General purpose front-brim (Type 1, Class E) hard hats are non-vented and they have a front brim to protect the face from sun, reduce glare, and help shed rain. Type 1, Class E hard hats protect wearers from vertical impacts and high-voltage conductors (up to 20KV). These hard hats are used by construction workers, road crews, and other workers as required by OSHA.
