Can you help
At present i am about to embark on a demolition project that entails a buliding dating back to the Victorian period. Certain products e.g hay and straw was used in the concrete and mortar mix to help with the bonding. During the demolition process dust could cause respiritory problems from the spores embeded within. Possibly causing Farmers lung.
Has anybody come across the same problem? if so what was your control measures and can you give further advice.

I think you'll find Farmers Lung is not the problem that you will encounter. However the dust is a significant problem, as may be the biological assay for such as anthrax. The exposure to grain dust was pretty phenomenal for farmers before the enclosed combine cabs were developed and this was one of the major causes, although silage and hay moulds/spores could cause some problems. My own uncle used to come in from harvest caked in the dust and was often invisible in the fog of dust. He like many others suffered a debiliating retirement period and early death as a consequence. The long term problems of dust are difficult to get across to operatives and you will find almost a perversity in avoiding the following of any set procedure.

You must consider various aspects of microbiological agents.
Agent. Disease or Infection. Source.
Pencillum spp. Rhinitis, asthma, alveolitus. Building fabric.
Serpula Lacrymans (dry rot). Rhinitis, asthma. Building fabric, old timbers.
Aspergillus spp (especially A.Fumigatus and A.Niger. Rhinitis, asthma. Building fabric, old timbers.
Mucor spp. Rhinitis, asthma. Building fabric, soil.
Cladosporium spp. Rhinitis, asthma. Building fabric.
Clostridium tetani. Tetanus, lockjaw. Soil.
Chlamydia psittaci. Orthinosis. Bird droppings, feather nests.
Histoplasmosa capsulatum Histoplasmosis. Bird and bat droppings.
Leptospira icterohaemorrhagiae. Weil's disease - leptospirosis Mainly rats but also cats, dogs and cattle urine.
Bacillus anthracis Anthrax Spores of leather horse hair or wool products.
Variola major or minor. Smallpox Infected mummified skins.
(can send this direct as word document - if required).
Controls for anthrax spores and the like are required, this may include decontamination.
Lead maybe in the paint.
Asbestos may be possible on alterations since being constructed.
the controls must be developed, adopted, understood and monitored.
