Hard Hat

A hard hat is a type of helmet predominantly used in workplace environments, such as construction sites, to protect the head from injury by falling objects, impact with other objects, debris, bad weather and electric shock. Inside the helmet is a suspension that spreads the helmet's weight over the top of the head. It also provides a space of approximately 30 mm (1.2 inch) between the helmet's shell and the wearer's head so that if an object strikes the shell, the impact is less likely to be transmitted directly to the skull. Sometimes the helmet shell has a mid-line reinforcement ridge, which strengthens it against impact.

Blue-collar workers, especially union shop construction workers, engaged in occupations that require protective equipment are sometimes metonymically referred to as "hard hats".

A bump cap is a lightweight kind of hard hat with simplified suspension or padding in lieu of suspension and having only a chin strap. It is used where there is a possibility of scraping or bumping one's head on equipment or structure projections, but is not strong enough to absorb large impacts, such as from a tool dropped several stories.

Famous quotes containing the words hard and/or hat:

    Conceptual relativism is a heady and exotic doctrine, or would be if we could make good sense of it. The trouble is, as so often in philosophy, it is hard to improve intelligibility while retaining the excitement.
    Donald Davidson (b. 1917)

    The agent never receipts his bill, puts his hat on and bows himself out. He stays around forever, not only for as long as you can write anything that anyone will buy, but as long as anyone will buy any portion of any right to anything that you ever did write. He just takes ten per cent of your life.
    Raymond Chandler (1888–1959)
