Helmets designed for various industrial and electrical safety purposes are typically categorized into different classes based on their protective capabilities, particularly concerning electrical insulation. Based on the provided information, the classes of helmets include Class G, Class E, and Class C.
Understanding Helmet Classes
These classes distinguish helmets based on their electrical resistance properties, which is crucial for protecting workers in different environments.
| Helmet Class | Electrical Insulation | Proof Test Voltage | Equivalent (Old Standard) |
|---|---|---|---|
| Class G | General (Electrical) | 2,200 volts | - |
| Class E | Electrical | 20,000 volts | Class B |
| Class C | Conductive | None | (Did not change) |
Class G Helmets
Class G helmets, also known as General helmets, are designed to provide electrical insulation. They are proof tested at 2,200 volts, offering protection against lower-voltage electrical conductors. This class is suitable for general use where minor electrical hazards might be present.
Class E Helmets
Class E (Electrical) helmets offer a higher level of electrical protection. This class is equivalent to the old Class B standard. Class E helmets are proof tested at a significantly higher voltage of 20,000 volts, making them suitable for environments with potentially higher voltage electrical hazards.
Class C Helmets
Class C (Conductive) helmets provide no electrical insulation whatsoever. The alpha designation for this class did not change from the old standard. These helmets are typically used in environments where there is no risk of electrical contact but head protection is still required for impact or penetration hazards.
These classifications help ensure that workers select the appropriate head protection for the specific hazards they may encounter on the job site, especially concerning electrical safety.
