I hope the mods will forgive me for resurrecting an old thread that I think is worthwhile. I realized in June of ‘06 that I had not seen discussion on the importance of proper ventilation and airflow, both for protecting those not ill with the flu who are caring for the sick, and for general health for those SIP without power. I had planned to use a Kearney Air Pump if the power went out to ventilate our home; here is a link to the source document: http://www.oism.org/nwss/s73p917.htm

During both hot and cold weather, the ability to move air around without any power would appear to me to be an important capability; the KAP is only one way to do this.

If anyone else has a suggestion for effective positive ventilation I’m interested. Any other suggestions?

 Proper filtrated air flow is critical in maintaining a saferoom

environment and can not be properly achieved without a positive filtrated air source; however I agree most filtration devices operate on a AC current, without a DC back up.The unit I am familiar with and have procured for our home is supplied by the people at smartroom. This is a link to their site www.birdflusaferoom.com The system we purchased was the Ultra Violet Airlock with a biological filtration unit that operates on both AC and Dc current for a back up electric source.I hope this information may be of help to you.

 There is a basic a understanding individuals must have relating to overall preparedness for any potentially readily transmitted fatal disease.

My experience and education has led me to the following conclusions. You have to define the basics and answer these questions.

 1. The most important elements for overall protection and safety

requires,Proper food supply and storage for the overall time that you may have to sustain yourself.

 2. Adequate clean water supply and personal hygeine items required

for the expected duration.

 3. A backup electrical source. IE: Batteries or a battery bank,

a generator.

 4. A biologically fitrated air supply to create a positive pressure

envelope within your selected area for a saferoom or an isolation unit. Insure that the air filtration system will make at least four complete air changes per hour.The system must be able to operate on AC as well as DC current.

 5. A communication system and materials to entertain the children and adults as well.
 6. A sufficient supply of masks and sanitizing wipes and or agents.
 7. A first aid kit.
 8. Familiarize your family and practice simulated drills so everyone is familiar with the overall preparedness plan.
 9. Replace being properly prepared with fear and panic.

I’m really curious if people understand the difference between positive and/or negative air flow and passive air filtration. I’m also wondering what the level of understanding is in regard to the role of an airlock? or even what is an airlock? I think I know the anwsers to these questions however when I think I know the anwsers then I realise all of the questions have been changed. Previous threads regarding aerosol transmission, particularly the following post by Pixie, on Sept 26, are a knowledge base for all of us. http://www.fluwikie2.com/pmwiki.php?n=Forum.AerosolTransmissionOfInfluenza

Dr Garwin, IBM Fellow Emeritus, of the Thomas J. Watson Research Center, has written on November 10th “There are many basic things we don’t know about how influenza is transmitted,” said Dr. Garwin of IBM. “For example, it appears that a relatively low number of people catch the flu from another person. Breaking the transmission chain with non-pharmacological measures has proved challenging, but the prize is enormous.”

Often also neglected, according to the authors, are protective measures that fall between individual protection and the whole population — “the excluded middle”-- such as buildings, facilities and smaller areas such as work places and homes. Examples might include improved air-handling systems, room-size fans, portable air-filtration systems, or physical barriers such as room dividers and doors

Powered or unpowered portable air filtration systems and decontamination or airlocks which act as physical barriers are now beginning to be discussed. The airlocks in conjunction with air filtration systems are what create positive or negative circulating, fresh air versus passive air. Passive air systems are not pulling fresh air into a room or containing or circulating the air in a defined space.

I look forward to reading the thoughts of others. Thanks.
