Hi Ronnie,
The howie Code qwas replaced about 10 years ago by the HSC (Health and
Safety Commission)  document.
"Safe working and the prevention of infection in clinical laboratories" and
" Safe working and the prevention of infection in the mortuary and
post-mortem room" are available from the HMSO Publications centre and HMSO
Bookshops. I can give you the ISBN numbers if you are interested.
