BENEFITS OF USING A HELMET
*
*It protects the head from injury when heavy materials are thrown or fall on the head from above.
*
*It prevents accidents caused by long hair getting wrapped around the rotating part of the machine due to the effect of static electricity while working.
*Helmet is most commonly used as head protection.
STRUCTURE OF HELMETS
It is manufactured from an insulating material similar to a dome with a visor on the front, without any holes or metal parts, resistant to impact, moisture, heat, oil, water, acid, sweat and electricity, weighing not more than 450 grams as a single piece.The helmet has overhead and surrounding straps that ensure contact with the head.The girth band should be made of a soft and non-sweating material with a width of not less than 30 mm, and should also be designed to have a ventilation gap of at least 5 mm with the helmet, and should be adjustable so that people of different sizes can wear it.There should be at least 4 overhead straps and they should be firmly combined with the surrounding straps, and the distance between the inside of the helmet and the top of the head should not be less than 30 mm. The helmet should fit the head at least 8 cm and should not fall off the head while working prone. The helmet must be resistant to the breakdown voltage of 20,000 V at 50 Hz. This voltage value should never be considered as the voltage value that will provide protection to the user.
