At more than 2pm on July 14, Mr. Tang, who lives in Gudi Shi, Xiamen, accidentally fell off the window sill while collecting clothes. His girlfriend Ms. Zheng also fell from the fourth floor to save her boyfriend. The two were seriously injured. Mr. Tang Unconscious. More unfortunately than that, at 17:40 on the 15th, a tragedy occurred in Chenmendou Community, Licheng District, Putian City, Fujian Province: a 4-year-old girl was careless while playing on a balcony on the 17th floor of Building No. 12 in the community Fell; the 10-year-old sister on the side wanted to reach out and grab the sister, and then fell; at that moment, the father rushed to the balcony, trying to grab the child, maybe it was too rushed too fast, not only did he not grasp the two children, I also fell from the balcony, and the father and daughter died on the spot, which is really heartbreaking.
There are many similarities in the time of these two crashes. One is that the safety precautions of the two are not strong enough. As a child, it is the responsibility of the parents to take care of it improperly. As an adult, the dangerous behavior of climbing on the anti-theft window has never been known, and eventually caused this disaster. The second is that the installation of the safety nets of the two safety nets is not standardized. The safety nets have strict requirements for safety equipment, and the height and spacing are clearly defined. The third is the improper rescue method. In these two accidents, it was the tragedy that the rescuer also followed the crash after a party fell, which was caused by the lack of scientific rescue methods.
safety consciousness
In fact, there are many reasons for the fall, especially the occurrence of children ’s falling accidents. Eighty percent of the children who fell into the house lacked protective barriers, which caused the children to climb up the window sill. Part of the reason was that the parents left the children alone at home and the children were anxious What happened after the unrest. Therefore, parents should always pay attention to the movements of their children and strengthen safety protection. Especially for children 2-6 years old, children are most likely to run around at this time, and there is no self-consciousness, so parents need to pay more attention.
Guardrail
Guardrails play an important role in safety precautions, but they also have many requirements, and improper installation can also be dangerous.
First of all, the protective window must choose the stainless steel protective window. The protective window made of stainless steel can be used for a long time without rusting. No one wants to see the protective window installed by themselves will be rusty after three or five years, which is also the consumer The most basic needs.
About the selection of stainless steel protective windows:
First, whether the stainless steel pipes meet national standards.
The national standard of stainless steel pipe requires that the stainless steel pipe must contain a certain amount of nickel and chromium, so as to ensure that the stainless steel is not rusted, and the price of inferior stainless steel pipes with low nickel content is only half of the national standard stainless steel pipes, but in terms of rust prevention and robustness Far worse than the national standard stainless steel pipe. Since stainless steels are generally not marked on the market, it is difficult to judge the quality of stainless steel. Therefore, many small processing households on the market use inferior stainless steel pipes to impersonate good quality stainless steel. This is a non-national standard trap.
Second, whether the stainless steel pipe is thick.
The thickness of the stainless steel pipe also determines the pressure resistance and sturdiness of the anti-theft window. Naturally, the thicker the pipe is, the stronger it is, and the difference in thickness is 0.1mm. The compression capacity is different by hundreds of kilograms. And every 0.1mm less thickness, the cost per square meter will be reduced by 20-30 yuan. Generally speaking, the strength of anti-theft windows with a thickness of 0.6mm to 0.8mm is sufficient, but the reason why so many protective windows are broken is that many small processing users on the market pretend to be 0.6mm with some 0.4mm pipes And 0.8mm pipe deceives consumers, and this is the false trap.
Although there is no explicit provision on the installation of anti-theft windows, it is determined in principle in the "Civil Law" that the installation of attachments outside the wall cannot affect the rest and safety of others, that is to say, the installation of the anti-theft window must be attached to the external wall Strict, can not be exceeded to cause easy climbing, causing hidden dangers to the residents upstairs.
The installation of the anti-theft network is usually completed by the anti-theft network provider. Therefore, when selecting the anti-theft network, you must choose a merchant with quality assurance. The installation should be done by a professional installer. In the installation of the anti-theft network, we must pay attention to the safety of electricity and life safety during the installation process, especially when installing high-rise buildings. In the anti-theft network installation, some manufacturers or residents may cut corners on materials in order to reduce costs. This is not feasible. Both merchants and users must install according to standards.
There is also a lot of knowledge in installing anti-theft net railings, and there are hidden safety risks if the spacing is too wide. Judging from the “Residential Design Code†issued by the Ministry of Housing and Urban-Rural Development on August 1, 2012: the balcony railing should be designed to prevent children from climbing, and the vertical distance between the vertical bars of the railing should not be greater than 11 cm. The spacing of the anti-theft net railing should be smaller than the side of the child, that is, the width from the hip to the abdomen, preferably within 5 cm, and the minimum should be controlled at about 10 cm. The spacing of the invisible anti-theft net should be slightly closer. In addition, after the invisible protection net is installed for a period of time, the steel wire may gradually loosen. At this time, if the child tries to break it, the distance between the invisible protection wire will be widened, which is very dangerous, so pay attention to regular inspections.
Fall rescue
In the event of a crash, the rescuer must first remain calm and do not panic. Judging from these two deliberate intentions, the tragedy of the rescuer falling together is related to the panic behavior of the person involved. The second is to do everything within our power and adopt a more scientific and safe approach. The little girl ’s sister is obviously not strong enough to catch her sister. In some accidents of falling from the building, someone has to pick up the fallen child with bare hands, leading to injury. Even so , The child may still be affected by a huge shock wave and cause danger. Therefore, scientific and reasonable rescue methods are also essential.
What are food additives?
Substances that are added to food to maintain or improve the safety, freshness, taste, texture, or appearance of food are known as food additives. Some food additives have been in use for centuries for preservation – such as salt (in meats such as bacon or dried fish), sugar (in marmalade), or sulfur dioxide (in wine).
Many different food additives have been developed over time to meet the needs of food production, as making food on a large scale is very different from making them on a small scale at home. Additives are needed to ensure processed food remains safe and in good condition throughout its journey from factories or industrial kitchens, during transportation to warehouses and shops, and finally to consumers.
The use of food additives is only justified when their use has a technological need, does not mislead consumers, and serves a well-defined technological function, such as to preserve the nutritional quality of the food or enhance the stability of the food.
Food additives can be derived from plants, animals, or minerals, or they can be synthetic. They are added intentionally to food to perform certain technological purposes which consumers often take for granted. There are several thousand food additives used, all of which are designed to do a specific job in making food safer or more appealing. WHO, together with FAO, groups food additives into 3 broad categories based on their function.
Flavouring agents
Flavouring agents – which are added to food to improve aroma or taste – make up the greatest number of additives used in foods. There are hundreds of varieties of flavourings used in a wide variety of foods, from confectionery and soft drinks to cereal, cake, and yoghurt. Natural flavouring agents include nut, fruit and spice blends, as well as those derived from vegetables and wine. In addition, there are flavourings that imitate natural flavours.
Enzyme preparations
Enzyme preparations are a type of additive that may or may not end up in the final food product. Enzymes are naturally-occurring proteins that boost biochemical reactions by breaking down larger molecules into their smaller building blocks. They can be obtained by extraction from plants or animal products or from micro-organisms such as bacteria and are used as alternatives to chemical-based technology. They are mainly used in baking (to improve the dough), for manufacturing fruit juices (to increase yields), in wine making and brewing (to improve fermentation), as well as in cheese manufacturing (to improve curd formation).
Other additives
Other food additives are used for a variety of reasons, such as preservation, colouring, and sweetening. They are added when food is prepared, packaged, transported, or stored, and they eventually become a component of the food.
Preservatives can slow decomposition caused by mould, air, bacteria, or yeast. In addition to maintaining the quality of the food, preservatives help control contamination that can cause foodborne illness, including life-threatening botulism.
Colouring is added to food to replace colours lost during preparation, or to make food look more attractive.
Non-sugar sweeteners are often used as an alternative to sugar because they contribute fewer or no calories when added to food.
What are feed additives?
According to the European Commission's commonly accepted definition,
Feed additives are products used in animal nutrition for purposes of improving the quality of feed and the quality of food from animal origin, or to improve the animals` performance and health, e.g. providing enhanced digestibility of the feed materials."
You thought that animals ate plants, or grass or some other `food` natural to their ilk. But in reality, in today`s factory farms, feeding livestock is a complicated endeavor fraught with controversy and split opinions.
According to a 2010 report by MarketsandMarkets, a market research company, the global feed additives market is expected to reach $18.7 billion by 2016. That`s no small industry.
There are four general types of feed additives:
- Sensory Additives – these stimulate an animals appetite so that they naturally want to eat more.
- Nutritional Additives – these provide a particular nutrient that may be deficient in an animal`s diet.
- Zootechnical Additive – these improve the overall nutritional value of an animal`s diet through additives in the feed.
- Coccidiostats and Histomonostats – these are feed additives which are antibiotics, intended to kill or inhibit protozoa (bacteria/micro-organisms). These have been banned in Europe since 2009 and replaced with probiotic alternatives.
