What to do with rusty iron nails nailed to the feet

When you step on a rusty nail, you should go to the hospital in time and under the guidance of a doctor**.

Don't think it's a minor injury, because it's because the wound is small, the bleeding is less, and the dirt can't be discharged, which is easy to cause purulent infection. The emergency treatment can be done as follows:

1.First, the nail should be pulled out, and then the blood in the wound should be squeezed out with the thumbs of both hands, or the wound should be beaten with a clean, hard wooden strip to let the bacterial dirt in the wound drain with the blood.

2.Remove sludge, rust and other substances from the wound, disinfect it locally with iodine or alcohol, and then bandage the wound with sterilized gauze. After the wound is treated, go to the hospital**.

3.If you step on a thin iron nail or needle, if the nail or needle is a broken nail or needle, do not throw it away, you can take the same nail needle to the hospital together for the doctor to judge the depth of the wound.

4.Immediately go to the hospital for tetanus antitoxin, intramuscular injection of 1500u tetanus antitoxin, timely and thorough debridement, all wounds should be debrided. For seriously polluted wounds, all necrotic and non-viable tissues should be removed, foreign bodies should be removed, ineffective cavities should be incised, wounds should be opened, and adequate drainage should be done, but sutures should not be required.

If you step on a rusty nail, it is recommended to clean the wound with hydrogen peroxide in time to avoid residual clostridium tetani in the wound, and inject tetanus as soon as possible within 24 hours.

It is recommended to go to the emergency department of a regular hospital.

You can mix baking soda and water together to make a paste, and then we will evenly spread the baking soda paste on the surface of the rusty item, remember to cover it all! After 1-2 hours, you can start brushing with a brush, and the rust is gone all at once!

Lemon and salt can also remove rust from the tool, just sprinkle a layer of salt on the surface of the rusty item, then squeeze some lemon juice and let it stand for 3 hours, after which we can remove the rust layer by wiping the rust with the skin of the lemon.

White vinegar, vinegar can have a chemical reaction with the rust on the metal, and decompose the rust, so at this time we can soak the rusty things in white vinegar, and after a few hours, the rust on it can be easily wiped off, what if the rust is too large? It's as simple as pouring white vinegar directly onto the rusty surface, and then slowly brushing it off with a brush.

Rust can be easily removed by dipping a potato skin in a small amount of salt and spreading it on the rusty area of the iron pan. Potato peels not only relieve pain and reduce swelling, but also remove tea stains from teacups.

The reason why cola can remove rust is because cola contains carbonic acid and can oxidize rust by ionic reaction, but the function of removing rust from carbon dioxide loss after a long time is relatively small, so it is necessary to use cola that has just been opened.

1. Sour vinegar method: vinegar can remove rust. It's effective. Heat the iron first and turn off the heat. Use a rag and dip some vinegar directly to wipe the rust area. Rust usually falls off right away.

2. Rice water: The decontamination effect of rice water is very strong. Soak it in a thicker rice wash for about 2-3 hours, boil the rice wash water, and rub it little by little with an iron rag during the boiling process.

3. Steel wool ball: The general stolen goods of steel wool ball can be removed.

Sanded with sandpaper, then soaked in hydrochloric acid, and finally painted. Or corundum whetstone is slowly polished.

Chemical changes. A change in the formation of a new substance is a chemical change, and in this reaction, rust is formed, and rust and iron are not the same substance. There is no new matter generated in a physical change, so it is not a physical change.

If subdivided, it is galvanic corrosion and is oxygen-absorbing corrosion. <

Rusting of iron nails is a chemical change. A change in the formation of a new substance is a chemical change, and in this reaction, rust is formed, and rust and iron are not the same substance. There is no new matter generated in a physical change, so it is not a physical change.

If subdivided, it is galvanic corrosion and is oxygen-absorbing corrosion.

Tetanus should be prevented.

If you accidentally step on a rusty iron nail, on the one hand, the wound may be contaminated by the fungus dust in the rust, and on the other hand, the hypoxic environment in the depths of the wound is conducive to the germination of tetanus spores.

When you arrive at the hospital, you first perform a thorough surgical debridement of the wound to avoid the hypoxic environment required for the growth of Clostridium tetani, and then consider whether to inject in order to further reduce the risk of tetanus.

There are actually two types of tetanus shots:

One is tetanus toxoid, which is a tetanus vaccine made of antigens;

The second is immunoglobulin, which is an antibody, which is divided into tetanus antitoxin (TAT, also known as horse break) and tetanus immune globulin (TIG, also known as human breakoutus) according to different **.

No time to be injured:

The best way to prevent tetanus is to get vaccinated, which provides immunity for up to 10 years.

Vaccination is applied to the body's immune system through antigens, and the body will produce corresponding antibodies to neutralize the neurotoxins secreted by bacteria, thereby having a protective effect on the nervous system and avoiding the onset of disease. After 3 or more doses of tetanus vaccine for three months, almost everyone is able to produce enough antibodies and can have immunity protection for up to 10 years.

How can I prevent an injury?

1.During the vaccine protection period: if the wound is shallow, small, clean, and there is no foreign body embedded in the flesh, after debridement, no injection can be given; When the wound is large, deep, and heavily contaminated, a booster shot of tetanus toxoid (aka vaccine) can be given to quickly increase antibody levels in the body.

2.Beyond vaccine protection: If the last booster was 10 years ago, a 1-shot booster dose is recommended to provide long-term protection, regardless of wound condition.

3.Not vaccinated: If you haven't had a tetanus vaccine, are incomplete, or can't remember when you got vaccinated.

Tetanus is unlikely to develop when the wound is superficial, and tetanus vaccine should be given for 3 months to promote the production of protective antibodies, after which a booster dose every 10 years is recommended. If the wound is of the type of tetanus mentioned above, immediate TAT or TIG injections are required for short-term rapid protection, along with regular tetanus vaccination for long-term protection.

It is not necessary to go to the hospital immediately for tetanus injections for any wound, whether it is necessary to inject according to the patient's autoimmune status and the type of wound, if there are enough protective antibodies, no amount of antibodies can provide much help.

It is not advisable to run to the hospital to get an immunoglobulin as soon as you get a nail in your foot or your hand is cut by a knife, not to mention the waste of medical resources, and the potential adverse effects that may be brought about by TAT injections cannot be underestimated. Of course, the debridement of the wound should not be neglected because there is a vaccine or antibody, so as to delay the disease.

Iron rusts when left for a long time. Iron is susceptible to rust, not only because of its chemical activity, but also because of external conditions. Moisture is one of the substances that makes iron rust easily. However, water alone will not make it.

Iron rusts, and only when the oxygen in the air is dissolved in the water, the oxygen reacts with the iron in the presence of water to produce something called iron oxide, which is rust. Rust is a brownish-red substance, and it is not as strong as iron.

It is hard and easy to fall off, and after a piece of iron is completely rusted, the volume can expand by 8 times. If the rust is not removed, the spongy rust is particularly easy to absorb water, and the iron will rot faster.

To remove rust, you can be.

Shovel it off with various tools, or soak it in an acidic solution to dissolve it. After removing the rust, the surface of the iron must be treated, coated with a layer of lead, and then painted; Or plating something else that is not easy to rust.

of metal. A more radical approach is to add some other metals to the iron to make a stainless alloy. The stainless steel we are familiar with is an alloy made by adding a little nickel and chromium to the steel.

Iron nails will rust in damp and dark places, when iron and oxygen react, and the iron oxide produced is rust, and iron nails are not easy to rust in dry places. Iron nails, with a flat head at one end and a sharp end at the other, mainly play a fixed or connecting role. <

Mineral oil or paint: Applying mineral oil or paint to iron nails has the disadvantage that the paint is not easy to clean when it is used later. Anti-rust paper:

It is used for the packaging, transportation and storage of small iron or non-metallic parts; Specific operation: Wrap the nails in anti-rust paper and store them in a dry environment. Anti-rust film: Spray a layer of wax protective film on the metal surface, wash it with hot water and wipe it dry when you use it.

1. Mineral oil or paint.

Coating the surface of iron products with mineral oil, paint, firing enamel, spraying plastic, etc. The specific operation is to apply mineral oil or paint to the nails, and the disadvantage is that the paint is not easy to clean when it is used later.

2. Anti-rust paper.

Anti-rust paper is an economical and environmentally friendly anti-rust packaging material, which is used for the packaging, transportation and storage of iron or non-metallic parts with small volume; The anti-rust effect is relatively fast and simple to use. It has the best moisture-proof, anti-rust and anti-corrosion functions. It also has the characteristics of long anti-rust time, safe use, beautiful packaging and low cost.

Specific operation: Wrap the nails in anti-rust paper and store them in a dry environment.

3. Anti-rust film.

Wax spraying is to spray a layer of wax protective film on the metal surface to isolate the metal surface from moisture, so as to achieve the purpose of rust prevention. The specific operation of the surface of the iron nail is sprayed with a layer of wax protective film, and it can be cleaned and wiped dry with hot water when used, which is a safe and environmentally friendly disposable anti-rust material.

In addition, it is necessary to pay attention to the dryness of the storage environment of the iron nails, and the humidity should not be higher than 50.
