DWP IIAC Cm6867
“Extrinsic Allergic Alveolitis”
EAA is a very rare disease and can almost always be traced to an occupational exposure. When a disease could arise from several possible causes IIAC look for evidence of a doubling of risk associated with an occupational cause. No such statistical evidence was available for EAA in respect of metalworking fluids; IIAC relied upon the rarity of the disease to conclude that it was too much of a coincidence that one workplace would have more than one case.
