Question No. 333
Category Shabbos (Sabbath Laws)
Date Posted Early 2004
The Question I know that we're not allowed to use lights on shabbos, because when we turn them on that might create a spark somewhere in the generator. But what if we were to come up with a method of creating lights (by the use of chemicals or nuclear reactions) where no sparks are involved. Are we allowed to use them then, and also, how does this opinion extend to the use of electricity that has nothing to do with lights? Anonymous, USA

The Question I was very impressed with my neighbor's dog last week. When you put a piece of challah on a shelf above the light switch, the dog jumps up and turns the switch on or off as it gets the challah. If the lights go off for some reason on Shabbat and need to be turned back on, is it okay to put a piece of challah on that shelf? Thank you. David, Pennsylvania

The Question How was the Hebrew Sabbath established and does it begin Friday evening and end Saturday evening or continue until sunrise on Sunday. Please forgive my ignorance on this subject but I am a gentile with little knowledge of such things...although I am willing to learn. James, Florida

The Question Shalom Aleichem! I was asked about the doors one increasingly finds in hotels today that must be opened by electronic card. It appears most such doors have manual overrides, so they can be opened by a conventional key in an emergency. Therefore, a non-Jewish hotel employee could open such a door without resorting to malacha, if he wanted to. It is to save the time required to hunt down a manual key, that he uses the electronic one. So, in such a scenario, may one ask the non-Jew before Shabbos to open the door for him on Shabbos, even if he thinks the non-Jew will use the electronic card, because since he could use the manual key, should he use the electronic one, adaytei denafshei ko-oved? Would one need to have the non-Jew open the door for him at least once during the week as well? Yitzchak Shuster

The Question Are there opinions permitting the use of can openers and vegetable peelers on Shabbat? In Israel, I know of many shomer-Shabbat people who would use scissors to open bags of milk. Outside of Israel, no one has seemed to have heard of this. Is there a difference between the scissors and the peeler/opener? Thank you. David, Pennsylvania

The Question In the news this Friday, there were 2 fires in the North of Israel. I know that barring a danger to life, one is not to directly extinguish a fire on Shabbat. However, what is the responsibility of the state in this regard? If the fire cannot be extinguished before Shabbat and there is enough time to tell people to evacuate before Shabbat, are they allowed to continue fighting the fire on Shabbat? Does it matter if the fire is near a Jewish neighborhood, a non-Jewish neighborhood, or in the middle of an uninhabited area? In general, what are the halachic guidelines of a Jewish state with regards to keeping Shabbat as compared to a Jewish individual? Thank you. David, Pennsylvania

The Question We use a dud shemesh that contains an electric element for heating the water on cloudy days. We don't actually use the element as we have a junkers for an alternate source of hot water. If we disconnect the switch for the electric element, would it be permissible to use the dud shemesh on Shabbath? Thank you. David Waxman, Jerusalem

The Question Is it permissible on Shabbos to adjust an electric timer (when the adjustment itself involves no direct melacha) in order to turn on an appliance later on in the day? We have timers which turn appliances on and off based on little plastic pegs placed on a disc which rotates during 24 hours. (example: if the air conditioner is off at 10am, can I move a peg to 10:30am so that it will switch on at that time?) Yaakov Bock, New York

The Question Two questions regarding infants on Shabbat. In my previous community, I was told that it was not okay to use the diaper's velcro or tape to close the dirty diaper. When I moved to a new community, I was told that that the velcro was definetly okay, and the tape might be also. How does the Rav feel about this issue. Secondly, in my previous community, I was told that it was okay to wind up a manual baby swing. In my new community, I was told that this is prohibited. How does the Rav hold on this isssue. In addition, would it make a difference if the manual swing has a little diplay on it that tells if the swing is fully wound or half wound or not wound at all. If that is a problem, could one just over up the display? Thank you. Anonymous

The Question I have been told different opinions regarding the use of deodorizing/sanitizing agents on Shabbat that are activated during flushing. Usually, they change the color of the water to blue. Is this a problem? In additon, many of them start off as a solid until the water running over them activates them. Would this be a problem? Thank you. Anonymous
