First, understand the work environment:

The first step in choosing a helmet is to understand the work environment and its hazards and determine if you need to wear one. In general, you need to wear a helmet to protect your health when the following work environments and their hazards occur.

1. the presence of acid and alkali conditions.

2. Low and cold temperatures.

3. Hot and flammable situations.

4. Where landslides occur.

5. Where landslides occur.

6. The existence of debris splash situation.

7. Where there are bumps and scrapes.

8. There is a falling object situation.

9. There is a collision situation.

10. There are conductive and static electricity.

Second, choose the right helmet:

There are many kinds of helmets on the market, with different functions, styles, materials and colors:

First, the choice of function:

For the right helmet, the first thing is to match its function.

The function of helmet is divided into two aspects, on the one hand, the basic function, on the other hand, the special function.

1. Basic performance: impact absorption, puncture resistance, jaw band strength.

   
   

2. Special performance: flame retardant, lateral rigidity, low temperature resistance, extreme high temperature resistance, electrical insulation, anti-static properties, resistance to molten metal splash.

Safety helmets with basic technical properties can be used in working environments where there are hazards of falling objects, splintering debris, collisions, punctures, crushes, drops and falls.

Flame-retardant helmets are available for short-term exposure to flames, short-term localized exposure to hot objects, or exposure to hot workplaces with flammable substances.

Lateral rigid helmets may be selected where lateral crushing will occur, including where landslides and slides may occur, where foreseeable overturning objects and low-speed collisions may occur, such as tunnels and mines.

When the helmet is highly sensitive to static electricity, possible explosion or discharging is not allowed, you can choose the helmet with anti-static properties, such as precision instrument processing, petrochemical, coal mining and other industries.

When you need to contact with three-phase alternating current and electrically charged operations below 400V, such as electric power and water conservancy industries, you can choose helmets with electrical insulation properties.

When the working environment is low and the ambient temperature is not less than -20℃, such as refrigeration, forestry, etc., you can choose low temperature resistant helmet.

Second, the choice of style:

There are various styles of safety helmets, and different styles have their own safety focus.

Therefore, they are suitable for different industries and have different effects.

Therefore, when choosing a helmet, we should also pay attention to the choice of style.

When there may be splashing water, spattering slag, direct sunlight and bright light to the eyes, you should choose a helmet with a large side and tongue. When the working environment is narrow, you should choose a helmet with a smaller rim. If there is a slight need for waterproofing, choose a helmet with a crimped construction with a small rim.

When there are other hazards or special needs in the working environment, suppliers can be asked to add eye and face protection, ear protection, active cooling devices, electric induction devices, neck protection, lighting devices, warning signs and other accessories, as well as additional corporate logos, personnel or number information.

Third, the choice of materials:

Each material of the helmet has its advantages and disadvantages, and its application environment is different.

As for which helmet to choose, the editors suggest that you have a brief understanding of helmet materials and then choose according to the corresponding application environment.

ABS: It has the advantages of heat resistance, high surface hardness, dimensional stability and good chemical resistance.

It also has good electrical insulation and impact resistance.

HDPE: not only has high surface hardness and good heat resistance, but also has good electrical insulation and dimensional stability, and poor compressive strength.

PC: It has high impact resistance, high dimensional stability, good electrical insulation and high temperature resistance, but it is not cost-effective.

FRP: With heat resistance and good electrical insulation, as well as excellent acid and water resistance, flame retardancy, small deformation, etc., it has been widely accepted.

Other materials: In China, there are other helmet materials, such as adhesive tape, bamboo weaving, rattan willow, aluminum and other materials.

Fourth, the choice of color:

Regarding the choice of safety helmet color is also quite a delicate matter, for example, when the light of the operating environment is insufficient, it is necessary to choose the safety helmet with bright color; if the visibility of the operating environment is low, it should be used with the safety helmet with a large difference in the color of the environment or increase the reflective strips on the helmet in line with the requirements.

In addition, it is also necessary to give full consideration to the role and association of color from the perspective of safety, physiology and psychology, such as entering the hazardous area personnel with yellow, ordinary area personnel with white, management personnel with blue, safety management personnel with red, contractors with orange, suppliers, visitors, internships, etc. with other colors, and different personnel with different color helmets.

Finally, choose a helmet that works:

By understanding the dangers of the workplace, selecting the corresponding function, style, material and color of the helmet, you need to judge whether the helmet can be used or not, the criteria for judging are probably as follows:

1, in line with the national standard GB2811-2007;

2, the manufacturer's license is complete, with relevant qualifications;

3, the appearance of the helmet without abnormalities, and accessories complete without quality defects;

4, in the use of the period.

The above is the selection process of the helmet of the protective supplies small knowledge, Zhengzhou JiaDun Protective Products Factory is the director of the China Labor Protection Industry Enterprise Association, is the national designated labor protection supplies production enterprises.
