Water tank cleaning work supervisor 4 Just because it does not stand out too much, there are quite a few accidents of the water tank.  Twenty-five years ago, a population infection occurred in a mixed-use building in Kanagawa with cryptosporidium ( parasites that are parasitic on humans). There were 461 people with symptoms and 5 inpatients. It is caused by tap water that was supplied from the water tank in the building. Due to the failure of the drainage pump, sewage and miscellaneous wastewater were mixed into the water tank.  From the beginning, it has not been grasped as a simple dedicated water supply, management based on the standards (cleaning and regular water quality inspection once a year) has not been made. It is a terrible situation to imagine that sewage is a thing that comes out from under man, and it drank the mix.  About 10 years ago, the body of a man in his 40s nearly a month after his death was found in an outdoor water tank at a shopping center in Mie. He jumped from the facility, attempted suicide, broke through the water tank and died in the water. After the discovery, more than 100 inquiries were received from customers in a few days, but there were no reports of health hazards. One month has passed since the decomposition of the body of the organic matter and the upper part being released and still being exposed to wind and rain.  I don't know if it's because chlorine protected me well, but I don't mind if I drink a man, he's weird. I'm sorry if you're eating. Curious you! Contact us here!

Water tank cleaning supervisor 3 The only thing I remember in the lecture of the water tank is the experience of a former public health center staff member of Tokyo.  In the 1940s, residents of public housing complexes contacted the public health center to inform them that water smelled.  Perhaps at that time, the structure of the water tank was not in general. When he went up to the roof, he said that women's sandals were neatly aligned in front of the elevated water tank. I won't tell you from that. I looked around at the students in a way that made me think. I'm good at this guy.  When the housewife who became a neurosis goes up to the roof to throw herself, water is put in the tank which is not familiar. Did you think that it was convenient not to find it immediately than to fall and die? Whether this incident was affected or not is now locked on the top plate.  Do you know the tail of the mouse? It used to be used for pyramid lids. It is very strong, and it is this tail to keep the original form until the end though it melts gradually when the mouse which entered from the water distribution pipe drowns in.  Hobby Wal. However, it is such a lecture that remains in the memory after all. Of course, now, because it is a structure that can not enter the mouse insect, rest assured (on the contrary, if it is a facility more than 50 years ago, I feel uneasy). The back information of the industry is also not fun, and the inquiry is here! Language This page has been automatically translated. Please note that it may differ from the original content.

Water tank cleaning work supervisor 2 I can hardly remember the contents of the lecture. First of all, it starts with a thick book called "Building Environmental Health System", and in the "management of drinking water", the obligation and the significance of cleaning the water tank once a year is explained. Because the water tank is a tank where people store water that is taken directly into the body, I understand that it is a theory that it is necessary to keep it clean at all times. Then, it should be hygienic to be able to water the public tap water directly like a general household. In the case of multi-family housing and high-rise buildings, some problems arise. First of all, if a large amount of water is used at once, there is a risk that the supply will not be in time. If you store it in a container in advance, you can supply the necessary amount with plenty of space. The other is a matter of water pressure, and in the case of a normal building, the water only rises up to about the third floor. Therefore, it is necessary to increase the pressure by using a water supply pump. In addition, the performance of the water supply pump was poor in the old facility, and it was necessary to install another tank called an elevated water tank on the roof for a stable supply. It is a principle to raise the water stored below to the top once, and to supply water stably by gravity. It is very confusing, and the risk of water being contaminated along the way increases. It is a method that has been adopted inevitably because of the necessary evil. For safe drinking water management, please contact us here! Language This page has been automatically translated.

In our industry, it's hard to do business (although it's not that we can't do it) if we don't have a lot of qualifications. Because there is a relation to deliver it to the public health center as a "registration business", and there is a restriction that the qualified person cannot concurrently serve other qualifications, it will be prompted to acquire it as soon as it becomes an employee.  The first person to go to pick it up was the "water tank cleaning supervisor". It is a qualification necessary to get a long certificate of building drinking water storage tank cleaning business registration. In my memory nearly 25 years ago, it must have been a two-day lecture. It is four days when the attendance guide is seen again this time. Get. Even though it feels long enough for two days, does it take twice as long now? Everyone who receives it from now on, it is serious.  There is an examination, so listen to the class properly. It was threatened so, but it came up to Tokyo in the state which was irresponsible at all no. In fact, there was only an examination at the end that it would be much more difficult to fall. However, even if it is this, the difficulty might have gone up now.  Because it is an age when there is no net, I remember looking for a cheap place to stay at any rate in a commercial booklet and booked a hotel related to YMCA (Christian Youth Association) for 4,000 yen. I can't think of it at the current market price. That's why time has passed. Personal national qualification can be taken at company expenses Contact us from here!
