KIMBERLY CLARK SAFETY - JSP 20718 - JSP,Blockhead,Green/891

The Jackson Safety 20718 Blockhead hard hat is a protective helmet molded from HDPE with an eight-point adjustable ratchet suspension, a smooth dome, and a full brim to help protect the wearer from sun and rain. This protective headwear meets American National Standards Institute (ANSI) Z89.1-2003 Type 1 impact requirements for protection from impact striking the top of the head and Class E electrical requirements to reduce the danger of exposure to high voltage conductors. The eight-point adjustable ratchet suspension provides over 30 adjustment levels between sizes 6-1/2 to 8" for a comfortable fit, provides more impact protection than four- or six- point suspensions, and can be adjusted without removing the hat. The HDPE (high-density polyethylene) outer shell is lightweight (16.3 oz.) for comfort, and impact resistant. The suspension straps and nape strap are made of woven nylon, which has a good strength-to-weight ratio and resists mold growth. This hat fits hat coil spring attachment model 37 Hatshield for attachment of any Jackson Safety face shield (all attachments sold separately). Hard hats are personal protective equipment (PPE) worn on the head in workplace environments to help protect the wearer from injuries caused by falling objects, debris, or electrical conductors. These hats consist of an outer shell, typically plastic or fiberglass, and a multipoint suspension system that keeps the shell suspended above the head. More points in the suspension system provide better distribution of the force of impacts for more protection. Suspensions may include either a chinstrap to prevent the hat from falling off, or a nape strap to prevent the hat from sliding forward and falling off when the wearer is leaning forward. These straps are usually adjustable for a comfortable fit, using either a pinlock or ratchet system. A ratchet system adjusts with the turning of a knob on the nape strap and may be adjusted with the hat on. A pinlock system consists of a strap with pins and a strap with holes, and it must be aligned and set with the hat removed.
