A helmet is a protective device that protects the head from impact. It consists of a cap shell, a cap liner, a lower cheek band and a rear cuff. The cap is hemispherical, strong, smooth and flexible, and the impact and puncture kinetic energy of the striker is mainly absorbed by the cap.
The weight of a helmet is:
a. Small edge, crimping helmets shall not exceed 430g (excluding accessories).
b. The large edge helmet does not exceed 460g (excluding accessories).
c. The cold hat does not exceed 690g (excluding accessories).
The specifications for the use of helmets are:
1. On the construction site of electric power construction, the helmets worn by the workers are mainly to protect the head from harm. It protects the person's head from injury or reduces head injury in the following situations.
(1) When an object flying or falling hits the head;
(2) When the operator falls from a height of 2 m or more;
(3) When there is a possibility of electric shock to the head;
(4) When walking or working in a low position, the head may collide with a sharp, hard object.
Second, the wearing of the helmet should meet the standards, and the use must comply with the regulations. If it is worn and used incorrectly, it will not provide adequate protection. Generally note the following:
(1) Before wearing the helmet, adjust the rear cap adjustment belt to the appropriate position according to your head shape, and then fasten the elastic band inside the cap. The tightness of the cushion pad is adjusted by the belt, and the vertical distance between the top of the person's head and the top of the cap body is generally between 25 and 50 mm, at least not less than 32 mm. This will ensure that when the impact is encountered, the cap has enough space for cushioning, and it is also convenient for ventilation between the head and the cap.
(2) Do not wear the helmet or wear the brim behind the head. Otherwise, it will reduce the protective effect of the helmet on the impact.
(3) The lower tie of the helmet must be fastened under the jaw and fastened, and the tightness should be moderate. This will not be blown off by the strong wind, or it will be knocked off by other obstacles, or the helmet will fall off due to the back and forth swinging of the head.
