Based on current safety standards, what was previously known as a Class A helmet is now designated as a Class G helmet. These helmets are designed to provide protection from electrical hazards.
According to safety standards referenced, Class G helmets (formerly Class A) are intended to protect against falling objects and reduce the danger of exposure to low voltage electrical conductors. They provide protection from electrical exposure up to 2,200 volts.
Understanding Helmet Classes
Safety helmets, often called hard hats, are categorized into different classes based on the type of protection they provide. The primary classes related to electrical protection are:
- Class G (General): Provides protection against falling objects and exposure to low voltage electrical conductors, offering insulation up to 2,200 volts. This is the class that corresponds to the former Class A.
- Class E (Electrical): Provides protection against falling objects and exposure to higher voltage electrical conductors, offering insulation up to 20,000 volts.
- Class C (Conductive): Provides protection against falling objects but offers no electrical protection.
Key Features of Class G (Formerly Class A) Helmets
As noted in the reference provided:
Class G (Formerly Class A): General Use (limited voltage - non-conducting) intended to protect against falling objects and reduce the danger of exposure to low voltage electrical conductors. They provide impact and penetration resistance and protection from up to 2,200 volts.
This means that a helmet classified under the old Class A standard, or the current Class G standard, offers the following key features:
- Impact Protection: Protects the wearer's head from falling objects.
- Penetration Resistance: Resists penetration by sharp objects.
- Electrical Protection: Provides a level of electrical insulation, protecting against contact with low voltage sources up to 2,200 volts.
This class of helmet is suitable for general construction and utility work where there is a risk of head injury from impacts and limited exposure to electrical hazards.
