a child got locked in a room is one permitted to break the door?
The gemora Yuma
84b says that if a child got locked behind a door one may break
down the door even if it involves a biblical prohibition. The
gemora says that even if one needed the splinters for firewood and
is cutting the door in a manner which will thus benefit him, it is
permitted. The Sha’ar Ha’tsiun 328:17 says that obviously one
must break the door in the quickest method possible. He may therefore
not cut the door in a manner benefiting him if it requires doing more
HaShulchan asks how the gemora can permit such a method of
cutting when one can simply break down the door. He answers that it
would frighten the child.
We see from here that
leaving a child behind a locked door involves pikuach nefesh
and everything must be done to release him from his prison.
A door came off its hinges into my hands, am
I permitted to return it?
Although a door
revolves on its hinges, in the eyes of the halacha it is
static, being that it is not carried from place to place.
That does not mean that one is forbidden to open or shut a door, it
means that if it came off it is hinges it is muktze.
Removing the door
from its hinges on Shabbos is forbidden because of Soter –
Dismantling, but if it did happen, then A) one is forbidden to place
it on its hinges, due to the biblical prohibition of Boneh –
Construction, B) the door is muktze.
What then, am I supposed to do with the detached door?
Since it is muktze
it may not be moved from place to place and ideally it should be left
exactly where it is. However, if it poses a threat because either
people might trip over it or it might fall onto someone; it may be
relocated elsewhere until out of harm’s way.
the mechitza – screen between the men and the women fell down, is one
permitted to stand it up again?
is based on a few factors. One is biblically forbidden to erect a
permanent tent on Shabbos, even if he does not thrust pegs into the
ground or knot rope to hold up the tent. The prohibition is based on
the melacha of Boneh – Construction and tent building is
included. Chazal were afraid that if one were to erect a
temporary tent it would lead him to construct a permanent one, and
hence instituted a g’zeira (rabbinical prohibition) forbidding
the erection of even a temporary tent.
Shabbos 125b, says that a screen or partition does not fall into
this category unless it creates a halachik wall (which will
soon be explained). The Mishna Berura
teaches us that one may erect a screen used for separating between men
and women at a shiur, provided that it is temporary, otherwise
it will fall into the category of Boneh.
What is the halacha with regards to setting up a screen to block out
If the erected screen
is temporary and no nails/screws etc were employed to set it up, it is
permitted. Blocking out the sun is not a halachik screen
What then, is a halachik screen?
screen creates an entity where without this partition a certain
halachik requirement would be lacking.
For example: a kosher succah is
comprised of three walls. One is forbidden to add a third wall to two
existing ones, even if the third wall would be a temporary screen,
because the third wall ‘creates’ a succah and without this wall the
succah is not a kosher succah.
