Smoke-Clearing Technology May Come From Poultry House Air Scrubber

A device invented by the Agricultural Research Service (ARS) to clean dust and microorganisms from the air of poultry houses may also help people escape during fires and make it easier for fire fighters to locate people in smoke-filled rooms.

The technology was originally developed by ARS agricultural engineer Bailey Mitchell, with the agency's Southeast Poultry Research Laboratory in Athens, Ga., to trap airborne particles like dust and microbes in poultry houses. Unlike previous technology, which was typically large, bulky and expensive, costing from $1,000 to $25,000, Mitchell's machine is relatively small and could be portable and battery-operated.

ARS has already licensed the device, called the Electrostatic Space Charge System (ESCS), for agricultural applications to Baumgartner Environics, Inc., of Olivia, Minn.ESCS generates a negative electrostatic charge on dust and other airborne particles, causing them to be attracted to grounded surfaces like walls or the floor. Unlike most air cleaners, it does not require air to move through it for cleaning to occur.

Mitchell used a smoke generator to demonstrate ESCS's abilities, which gave rise to the idea that the device can clean the air of smoke just as easily as it does dust and microbes. What still needs to be tested is just how fast it can actually clear smoke to provide a reasonably clear field of vision, according to Mitchell.

By mounting the self-contained, waterproof device in areas such as stairwells or hallways, it may be able to give people a clearer path to exits in the event of a fire. In addition, since the device can also be portable, firefighters could carry one into smoke-filled buildings to make it easier to find people who have been overcome.

The device is also lightweight and may be of use in clearing smoke from airplanes and trains as well.The University of Pittsburgh\'s FirstLink program, which has a contract with the U.S. Department of Defense to seek out new technology for first responders, is planning a series of tests and demonstrations to document the device\'s ability to clear smoke from the air.ARS is the U.S. Department of Agriculture\'s chief scientific research agency.

TITLE: SMOKE-CLEARING TECHNOLOGY MAY COME FROM POULTRY HOUSE AIR SCRUBBER

ALAM BA NINYO NA NATUKLASAN NG MGA EKSPERTO NA ANG DEVICE NA NAGLALAYONG LINISIN ANG MGA ALIKABOK AT MICROORGANISM SA POULTRY HOUSES AY MAAARI NA RING MAGAMI T NG TAO PARA MAKALIGTAS SA ANUMANG SUNOG AT MAS MADALI PARA SA MGA PAMATAY SUNOG NA MAKITA ANG MGA TAO SA LOOB NG NASUSUNOG NA GUSALI O BAHAY?

ANG NATURANG TEKNOLOHIYA AY ORIHINAL NA NAISAKATUPARAN NG ARS AGRICULTURAL ENGINEER BAILEY MITCHELL PARA MA-TRAP ANG MGA AIRBORNE PARTICLE TULAD NG ALIKABOK AT MICROBES SA POULTRY HOUSES.

ANG NATURANG DEVICE AY TINAWAG NA ELECTROSTATIC SPACE CHARGE SYSTEM PARA SA AGRICULTURAL APPLICATIONS AT ITO AY NASA PANGALAN NG ENVIRONICS, INC NG OLIVIA MINNESOTA.

ANG NATURANG DEVICE AY MAY KAKAYANANG MAG-GENERATE NG NEGATIVE ELECTROSTATIC CHARGE SA MGA ALIKABOK AT IBA PANG AIRBORNE PARTICLES, DAHILAN PARA MA-ATTRACT ANG MGA ITO SA GROUNDED SURFACE TULAD NG DINGDING O KAYA AY SAHIG O FLOORING.

KAPAG MOUNTED ITO SA MGA LUGAR TULAD NG HAGDAN O HALLWAYS, ANG MGA TAO AY MERONG GIYA NA MAKALABAS SA GUSALI O BAHAY KAPAG MAY SUNOG.
