Thanks for your query.
I will try my best to provide you with best possible professional recommendations to your questions.
"Clear" body fluids such as tears, saliva, sweat and urine contain little or no virus and do not transmit HIV
unless they are contaminated with blood. But you have said it is contaminated with blood.
Exactly how long HIV virus survives outside the body depends on a lot of factors such as temperature, presence of fluids/moisture etc. On the other hand, HIV infected blood stored in a blood bank
can remain infective for weeks or as long as the blood is adequately stored. Suffice it to say that under normal conditions, virus present in blood or other body fluids does not survive for long if the fluids dry up, or are exposed to sun or heat. This time is a matter of hours at most.
As far as your accidental exposure, i think you need not worry as there is very little chance that you would be infected.
Still i advice you to seek immediate assessment and treatment from your employee health unit
, your private physician or the emergency department. If anti-HIV medication is indicated, it should be taken as soon as possible.
Yet again, I do hope that you have found something helpful and I will be glad to answer any further queries.
