In 1997, the American National Standards Institute (ANSI) revised its performance standards for hard hats. Conformity to these standards and regulation are not necessary but most all manufactures comply so they can label that they are under compliance with the standards needed. For example, a type one hard hat provides impact protection from vertically falling objects which will land on the top of the head. A type two hard hat protects from vertical and horizontal threats. There are also standards for electrical use in hard hats, which protect the wearer from electrical current. ANSI also has compliance for hard hats and their combustibility or flammability criteria.
Not only do manufactures meet the standards but they also designate a specific line of instructions for caring for your hard hat. There is an appointed handbook/booklet that outlines how to inspect for damage and how to properly fit the hat to your head. Also, even if a hard hat is properly inspected and cared for, it should be replaced after five years of use.
A very important date in hard hat history is 1933; the year construction began on the Golden Gate Bridge in San Francisco, California. This was the first construction site in history which required all employees to wear hard hats. This was because of the project chief engineer, Joseph Strauss. He wanted the workplace to be as safe as possible hence why he place safety nets and required hard hats while on the job site. Strauss also asked Bullard to create a hard hat to protect workers who do sandblasting. Bullard came up with a design covering the workers face with a vision window and a pump to bring fresh air into the mask. As time progressed around 1938 aluminum became a standard for head protection except in electrical applications. Then in the 1940’s fiberglass became the popular material of hard hats, but then a decade later thermoplastics would take over because they were easy to mold and shape with applied heat. Today hard hats are made from a material called High-Density Polyethylene (HDPE) and a type two hard hat is required to have a foam inner liner of Expanded Polystyrene (EPS).
As the industry advanced hard hats took on a technical turn with decorative adaptations and accessories which could simply clip on. ANSI, in 1997, allowed the development of a ventilated hard hat to keep wearers cooler. The sophistication provided the ability to add accessories like face shields, sun visors, ear muffs, and perspiration absorbing cloths which line the hats. The most recent improvement was attachments for radios, walkie-talkies, pagers, and cameras.
