When entering a void or confined space, it is crucial to adhere to safety protocols to ensure the well-being of personnel. The correct choice encompasses multiple important safety measures.

Having a gas free chit posted at the entrance serves as an official record that the atmosphere within the space has been tested and deemed safe for entry. This is a critical first step to prevent accidents due to unsafe air quality.

Requesting free assistance also highlights the importance of having support in case anything goes wrong. This ensures that there is backup ready to provide help, making the operation safer.

Being cautious of explosive and toxic gases is fundamental when working in confined spaces. These areas can accumulate harmful substances that are not always visible or detectable without the proper equipment. Therefore, acknowledging this risk and taking preventive measures is essential for safety.

These elements combined emphasize the comprehensive approach to safety when entering potentially hazardous environments, which is why the selection that includes all of these aspects is the best choice.
