What is a hard hat?
Hard hat is a piece of safety equipment that is designed to protect the skull and soft tissue of the face. Hard hats are required on most construction sites, where workers are threatened by injuries by falling objects, electric shock, falls, spraying and a number of other risks in the workplace. Although the hard hat was introduced only at the beginning of the twentieth century, it quickly became the required equipment on the site of work and hard hats saved the unspeakable number of lives, because the first "hard hat" was introduced in 1919. Bullard, a pioneer in the field of safety in the workplace feared by a large number of catastrophic accidents experienced by miners in California. He wanted to specify the soft leather hats worn by miners, and developed a hat made of a solid stewed canvas stretched through a suspension system that picked up the hat out of his head. The hat was known as a hard hat for the manufacturing process, and was covered with black color before sending for sale.
The concept of head wear quickly captured the head and the first official area of the hard hat in the United States was on the site of the Golden Gate Bridge bridge, which was opened in 1937 for great recognition; Partly due to the low occurrence of injuries and death during the construction of the bridge. The Hoover Dam workers also wore hard hats and in 1938 E.D. Bullard Company made the first metal derogatory hat, followed with a version of glass fibers at the age of 40. These materials were stronger, more resistant and more protective and the injury in the workplace was significantly reduced.
In the 50th and 60s. Thermoplasty has become more accessible than metal or fibrous glass and a light, robust plastic cap was born. Bullard Company was the first to use the injection bar to create solid hats and continued the innovative suspension suspension to support a fixed hat on the head while ensuring that in the case of NENOdy will not slip or fail. In the 1980s, Bullard Company developed specialized solid hats for emergency staff, climbers and others that need light, robust protective heads.
The basic fixed hat has a slight weight, a solid shell connected to the internal suspension system that keeps the hard hat snuggle on the head. Some patterns also integrate pupils to overshadow eyes, welding masks, clips for lamps and insulation that protects from electric impact. Many also integrate ear protection space, another frequent requirement in the workplace. When wearing properly, a solid hat protects the skull and a soft facial tissue and are required on most jobs for all individuals, even for those who simply visit the risk of injury related to the structure.
Classically they come in white or adjacent, but rarely remain a long firm color. WellThe construction workers decorate their helmets with stickers reminiscent of jobs and trade union membership, partly to help distinguish which tough hat belongs to whom. The hard hat became part of the iconic image of an American construction worker due to his ubiquitous presence at the site of work and the term "hard hat" is sometimes used in slang to refer to construction workers.
