Use of safety helmets

At the power construction site, the hard hats worn by the workers are mainly to protect the head from harm. It can protect people's head from injury or reduce the degree of head injury in the following situations.

(1) When a flying or falling object hits the head;

(2) When the operator falls from a height of 2m or more;

(3) When there is a possibility of electric shock on the head;

(4) When walking or working in a low position, the head may collide with a sharp, hard object.

Safety helmets must be worn in accordance with standards, and use must comply with regulations. If it is worn and used incorrectly, it will not provide sufficient protection. Generally should pay attention to the following matters:

(1) Before wearing the helmet, adjust the rear cap adjustment belt to the proper position according to your own head type, and then fasten the elastic strap inside the cap. The elasticity of the cushioning pad is regulated by the strap. The vertical distance between the top of the head and the top of the cap body is generally

Between 25 and 50mm, it is better not to be less than 32mm at least. In this way, it can be ensured that when the impact is applied, the cap body has enough space for cushioning, and it is usually beneficial to the ventilation between the head and the cap body.

(2) Do not wear a hard hat or wear a brim behind your head. Otherwise, the protective effect of the helmet on the impact will be reduced.

(3) The lower tie of the helmet must be buckled under the jaw and fastened tightly. This will not be blown off by strong winds, or it will be touched by other obstacles, or the helmet will come off due to the back and forth swing of the head.

(4) In addition to the cap lining inside the cap body, some of the helmet heads also have small holes for ventilation. However, do not casually open the hole for ventilation during use. This will reduce the strength of the cap body.

(5) Due to the safety helmet being used, it will gradually be damaged. Therefore, it is necessary to check regularly to check for cracks, dents, cracks, and wear. If abnormalities are found, they must be replaced immediately and no further use is allowed. Any severely hit, cracked hard hat, whether or not there is any damage, should be scrapped.

(6) It is forbidden to use a safety helmet with only the lower jaw attached to the cap shell, ie a helmet with no buffer layer inside the cap.

(7) The construction personnel shall not take off the helmet, place it aside, or use it as a cushion during the on-site operation.

(8) Because the safety helmet is mostly made of high-density low-pressure polyethylene plastic, it has the properties of hardening and blemishes. So it is not easy to expose to sunlight for a long time.

(9) Newly-collared helmets first check whether there is a labor department's permission for production and product certification, and then see if there is any damage, uneven thickness, and whether the buffer layer, adjustment belt, and elastic belt are complete and effective. Does not meet the requirements of the immediate exchange.

(10) Wear safety helmets for on-site indoor work. Especially when working in the room, wear safety helmets because the helmets can not only prevent collision but also provide insulation.

(11) Peacetime helmets should be kept clean and tidy, and they must not touch the fire source. Do not apply paint on the helmet. Do not sit on a stool to prevent loss. If lost or damaged, it must be replaced or replaced immediately. No helmets are allowed to enter the construction site.
