Safety Helmet: For Protecting Your Head

A safety helmet is also known as a hard hat. It is a safety equipment, which is designed to protect the head and soft tissue of the face. The safety equipment is primarily used to protect the skull from injury caused due to the impact of falling objects, debris, electrical shock, bad weather engineering materials list and other workplace hazards. A hard hat acts as a cushion and limits the impact of a falling object. It protects the wearer from serious brain injuries and head trauma. The safety equipment also protects the wearer’s neck, face and shoulders against splashes, drips and spills.
A basic safety helmet includes a rigid shell attached to a suspension system. The internal suspension system uniformly spreads the weight of the hat over the top of the head. The suspension system also creates a space of 30mm between the shell and the wearer’s head. When an object hits the helmet the impact is not directly transmitted to the skull of the wearer. A hard hat is usually very light-weight. It generally weighs below 1 lb.
Few protective accessories that come with a safety helmet are sun visor, welding mask, headlamp, flashlight, ear protectors, clips, insulation, mirror, chinstrap, face shield and hooks. The insulating side pads are installed in order to protect the wearer from electrical shock and extremely cold weather. The hooks are best cnc spindle used to hang radios, pagers, cameras and walkie talkies. These safety equipment are widely worn by archaeologists, workers at construction sites, coal mines, factory settings, diamond mines and other mining sites. These helmets are also worn by motorcyclists, cyclists, bikers, horse riders and skateboard players.
The concept of protective hats was first introduced by Edward Dickinson Bullard in 1898. E.D. Bullard was concerned about the large number of workplace accidents experienced by the miners in California. Later his son E.W. Bullard modified the safety hat and created a ‘Hard-Boiled Hat’ made of glue, steamed canvas and black paint. He patented the ‘Hard-Boiled Hat’ in 1919.
These safety helmets are made from a wide range of materials, such as fiberglass, thermoplastics, HDPE, Ultem, aluminum, steel and other durable metals. Hard hats are available in a variety of colors, including white, yellow, red, blue and green. White helmets are worn by engineers or supervisors, blue helmets are worn by technical advisors, red hats are worn by safety inspectors and green hats are worn by new workers. These safety helmets are classified as:
Class A: The ‘Class A’ helmets are designed for general use. They offer a good impact protection. These helmets offer limited protection against electric shock. These safety equipment are widely used in mining sites, building construction sites and shipbuilding factories.
Class B: These safety equipment are worn by workers engaged in electrical work. These equipment provide protection against high voltage shocks, burns and falling objects.
Class C: These safety equipment are very lightweight. They offer limited protection against electric shock or falling objects. These helmets are designed to protect workers against fixed objects.
