The Correct Use of Safety Helmets and Protection


This article popularized the helmet related knowledge, introduced the different color helmet applicable people, helmet correct use method and the use of expired helmet processing problems, for the actual work with certain help.

Applicable People

The common colors of safety helmets are white, red, yellow and blue.


1.White helmet in the construction site mainly by the project supervisor or Party A to wear, their work is mostly to supervise the quality of the project and the implementation of the plan.

2.Red helmet wearing a red helmet crowd is more complex, according to the use of different habits and construction units, in the construction site mainly by the technical staff, management personnel, party A, and foreign guests to wear.

3.Blue helmet in the construction site wearing blue helmet people usually for technical personnel, work is more directional, and work with certain technical content.

4.Yellow helmet the yellow helmet is the most common in all major construction sites, the main wearing crowd is ordinary workers.

In the construction site, the correct wear of different colors of helmets is to better distinguish staff, so as not to cause unnecessary trouble.

Method Of Application


Safety cap by the liner, cap shell, jaw belt, and other accessories. 1. cap shell by the shell, cap tongue, brim, top band, etc.; 2. cap liner is the general name of the internal parts of the cap shell, by the cap band, sweatband, lining belt, and buffer device, etc.; 3. jaw belt is tied to the chin, play a fixed role in the band, by the tie and locking card composition.

1.In the use of helmets before, absolutely can not forget the point is to check in detail whether there is a helmet affects the performance of obvious defects, such as cracks, bruising traces, bump uneven, etc., wear should be scrapped helmet will bring great hidden danger, protection role will not be guaranteed.

2.In the use of helmets, one must pay attention to the helmet can not be skewed, or slack, which will have the risk of falling off. The correct practice is to wear firm wear right after tightening the jaw band, and adjust a good back hoop.

3.Can not arbitrarily disassemble or add helmet accessories, most likely to affect the original protective performance.

4.The size of the cap liner can not be arbitrarily adjusted. The internal size of the helmet (such as vertical spacing, wearing height, and horizontal spacing) directly affects the protective performance of the helmet, when the internal size changes, once the impact of falling objects occurs, the helmet will not be worn because of the impact of touching the top and not play a protective role, directly injuring the wearer. Cushion liner elasticity by the band adjustment, the top of the human head, and the top of the cap body space should be at least 32 mm to use.

Exepired Helmet

1.Different materials of the helmet validity length is different, according to the national standard GB2811 provisions, from the manufacturing completion date, the validity of plastic helmet not more than two and a half years, the validity of glass fiber reinforced plastic helmet not more than three and a half years.

2.Because of the helmet material problem, acid or alkaline substances may cause deterioration, high temperature sunlight environment will also accelerate the helmet aging thus affecting the protective performance, so the helmet in the unused period to pay attention to storage problems.

3. Safety helmet after the expiration of the need for random testing. Only the test qualified helmet can continue to use, and thereafter every year to carry out a random inspection, if the random inspection results failed, the batch of helmets need to be scrapped.

In line with the principle of safety first, continued use of expired helmets is not recommended. According to the use of different environments, the degree of wear and tear of helmets also have differences, the above introduction is not necessarily applicable to all industries using helmets.
