6 self-heating hot pots that are deformed after heating
Why does self-heating hot pot have a risk of burning out?
self-heating hot pot is convenient for everyone to know. You don’t need to fire or plug in when using it. It is the "white moonlight" in the hearts of many white-collar workers and students who are inconvenient to cook and want to have a full meal.
Put all the ingredients into the inner box, pour cold water into the outer box, let the heating bag fully "suck" it, and then put the inner box in for a period of time to get a delicious and attractive hot pot.
But do you know? The heating packs in the self-heating hot pot are actually dangerous chemicals. Improper operation may cause ignition and explosion?
Self-heating convenient hot pot is mainly composed of ingredients, ingredient pot, pot lid, outer pot and heating pack. The heating principle is to use the substances in the heating pack to contact water to release heat, so that the food in the upper ingredient pot will absorb heat and the temperature will increase.
Generally, self-heating hot pot heating packages can be divided into two types: one is calcium oxide, aluminum particles, sodium bicarbonate; the other is calcium oxide, aluminum powder, sodium carbonate , and sodium hydroxide.
"China Food Safety Network" inquiry includes Dalongyi Jingdong's self-operated flagship store and Zihaiguo Zihaiguo flagship store, and many self-heating hot pot brands learned that the heating package of self-heating hot pot is composed of sodium carbonate, roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime, etc., and the main reactant is quicklime.
CaO + H2O = Ca(OH)2 As we all know, the heat emitted by the reaction of quicklime plus cold water can increase the temperature of 1L of water by 13.78℃. Generally, the amount of water placed in a self-heating hot pot is a bottle of mineral water. It can heat up by more than 90°C 20 seconds after encountering the water. A large amount of gas will also be generated during the process. Improper operation may cause an explosion.
Internet celebrity "self-heating hot pot" may cause an explosion
"I heard a 'bang' and the hot pot bowl was fried." Recently, Mr. Fang, who lives in Jing'an District, caused an explosion due to improper operation of heating the "self-heating hot pot", and the hot liquid splashed to his right eye. The doctor said that the damage would affect his vision.
Mr. Fang did not read the instructions for eating carefully. artificially blocked the air outlet of the self-heated hot pot , causing the hot pot bowl to "suffer" breath. Huge heat energy gathered in the small box and instantly exploded!
In addition, according to the Associated Press, a Chinese student was eating a self-heating hot pot in his dormitory. Because the carbon monoxide content near the heating bag was extremely high, the alarm system was triggered, and the local emergency evacuation was urgently...
The "Notice on the Test of Self-heating Convenient Hot Pot Products" issued by the Shanghai Consumer Rights Protection Committee shows that the heating bag of self-heating convenient hot pot products is dangerous to release flammable gases when exposed to water, and the product is also a dangerous cargo during transportation.
or even, you must be very careful when you throw it away after eating. The heating pack has a long heating time and may continue to heat up for a period of time after eating and throwing it away, which is also a potential hazard for scavengers and workers who sort garbage.
The most dangerous danger is that it is not aware of the danger
"China Food Safety Network" reporter randomly interviewed relevant officials in charge of major supermarkets about the sales of self-heated hot pot. The situation shows that there are still many young people who buy self-heated hot pot. In 2018, compared with 2017, people's recognition of it has gradually increased.
But in contrast, people know nothing about the dangers behind its convenience, a reporter from China Food Safety Network conducted a random street interview. The results show that more than half of the people do not think that self-heating hot pot is dangerous, one in six never read the instructions carefully, and only a small number of people will strictly avoid the taboo practices on the instructions.
"Didn't specifically avoid children."
When a reporter from "China Food Safety Network" asked whether a woman who led a two or three-year-old girl would put the self-heating hot pot in a place that her children could not reach, she shook her head and smiled, a little confused.
"Is this dangerous to the child?" then remembered something and raised his head to ask.
8-year-old boy's eyes were dissolved by alkaline liquid
For children, they do not have enough understanding of these dangerous chemicals. If parents do not pay attention to care, they will lead to a tragedy.
Recently, an eight-year-old boy put the desiccant (including quicklime) in his snack bag into a cup, but he didn't expect that it exploded shortly after it was put in. Finally, the doctor found that the child's right eye had been eroded by alkaline liquid, his entire eyeball was dissolved, he was completely blind, and he was unable to recover from any medical method.
Whether it is a quicklime desiccant or a self-heating hot pot heating pack, it is a chemical reaction that uses quicklime to add water to heat. Since such a severe chemical reaction must be a taboo. The most dangerous danger is that you are not aware of the danger. Can the outer packaging promotion of self-heating hot pot be enough to let consumers understand the risks?
According to more than 20 brands selected by the Shanghai Consumer Protection Committee, the outer packaging of the 20 samples contained relevant warning information and operating instructions. The contents of warning information ranged from 3 to nearly 10.
such as "Be careful of steam burns", "Please do not allow children to operate independently", "Only add cold water", "Please do not touch the heating pack when your hands get wet", "No direct sunlight", "If air transport is required, please use luggage to check in" and other related warning information.
However, warnings are mostly in relatively hidden locations. On the front of the self-heating hot pot bowl, there are usually delicious hot pot pictures printed. Some warnings and instructions are printed on the back of the wrapping paper, so those precautions cannot be seen at first glance.
Does self-heating package have safety risks? The company says so.
"China Food Safety Network" reporter contacted Haidilao to connect with the media docking person in self-heating hotpot and sent an interview letter, but has not received any reply so far.
But when the reporter asked Haidilao customer service about self-heating hot pot, Haidilao customer service made it clear that the heating pack would not cause ignition. Haidilao heating bags are made of safe materials for reaction, and the heating bags are also packed tightly with non-woven fabrics and will not have safety threats.
Dalongyan and Zihai Pot said that there has been no burning incidents in the heating pack at present. "Even if the air outlet is blocked, it should not burn out. The inner box may expand and deform, but it is best to operate with caution according to the instructions."
The heating pack with self-heating convenience hot pot samples with brands such as "Honglu" and "Zihai Pot" does not indicate the ingredients and the company's standard code. The reporter called the company, but has not received any reply so far.
Then the reporter interviewed six sample merchants whose pot bottoms were deformed during the evaluation of the Consumer Protection Committee.
Baicaowei customer service: "The deformation of the pot base rarely occurs, and even if the pot base is deformed, it will not burn or explode." When the reporter asked whether the deformation of the pot base is related to the material of the inner pot and whether the melting point of the inner pot is too low, the customer service said that it was unaware of it and did not answer.
Kakasha Mo Xiaoxian: "No deformation has been encountered for the time being."
Laochengnan: "The PP plastic material used in our hot pot box is high temperature resistant and has been tested for food packaging safety."
self-heating hot pot safety problems, there are no relevant national or industry standards.
Consumer Protection Committee stated that at present, regarding the safety management issues of this type of product itself and its heating packages, my country has no relevant national or industry standards.
recommends that relevant manufacturers place product safety in the most important position and eliminate product risks to the greatest extent. It is recommended that relevant competent departments initiate relevant standard-setting procedures as soon as possible to unify product safety performance requirements and risk warning content.
Notes:
Experts remind consumers that when operating " self-heating food ", they must strictly use the heating package according to the instructions, and pay attention to opening the exhaust hole during the heating process to avoid accidental damage.
If you use a glass dining table at home, it is best to add a heat insulation pad under the "self-heating food" to prevent the glass from bursting. In addition, it is strictly forbidden to carry quicklime when taking a plane, and the quicklime contained in the self-heating food heating package belongs to this category of aviation dangerous goods, so you cannot carry or consign such self-heating food when taking a plane.
