Biur Chametz

From Halachipedia

How to do Biur Chametz

  1. The minhag is to burn Chametz (until it becomes coals or ashes) during the day, however, one fulfills the mitzvah by destroying the Chametz in any fashion. [1]
  2. It is preferable for one to burn his own chometz and not to appoint someone else to do it for him [2]
  3. One should cut the chametz into thin slices in order for it to burn properly. [3]
  4. One should leave over at least a kezayit of chametz that he is not selling to a non-jew in order to properly fulfill this mitzva. [4]
  5. It is permitted to throw the chametz into a field with a lot of birds, but if the person notices that at the prohibited time for chametz, the birds haven't eaten it yet, he should destroy it immediately. [5]
  6. One fulfills the mitzvah of destroying the Chametz by flushing it down the toilet. [6]
  7. It is forbidden to do melacha once the time for burning comes until you burn the chametz. [7]
  8. If the chametz has turned into charcoal that is considered burnt enough. [8]
  9. If one puts Chametz in one’s private garbage bin one should either pour Ajax on the Chametz to make it totally inedible [9], or put it in the street and declare that it be ownerless in front of three people. [10]. One can also include them in the sale of the chametz to a non-jew but then they cannot be used by him over pesach. [11]
  10. It’s preferable to burn the Chametz without dousing it in gasoline or lighter fluid so that one can destroy the Chametz with fire and not to make it inedible using any other means. [12] If the chametz will not burn in time without the gasoline then one should pour it to speed up the burning. [13]
  11. There is a custom to burn the ten pieces of chametz that were hidden for the bedikah along with the rest of the chametz during biur. [14] There is also a custom to burn the lulav, [15] the aravot used for hoshanot [16], leftover chanuka candles and wicks [17] and fingernails [18] along with the chametz.
  12. One should throw the chametz with his right hand. [19]
  13. One should burn the chametz in one's own property. [20]
  14. One doesn’t have to do Bitul Chametz after Bedika of the Shul or Bet Midrash [21] unless it belongs to an individual in which case one should do Bitul Chametz. [22]

Beracha

  1. There is no beracha recited before the burning. The beracha of al biur chametz is recited before the bedika. [23]
  2. If someone forgot the beracha the night before on the bedika, he can recite the next day on the burning. [24]

When

  1. If one sold one’s Chametz one shouldn’t do Biur Chametz until after the Rabbi sells the Chametz to the goy which is usually done at the beginning of the 5th hour. [25]
  2. Some say that one should specifically burn it at the beginning of the fifth hour. [26]
  3. If chametz is found during pesach, see [[2]]
  4. The nullification during the day should be done before the sixth hour, so that the chametz that you nullify is still yours when you nullify it. [27] but after the burning. [28]
  5. If one leaves his house, he should still do bitul when the time comes. [29]

Erev Pesach on Shabbat

  1. When the fourteenth of Nisan occurs on a Shabbat, all chametz must be destroyed before shabbat except for the chametz that will be needed for the first two shabbat meals. [30]

  1. S”A and Rama 445:1, Mishna Brurah 445:1. This is based on the Mishna in Pesachim 21a which records an argument regarding how to fulfill the obligation in Shemot 12:15 תַּשְׁבִּיתוּ שְּׂאֹר מִבָּתֵּיכֶם. Rabbi Yehuda says the only way is to burn while chachamim say you can burn it, crumble it, or throw it into the river. The Gra 445:1 says that even chachamim say that ideally one should burn it, as the Mishnah states one can "even" (af) eliminate it in other ways. He addsvthat the only reason this is only a custom and not obligatory is because according to rabbi yehuda you need to burn the chametz after its prohibited time and since we do it before that we can really do it any way. Kaf Hachayim 445:11 says that there is special kabbalistic importance to burning the chametz because it symbolizes burning the evil inclination.
