[Home appliances fire safety] hair dryer blowing more than ten minutes after the wet towel is burned through

After blowing for more than 20 minutes, the wet towel was blown dry and a small hole was burned.

The experimenter was placed on a hot pot heating step by step

At 4 o'clock in the afternoon the day before yesterday , a residential building near the North Huanbei Market in Hangzhou caught fire. Some people suspect that a short circuit caused by a rice cooker fire.

Then extend his thoughts: On the morning of December 1 , a fire broke out on the third floor of the dormitory of No. 172 Stadium Road, Hangzhou . Afterwards, the money reporter learned that it was a girl who forgot to turn off the hair dryer. Fortunately, no casualties were caused.

Looks like ordinary household appliances. Why did the winter become a hidden fire "landmine"?

December 15, Hangzhou Qianjiang Evening News Joint Police Fire Brigade West Lake Scenic Area Brigade (hereinafter referred to as scenic fire brigade), experiments to tell you the hidden side.

Experiment 1: How terrible is the fire caused by a hair dryer?

Props: An ordinary hair dryer, a towel

Experimental procedure: Firefighters put the hair dryer on and put it on the side of the towel

When it comes to hair dryers, people first think of its function as blowing hair. However, these days the weather was cold and the drying effect of the hair dryer came in handy.

In order to save time and quickly dry clothes, many people put wet clothing on the hair dryer and then turn on the strongest hot air. This is a very common scene in life.

In order to simulate this scenario, the staff of the scenic fire brigade specially selected an open space that was being renovated, and then bought an ordinary hair dryer from the market. Wrap it in a hair dryer with a wet towel and start blowing it with power.

At this time, Zeng Rui, a fire brigade of the scenic spot, took out a temperature gun.

At the scene, the reporter noticed that the surface temperature of the towel covering the hair dryer quickly soared to 200 degrees Celsius . After 10 minutes, the towel wrapped in the tuyere burned through two holes and was accompanied by a pungent burnt smell.

Although the experiment did not end with an imaginary fire situation, it can be proved through experiments that if the blower is not used properly, its risk factor will increase significantly.

To this end, Zeng Rui, a fire brigade of the scenic area, reminded everyone:

1. When purchasing a hair dryer, choose a regular channel, a well-known brand product, and try to buy a hair dryer that has overheat protection function (the temperature will stop automatically when it is high).

2. Do not block or cover the hair dryer when using the hair dryer.

3 , if the wire is hot or hot, turn off the switch or unplug the power immediately.

Experiment 2: Is there a safety hazard in cooking a small hot pot?

Props: A hot pot, a bottle of mineral water

The experimental process: After the firefighters use heat packs, they block the air outlets with mineral water bottles.

Recently, a so-called "lazy self boiled hot pot" in the circle of friends quietly popular, highly sought after. The safety issues arising from self-heating hotpots have also attracted everyone’s attention.

So, is there a safety hazard behind the boiled hot pot? The scenic fire brigade staff selected a hot pot from the market and used the experiment to find out.

Zeng Rui staff told reporters that the principle of self-cooking hot pot is very simple, use of sodium carbonate, roasting diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, a bag of fever, in case of cold water in 5 to 10 seconds A large amount of heat is released, the temperature can reach about 85 °C , and the lunch box rapidly expands and deforms.

However, it should be noted that if the air outlet is accidentally blocked, there is a risk of explosion. In the experiment, the firefighters tested with a temperature gun. The fever pack quickly warmed up after reaching the water, once reaching 85 degrees Celsius , and the air at the outlet also rose .

From the experimental results, self-cooked small hotpots are not as reliable as online uploads. Just follow the prompts.

Of course, Zeng Rui still wants to remind the general public that there is a vent hole in the lid of the hot pot. If the hole is blocked, it is easy to burn people, so be sure to open the vent hole to relieve pressure.

In addition, if the family is using a glass table, it is best to add a thermal pad below the self-heating food to prevent the glass from warming up and bursting.
