Reducing exposure to avian flu virus
April 1st 2006

Although Avian flu viruses such as H5N1 do not usually infect people, several instances have been reported in various locations.

UK government bodies such as DEFRA and the HPA have contingency plans in place to protect people.

Alan McArthur, technical advisor, 3M occupational health and environment, explains "In environments where people are at risk of exposure to avian flu, adequate respiratory, eye, hand, foot and clothing protection should be worn to minimise the risk of contamination."

For those involved with disease control and eradication, DEFRA advises that an FFP3 respirator with exhalation valve offers suitable protection against airborne transmission. Where a good seal cannot be achieved, for example due to facial hair, a full hood powered respirator should be considered. 3M supplies two EN149:2001 FFP3 respirators for industrial and consumer applications: the 8835 and 9332. A comprehensive range of powered air respirators is also available.

The company stresses that the fit of the respirator is very important. If it does not seal properly to the face, airborne hazards can penetrate or enter the breathing zone.
