Head ProtectionAmerican National Standard for Head Protection- z89.1-2009
ANSI/ISEA 789.1-2009 AND CSA Z94.1-2005 are voluntary industry standards that establish the types and classes of industrial helmets and provide performance and testing requirements for these helmets.
ANSI/ISEA 789.1-2009: is a revision of the standard covering industrial head protecion; this revision supplants the 2003 revision.
CSA Z94.1-2005: is a revision of the standard covering industrial head protection used in Canada; this revision supplants the 1992 revision. These standards include specifications for helmets designed to offer protection from top and/or lateral impact.
The three classes included in these standards indicate the helmet's electrical insulation rating:
• Class E (Electrical): Helmets intended to reduce the danger of exposure to high-voltage electrical conductors, proof-tested at 20,000 volts.
• Class G (General): Helmets intended to reduce the danger of exposure to low-voltage electrical conductors, proof-tested at 2,200 volts.
• Class C (Conductive): Helmets not intended to provide protection from electrical conductors.
