When the collection of its ashes was completed, anyone who is involved with it - i.e., with the division of its ashes or with setting them aside for safekeeping - or who touches it, is pure. These principles do not apply to the red heifer alone, but also to all the sin-offerings of bulls and goats that are burnt. One who burns them imparts impurity to his garments while he is burning them until they are reduced to ashes. For behold, with regard to the bull and the goat burned on Yom Kippur, Leviticus 16:25 states: "The one who burns them shall launder his garments." According to the Oral Tradition, it was taught that this is a general rule applying to all those who burn sacrificial offerings, teaching that they impart impurity to their garments until the offerings are reduced to ashes. When does the above apply? When no disqualifying factor occurred and they were burned in the ashheap as prescribed. If, however, they were disqualified in the Temple Courtyard, they are burned there like disqualified offerings and the one who burns them is ritually pure. Similarly, one who is involved with these offerings after they have been reduced to ashes does not impart impurity to his garments. Who is considered as "one who burns" it? Anyone who helps in burning it, for example, one who turns over the meat, one who places wood upon it, one who fans the fire, one who stirs the coals so that the fire will burn, and the like. In contrast, one who kindles the flame and one who builds the arrangement are pure. According to the Oral Tradition, it was taught that one who carries the bulls and the goats that are burnt to transport them to the ashheap to burn them is ritually impure and imparts impurity to his garments according to Scriptural Law as long as he is involved in transporting them. To regain purity, he is required to immerse himself in a mikveh and wait until nightfall like the one who sends the goat to Azazel. The latter imparts impurity to all the garments and all the implements that he touches that are on him throughout the time he is involved in sending the goat to its destination, as ibid.:26 states: "The one who sends the goat to Azazel shall launder his garments."
