1308.

West Nile Virus

Contributed by Biosafety Officer, Ellyn Segal

West Nile is a mosquito-borne virus that was first detected in the United States in 1999. The virus, which causes encephalitis, or inflammation of the brain, has been found in Africa, Western Asia, the Middle East, the Mediterranean region of Europe, and, most recently, in the United States. The continued expansion of West Nile virus in the United States indicates that it is permanently established in the Western Hemisphere.

Mosquitoes acquire the West Nile virus (WNV) from birds and pass it on to other birds, animals, and people. While humans and horses may be infected by the virus, there is no documentation that infected horses can spread the virus to uninfected horses or other animals; additionally, except for cases of organ transplant, it does not appear that humans spread the disease to other humans.

The best way to protect against West Nile virus is to protect yourself and your family from mosquito bites. For information on mosquito control at Stanford University, see the Stanford Report article regarding the West Nile Virus.
