New Thermal-E Caps from MSA provide head protection for hightemperature, electrical/high-voltage, and other dielectric applications requiring NFPA70E-2009 compliance. Lightweight, durable, slotted caps are ideal for use in utilitywork, welding, steel mills, mines, and foundries. Thermal-E Caps meet or exceed allapplicable requirements for a Type I helmet (top-impact) as outlined in ANSI/ISEAZ89.1-2009, 94.1-2005 (Class E, electrical/high voltage) and NFPA 70E-2009.
