Which type of chemical protective clothing offers protection from both gases and vapors?

The correct choice indicates a type of chemical protective clothing that is designed for total body splash protection. This type of clothing is specifically constructed to provide a barrier against chemical splashes, including both liquid forms and the potential for gases and vapors to penetrate the clothing. Such garments are often made of materials that are impermeable to hazardous substances, thus ensuring a high level of safety for the wearer in environments where chemicals are present.

The emphasis on total body protection suggests that this clothing is not just about protecting selected areas but provides comprehensive protection from exposure to harmful substances in various forms. Thus, this option aligns with the requirement for clothing that can guard against both gaseous and vapor threats in addition to liquid splashes, making it well-suited for use in scenarios where there is a risk of chemical exposure.

Other options may refer to specific equipment or protective measures that do not fully encapsulate the dual protection of both gases and vapors along with liquid hazards, focusing instead on either respiratory protection or partial protective solutions.
