Mishnah Zevachim 3:1: If people who are ineligible [to serve in the Temple] slaughtered [an offering], their slaughtering is valid, since slaughtering is valid if performed by non-priests, by women, by slaves, and by impure individuals. This is so even for Kodshai Kodashim [sacrifices of the highest degree of sanctity. They may be slaughtered only on the north-west corner of the altar, and consumed only within the Temple compound by male priests, or burnt entirely] provided that impure individuals do not touch the meat. Therefore, these [people] invalidate [offerings] through [unlawful] thought. [If such ineligible] people collected the blood [with the intention of acting] after its proper time or outside its proper place, an eligible person should return and collect [blood] if there is still life blood [in the animal].

כל הפסולין ששחטו, שחיטתן כשרה. שהשחיטה כשרה בזרים, בנשים , ובעבדים, ובטמאים, אפלו בקדשי קדשים - ובלבד שלא יהיו טמאים נוגעים בבשר. לפיכך הם פוסלים במחשבה. וכלן שקבלו את הדם חוץ לזמנו, וחוץ למקומו, אם יש דם הנפש - יחזור הכשר ויקבל.
 

Mishnah Zevachim 3:2: [If] an eligible person collected the blood and gave it to an ineligible person, he [the latter] should return it to the eligible person. [If] he collected the blood with his right hand and transferred it to his left hand, he should return it to his right hand. [If] he collected it in a consecrated vessel and then transferred it to a non-consecrated vessel - he should return it to the consecrated vessel. [If the blood] spilled from the vessel on the floor and he gathered it - it is valid. [If] he sprinkled the blood on the ramp, [or] at a spot not next to the base [of the altar], [or] if he sprinkled [blood] that should be sprinkled below [the altar's midpoint] above [it], [or if he sprinkled blood] that should be sprinkled above the altar's midpoint] below [it], or [if he dashed blood] that should be [sprinkled] inside [the Temple on the inner altar, on the] outside [altar], or [if he sprinkled blood] that should be [sprinkled on the] outside [altar] on the inside [altar], an eligible person should return and collect [blood] if there is still life blood [in the animal].

קבל הכשר ונתן לפסול - יחזיר לכשר. קבל בימינו ונתן לשמאלו, יחזיר לימינו. קבל בכלי קדש ונתן בכלי חל - יחזיר לכלי קדש. נשפך מן הכלי על הרצפה ואספו - כשר.נתנו על גבי הכבש, שלא כנגד היסוד, נתן את הנתנין למטה - למעלה, ואת הנתנים למעלה - למטה, את הנתנים בפנים - בחוץ, ואת הנתנין בחוץ - בפנים, אם יש דם הנפש - יחזור הכשר ויקבל.
