The skull fulfills the function of protecting the brain, the eyes, the ears. It does it well, it is resistant, but it has its limits. A small object, such as a golf ball, flying at a moderate speed that hits the skull can fracture it.
If the mass and / or speed are greater, the injuries will be more serious. In certain types of work the injuries in the skull can be very serious so it is necessary to use an element that protects it. The element designed to fulfill this function is the protective helmet for industrial use.
Formally, a safety helmet is designed to provide the user with protection from falling objects that impact on the upper part of the shell.
The degree of protection it provides is limited to compliance with the requirements of current regulations; for example:
IRAM 3620 (Argentine)
NBR 8221 ( Bra<il)
ANSI/ISEA Z89.1 (United States)
UNIT 687 (Uruguay)
EN 391 (Europe)
COMPONENTS OF A PROTECTIVE HELMET FOR INDUSTRIAL USE
The helmet is composed of a shell and a harness or suspension, components that must be designed specifically to work together.
Although the helmet is certified and fulfills the required function of protection as a whole, we can say of its components:
External cover made of thermoplastic polymer, has the function of resisting the blow and divert the object.
HARNESS or SUSPENSION
Internal part, made of thermoplastic polymer that can include textile components. It has 2 very important functions: positioning and securing the housing to the head and cushioning the impact.
The LIBUS helmet line will only fulfill its function (certified) when a LIBUS housing is mounted on a LIBUS harness (all lines)
