What type of impact can a full-brim helmet provide additional protection against?

A full-brim helmet is specifically designed to provide enhanced coverage around the entire circumference of the head, including the top and the sides. The additional brim offers protection not only from overhead impacts but also shields the face and neck areas from elements like the sun and rain. This makes it particularly useful in outdoor environments or situations where workers are exposed to weather conditions.

In contrast, options that mention protection from specific directions such as side or rear impacts do not encompass the overall protection provided by a full-brim helmet. While full-brim helmets can offer some protection from impacts coming from the sides and rear, their distinctive feature is the added coverage they provide against overhead hazards and environmental elements, which makes them more versatile than other helmet types that may focus on a narrower area of protection or specific types of impacts.
