What kind of hazards is a Type I helmet designed to protect against?

A Type I helmet is specifically designed to protect against vertical impacts from above. This type of helmet is commonly utilized in industrial and construction settings where there is a risk of falling objects or equipment that may drop from above. The structure of a Type I helmet features a hard outer shell and an inner foam liner that absorbs energy from impacts, particularly those that occur in a downward motion.

The purpose of this design is to diminish the force of an impact that an individual may experience if struck by a falling object, thus preventing or reducing head injuries. This focus on vertical impact protection distinguishes Type I helmets from other types that may provide different forms of safeguarding, such as lateral impact protection or protection from environmental elements.
