Zevachim 3:1-2

Zevachim 3:1

If a person who was unfit to perform the Temple service slaughtered a sacrifice, it is valid because slaughtering performed by non-kohanim, women, servants and those who are ritually impure is valid, even for sacrifices of the highest degree of sanctity, provided that the ritually impure person doesn’t touch the flesh (which would render it likewise ritually impure). Accordingly, improper intentions on the part of one of these people would invalidate a sacrifice. If any of these people collected the blood intending to eat or burn the sacrifice after its proper time or outside of its proper place, then if there is any lifeblood remaining, a kohein who is fit to perform the service collects the blood again.

Zevachim 3:2

If someone who is fit to perform the service collected the blood and gave it to someone who is unfit, the latter must return it to the former. If one collected the blood with his right hand and transferred it to his left hand, he must return it to his right hand. If one collected the blood in a Temple vessel and transferred it to a secular vessel, he must return it to a Temple vessel. If it spilled from the vessel to the floor and he retrieved it, it remains valid. If he sprinkled the blood on the ramp rather than on the base, or if he sprinkled above what must be sprinkled below, or vice versa, or if he sprinkled outside what must be sprinkled inside, or vice versa, then if there is lifeblood remaining, a fit kohein must perform the collection again.
