Msa 10057443 Hard Hat Type 1 Class E V-gard Slotted Cap

Product Description

The MSA 10057443 is a Type 1, Class E hard hat built on the V-Gard slotted cap platform, designed for impact and electrical hazard protection on commercial and industrial job sites. Constructed from high-density polyethylene, the shell resists impact while staying lightweight at 0.75 pounds. The 4-point pinlock suspension system made from nylon allows quick, tool-free head-size adjustment from 6.5 to 8 inches. This hard hat meets ANSI/ISEA Z89.1-2014 and CSA Z94.1-2005 standards, making it appropriate for both U.S. and Canadian job site compliance requirements. Electricians, HVAC technicians, plumbers, and general construction workers use this model wherever Class E electrical protection is required.

The V-Gard slotted cap style is suited for residential and commercial construction, industrial maintenance, utility work, and any application requiring overhead impact protection with accessory slot compatibility. The slotted brim accepts clip-on accessories such as face shields, earmuffs, and visors. This model carries no graphics and ships in yellow, making it easy to identify on site. It is commonly issued as standard PPE on job sites requiring ANSI Type I head protection, which covers top-of-head impact but does not address lateral impact.

Installation Notes

Issued and fitted by a safety officer or the worker prior to entering a job site hazard zone. Inspect the shell and suspension for cracks, dents, or fraying before each use and replace if damage is found. Do not drill, modify, or paint the shell, as doing so may compromise impact and electrical protection ratings. Replace per manufacturer service life guidelines or immediately following any impact event.
