Will hydrogen be released when heated from a hot pot? Even after eating, it can explode.

In recent years, self-heating
hot pot
become a best-selling
food
. It is both hot pot delicious and
convenience food
fast, by the
consumers
love. However,
investigation
found that this self-heating pot although delicious and fast, but before eating or "take it easy."
heating pack to produce hydrogen triggered alarm manufacturers said there is no danger
many consumers online reflect that the use of spontaneous hot pot often triggered alarm alarm.
after the heat pack and water reaction, what substances are produced, so that the gas alarm continues to alarm? The head of the heat packet manufacturer said that when the heat packet heats up, a trace amount of hydrogen is produced, which causes the smoke sensor to appear alarm.
is a flammable and reductive gas, pure hydrogen burns quietly in the air, and non-pure hydrogen can explode when burned. In this regard, the head of the factory said there is absolutely no danger.
head of the heat packet manufacturer: "It doesn'
, if it's dangerous, it can't be that hot in the market." You don't have to think so dangerously, these big businesses do it every day.
the release of hydrogen can cause combustion explosion confined space, public places are hidden dangers
Then, the heat package after the water reaction is there a safety hazard? Not long ago, the Shanghai Consumer Rights Protection Commission reported on the testing of 20 self-heating convenience hot pot products. The test results showed that the heat packets tested were "substances or mixtures that release flammable gases in water".
experts explain that if the amount of hydrogen released after the heat packet reaction is at the combustion limit of hydrogen in the environment, i.e. the proportion of hydrogen in the air reaches between 4% and 75.6%, there is a risk of detonation. Experts also stress that similar risks can exist in confined or semi-confined spaces, such as cars.
self-heating food may pose a safety risk when used not only in confined spaces. In some public places, intensive and extensive use, there are also great security risks.
Qiuping, assistant director of the National Chemical Safety Quality Inspection Center, said:
For example, during the long-distance bus (driving), air conditioning is on in summer, the trunk is a closed environment. Heavy use of self-heating pots can lead to hydrogen build-up. If the lower explosion concentration is reached, a fire source, such as static electricity on the body, or a spark in the circuit, is sufficient to cause a burst accident.
there are still security risks after using discarded heat packets
Since the heating package and water do not need to be reacted with the help of any other substance, hydrogen is produced when the heating packet is not fully reacted to.
if the heat is wrapped in the trash can, in the face of rainy days, rain into the trash can, it will react to produce hydrogen. A trash can is a semi-enclosed environment where there is a risk of explosion or combustion if a source of fire, such as a cigarette butt, is thrown in.
the Shanghai Consumer Protection Commission this test, also reflected 20 sample heat packets again immersed in water. The results showed that the heat packets of 14 samples showed different degrees of continuous degassing. Reactions last more than 3 minutes and can last up to 8 minutes.Civil aviation is completely prohibited from carrying spontaneous heat products Guangxi is prohibited from using
precisely because self-heating products may bring many unknown risks, at present, China's civil aviation system has been completely prohibited from carrying spontaneous heat products on board the aircraft. Not long ago, Guangxi issued the railway safety regulations also clearly stipulated that the use of their own heated food on the train is prohibited.
security alerts to be standardized Safety standards need to be issued
In fact, this unpredictable but possible security risk requires a clear reminder before the user can use them. However, the reporter found that the current market does not have a spontaneous heat products for these issues made a clear warning.
this, the Shanghai Consumer Protection Commission is coordinating the relevant professional institutions to carry out safety assessment and research on this emerging products, as soon as possible the introduction of relevant standards or norms, so that consumers better and safer use of self-heating pot products.
