Translation:Shulchan Aruch/Yoreh Deah/282
Seif 1: A person is obligated to act with great reverence for a Sefer Torah and it is a mitzvah to designate a location for it and to honor the location and to glorify it to the utmost. And a person should not spit opposite (in the presence of) a torah or show his nakedness opposite it or extend his foot towards it, and a person should no rest it on his head like a burden and should not turn his back on it,unless it (the sefer) is ten tefahim higher than him. Rather, he should sit in front of it with seriousness and awe and fear, for it is the trusworthy witness to all creations, as it says “And it will be there as a witness against you,” and he should honor it to the best of his ability.
Seif 2: One who sees a sefer Torah as it is processing is required to stand in its presence, and everyone should stand until the person who is carrying it will stop and arrive in his place, or until it is hidden from their eyes.
HGH: But in front of our Humashim, there is no need to stand. And there are some who are stringent. One who hears of someone carrying a Torah scroll, despite the fact that he does not see it, he is required to stand.
Seif 4: A person should not hold a Sefer Torah and enter the bathroom or the bath house or the grave yard, even if it is covered in a cloth/kerchief and placed in his bag. And you should not read from the sefer until you distance yourself (at least) four amot (the length of a forearm) from the dead body or from the grave yard or from the bathroom. And he should not hold a sefer torah without a cloth covering.
Seif 7: It is forbidden to sit on a bed upon which a sefer torah lies.
HGH: And ever-the-more-so it is forbidden to place it on the ground, and this is the law of other (Jewish) books (as well). And even on the steps that are approaching the holy ark it is forbidden to place books, and person should not place a sefer torah on his knees and [rest] his two elbows on it. And it seems to me that this is the law for other books, too
Seif 9: All of those who are ritually impure (temeim), even menstruating women (nidot), are permitted to hold a sefer torah and to read from it, provided that their hands re not filthy or dirty.
