What type of hard hats provide protection against blows to both the top and sides of the head?

The type of hard hats that provide protection against blows to both the top and sides of the head is classified as Type II. This designation indicates that they are designed to protect not only from impact on the top of the head but also from lateral impacts, which is essential in various work environments where workers might be at risk of falling objects or hazards coming from different directions.

Type II hard hats have additional features such as reinforced side panels and an extended design that enhances protection, making them ideal for use in construction sites, industrial environments, and other settings where head protection from multiple angles is necessary. This level of protection distinguishes Type II hard hats from those categorized in other types, which may provide limited protection only from overhead impacts.
