Which types of hard hats are included in head protection?

The correct answer highlights the types of hard hats that are designed to protect against specific hazards present in construction and industrial environments. Types C, G, and E refer to hard hats that offer different levels of protection:

• Type C hard hats provide lightweight protection and are typically used in environments where impact protection is necessary, but electrical protection is not required.

• Type G hard hats are designed for use in environments where the risk of electrical hazards is prevalent, as they provide insulation against low-voltage electrical shock.

• Type E hard hats are intended for use in high-voltage electrical environments and provide even greater protection against electrical hazards.

These classifications are important for ensuring that workers select the appropriate hard hat for their specific work conditions. The other provided options list types of hard hats that do not correspond to the classification system outlined by OSHA regarding electrical and impact protection, which is critical for ensuring worker safety in the field of construction and industrial work.
