The hard hat was invented in 1919 by Edward W. Bullard, a young lieutenant in the U.S. Army during World War I. Inspired by the helmet he wore in the war, Bullard created the first Hard-Boiled Hat made of steamed canvas, glue, leather, shellac, and black paint. This early hard hat was soon followed by a version featuring an internal suspension system, resembling the steel M1917 Brodie military helmet. In the 1950s, the industry transitioned to thermoplastics, which were easier to mould and less costly to produce. Today, hard hats continue to evolve with new safety features and accessories, such as sweat bands, rain gutters, and advanced suspension systems.

What You'll Learn
The first plastic hard hats were made from Bakelite
The history of the hard hat can be traced back to the early years of the shipbuilding and mining industries. Workers in these industries would cover their hats with pitch (tar) to protect themselves from falling objects. In 1919, Edward W. Bullard, inspired by the steel helmet he brought home from World War I, developed the first commercially available head protection device, the "Hard-Boiled Hat", made of steamed canvas, leather, glue, and black paint.
Bullard's company, E.D. Bullard Co., soon began creating new versions of the hat with adaptations for different uses. One such adaptation was a hat made of Bakelite, an early form of plastic that was durable enough for rough labour. Bakelite was an ideal material for hard hats as it could withstand high temperatures, radiant heat loads, and sudden impacts, while remaining lightweight and safe around high-voltage electricity.
The MSA Skullgard Helmet, introduced in 1930, was made of a Bakelite resin reinforced with wire screen and linen. This helmet could withstand temperatures up to 350 °F (177 °C) without burning the wearer and was safe for use in high-heat, high-voltage environments. The Skullgard Helmet is still manufactured today, along with a low-crown version for coal miners known as the Comfo-Cap Headgear.
In the 1950s, hard hats began to be made from moulded thermoplastics, which were easier to shape and less costly to produce. Today, most hard hats are made from HDPE (high-density polyethylene), a strong, durable, and flexible plastic that offers excellent impact resistance and performs well when exposed to chemicals.

Early plastic hard hats were designed for miners
The history of the hard hat can be traced back to the early years of the shipbuilding industry, when dock workers in constant danger of being struck on the head by falling objects would harden their hats with pitch (tar). In 1898, Edward Dickinson Bullard, a veteran of the industrial safety business, founded the E.D. Bullard Company, a mining equipment firm in California that sold protective hats made of leather.
Bullard's son, E.W. Bullard, returned from World War I with a steel helmet, which inspired him to develop a safety hat for peacetime workers. In 1919, he patented the "Hard-Boiled Hat", made of steamed canvas, glue, leather, shellac, and black paint. This was the first commercially available head protection device. The U.S. Navy soon commissioned Bullard to create a similar protective cap for shipyard workers, which led to the widespread use of hard hats.
Bullard's early hard hats were designed to withstand the rigors of roughneck labour in mines. He created a version with a device to hold carbide lamps, allowing miners to find their way through dark underground tunnels. He also developed a hat made of Bakelite, an early form of plastic that was lightweight yet sturdy enough to withstand the harsh conditions of mining.
Today, mining hard hats are designed to protect workers in the hazardous and demanding conditions of the mining industry. They are made of lightweight, tough polycarbonate plastic, providing protection from top impacts and meeting safety standards for head protection in mining and other industries.

Plastic hard hats were first mass-produced in 1952
The history of the hard hat is a long and fascinating one. In the early days of shipbuilding and mining, workers would cover their hats with pitch (tar) and let them cure in the sun to harden, providing some protection against head injuries. The first industrial hard hats went into mass production in the 1920s and were made from steamed canvas, black paint, glue, and leather brims. These were widely used in shipyards and other industrial settings. However, it was not until 1952 that plastic hard hats were first mass-produced.
The E.D. Bullard Company, founded by Edward Dickinson Bullard in 1898, was a mining equipment firm that supplied headlamps, carbide lamps, and other mining equipment to miners in California, Arizona, and Nevada. Edward's son, Edward W. Bullard, served as a lieutenant in the U.S. Army during World War I and witnessed the effectiveness of helmets in protecting soldiers. Inspired by his wartime experiences and the doughboy helmet he wore, he invented the first "Hard-Boiled Hat" in 1919. This early hard hat was made from steamed canvas, glue, leather, and black paint, resembling the steel military helmets of the time.
As the use of hard hats became more widespread, with mandatory use on major construction projects like the Hoover Dam in 1931 and the Golden Gate Bridge in 1933, the search for more advanced materials continued. Aluminium hats were introduced in 1938, followed by fibreglass in the 1940s, which was lighter and less conductive. However, it was the introduction of thermoplastics that revolutionised the hard hat industry. Thermoplastics were easier to mould and shape, more cost-effective to produce, and could be used to create more comfortable and stylish designs.
In 1952, the E.D. Bullard Company introduced its first hard hat made from thermoplastic, marking a significant milestone in the evolution of hard hats. This new plastic hard hat improved upon earlier designs, offering enhanced protection, comfort, and affordability. Since then, hard hats have continued to evolve, with advancements in materials, suspension systems, ventilation, and safety features. Today, hard hats are an iconic symbol of construction and industrial work, providing essential protection to workers in hazardous environments.
