What type of hose does not require static protection if certain conditions are met?

The correct choice highlights that a conductive or non-conductive hose does not require static protection under specific conditions. This is primarily due to the material properties of the hose. Conductive hoses are designed to dissipate static electricity safely, thereby preventing the buildup of static charges that can lead to sparks or potential ignition sources in hazardous environments, especially when working with flammable gases or liquids.

In contrast, non-conductive hoses are typically made from materials that do not allow the flow of electricity. However, if certain operational or environmental conditions are met—such as ensuring that the hose is not experiencing friction that could generate static—static protection may not be necessary.

Understanding the implications of using different types of hoses in terms of their ability to conduct or insulate against electricity is crucial for ensuring safety, especially in industries dealing with compressed natural gas or other volatile substances. This knowledge allows the driver to make informed decisions about the equipment used during operations.
