Unless you are in a severe accident, or you work in the medical field, this is not a concern.
I repeat - there is NO possibility of infection from blood in the environment. Not ever.
Any blood you encounter on surfaces or objects CANNOT infect you with HIV.
The only risks for HIV in adults are:
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles with IV drug users.
There is nothing else you can think of that would put you at risk for HIV.
