Posted By Ron Impey Unfortunately a vaccination against Weil's Diease is not a realistic option unless one is prepared from a local strain. You need to think about Hepatitis A immunisation. Also check that the workers have had the Polio jab, and their tetanus protection is up-to-date.

Posted By Frank Hallett You should not rely on vaccinations; really good information on relevant potential healthexposures combined with a thoroughly indoctrinated and effectively supervised hygiene procedure is your best bet. You should also consider whether it will need any supportive health monitoring or health surveillance; and if so - what. Frank Hallett

Posted By Frank Hallett Hi Chris I'm not so ambitious as to allege that I can do the ultimate in alchemy;'tho as an ex-FS SCBA & Fire Survival Instructor I can walk on water and through walls when required! All I do is seek to impress upon those exposed to the hazards that they have as much to do with the success of the process as anyone else - and then I try to get the client to ensure a suitably robust supervisory process to cater for the "it won't happen to me" approach.
