To make a lantern with a flashlight

Tweet of the Metropolitan Police Department Disaster Countermeasures Division

　The Metropolitan Police Department's Disaster Control Division introduces how to use flashlights and use it like a lantern.

　Complete just put a plastic bottle with water on the flashlight.If the flashlight is small, you can put it in a cup and put a plastic bottle on it.

Produced in 3 minutes in "salad oil lamp" for power outage countermeasures, and the fire lasts for a long time.

　What if the battery of the flashlight was cut off due to a sudden power outage such as a disaster?In case of emergency, we will introduce how to make a lamp using salad oil.If you get used to it, you can make it in 2-3 minutes.

　Eiji Ito of the Citizen Disaster Prevention Research Institute, a public interest incorporated foundation, taught how to make it.

　The ingredients are tissue paper used for lamp, aluminum foil that fixes light, transparent glass cups and jams.Salad oil is better because the smell is less if you are not using it.

　Mr. Ito says, "It burns for about 3 hours and lasts for about 3 hours with 5 grams of oil. Even if the container falls, the salad oil has a high ignition point and does not ignite at room temperature, so it can be used safely.I talk.Kerosene and gasoline are dangerous, so don't use them.

　Peel out one tissue paper with two stacked tissue and cut it into 5 equal parts.Roll one cut with the palm of your hand until it becomes hard.If the tip is cut diagonally with scissors, the cross -sectional area will increase and it will be easier to fire.

　If aluminum foil is also a general home size, the width remains the same, but cut 3 cm.Drill a hole in the folded aluminum foil with a toothpick, insert the light, and put the tip 3 to 5 mm.Attach the aluminum foil to the container and pour while applying oil to the tip of the lamp.

　Finally, put on the fire to complete.The fire disappears if you breathe.Be careful when handling fire, such as when you leave the lamp.Also, choose a heat -resistant glass.(Mitsuki Mori)

If the water stops

　What do you do if the water supply that you usually use as usual stops?

3 liters per person per day

　Do you know how much the amount of water that the human body needs a day?The answer is about 3 liters.

　"You may think that there are many, but you can explain it with the" income and expenditure "of the body," said Kazuko Okuda, an advisor to the Japanese Disaster Food Society.While water comes out of the body due to urine and sweat, it is taken into the body from drinks and food.The amount is about 3 liters a day.If water is unable to replenish, it becomes dehydrated.

　In the Great Hanshin Earthquake, which was also affected by Mr. Okuda, it took about three months for the water supply in Hyogo Prefecture to be completely restored."Drinks are essential in the event of a disaster that makes it difficult to get moisture from meals. Stockpiling at home is important to connect life," he said.3 liters of water can be supplemented not only with water but also with tea or juice.

　The country also calls for 3 liters per day, "prepare for three days," but it is said that a large earthquake, which is expected to be damaged, requires more than one week's worth of stock.

　However, the actual preparation of ordinary households is not very important.In a questionnaire conducted in 2014 by a major beverage maker "Kirin Beverage", about half of the family responded that mineral water was zero.The most common reason was "difficult to manage the expiration date" (31.5 %).The expiration date varies depending on the size of the manufacturer and container."Let's check the expiration date of the beverages twice a year, such as the day of the East Japan, the day of the Great Hanshin Earthquake, and the day of disaster prevention," said Takamasa Wada.

　In addition to the purchase of mineral water, there is also a method of placing tap water frequently.If you put your eyes in a container and seal it, and avoid direct sunlight, you can generally drink for about 3 days safely.However, water through a water purifier requires no disinfecting effect of chlorine, so it is necessary to replace it every day.In addition, I would like to prepare transportation tools such as plastic tanks and carry carts in preparation for using a water station.

　How about "living water" used for face washing, washing, and toilet?

　It will be useful if there is a remaining hot water in the bath and a tap water for the hanging.Be careful when using river water.If the surrounding factories are damaged or the sewer pipes are damaged, there is a risk of contamination.In the event of a disaster, immunity is likely to decrease.Mr. Wada pointed out that "it is dangerous to wash dishes and body with contaminated water and poor preserved water."

　The important thing is "unused ingenuity."If you wrap a dish in wrap or aluminum foil, you will not have to wash it.Wettish is helpful to keep your body hygiene.According to Shiseido, which also sends beauty information in an emergency, there are many sebaceous glands that emit odors in the center of the chest, the upper part of the back, under the armpits, and the pubic area.It is good to wipe these parts and the back of the ears that are easy to accumulate dirt and sweat.

What do you do with stockpiling space?

　Despite the fact that you can protect your life, you can stock up a drink that struggles with space.It is 36 liters for three days for a family of four, and 18 plastic bottles of 2 liters.

　There are also ideas to use dead space such as under the table, wrap the cardboard with a drink with your favorite wrapping paper or cloth, and use it as a table or chair.

　In the case of apartments, it is also a good idea to talk with residents in advance and stock them in common areas that can be stored for a long time.Especially in high -rise apartments, when the elevator stops, it becomes difficult to transport water from the water station.I would like to stock up in two common areas on high and lower floors.

Active in the event of a power outage, home sunlight

　Household solar power generation equipment that has become completely familiar from the growing interest in renewable energy and the fixed -price purchase system.However, it is not well known that it can be used as a power supply during a disaster or other power outage.Even in the affected area of the Kumamoto Earthquake (April 2016), where up to 476,600 units had a power outage, solar power installed at home was active.

　Masugi -cho was hit twice at seismic intensity 7 and was severely damaged.The area where a male employee who newly built a house was built three years ago was a power outage after the "pre -earthquarters" on the night of April 14, and continued intermittently until the night of the 18th.What helped me was a 4 -kilowatt output on the roof.

　Normally, all electricity generated by solar panels is all flowing to the power company through a power conditioner (power control) and sold to power companies.Conversely, all electricity used at home is a mechanism to buy from the transmission line.If the power outage is, the power control will automatically stop power transmission.

　However, if the switch on the power control is switched from normal "interactive operation" to "independent operation", electricity generated without transmission lines can be used directly.There are outlets for 90 % of the power control models, and electrical appliances can be used up to 1500 watts.

　During the power outage, the man inserts an extension cord for mowing into the power control near the entrance, and in the daytime when the sun is out, puts the TV in the parking lot in front of the house to collect information.Warm retort curry in a microwave or boil water in a pot.I was able to cool the food that I couldn't eat at the shelter in the refrigerator.

　Men have struggled with long -term power outages during previous typhoon damage."I bought sunlight for power selling, but in that case it was a lot useful."

　Statistics of the Ministry of Internal Affairs and Communications has 1.57 million houses nationwide in 2013.It increased tripled in five years.However, many people do not know that switching to independent driving can be used in the event of a power outage.

　At the end of April after the NPO, about 20 households with solar power generation facilities in the affected areas such as Mashiki -cho, at the end of April after the earthquake, only three households used independent driving during a power outage.。More than half of the households did not know independent driving.According to Tsuzuki Koto, representative director, "The dealer has no knowledge and is not explained properly."

　In order to use independent driving, it is the rule of thumb to cut the main power supply breaker and solar power breaker to prevent fire or accident when electricity from the transmission line is restored."It is necessary to try independent driving in normal times in case of emergency," Tsuzuki says.
