Ask martin_606 on general section, he is an expert in this kind of work and a top bloke if you just want advice.
Thanks Paul, most kind.
Sadly in this country you need either training or a license to treat a crime scene, hardly makes sense when we are apparently H&S mad.
Just make sure you have your PPE, overalls, mask, gloves and eye wear in case of any splashes and all cuts are covered up.
Cut out the contaminated area and bag up in a bio disposal bag, you can contact waste company to remove it, they charge around £35 per bag or needle bin + VAT.
If it hasn't penetrated the floor boards then spray with a biocide, either professional from a supplier. Make sure the windows are open to get some air flow in there, once the blood has gone and the stain successfully treated any smell should be gone, if it still smells days later, you've missed something maybe in the cracks or some carpet.
Price wise you should be looking at £100+ per man hour.
Hope we've been able to help.
Regards
Martin
