To prevent accidents at various industries, construction sites and other places associated with danger, workers are required to wear special helmets. They are intended for the head to protect against injury. There is a requirement that must be met in hazardous and hazardous work. When working in such conditions, workers are required to provide a personal protective equipment such as a Kevlar helmet. Let us consider in more detail this element and the material from which it is made.
What is kevlar?
First you need to figure out what Kevlar is, and consider its properties and features. Kevlar is a special synthetic fiber that is made to replace steel. This material is widely used in the manufacture of body armor, protective head helmets and car tires. The material has high mechanical strength. They produce it of different brands with a strength of 280 to 550 kg / mm 2 and a density of 1400 to 1500 kg / m 3 . It can also be used in the manufacture of cables. Kevlar in this case is located along its entire length. This prevents over-stretching and tearing of the cable itself. Kevlar helmet is made using a special thread.
In its actions, it is comparable to a web: it delays a
strong blow and prevents it from reaching a person’s head.
Kevlar thread and its application
A thread is a derivative of Kevlar. As mentioned above, it is used in the manufacture of personal protective equipment, for example, such as a protective helmet. Its application does not end there. Kevlar thread is used in shipbuilding. It is added to the bow of the ship’s hull and for processing its seams, which prevents its depressurization and flooding. Kevlar helmet is made of just such threads.
Such personal protective equipment is lightweight and does not feel at all when worn. They are highly resistant to hot sparks and metal, this value reaches 155 degrees. A material such as Kevlar helps protect a worker from
electric shock. The material can withstand any concentrated acids and abrasives. For better protection of a person, such a helmet is not subject to lateral fractures. Due to its positive characteristics, Kevlar thread is used in various industries. The only drawback of these materials is their high cost. But here industries should choose between economy and safety.
The quality of Russian production
Russian Kevlar helmet issued for sale on the territory of our state. Helmets manufactured meet all safety standards and standards. This helmet is used to protect against falling heavy materials, strong moisture, sparks from welding and various acids, high temperature.
It is used in national economic complexes, oil and gas processing, and on construction sites of the Russian Federation. Kevlar helmet of our production is no different from foreign counterparts.
Kevlar Safety Helmet
Kevlar is used not only for the manufacture of personal protective equipment in industries with harmful and dangerous working conditions, but also in the arsenal of the army. A Kevlar helmet is designed to protect soldiers from bullets and grenade fragments. It has some features:
- The helmet is made of two components: the body and stiffeners, which fit tightly on the head.
- The helmet body is protected by threads made of Kevlar material.
- High characteristics of the helmet are stored in the temperature range from -50 to +50 degrees.
- It does not interfere with driving vehicles without closing the view.
- The helmet allows for military operations in areas with high gas contamination.
- Does not distort sounds.
- If the integrity of the helmet is destroyed, it can be easily repaired in the field.
- Simplicity of design does not require additional technical equipment and repair.
- The helmet has high shatter resistance, even with multiple hits.
- It can be worn without taking off during the day. Soldiers do not appear diaper rash or calluses.
- Such a tool can be quickly put on if necessary and can be easily removed.
- If the helmet is used in winter, then a warm cap comforter is provided for it.
- Such features help maintain the life and health of soldiers.
Hands in control
For the safety of hands in industries with harmful and dangerous working conditions, special protective gloves from Kevlar are used. This personal protective equipment ensures that a person is absolutely protected from the aggressive environment. They are able to withstand cuts of any complexity. Kevlar gloves differ in a number of the following advantages:
- Gloves are able to protect against glass fragments.
- For a short period of time, they can protect against hot metal and fire.
- Used in fire ammunition.
- Seamless kevlar gloves protect against cuts with sheet metal and any other sharp objects.
- Such protective properties are found in gloves in which the skin of the hands breathes. They are convenient to work with small parts.
- Gloves serve for a long time, without being erased and maintaining the integrity of the material.
- Great for working at home, for example, drag a hot brazier, collect splinters or hot coal.
Conclusion
Having examined in detail such material as Kevlar, we can conclude that this is the most versatile material. Lightness and durability allow daily use of Kevlar personal protective equipment for the preservation of life and health.
